Windows 7 Switching Off

Hi all,

Has anyone been experiencing any power issues with Win 7 in the last 7-10 days. I'm leaning to it being an MS update, but haven't been able to find anything concrete.

This is happening across multiple sites, different PC hardware vendors, different DC's. Some sites only 1 client PC effected other sites multiple PC's. Typically, its affecting the senior management PC's that are generally left on for remote access purposes.

On some PC's they've been set on Eco mode in the power configs, we've switched them back to high performance and made sure no other settings are set to sleep, hibernate, or switch off HDD / NIC etc.

Did you already have a look at the Windows Application and System Logs (run eventvwr) for any useful and new Warning/Error entries?

Hi Strivoli, yes have dug through the event list, no errors or warnings, just info entries. I've been looking at some affected PC's this morning, and last event log for application is (8224) VSS shutting down due to idle time out at 30 mins after the person logged off from PC and went home, then the next entry is this morning for (4101) a win logon.

For System events, same time frame as application log:
ID 7036 - several, referencing VSS and Shadow copy going to stopped state and Windows Module Installer entering running state, then ID 1 for Kernel-General referencing time change, then ID 42 entering sleep. Next entry is at 'power on' by user same time as winlogon event for Application.

Checked Power settings, back in eco mode again. but sleep mode set to never.

Is there any GPO ruling the power? What does RSoP or GPRESULT report?

The sites we manage dont really require GPO's, standard Default Domain policy usually left in place. Only one thing odd after running GPresult /User %username% /V and thats domain type shows 2000 although AD is running in Server 2008 at Domain and Forest level.

I would make sure Java is up to date or take it off if they don't need it.  I only have one customer having that issue and they are always on the internet when it happens.  Maybe make sure flash is up to date.

They are on a two month old system with WIndows 7.  It ran fine for about 6 weeks then started doing this.

Also if it is doing it while they are using it then try spaying the chair and carpet with some static guard.  I have had that help also.

Still not got to the bottom of what has caused the PC's to randomly and gradually start going into switch off / low power when the power profile is set as high performance and no active GPO's, and no other power settings controlled from the SBS (where applicable).

After some further digging on other forums, we ruled out GPO's and cant nail down any specific updates.

So far the fix is holding. Log on as either local or domain admin set power profile as high performance and apply. Tweak settings on HDD to never switch off, and also change sleep settings to never, no hibernate and no hybrid sleep.

We also found that on some PC's we'd need to run powercfg.exe /hibernate off from an admin cmd prompt.
