You find changing the mainboard is often the cure. I am not finding any shops that fix mainboards anymore.
I have an HP Presario V5000, running windows XP home edition. It shows no signs of life what so ever. I have bought a new power supply and battery for it just the other day. I hit the power button and nothing not even a light or fans running. A light on the power supply is green so i know it's working. I have tried holding the power button down for one minute and then pluging it back in. Nothing happens. PLease any advise?
