I'm new here, so hello and thanks in advance for your help.
I've had an HP Pavilion 511k for years and it hasn't given me any trouble, but over a year ago I had to go to another country and left it with a friend. Now that I'm back, he returned it but it doesn't work. He tells me he almost didn't use it, but one day he tried to turn it on and it just didn't.
Here are the specs:
I don't get anything on the screen or beeps from the computer.
There is something peculiar, when I plug the cable to the power supply, the motherboard's green led turns on (dunno what it means) and the CPU's fan starts spinning, even though I didn't push the power button on the front. Actually, when I push the button, nothing happens.
I disconnected and connected back everything (HDD, floppy, DVD burner, RAM sticks, battery) and tried booting after each change: nothing.
