Windows 7: System wakes up on its own (hp tm2)

23 Mar 2010   #11

Windows 7 Ultimate (64 Bit)


After sleeping two nights without problems (on external power), my laptop now woke up while being on battery.
I will try again, being on battery. Only problem: My battery won't last till next morning, so I won't be able to run powercfg -lastwake before it sleeps again. Does anybody know weather the event log provides exactly the same information? (I'm sure it logs something about the waking event, but I don't know how many details it logs...)

Thank you for your help,
Felix Freiberger

Here's another idea:
Download, install, and run as administrator Autoruns.

Go to the Scheduled Tasks tab (not sure about the name but you've got the idea).
uncheck as many things as you dare (have no fear- you can always go back and checkmark them again)

Problem solved?


after sleeping another night - on battery, with the setting "allow timers to wake the computer" on battery enabled - I think that my problem is solved...

Thank you all for your help!

Unluckily, I'm not sure what exactly caused the problem. I can just recommend looking around in Device Manager, even if "powercfg -devicequery wake_armed" lists nothing - "powercfg -devicequery wake_from_any" might give a few devices worth looking at.

[How can I mark this thread as solved? If just moderators can, please...]

today, my laptop woke up again automatically - but I think I found the culprit. Luckily, BitLocker delayed the boot, and after booting manually, Windows Media Center instantly started updating the TV data. In the planned tasks, I found something interesting:

If someone else has the same problem - check the planned tasks for this one!

My recent install of Windows 7 Home Premium 64-bit has been great except for one small problem. It wakes itself up every night around 9:30pm. I looked in the event viewer and found that the system either updates the time from the internet server or updates Media Center. Is there any workaround...
