Unplug the power, if a laptop remove the battery. Press and hold the power button for 60 seconds, release, apply power and try again.
Hi. First, I'm no pc expert but I'm not afraid to tamper! Now, the power went out in 2 counties & the pc won't come back on. I have a green solid light beneath the power cord on the back. I tried unhooking everything from the motherboard and all the drives, even took out memory. Nothing changed. Socket works & also tried a different cord. Is it my mobo? Google thinks the power supply is ok because of the steady light. No fans, no beeps, nothing happens when I click to turn it on. Any other suggestions before I purchase a new pc??? It is an HP Slimline 3700 using Vista.
