This just happened yesterday and the machine seems to be dead.
When power on, the fan would be on for a few seconds, then off, then on. All while there is nothing on the screen.
I suspect that it is a power supply issue?
Oh, I tried to take out the old power supply, but after removing the back 4 screws, I still could not take it out. The manual does not show how to replace a power supply.
Thanks.

Greetings,
Welcome to the forum.
I am not a HP employee.
I believe there is a retention lever that must be depressed to remove the power supply. Worked on a h8-1380t which had this power supply lock mechanism.
I concur, your power supply may be in trouble.
Try a different power supply to confirm.
Regards
