HP G62 laptop powers up but no display and fan is running

A family member had a problem with their HP G62 laptop not displaying anything on the screen. I naturally thought it was a user related error until further investigating. The WIFI indicator light was showing orange, the Caps Lock light was out and the hard disk wasn't doing anything. I found the trouble shooting steps for the laptop and went through them doing the following.

  • Test the memory by removing SIMMs one at a time
  • Checking the hard disk
  • Trying an external hard disk

But nothing worked and the usual check, the Caps Lock flashing light didn't display anything then I chanced on the following post on the HP website. The key piece of information here was that I think the BIOS had become corrupted. To solve the problem I did the following.

  • Remove all peripherals from the laptop
  • Remove power supply
  • Remove battery
  • Hold down the power button for 30 seconds (to drain any power from the laptop and hard reset it)
  • Then start up the laptop while holding down the Windows and B key together

Surprisingly the screen burst into life and the machine began to rebuild/reinstall the BIOS and suddenly worked! While doing so the caps lock light flashed several times.

I hope this helps someone.
