I'm having trouble turning on my HP Windows 8.1 laptop. Whenever I press the power on button the f12 and caps lock keys light up and nothing happens. I've tried doing a hard reset on the computer but it didn't work. Does anyone have any ideas on how I can fix my computer?
Those would be error codes, if POST fails before the display is tested and activated HP's will flash an error code on the caps LED. Their desktops do the same, not sure about other manufacturers.
Three grouped and repeating flashes usually mean fucked RAM, continuous flashes means BIOS corruption. How many times is it flashing?

The F12 key blinks every 5 seconds for about a minute and then stops completely. This is after pressing the power button.
If I hold down the power button both CAPS and F12 will blink together once and then stop completely. I think It might be a system board problem. Thanks anon.
Yeah, buggy CPU from the sounds. You can try pulling the CMOS and main battery and holding down the power button for 30 odd seconds to see if that brings it back.
What model are we talking about here? If it has a socketed CPU it might be worth reseating it.
