Compaq SR5000 will not power on when power button is pressed. No fans, no LEDs, no sign of life. Power supply does not have its own power switch, just a voltage switch, which is set to 115v. I switched the voltage selector back and forth just to make sure it was positively engaged.
I have tried these troubleshooting steps to no avail.
There is power at the PC end of the power cord.
There is a small green LED on the back of the power supply, no idea what it’s supposed to indicate but it is off, and starts to flash when I unplug the power cord. Per above instructions, I tried holding the power button in for 10 seconds while unplugged, then plug back in, but no dice.
The power button tests OK for continuity when pressed.
Pulling the power plug from the mobo and jumping pin 16 (“PS on”, green wire) to ground, nothing reads any voltage.
My only conclusion is that the PS is undeniably and reliably dead. Unless there is something that I’m completely overlooking.
It’s not dead. It’s pining for the fjords.
Ok, it’s dead.
Jumpering PS-ON to ground should make it start up. I am assuming that in addition to being disconnected from the motherboard all of the disk drive connectors are disconnected as well. I personally would be tempted to open it up and look for a fuse. Other than that it’s probably time to replace it.
You would be assuming correctly. I am not experienced enough to be comfortable opening it up. I have a clue but I am sure I would touch a hot cap or something.
That machine most likely uses a standard ATX power supply and is a very easy swap out for even the most timid technophobe. Basic part is available for max $30-40 at any local computer shop.
Unplug machine
remove case cover screws
remove screws holding power supply to case
Unplug all power leads from various devices in computer, take a few pictures if you think you will have trouble remembering where everything goes.
Take power supply to computer shop and say “I need one of these”
take home and plug back in.
Power on computer.
Most likely it will fire right up
Power supply failures are pretty common
Thanks. I’m thinking I’ll make a trip to Microcenter tomorrow. I have no fear of computer internals, but am not about to crack open a power supply. I built my own machine. This is a lower-end machine that my teenage son uses for homework and email.
Thanks for the help, picked up a new PS for $14, popped it in, back in business.
