You can try that generic reset first noted in the CNET Laptop Troubleshooting Forum. While you are there you discover there are very few parts to a laptop. In a shop you swap out the board or display and it's usually fixed.
I have this dell inspiron 1526, windows vista that was working good but now it won't turn on. I can hear the Hdd turning but nothing shows up on the screen. Is this fixable?
