So far I have mentioned many times that buying a laptop is a lot to purchase . It is true that the cheapest computer you can buy a longer per-thousand five hundred zlotys ( do not count here netbook purchase , which will get a smaller amount ), but it is a simple laptop(
laptop Battery) and for many applications may not be sufficient . Therefore, having a limited budget , we can attempt to purchase second-hand computer . This solution will allow us to purchase a laptop with a better setup for a much lower price than in the case of a new , comparable configuration.
But before you buy your computer , you need to know some important principles, which should strictly observe spending your hard-earned money.

Dell Inspiron E1405 Battery), watch out , because the equipment can come from theft.
Before you buy , try to inquire about the origin of the laptop vendor . If possible , let the seller show you the invoice of purchase of the computer. Ask also about the serial number of your laptop and check the manufacturer's website if the device is not accidentally hit it on the black list . For example, all Dell records stolen laptops(
XPS m1210 battery) and we can see whether the device is reported as stolen .
If you buy on the auction or other auction sites , read the comments they received the vendor. If the user profile has no comments and the equipment is suspiciously cheap, be careful with this purchase. The following figure presented the views of the auction , in which the seller offers a laptop(
HP 510 battery) at a price representing only 50 % of its store of value. In addition, the information shows that such cheap computers dealer has five .
Make sure you get a laptop(

Remember that buying stolen equipment, you may be accused of receiving stolen goods, and for that the penalty of imprisonment or heavy fine .
Check the specification of purchased computer and compare it with data on producer
Ask the seller to provide the serial number of your choice laptop(
VGP-BPS9/B). Then check on the configuration of your laptop manufacturer . It just so happens that almost every manufacturer will identify the parameters of the computer after its number .
If the configuration of your laptop , you want to buy , is different from what is given by the manufacturer on your website, try to find out what changes have occurred in the configuration. Ask whether any changes occurred in the configuration of your computer and what were their causes .
Upgrading RAM or exchange the largest capacity hard drive is not a problem and often result from a desire to improve the performance of your computer. However, the change of other components , or their absence may indicate that the seller has decided to be removed and sold separately or you're in front of a computer

If you choose to have a specific laptop model , check to see what opinions he has received from people who użytkowały it for a long time . You can type the name of the device and its model for a Google search.
Pay attention to the sustainability of the housing, the cooling system and the unreliability of other components of your laptop(
HP Compaq nx9420 battery). Find out also whether the users have had with a computer model of some other problems. will also be useful knowledge about the operation of the service and any warranty repair costs .
Check the condition of the computer case
Before buying a computer case look carefully and see if it can not see the cracks, traces of glue and other permanent damage.
If the computer's casing is cracked , it means that the laptop(
Fujitsu FPCBP136 battery) could fall , or simply been badly used by a previous owner . It also happens that some models of laptops bursting , even during normal use , which is proof of poor quality equipment.
