So are you all set at this point?

It would be more accurate to day that I am resigned to my fate.

I do not have a tester to properly check the power supply to see if it is indeed faulty. My only remaining option is to buy a new one and hope that is indeed the problem.

If it isn't the power supply then I will have to eat the cost and take the machine to a shop to get a repair estimate.

I've done a lot of reading on this subject in the past couple of days and it seems that power supply failures are very common. They look to be more common than the other potential failures, (ie: shorted motherboard, or failed video card, etc). I thjink my odds are pretty good that the power supply will be the solution.

The biggest wild card is what co$t to expect. It's an odd size power supply so I have to order from IBM rather than just pick one up at the corner computer store.

Thanks for your help and interest. It is appreciated.

weegordie,
i'm browsing this forum and noticed your entries on your ps issue with a ibm computer. I'm curious as to whether or not a new supply solved your problem. I have same problem. I have the +5v SB voltage however not sure if other voltages should be on when 1st plugged in. To me it appears that the mb needs to send a signal to the ps to turn on remaining supplies when the on button is pressed. i'm at odds as to whether that ps_on signal is missing thus a bad mb or if the supply is dead.
After I saw your forum entry was exactly what I was dealing with I had to ask how you turned out. Any help you could provide would be appreciated.

Thanks,

This was a while back so I don't remember details other than to say that ALL power supply problems I have worked on over the years have ultimately been resolved by replacing them. I do not ever remember actually fixing one. I do remember that IBM power supplies are unique, and VERY expensive, close to $200. Hope this helps. weeG
