Question about Compaq (480082-001) ( 480082-001 ) Power Supply
Recently the computer will suddenly and randomly shut down, then restart and continue to act this way, cycling on and off. After removing plug from wall and waiting we can restart the computer but soon the same problem will occur. Suspected heat and cleaned all dirt and dust out. Checked cpu fan and PS fan. Played additinal fan on PS and ran all day. Closed up computer and after several hours the problem started again. Suspect PS but not sure. Does anyone have similar problem?
You need a new power switch. I am currently working on a S4020WM with the same problem. I cut one wire to the power switch, then used a paper clip to make a jumper to start the machine. It has run fine since then. The only trouble I am having is finding a replacement switch.

Same problem here.. power switch shorting. Either replace it, rig one up, or unplug it from the mother board after startup!

Yes, the power supply fan is either slowing down and allowing supply circuit to heat to a point where a thermal detector detects a shutdown condition, or the supply fan may be turning off. I had similar problem and solution was a new power supply fan.
