Depends on your budget , and 10,000 the following recommendations to buy Lenovo , more than 10,000 recommendations to buy Dell .
Frankly , if you budget is not too high , I do not recommend these two .
Lenovo notebook repair rate is out of the Church 's high, I have bought a Lenovo books , 20,000 (2001) , spent less than six months , drive on the bad ( the middle seat out Chuck 's site acer travelmate 4230 battery
, I Used in many notebooks, never seen that brand of drive that the problem occurred ), to customer service , that can not repair , changing drive . After a year, once I was writing the document , a sudden hard drive crazy ring , then hang up , say can not find the boot disk , go to customer service that is hard to hang ( the kind of data can not be restored ) . Every time I go to Lenovo's customer service was a great Yeah, is not to repair laptop repair desktop . Then angrily changed a Sony ( do not despise me, I use Japanese products , is now no need, to use the company issued IBM), with three or four years , not one thing wrong .
Besides Dell , Dell is the world's No. 1 selling brand of computer . Why is the first , because the things they are cheap . Dell to say that they are direct sales , distribution channels than any other brand of short , so cheap . But everyone knows in the end profit with such a number of things , your channel is short, but other people's channels are not long ah . Brand computer manufacturers before doing a few left now has ? Lenovo acquired IBM 's was , COMPAQ acquired by HP , why, because they do not make money . Why Dell does it bigger and bigger ? Because Dell knows that most people who buy computers just think enough on the line, they will not pay big bucks to buy high-end machines ( foreign and domestic non- DIYer like people DIY is the ultimate pursuit of performance ), and high-end machines The user is generally large enterprises. Therefore, the low-end products, material is saved, in doing so, not only lower prices, and profits even higher . Must use good ingredients and high-end products , profit ,acer travelmate 5710 battery
though a small point, but after all, less shipping . So what should only buy high-end Dell products . That much of the point , talk about Dell's notebooks . Really good high-end Dell notebooks can be said that IBM and HP 's cost-effective than the higher . However, it is too low-end notebook on the times. I once accompanied Zhongguancun buy books to learn , finally, I bought the Asus students in the inspection , we chatted up on the boss , asked him ASUS quality of books , but also talked about other brands of books , talk about To Dell 's low-end machines , the boss look a look of contempt , when we think he sensed before, but he took a one Dell laptop (model not remember , when the price of that section 9200 or so) over (they Company Owners to Asus , but also for other brands of books , such as IBM, Lenovo , Dell , where he has ), on the table , a little finger pressure force in the shell on a shell on the deformation of the ( Khan a first ), This quality also talk about portability . Other brands (including associations ) do not have this.
So I recommend landlord , you do not buy these two . But if the two brands , then Italy , and your money and not much , then you buy a Lenovo .
Also recommend some brands of notebooks, ASUS , ACER, NEC quality is very good . BENQ not used , but the general feel . Toshiba If you can buy the Japanese original 's good, if not buy , do not take into account , and his agent in China is Lenovo . IBM and HP best , acer travelmate 5320 battery
that is more expensive . Korean brands do not consider them altogether , is rubbish . SONY good shape , performance is okay, but not recommended , too expensive.
Landlord to buy a Heart last living notebook .

What to buy second hand notebook should be noted that the problem ?
With small portable notebook advantages , has been highly favored people . Although compared to before , the prices of notebook computers a lot , but still relatively expensive , a lot of limited budgets friends all eyes are on the second-hand notebook market . But since the origins of complex second-hand laptop , old and new Condition varies , sell notebook business has no shortage of self-propaganda, so pick a second-hand notebook computers have become a big problem . Here I briefly a few selected second-hand notebook note acer travelmate 4200 battery
, we want to purchase help.
Note battery life issues
Notebook computer battery is the source of life , but also the most rapidly aging laptop accessories in one of the market at present most of the second-hand laptop are using the products two to three years , while an ordinary lithium batteries in use Two to three years after the appearance of aging will more or less , and some life time only over one hour . Some merchants will be replaced before the sale of second-hand laptop battery batteries, the surface looks to extend battery life time , but this is a desirable behavior , because laptop battery 's internal structure and circuitry are more complicated Replacement batteries battery packs a greater chance of failure , and it is time to use a few days after the cell performance dropped dramatically , there may even damage the notebook body , it is not recommended to purchase replacement batteries for notebooks .
Of course, if you buy a laptop to use only as a fixed , but also aspects of the link power supply , then the battery problem becomes less important , can stand more than an hour of battery does fit to use as a UPS power supply .
Screen shaft can not be ignored
In addition to tablet computers, almost every laptop should have the screen shaft , and shaft each time the laptop is to be worn mechanical parts , so wear is second-hand laptop screen hinge is an important issue selected . If the shaft is too loose , it would be very awkward to use notebook .
Shaft can not be hidden elastic , consumers can be seen directly , but those are usually sold with notebook JS "a song that can be adjusted tight "as an excuse to deceive consumers. Some laptop screen hinge loose, can indeed be adjusted by adjusting the screw , but most of the laptop screen is not adjustable shaft when the shaft after the middle of the damping material wear can only replace the entire shaft . Even those who can adjust the notebook , because the damping material has been worn , so not too much time on it will become loose . Imagine a laptop screen in the course of a sudden collapse that would be how it feels .
Highlights of the screen , dead pixels and dark spots
Bright and dead pixels LCD display is quite familiar to most consumers , but for the screen dark spot is not everyone know about the . Dark spots more subtle than the bright and bad points , but also more affecting normal use. Classes are small dark beans so much , there may be a big bigger than a thumb , and the bright and dark spots are different classes is only a partial dark colors darken slightly , do not pay attention have been observed in the light color does not come out the next , and replaced with deep color Background could not detect . Dark classes There are two main reasons for the formation of , first, because external compression caused by such a small area of dark spots , the middle color depth, some of the outer relatively normal , thin and light notebooks in the more common. Another dark spot is caused because the LCD screen aging , this relatively large area of dark spots , and may continue to deteriorate. Because of the color than the surrounding dark spot just a little deeply, it can easily be acer travelmate 3260 battery
crafted desktop hidden away . So many times in the selection of the notebook background for a few test machines , or use a professional testing software to check , for example Noika Ntest, it can find the bright spot , color cast and so on.
In addition , LCD brightness drop is naturally used laptop common problem , generally can not be avoided , if not very obvious is also acceptable , but if found to have clear yellow liquid crystal panel is best not to buy .
Note See peripherals and interfaces
Used notebook peripherals and interfaces is also very high failure rate zone , keyboard interface, access to undesirable things not working or have occurred, these peripheral interfaces are very important and many consumers are often overlooked in the inspection of these machines Problem . Among the most frequently used interface should be USB interface, audio interface and network interfaces , especially USB interface seems to be more important. USB interface, common interface, the failure is not voltage , in which case such as mouse and USB devices without a power supply can not normally use, but with power equipment such as printers , scanners , etc. can be used normally. So I suggested that in check when the USB interface, the mouse can bring U disk or other testing , and other interfaces , such as LAN , Modem, Speakers, serial port , parallel port , PCMCIA, MIC interface and infrared interface, better try it .
Keyboard , mouse is the most important computer input devices, frequency of use is the highest , most laptop keyboards with special keys designed 83 or 86 , must try to buy every time a button is sensitive and feel is comfortable, key bits Still flexible , handwriting is clear . Keyboard failure is a very serious problem , although not on the keyboard keys are used for each , but they are indispensable. When you find one key failure when the business may tell you it was a " humble " in the key, as long as the replacement of a key run on the line . But often not the case , a key may need to replace the entire keyboard may cause , and replace the notebook 's keyboard usually requires spending a few hundred pieces , is not worth it. In addition, as most people are using the notebook to use an external mouse , so that the notebook touchpad not essential , it is not true , imagine the day you need to forget how to bring the mouse over it .
More importantly, internal injuries
Beware of overclocking the CPU. Processor will always be the core of computer equipment , so when purchasing notebook must be taken seriously enough , the best brands in the choice of a model acer extensa 5620g battery
of a good second-hand after the Internet look up the standard laptop configuration, note that CPU, Frequency can also use the testing software to test some of occupation . CPU performance is directly related to the performance of the whole machine , in order to satisfy the second-hand laptop can use a given period , as proposed in the options when choosing the time near the factory , high frequency machine , because the notebook computer processors typically Are not upgraded .
The hard disk has bad sectors alert . Hard drive itself is a relatively fragile equipment , but also vulnerable parts of the notebook , there are bad sectors in hard disk for the machine 's overall stability rather negative , if there are abnormal ring or disk using the procedure in sudden drop in speed , Would have to be careful. Market, many second-hand hard drives used in notebook computers are relatively old, and generally 4200rpm, 512KB cache hard drive or even an older model , capacity, mostly 20G the following . If you feel that in addition to the hard disk , the machines were satisfied with all aspects of the case, you can consider replacing the hard drive of a new , after all, the process of using notebook stored in the hard disk is very important in the Shujuxiande .
Memory should not be too small . The size of the memory capacity directly affects the performance of the whole play , currently on the market of second-hand laptop memory capacity 32MB to 128MB in between , there are a few 32MB less in when purchasing as we choose larger than 64MB , it is best 128MB or more , perhaps their would be more appropriate to upgrade to 256MB . Pay attention to the time of purchase Zexu notebook using a kind of memory, whether the matching model upgrade.
Warranty issues also need attention
The greatest disadvantage of second-hand laptop may be its warranty issues now. Although some second-hand laptop can also provide after-sales service business , but the limitations of this service is too small , but time is often very short , usually only a short month. And basically most of the second-hand laptop no after-sales service , if the laptop broke down , you can only pay for their maintenance costs . However, as is generally the situation , I can only recommend that you try to select the larger size , more machines , accessories and complete business point of purchase, such businesses are often good reputation , is also easier to repair them .
Summary
Although the notebook has a relatively cheap second-hand prices, cost is also high, but still have to consider when buying second-hand laptop you buy the motives and purposes . Some people are to play the game , some people just deal with the document , on the Internet like the , in addition to a number of advertising design or video editing is like a pair of notebook computers in the required Bi Jiao Gao Yi Wai , Pu Tong 's Peizhiacer extensa 5220 battery
basically Dunengmanzu requirements . Therefore, the time of purchase must be to choose according to their own needs , such as the type you want to play like , take a more than two thousand dollars Maige Pentium II 's second-hand laptop is sufficient. In short , the second-hand laptop purchase, require rational analysis of their own needs , the courage to accept their shortcomings , dare to face after the failure to buy .
, we want to purchase help.

How laptop batteries batteries for core ah ?
Notebooks use a longer period of time, prone to the problem of declining battery capacity , resulting in notebook battery life time . This is mainly internal batteries battery failure caused by aging or . Serious cases , the use of battery calibration procedures or repeated charge and discharge the battery problems are solved . For this problem , there are many acer btp-arj1 battery
fans that the battery case open , find and replace the batteries can fail to solve the problem . Reality Is that true ?
Replacement batteries should be cautious
Since many laptops now use lithium ion batteries, and lithium-ion battery life is basically constant , with the number of the charge and discharge . So if you often use battery -powered notebook , 1 to 2 years , the battery is easy to achieve because of the internal life of the batteries fail . While we open the battery when testing batteries , is shown in one or two batteries damaged . However, other batteries have largely been a failure even if you change batteries , the battery will return to normal in a short time , will soon fail for other batteries and make the entire battery can not be used again .
So, the notebook 's internal battery replaced all can solve the problem? In fact, this is difficult . Because the original battery , its internal batteries is through precise matching , and therefore the capacity of batteries , terminal voltage and internal resistance of a good consistency . We bought in the market, batteries , and have not been tested and matched , we can not for the amateur conditions, matching batteries , so its capacity, internal resistance and other parameters will inevitably vary. In the internal battery , the batteries are charged together after the series (in most laptop batteries , is divided into two groups of 8 batteries , 4 series and then parallel to form a battery pack ), because the battery charge Current as of which the smallest capacity will first fully charged batteries , while not sufficient because the other battery , the battery terminal voltage fail to set the voltage , the charging circuit will continue to charge the battery pack . In this way, the original fully charged batteries will overcharge . To reduce the charge time , laptop charging circuit of the charge current very large, so too will charge batteries when the tremendous heat , making batteries the liquid temperature increases, the pressure increased, the internal electrolyte easily dry up or overflow , Leading to further decline in capacity batteriesacer extensa 5210 battery

We need to reset the smart chip can solve this problem, but amateur conditions, we can not reset the smart chip . Therefore, replace them when the batteries may cause permanent damage to the battery .
So how do we solve the battery problem? Of course the best way to buy a new original battery , but a new original battery to hundreds or even thousands , so spending is too high, more than many consumers can afford.

, 1 to 2 years , the battery is easy to achieve because of the internal life of the batteries fail . While we open the battery when testing batteries , is shown in one or two batteries damaged . However, other batteries have largely been a failure even if you change batteries , the battery will return to normal in a short time , will soon fail for other batteries and make the entire battery can not be used again .
So, the notebook 's internal battery replaced all can solve the problem? In fact, this is difficult . Because the original battery , its internal batteries is through precise matching , and therefore the capacity of batteries , terminal voltage and internal resistance of a good consistency . We bought in the market, batteries , and have not been tested and matched , we can not for the amateur conditions, matching batteries , so its capacity, internal resistance and other parameters will inevitably vary. In the internal battery , the batteries are charged together after the series (in most laptop batteries , is divided into two groups of 8 batteries , 4 series and then parallel to form a battery pack ), because the battery charge Current as of which the smallest capacity will first fully charged batteries , while not sufficient because the other battery , the battery terminal voltage fail to set the voltage , the charging circuit will continue to charge the battery pack . In this way, the original fully charged batteries will overcharge acer extensa 5210 battery
. To reduce the charge time , laptop charging circuit of the charge current very large, so too will charge batteries when the tremendous heat , making batteries the liquid temperature increases, the pressure increased, the internal electrolyte easily dry up or overflow , Leading to further decline in capacity batteries , there swelling or even explode . The total capacity of the battery capacity by which the smallest batteries that decision , and this will result in a vicious circle , by repeatedly charging and discharging , the entire battery capacity will significantly decline , resulting in time laptop use .

Meanwhile, the number of notebook batteries in order to prevent unauthorized users to open to replace batteries, has a smart chip protection and anti- open end line . As long as the battery case open or batteries from the circuit board to remove the battery , intelligent battery protection circuit will stop the output . Even if we re- cell batteries back together on the circuit board or battery case , the intelligent protection chip still can not recover . In this way, the battery would not work out . We need to reset the smart chip can solve this problem, but amateur conditions, we can not reset the smart chip . Therefore, replace them when the batteries may cause permanent damage to the battery .
So how do we solve the battery problem? Of course the best way to buy a new original battery , but a new original battery to hundreds or even thousands , so spending is too high, more than many consumers can afford. However, there are some professional notebook repair station, its equipment and technology are good , and some repair stations and manufacturers of batteries there is long-term relationship , the battery can be carried out on the factory precision matching . This would ensure the maintenance of quality . In these places for the price of batteries is about 300 yuan , although the replacement of batteries than the price of their own is higher , but will keep the battery long-term use . In addition, some service stations also had the battery for six months service warranty . And we use this in six months , just make sure the battery a hundred times Zuoyou charge and discharge , and cell capacitance stability in the Qi Jian say and battery Jiuhui become stabilized, the Butai Rongyisunhuai the .
The trick to maintain the battery
In any case, replace the batteries do not need our small price to pay , so we should pay attention in daily use to maintain the battery to extend battery life.
To protect the battery , first to reduce the number of battery , that is when there is electricity ,acer btp-arj1 battery
as much as possible do not use the battery . This can reduce the battery charge and discharge times and prolong battery life. While this caused some inconvenience to use , but think each time you use the battery will need to pay two dollars , it still CAREFUL IN THE SUMMER .

How to choose a good laptop computer?
Selection of the top five notebook PC experiences strategy and several
Currently , the domestic notebook computer market into the market capacity , sales volume double- stage high-growth . According to CCID Consulting 's statistics show that during the first half of this year , notebook PC market capacity reached 36.5 million units , up 44.3% , in the overall PC market share for the first time in more than 9 %; same time, the notebook computer is to the public , showing Out an alternative to desktop computers into IT industry, " the leading stocks, " momentum.
Freshly by the end of the face of the major manufacturers an attractive promotion, those who have been hold out to buy a good notebook platform activities of consumers began thinking about this. But in the face , " continued the war , " the notebook market , how in the " Big Wave in Gold "mean ?
Here to introduce you to several experiences, want to help you choose .
CPU enough for the principle of reasonable
Select your favorite a laptop , and buy household appliances , daily necessities, different. Because notebook has its particularity , we choose , we might ask yourself is what bought used .
If you are a regular employee , usually work only on the Internet , do some general document , presentation slides and so on. Then you do not need to pursue "G era " feel. Celeron plus a common memory and a big enough hard drive , enough to make you " surfing , typing , "correct .acer blue aspire one zg5 battery
If you are a " gamers ", or do graphic work produced . Then you can choose to P3, P4 of the "G" of the times . Large increase in memory and hard drive external displays . This is for you " lightning speed " -like speed while , will give you a very "cool "feeling .
Also to remind my friends, when shopping for desktop PCs must find out whether CPU MoblieCPU, because some manufacturers to reduce manufacturing costs , used in notebook computers and power high heat desktop CPU, If without special treatment , it is difficult to run a long time stability . You can use Intel 's special program "Intel processor Frequency ID Utility" to test the CPU type , and whether the CPU supports "Speed Step" technology .
" thin and light "mainstream fashion
Do not think that the price and configuration of all the factors that measure the notebook , in fact, there is a problem can not be ignored is the notebook 's mobility. Our aim is to buy a notebook , " heavy on the light house " , in general, all plug into the notebook market , Guangruanhuhuan and full built-in three categories.
At present, the notebook is not only in the configuration performance was generally improved , but also in product emphasizes the appearance of the volume on " light . " Thin and light notebooks on the market has become a fashion , a variety of ultra-thin notebook products is endless . But worth mentioning is that BOE launched T series ultra-thin notebook though built-in optical drive , but weighs only 1.7KG.
Display to monitor
It was observed that many of my friends in the purchase when the laptop is most concerned about the size of the display . TFT display is currently the mainstream products , and its advantage is the high brightness and contrast , screen response speed, viewing angle , rich colors, but the TFT display relatively expensive . Now the market size notebook display several main 12.1,13.3,14.1,15 inch size , the relative price there should be a large gap , and friends can be based on their economic ability to choose the right display . In a time when buying a laptop should pay attention to look at the display 's brightness and contrast is appropriate , whether the response time display look normal VCD playback screen is smooth , indicating whether the rich colors can be viewed on another CRT monitor with a picture If the display more similar to the description screen positive.
Hard drive and memory can not be too small
As for the hard disk and memory size , should be as required . At this stage, entry-level notebook computer hard disk capacity should be around 10GB of memory should not be less than 128MB; while in the high-end notebook hard disk capacity should be around 2040GB of memory is not less than 256MB. Also at the time of purchase laptop notebook should look at the upgrade and expansion capabilities, whether there is surplus of memory slots , CPU can upgrade for future upgrade or expand your computer's hardware ready.
Lithium battery is better selection
Currently, the batteries used in notebook computers are mainly two kinds of nickel-hydrogen batteries and lithium batteries . NiMH batteries are cheap, but there is memory effect , and in the same capacity under the weight ratio of lithium , while on the lithium battery has no memoryacer black aspire one zg5 battery
effect , light weight, long power advantages , has become a standard notebook computer batteries . However, lithium batteries used in notebook computers because of different manufacturers in the power of time that there are some gaps , and friends in the purchase process should be noted that different brands on the difference between the battery , the best among several brands compare .
Volume : If you 're on the road most of the time , you may choose a light product. However, in portable performance has been enhanced to make necessary compromises in other areas - such products are often smaller screens , processing performance is not very strong , often provide an external optical drive. If you need a full-featured notebook PC or Apple , then you might consider the kind of heavyweight of all built-in system . This desktop replacement 's battery life is very poor , but they are often equipped with powerful processors , DVD burning equipment and large-size wide -screen LCD.
LCD: There is no doubt the vast majority of products are 14.1 -inch screen offers a resolution of 1024 * 768 , of course, a very small part of the performance will be better ; larger 15-inch LCD can provide desktop LCD monitors closer The use of experience , and also have higher resolution ; wide- screen 15.2,15.4 and 17-inch products are slowly emerging , can support resolutions up to 1680 * 1050 . Of course, the ultra-portable notebook , often with 12.1-inch or smaller LCD screen , but its resolution is generally a level at 1024 * 768 .
Optical drive: Generally speaking, most notebooks are now available Combo drive, DVD-ROM is read and CD-R/CD-RW burning products. Began offering more and more products DVD burning equipment to replace Combo, supports multi-format recording equipment and can burn CD-R/CD-RW, also can burn DVD-R/DVD-RW/DVD-RAM/DVD + R / DVD + RW.
Pointing device : most of the new notebook computer products tend to use the touchpad pointing device Zuo Wei , this design in use feel closer to the mouse operation, the location, movement and sense of direction on are easy to operate , but there are some products Provides " an area of " small Pointing stick , this design in the business notebook such as IBM, DELL 's products more common.
Memory: As hard drive capacity , as the size of your memory needs and you want to use this notebook to complete the task of closely related , in general, 256MB is the standard configuration, a number of new products introduced as a standard capacity of 512MB Distribution , we need to remind you that, according to the actual situation to choose , do not waste.
Network: Although some products or omitted infrared modem interface to reduce the size of the entire system , but basically the current laptops are going to be 56K modem , 10/100M Ethernet , infrared interface as the standard interface . All Centrino notebooks are available with 802.11b wireless module , but that does not mean that all laptops have this feature, preferably prior to purchase access to the configuration list .
Similarly , most systems will Bluetooth as an option , but a small part of the new products as the standard. All current Apple laptops have built-in wireless antenna , but you still need to buy a separate AirPort (802.11b) or AirPort Extreme (802.11g) card .
Hard drive : Now , 20GB hard drive standard has been replaced by a 40GB hard drive , larger capacity drive - 60GB or 80GB of products usually as an option or a second hard drive to be included in the list . In fact, taking into account the limited upgrade notebook space, select a larger hard drive is often wiser .
Graphics Card : Graphics card processing performance is often poor in the performance of notebooks and desktops contrast the role played hamstrung . If you need good multimedia performance , it supports DX9 the ATI Mobility Radeon 9700 and nVidia Geforce GO FX5600 series of mobile graphics chips can provide so far the closest desktop graphics performance , if you think that these configurations will be some waste , then the Geforce GO FX5200 and Mobility Radeon 9600/9200 is also a good choice , for the integrated chip is often able to provide a balanced performance.
Scalability : The new mainstream notebook will offer a series of interface or slot - USB 2.0, IEEE1394, PCMCIA, S-Video and VGA output , as in the mold design and configuration , few have other expansion solution Therefore, a notebook should provide at least two USB2.0 ports ( three , of course better, four would be ideal ) and a 1394 . Add a card for unlimited , GPRS or Bluetooth card for card , PC card slot is also essential.
Processor: The Windows platform system , AMD and Intel have provided low- voltage, low -power processor to sacrifice some performance for longer battery life. Intel 's Centrino mobile technology (including the Pentium M processor , 855GM/GME/PM chipset and Pro Wireless 2100/2200BG wireless module ) can be without sacrificing battery life , under the premise of providing a more excellent performance.
Apple laptop that , iBook and PowerBook G4 processors are used , although good enough before the G3 , but the latest G4 processor or between performance and power consumption to find the best balance.
Also need to consider are:
Bundled software : desktop computer usually a series of value-added software products as part of the whole , notebook vendors can not so generous , when you see a new system, often able to see the operating system software and some drivers Software , other software will typically include DVD player software , CD / DVD burning software , anti- virus software , and a Windows XP system CD , and some products will provide system recovery CD , as office and multimedia software, often as an optional Configuration .
Computer Package : Do not overlook the importance of laptop bag , it may not appear in your main consideration when buying them - processor frequency , drive type, and scalability are often attracted your attention , of course, battery life Time is also an important factor. But now that those notebooks with a smooth silver surface is very easily scratch other inappropriate computer bag . So most of the notebook computer has a dedicated computer bag , do not forget this in the purchase of additional accessories , if the product is not supplied , then the best to buy a specialized .
Sound System : The sound system , the general mainstream notebook PCs will be two small stereo speakers placed inside the machine , providing not very good stereo effect , but some desktop replacement notebooks can provide speakers with a bass 5.1 -channel surround sound .
Warranty and after-sales service : good laptop products are often able to describe some of you can not thinkacer batbl50l6 battery
of issues such as warranty and after-sales service . Service is generally 1 year -3 , the shortest warranty period should also be able to reach 12 months , but in general , most manufacturers will provide three years of quality assurance , which includes 12 months parts and labor , the latter 24 months labor services are only available free of charge , parts extra. We propose to see the Terms of Service at time of purchase , be aware of , such as DELL on their website clearly expressed standards of service charges for different circumstances , so that a glance .
