Dead computer

[Dubitout]

Power is not working, and the computer seems dead, but the green light is on. Can someone assist me with this.

Sorry, but with your PC not even starting, there is nothing we can do -- as we could only provide links to diagnostics, and if your PC will not start, it could not run those.

The green LED means there is power the motherboard -- but the lack of any fan noise and the lack of any other lights or screen display indicates serious possible hardware failures.

You would need to get it examined to determine why it will not run.

For repair estimates, you would need to contact an HP Repair or Service Center.

If you live in the U.S., here is a link to the HP Service Repair Centers:

Good Luck
