My friend has an HP Pavilion 7940, 1GHZ P3, 128MB SDRAM running Win 2000 ME. It seems the computer shuts down intermittently. When I viewed the computer the green "on" light in the back of the computer was off. I unplugged the cord and then plugged it back in. Immediately the green light on the power supply registered "on" and I was able to start the computer.
Why would the green light to the power supply be off? Is there a thermally activated switch which shuts down the computer if the power supply overheats? To properly reset the power supply, my impression is we needed to unplug it and then plug it back in? Is this correct? And the reset functionality is within the power supply itself and not the motherboard, correct?
Comments / info would be appreciated. Thx.
