Hi all,

I have a Compaq computer loaded with 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!

Thank you
Hello,
  • Unplug the power cord --> Remove the battery --> Hold the power button for 60 seconds
  • Connect the power supply
  • 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,
