Question about Compaq Computers & Internet
Dead PC, PC fans totally dead
that most times means PSU dead, or shorted modules inside PC> (im sure the power switch wire, to the mobo did not fall off) and the green LED on back of PSU is glowing green , (per manual HP ) means AC power side is good.
SR1200 series desktop made in fact in the Compaq plant in Texas.
2004 newest 2002, oldest.
if the coin cell is that old, it is bad.
none ever last that long; 14 years to 16year old batteries are no good. but a DMM check will not lie to you. 2.9v min, lower bad.
If both fans are dead , the PSU is bad.
in some cases, (no pun) we open the case
power off, (ac cord pulled)
push power on to discharge all caps in the PC,
normally one sees the CPU fan spin for 1 seconded and die. (but that is good PC yours is not)
we remove all power wires from the PSU from it
to HDD, to CD, drives, and to floppy 4 pin power
we do that because shorted devices, cause all PSU to shut down. even in 1/2 of second or LESS.
by design (ATX spec) this prevents fire, in the case/psu.
plug in PC, AC and push power, do fans run now, both must run , not just one fan.
power off again, ac line pulled, push power button again, to discharge things,
The once all those pig tails from PSU to THINGS are pulled , but not your MAIN 20 pin connector to mobo
we do what, we remove ram and test each stick 1 by one.
doing same tests, AC line pulled. remove RAM.
but 1 stick reseat it, and test for power on again.
if you have the original DDR memory sticks test them 1 by 1, each. ok>? they can short too.

Pull the battery out and then plug it in and see if it starts. someimes the batteries short out and the computer will not start that is if it is a laptop

Testimonial: "It's actually a desktop. Would taking the little backup battery out be the same, or do you mean the large battery on a laptop?"

Make sure that the power button is conected to the right prongs on the mother board. On the writing next to the prongs it should say power.

SOURCE: Won't power up!
I would say yes, the power supply needs to be replaced. It is a cheap and easy fix.
One thing to check would be the capasitors around the CPU. If any are corroded or bulging then the motherboard will need to be replaced.

This is an easy fix so here you go nice and simple:
Problem: Your motherboard circuit has been cut.
Causes: Power disconnected during operation. Power outage or short in the surge protector.
Symptoms: Flashing green light on both motherboard and power supply. System will not power on.
Step 1: Ensure that both the power supply and the motherboard lights are flashing green, not solid or off.
Step 2: While the power is on, disconnect the power supply from the motherboard. This connection is the largest of the connections and should be listed as the 'P1' or 'Primary' power connection.
Step 3: Wait until the green light on the motherboard stops flashing and check to ensure that the green light on the power supply is now solid. If it is not solid, disconnect the power to the power supply and wait until the light turns off completely. Then reconnect, it should be solid now.
Step 4: While the power is on, reconnect the P1 connection to the motherboard and you should now see that the light on the motherboard is solid.
Step 5: Power on your PC. The problem should not persist.
Warnings: If the power supply light remains flashing after you have restored power to it while it is disconnected from the motherboard, it may be a system failure in the power supply itself requiring replacement. Always be careful when working with an active or live power machine.
I hope this helped! Good luck!
