Have you resolved your powerup problem after using the new power supply?
I have a similar problem occur with a 900 where the connector was loose
but when using a new supply the computer will not powerup. suspect 5vdc
supply is gone.

Sounds like the jack on the motherboard is loose to me. Most of them can
be repaired, but it isn't all that easy for most people. You have to be
good at soldering for one.

Sounds like the Powerjack needs replacing to me too.
You can find Service Manuals, A Decent Tutorial Video DVD, the guy also
does the repair very cheap, and you can find lots of hints and tips on
those pages.
He also is a good supplier of almost every power Jack available.

Sorry for resurecting an old thread, but i am attempting to fix a computer with this same problem. I checked the motherboard and there is no sign that there is weak solder point or loose. The power jack which was mentioned is connected to the motherboard through red and white wires that connect to the motherboard. So will changing the power jack do anything? is there a way another way to see why it isn't working?
