System wakes up on its own (hp tm2)

Hi,

I have a problem with my hp TouchSmart tm2-1090eg, running Windows 7 Ultimate (64 Bit).

My laptop wakes up at night at random times. Usually, I hibernate my laptop at night, but at the morning, my laptop is often running and draining battery.

Disabling the "allow timers to wake the computer" (German: "Zeitgeber zur Aktivierung zulassen")-setting in power options solves the problem, but, of course, disables all wake timers. (I want to use the timers, i.e. for Windows Media Center).

Therefore, I think that my problem is not a hardware or driver issue, but a software issue.

There's only one problem: I have no idea what software causes this. I thought I could catch it with "powercfg -waketimers", but I only get
C:\Windows\system32>powercfg -waketimers
Im System sind keine Aktivierungszeitgeber aktiv.
(translation: "There are no active wake timers.")


Does anyone have an idea what could cause this problem?

Thank you in advance,
Felix Freiberger

Felix,
Have you had an opportunity to investigate some of the other PowerCfg options?

Windows 7 offers many. Try PowerCfg /?

Especially of interest to you might be:
PowerCfg -lastwake

Hi,

@karlsnooks
I will try to have a look at the lastwake-option the next time it happens. Until now, I only checked the Event Log, which didn't help me much .
By the way: Does BitLocker prevent Windows from getting the wake source or does it pass that information to Windows? (Of course, I will keep my BitLocker-USB-Stick plugged into the device so it can boot up normally.)

@Bare Foot Kid
I already had a look at it.
BIOS: I see no possibility to configure anything related to sleep modes here.
wake_armed: Exits without listing anything. (Should be OK?)
device manager: I found no device which is configured to wake the computer. (Although I checked only the "usual suspects")
screen saver: The problem also exists with "none" as a screen saver.
startup programs: I did not try disabling them, but as there are no wake_timers set, this shouldn't be a problem, is it?
system restore: the problem existed since I bought my laptop.

additionally, I did a wake_from_any, which gave me:
Apple iPhone
UMBusenumerator
USB-Root-Hub
USB-Root-Hub (001)
Intel(R) ICH9-Familie USB2 erweiterter Hostcontroller - 293A
USB-Root-Hub (005)

Intel(R) ICH9-Familie USB universeller Hostcontroller - 2935
Apple Mobile Device USB Driver (004)
UMBusenumerator (002)
Intel(R) WiFi Link 1000 BGN

Thank you for you answers!

Hi,

@Bare Foot Kid: What do you mean with "in the startup file"? I looked in msconfig, but didn't find it here.

I'm going to bed now, I will:

• hibernate my laptop
• let the power plugged in (if the power is plugged in, the "allow timers to wake the computer" is on)
• plug my BitLocker USB-Stick

I have configured Windows to stay on if the device is running on external power, so it should wake at night and stay on until next morning, so I can use "lastwake".

I will post again tomorrow.

Thank you for your help,
Felix Freiberger

My two cents.

Similar to others, software dialing out.

Check Microsoft Security Essentials for one(if you run it) - it always defaults to check for updates at 2 or 4am GMT for some odd reason (from what I remember!)

If it isn't software, disable any USB devices one by one to find the culprit.

Hi,

my testing results:
None, my system didn't wake up. I have no idea whether I have fixed the problem while dabbling with the settings today, or whether I was just lucky.

After waking my device manually, the activation source is unknown, powercfg says
C:\Windows\system32>powercfg lastwake
Aktivierungsverlaufsanzahl - 1
Aktivierungsverlauf [0]
Aktivierungsquellenanzahl - 0
Is this normal for a manual wake or do I have more problems here?

@Bare Foot Kid:
The problem with you idea: The wakeup intervals seem to be quite random, between midnight and seven o'clock in the morning. And, shouldn't the "waketimers"-option be able to list such programs?

@neo101: No, no security essentials.
No device listed with wake_armed, and as it's a laptop, there are no USB devices plugged in permanently.

I will try again next night...
