A laptop malfunctioning can be quite stressful. Portable computers are more difficult to disassemble than PCs and users have a harder time trying to figure out where the problem could be. Replacing something is way more complicated. If there are problems with images, one can assume that the whole laptop will have to be replaced – or at least the repair will be costly.
Laptops have become more powerful and increasingly cheaper (a study by USA Today showed a comprehensive list of milestone PCs and laptops have reached since the seventies), but surely you would prefer a quick fix rather than a whole new investment. Let alone the data you might lose. Check the three most frequent issues regarding laptop functioning. Each one of them will be detailed in other articles on this site.
When there’s no image, it’s not obvious where the problem comes from, but it’s not difficult to make a quick diagnose. If the power is supplied correctly and the LED is on, and if you don’t see anything broken, maybe a lack of RAM is the problem.
