power down mechanism

[Guest]

When I turn off my computer through Windows XP it logs off, saves settings,
and shuts down Windows. Then it physically powers-off my computer.

This same computer also has XP 64 as a second OS.* It behaves the same way
as my vanilla OS on shutdown provided I stay on for an extended period of
time. But if I quit after 10-15 min, the physical power-off fails to occur.

How does the power off occur? Is it a service that may not yet be started?

*I did hunt in earnest for a 64 bit discussionbut failed. Point me in the
right direction if I screwed-up in posting here.

The power off is a feature of the BIOS. Not sure why the 64bit is acting this way?

If you do want to post to a 64bit group here is the link, you will need to use the Newsreader function in Outlook Express, for some reason the 64bit group has not been added to the web based groups?

Clicking this link will open Outlook Express and display the 64bit newsgroup. (If OE is your default email program)

I don't know about 64 bit, but the power down action is initiated by
shutdown.exe, an XP program wiht several flags possible for other variations
such as REstart, etc..
The BIOS only gets into it where the decision to actually turn power off
or put up the "It's safe to turn off the computer" message, etc. comes into
play.

Shutdown.exe is located at C:\WINDOWS\system32\shutdown.exe
in XP Pro (and home). I'd start by seeing where the compatible program is
in the 64 bit version; maybe it's corrupted.

Dunno if this helps, but ...

Was talking about the power off of the computer, not Windows. This has to be handled by the BIOS since Windows is gone at that point.

Understood; I just thought it was relevant to point out that the process is
started in windows, which makes the call to bring windows down properly
before it's handed off to the BIOS for the final action object. Otherwise
people might think it's a function of the BIOS only, which it isn't.
