This is not like the black screen I've received before on a different computer. With this black screen the power light is on, the power adapter light is on and the wireless light is on. The mouse arrow does not show. The light that SHOULD be on that lets me know the computer is loading up is not on. My keyboard light goes on when I touch a key, but the status light does not go on when I press the caps key nor the number lock key. I've tried the turning everything off and counting for a while before turning back on solution, I've tried the "Assist" key (Sony Vaio laptop), I've tried control+alt+delete, I've tried safe mode, tried F8, F10, tried windows key, etc. Nothing works. I hear something running but I don't know if it's the hard drive or the fan. I think it's the hard drive running. This is just a guess. Most of the information I used to try and solve my problem came from here, the Microsoft website, the Sony troubleshooting website, as well Youtube. I'm completely tired of trying. I truly hate to trash a computer than can be saved if it's not costly. I'd rather avoid taking it somewhere to get it fixed, which is why I am here for help. I just can't afford to get it fixed. The problem came about overnight, about 3 weeks ago. My computer was left on overnight. I woke up the next day to the black screen and it's been black ever since. Any help would be greatly appreciated. Thanks in advance.
