Task scheduler and sleep mode - Sleeps too soon


A

Adam

If I create a scheduled task in Vista, set to wake the computer from sleep
mode, Vista wakes correctly, but goes back into sleep mode before the task
is finished.

I've seen a couple of posts here mentioning similar problems, and I'm
wondering if Microsoft are aware of the problem. I have the same problem on
two different PCs both running Ultimate (one upgraded from XP Pro, one with
Vista pre-installed).

The PC wakes up correctly at the time the task is due, starts to run the
task, but then goes to sleep after 1 or 2 minutes, usually before the task
has ended. When it next comes out of sleep (for whatever reason) the task
resumes. I've tried changing my power settings to put the PC to sleep after
various time periods from 15 minutes to 2 hours, but get the same effect.

It appears to happen regardless of the user the task is set to run under,
and whether the task is set to run in "Vista mode" or "2000/XP mode".

I've even tried to manually put the PC into High Performance mode (using
powercfg) as the first step in the task (the idea being to then put it back
into my standard power mode once it's finished), but it still goes to sleep
within a couple of minutes and before the task ends. Doing a powercfg -l
shows that the PC is in High Performance mode during the task (which, of
course, is configured not to sleep).

This is causing me real problems as my nightly backups aren't completing!

Any ideas?

Thanks.

I have worked with MS support on this for 2-3 weeks. Here is the
latest thing they told me:

I can understand the inconvenience that this issue causes. Actually,
this issue can also be reproduced on test machines at our technical
support site. Therefore, we can confirm that the issue is not system
specific but is related to the programs and codes. I have immediately
forwarded this issue to the relevant team for further investigation.
Please be assured that our developers will look into this issue and
find a permanent solution. Your patience and understanding on this is
greatly appreciated.

So at least on some level they are aware of it. I asked if there was
any way I could track the progress of the issue, but was told no, that
I would be informed when a fix was available, but there was otherwise
no way for me to stay up to date on the status of the investigation.
So I am hopeful for a fix someday but am not holding my breath.
