High Definition Audio Controller Waked Dell XPS M1710 from Sleep

[Gary J. Dikkema]

That's what command powercfg -devicequery wake_armed tells me when I run it
after the machine wakes from Sleep.

Bizarre!

Anyone else seen this?

TIA.

wake_armed tells what could start, not what did start.
powercfg -lastwake
gets you what caused the last wakeup.


device manager
system devices
high definition audio controller
power management

there is check box to allow this device to wake the computer
I have it unchecked on my Dell XPS 410

Awesome! Didn't even see the device there; mine also *had* a checkmark.

Now to see...

Thanks so much!

.... and that made NO difference either. <VBG>

the -lastwake points to the RTC.

So how does that help?

TIA.

RTC - Real Time Controller (on the motherboard)
You have set up something to run at a specified time
Vista sets the RTC to wake the computer at that time as it was going to
sleep.

Possible items that are set to wake the computer at certain times:
Scheduled software updates (Microsoft or security software for instance)
Update the TV guide in Windows Media Player
Calendar programs
Backup programs
Phone home programs (legit or malware)

One area that you can check for scheduled programs is the Task Scheduler,
not all programs that schedule themselves do so through the Task Scheduler
however.

Thanks Michael...

The laptop had this problem out of the box when it arrived.

Understand your comments below; have checked Task Scheduler as well as
Eventlog etc.

Tell me, does your laptop wake up from Sleep overnight? Do you have all of
the Dell utilities installed?

I have white boxes that I've built that do NOT have this issue. Some have
dual tuners...

Fun stuff eh! <VBG>

Thanks again!

Gary,
My laptop does not wake from sleep, but then it is XP so not really apropos.
My desktop (Vista) does wake itself up from the hibred/sleep mode to perform
various tasks. It then goes back to sleep.

It is certainly possible that the DellCrap that was preinstalled on your
computer is updating stuff or phoning home.

Waking up from sleep is a purposeful feature of Vista. However some people
hate it. There are many threads on the groups with subjects like 'laptop
wakes up' 'won't stay asleep' etc. Unfortunately those threads seem to
attract a lot of trolls and MS haters. Be carefully what advice you take
from these threads as you can end up with a damaged system.

On my Vista XPS410 desktop I only have one task in Task Scheduler that is
set to wake the computer, that is RoxioUpdater.
You can go through each task in the Task scheduler to see if any there are
set to wake the computer. You need to click on each folder in the left pane,
then if any items show in the top middle pane select them one at a time and
look in the lower middle pane Conditions Tab, under power settings is 'Wake
the computer to run this task button'

Programs CAN schedule themselves without listing in the task scheduler so
this won't find them all.
