XP sp1 : problem w/ modem & hibernation

By dirk_k_wa ·
I have a workstation running Win XP sp1 with an AOpen internal (software based) modem. The workstation is used with a dial up account.
PROBLEM: When I shut down XP and leave it in hibernation mode, any phone call results in the system coming out of hibernation.

Is there a way to prevent this unintended wake up(other than disconnecting the phone line or shutting off the power supply)? I've heard that XP sp1 has a number of problems with modems, but I haven't heard of many workarounds at this point.

Look at the properties of the modem in the device manager. You should see a Power Management tab there. Uncheck the button that says "Allow this device to bring the computer out of standby".

I should have added, that Power Management option, "Allow this device to bring the computer out of standby", doesn't have any effect on this. It surprised me, because the option appears designed to handle the exact scenario I've described.

Go into the BIOS and disable Wake on Lan & Wake on Ring.

Thank you....the BIOS configuration worked: The Power Management section in the BIOS has options for "Wake on Ring" and "allow PCI to wake". I disabled both (I don't need either to wake the workstation).....and that cured the problem. Thanks again.
