Compaq Presario 5660

[dangermouse]

I have a friend who has a Compaq Presario 5660. He erased the hard drive and reinstalled Windows on it. Everything went fine with the Win98 install. He installed Windows 98 Second Edition. After the machine restarted a few times he shut it off.

The next morning (without changing anything at all) he went to turn the machine on. It would not turn on. He's tried everything and still the machine won't power up.

Does anyone know what's going on?

Hi dangermouse,

This is usually caused by two possibilities.

The ATX manual switch has been switched off. Sometimes people
grab hold of their towers to move them and accidentally push the
switch in the back of the tower to off.

The power supply has failed and needs to be replaced.

I fixed the 'powering on' problem. It was a cable from the power switch to the motherboard...it wasn't in tight.

Second problem is:

The power button. I turn the computer off. And then it won't turn on unless I:

- unplug the power cable
- switch off the power supply on/off switch
- leave the power cable unplugged for 30 seconds

If I do those 3 things it'll turn on for me.

What's going on?

It sounds like the power supply needs to be changed.

Hi, definately sounds like PSU

But I imagine the power supply units are proprietry to compaq.

I would look at the compaq site for info peculiar to the problem you are having.
The compaq people may have info relating to this problem.

dangermouse,

mike is correct in saying that the Power supply in COMPAQs are proprietary. The only reason I know this is because when I was designing deskpro's for COMPAQ we had to have a different PSU for every flavor of deskpro we designed. It has something to do with the way COMPAQ configures their pinouts. It sucks, but you will need to contact COMPAQ to get a replacement for it.
