Here's a really weird one: Windows 7 Pro, 32-bit. Pretty new install, it is only about 3 months old. Joined to AD 2008. When the user is in the office and connected (either wired or wireless) to our main network, the computer will shutdown normally. However, ANYWHERE else he is connected (at home, coffee shop) wired or wireless, the computer will hang upon shutdown, and after a few hours will eventually produce a BSOD stating drive state power issue. Additionally, if the computer goes to sleep and the user presses the power button, they also get a BSOD. What I've done so far: All windows updates are installed and current All driver updates are current, direct from HP Computer was shipped in for service, burn in test revealed all hardware was OK Replaced hard drive even though it indicated it was good. So it has a brand new hard drive (I imaged the old drive) Windows logs are clean prior to and after a BSOD Had the user leave mobile VPN connected from home and then shutdown with VPN still running I just can't wrap my head around why it works perfectly here in the office, but has problems when it cannot see our network. I was wondering if resetting the computer account might work. Any other ideas? This one really has be baffled - never seen anything like it. Thanks- Brad

Hi Brad, What is your computer model? Please upload the minidump from C:\Windows\Minidump\Minidump.dmp to SkyDrive. First, update the BIOS from the manufacture site. Then make sure you login with the local user account. Also, change a different power plan to check the result. Since it is a client PC, it might run script, sync files or load drivers from the server when shutting down.

Computer model is HP Elitebook 8730w. BIOS is updated, all firmware and drivers are up to date. I have already modified the power plan a few weeks ago. DMP files (3 recent ones) are here: http://cid-40b364311ee95077.skydrive.live.com/redir.aspx?resid=40B364311EE95077!149 Thanks!!!! -Brad

Did you have a chance to look over the dmp files? This problem is still occuring.... -Brad

Hi Brad, From the dump file, I find error message DRIVER_POWER_STATE_FAILURE with 0x0000009f. http://msdn.microsoft.com/en-us/library/ff559329(v=vs.85).aspx The root cause is Wdf01000.sys. Wdf01000.sys is located in the folder C:\Windows\System32\drivers. Known file sizes on Windows 7 are 434K. Check where is the WDF Dynamic process located. Also let me know If you have installed any software recently before the issue occurring? If so, try the System Restore first. Also perform a Clean Boot to check the issue. However, if the issue persists, it seems the Wdf01000.sys is corrupted. I suggest trying System File Checker to repair it. http://support.microsoft.com/kb/929833/en-us Regards, Niki Please remember to click "Mark as Answer" on the post that helps you, and to click "Unmark as Answer" if a marked post does not actually answer your question.

system file checker did not find any errors. The Wdf01000.sys file is where it should be, and is the correct size. I was unable to run System Restore because for some reason it is completely disabled. I'm also seeing some other strange stuff on this machine and wondering if it might be a virus or something. Running a full scan now. Should I perhaps try a Repair install with the Windows 7 Install CD? -Brad

Hi Brad, Please boot in Safe Mode with networking to scan the computer. Malicious Software Removal Tool http://www.microsoft.com/security/malwareremove/default.mspx Online Safety Scanner http://onecare.live.com/site/en-us/default.htm Malwarebytes free version http://www.malwarebytes.org/ If the computer is clean, I suggest replacing the problematic file from the installation disk.

The machine currently has no viruses/malware - but the antivirus system shows it previously had a large number of viruses. Further investigation shows that there are a number of other issues: Not processing and applying group policies Computer Manager will not launch 3rd Party applications will not open, even though they appear to be running in the Task Manager My conclusion is that while there are no current viruses that at some point a virus was able to cause significant damage prior to being cleaned out. I will reinstall Windows at this time because trying to fix all of these problems will take longer than a rebuild. Thanks for all your help! -Brad
