Hi all, I have a compaq windows 7 Presario CQ57.

Today I was using it and I shut it down before I left. I came back and turned it on to find my caps lock blinking the power button on and my Internet button on orange? My screen is black. Can I have any advice please ASAP thanks

Hello,

Try this 1

Unplug the power cord --> Remove the battery --> Hold the power button for

60 seconds --> Connect the power supply then try to switch ON the laptop and

later put the battery back into the laptop.

Good Luck

Laptops accumulate what is called "flea" power. It often need to be drained.

If the caps lock is flashing this usually means the laptop has overheated and the graphics chip joint solder has melted. The contact between the graphics chip and the motherboard is lost resulting in a black screen (no display) I have reheated the graphics chip with a heat gun after removing the motherboard this usually reflows the solder at the joint. After letting the board cool for a few hours i rebuilt the laptop and the display worked again.This might only be a tempoarary fix and usually means installing a new motherboard and cleaning the cpu fan and renewing the thermal compound on the cpu,
