The auto-sleep option only works 50% of the time for me. Manually pressing
the sleep button always works.

Why does the auto-sleep function often fail?

Perhaps an application that is, in effect, telling the PC that it is
being used is suspect.
What's running?

A couple of possibilities. Auto-sleep is supposed to kick in during periods
of inactivity. Sometimes, there might be things going on in the background
that cause it to think the system is not inactive. If you are connected to
a broadband connection, that can be picked up as possible network activity.
One thing that might help avoid that is if your computer BIOS has a wake on
lan function, try turning it off.

When the system boots, the first screen usually has an instruction to hit a
specified key if you want to enter setup, that gets you into the BIOS. Then
you need to navigate through the various screens to see if your system has a
wake on lan function and see if it is enabled. If yes, disable it, save and
exit. ***Note, this may not entirely solve the problem as some background
activity might still be read as activity as opposed to inactivity.

Another possibility is some systems have the ability boot by simply pressing
a key on the keyboard. Small motion, any small vibration, might transmit
from the mouse that again, might make it appear as though the system is
active. Again, same approach as above, I believe this function can also be
turned off in the BIOS. And, again, not perfect but it may up the
percentage of times the function works for you.

Also, be sure you have noting set to run in the background. Other
possibilities are items that might automatically check for updates including
Windows auto update function. If you have an always on connection, those
things will check as will anything set to auto check for new e-mail.

I think I've noticed screen savers seem to prevent, or greatly delay idling
to sleep. Not done any conclusive studies yet, but may be I will. 8-)

Only IE7, Messenger and Outlook running. Just shut all apps down and tried
again... Now it turns off.

Why would these apps stop it from auto-sleeping?

I have just turned the apps back on and auto-sleep is working fine
again....What's up? Why soes it work sometimeas and not others?

Should I have hybrid sleep on or off?

If the problem persists, try toggling hybrid sleep to the other mode, as
a test.

Because messenger and Outlook check for messages and random intervals. Even
with auto send and receive turned off, with IE open, random packets can be
transmitted and this would register as system activity. That fact it didn't
happen when you closed and reopened the apps was coincidental as the sleep
function may have been set to start in a period when those applications were
still idle.

If you tried using the sleep button enough times, it will fail occasionally
also. Hp tech support has no answer. Bug report to Vista Developemnt group
has no response.
