subject: Lcd Screen Charges Laptops Price [print this page] One of my friends came to ask me about how to identify the quality of a second hand laptop. He wanted to buy a Compaq Presario (CQ50 AC Adapter). But he has no idea of the quality. Its commonly known that the second hand notebook laptop is cheaper than the brand new one. But this secondhand market is full of laptops with different qualities which makes people dazzling.
The most important step is to check the LCD screen whichs expensive and take up one third of a second-hand laptop prices. LCD screen should be few white spot, because the white spot of the LCD screen resulted from squeezing and falling down. There is a very bright white area. In the case of full-screen black, black color is also lighter. Generally, I do not recommend buying for the following reasons: 1 the performance of the screen is bad; 2, resulting in white spot is mainly due to compression, physical impact. This notebook must have potential risk. Then come to the bright spot, bad spots and dark spots. The bright spots on the screen are intolerable. After all, it is dazzling which makes users feel uncomfortable. As to the screen brightness and color uniformity, its acceptable if there is no yellow and red displaying.
As long as the LCD screen is ok, then you can release yourself. Have a look of the whole appearance, as the top cover, screen frame, care palm, keyboard, AC adapter bottom shell, all the cover, etc. Identify a number of roof renovation tips: renovated roof, most do not have LOGO. Or some parts are lack of paint so that you can see within the second layer. As for the IBM series of notebook computers, it is easier to identify. No refurbished IBM laptop lid surface coating and a certain gap between LOGO and LOGO above have a special coating. If refurbished, the LOGO and roof surface coatings has no gap, and the LOGO become very smooth and lose the protection of the coating.
For other segments, its easy to distinguish whether its damaged or not. Like my friends Compaq Presario CQ50 AC Adapter, there is not the original adapter. But it works well. That is not so important, because the laptop screen charges the price of second hand laptop.
