There are usually 2 options: an online marketplace or a store (a company that sells computers). Buying an old laptop from a store or company is usually more expensive but with a short warranty period, so you will be assured of product quality. Buying at the classifieds on the internet is generally more risky but cheaper. When buying, look for sellers that are rated well by the community on the internet and update products regularly. If the computer has a problem, these sellers will be happy to exchange it in order to avoid negative feedback affecting their reputation. That is the beauty of the online shopping market.
To buy an old laptop like that Picture 1 When buying, the most important thing is to consider the screen because this is the most expensive thing of a laptop if you have to replace it. Check if the laptop has bruises on the screen. Bruises are brighter or darker areas on the screen, which are normally difficult to identify. To detect, it is necessary to switch the laptop's desktop to black. Good screen will only have uniform black layer, no white dots. If you find a screen with many white dots, do not buy.
After the screen, check the slots and ports such as Bluetooth wireless ports or Wifi. There are a number of slots and ports that connect directly to the motherboard will be expensive to replace. If a USB port fails, it is not worrisome because there are still 3 remaining USB ports. The headphone jack is also broken, so it can be replaced with a Bluetooth wireless headset. Next, check the hard drive for errors. Remember that replacing hard drives is not expensive. Behind the hard drive is an optical drive. The simple test is to test the discs that this optical drive supports such as CD-R, CD-RW, DVD-R or DVD-RW. Finally check the battery time. If the battery runs out too quickly, ask the seller to lower the price to replace the new battery. Replacing new batteries for laptops is quite expensive.
