I have a user running Windows 98SE on an I-will motherboard and Athlon 1.4ghz processor. His PC is not going into sleep mode (standy or suspend) after a certain amount of minutes set in the power control panel. We have enabled power management features in the BIOS as well as Windows 98, but no luck. The only thing I can think of is that he is connected to a APC UPS via serial port which is constantly polling the UPS for power fluctuation. And he's running an external USB ethernet network devicewhich may be preventing him from going to sleep. Any thoughts or experience on this would be appreciated.

I think your own assessment is correct. The PC will not sleep if there is any activity on it - and anything that polls is certainly going to stop the suspend function.

Obviously if you wanted to verify it, you'd need to uninstall the network cardand UPS - and check there wasn't other background software periodically waking up...

Can you manually suspend the machine?

Cheers,
Tim.

your correct about the activity but i doubt it is a ups. It is more likely then not a screensaver or background application running constantly. try removing all tsr's from memory then letting it go.

This didn't work. Closing everything from the task list and letting it go didn't work. Thanks for the suggestions though.

Assuming it's hardware related, figure out what IRQ the serial ports and USB are using, then go into the BIOS, and tell it not to wake on those events.

We also tried this and it seemed to work half-way as well. We switched Power supply and it seemed to be working better now. Thanks for the help.

98SE has a history of not shutting down correctly, rebooting when the shut down option is chosen, etc. MS has a Q# detailing a list of possible problems. The Q offers about 15 different troubleshooting options. Also, if you have downloaded KaZaA or Morpheus, they are known to cause shut down/suspend problems.
