Changing S1 to S3 suspend mode after installing XP SP2

[Jeff Barnett]

When I installed XP, the BIOS was left at its default setting - S1
suspend mode. I want to change it to S3 without reinstalling the OS. I
have no devices that should get in the way of doing this and wake on USB
devices is disabled. Is there a back door to make the switch or am I
stuck until I build a new machine or reinstall?

PS For those who don't know, XP builds its hardware layer at OS install
time and is not inclined to switch modes thereafter even if you change
the BIOS setting.

Google for "dumppo.exe", a tiny tool from Microsoft, available for
download from ftp.microsoft.com . The tool has some command line
switches, with a feature called "administrative override". Dumppo
will allow you to change to S3 suspend to RAM, now that the BIOS
setting is corrected.

Thank you for the pointer. It worked fine. The only glitch I found was
the need to create a register entry so that my USB keyboard could wake
the computer from S3. The keyboard is a Microsoft Digital Media Pro. You
would think that Microsoft drivers wouldn't get in the way of power
management.
