If you're lucky, they'll have a compatible processor off hand (chances are they won't), but if not, they'd have to order one, which you'd have to pay for, so if it doesn't fix your problem, you're boned.
The problem is that when I power up the laptop the hard disk and fan power up but the screen stays black. Also the caps lock and number lock lights start flashing. I've tried holding down the power button for a minute, resetting the ram moduals and replacing the CMOS battery and none of it has worked so as far as I know that means the problem lies with the CPU. Am I right in my reasoning or could there be something else wrong with it that I haven't tried yet?
