BSOD when trying to sleep or hibernate, bugcheck code 0x9F
I have had intermittent problems with getting my HP laptop to successfully enter sleep or hibernate mode. Recently the BSODs are happening much more frequently, and I can't determine what changes may have precipitated any of this.
When trying to sleep, the screen goes black, but the HDD and fans spin until a BSOD appears (many minutes later).
WhoCrashed analysis of the latest minidump
Analyisis in WinDBG gives the same results.On Thu 6/14/2012 12:53:36 AM GMT your computer crashed
crash dump file: C:\Windows\Minidump\061412-45271-01.dmp
This was probably caused by the following module: ntoskrnl.exe (nt+0x7CC40)
Bugcheck code: 0x9F (0x3, 0xFFFFFA8007B4D060, 0xFFFFF80004778748, 0xFFFFFA8007FD3B80)
Error: DRIVER_POWER_STATE_FAILURE
file path: C:\Windows\system32\ntoskrnl.exe
product: Microsoft® Windows® Operating System
company: Microsoft Corporation
description: NT Kernel & System
Bug check description: This bug check indicates that the driver is in an inconsistent or invalid power state.
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
The crash took place in the Windows kernel. Possibly this problem is caused by another driver which cannot be identified at this time
I have read about this being often caused by video or network drivers, so I have tried to update all of those. I have also tried a CHKDSK.
My machine (full system specs in my profile)
Windows 7 Professional x64 SP1 Retail
1 year old laptop
6 months since OS install - it seems like the problem has always occurred in some form, since the initial OS setup
P.S. I would love to learn more about debugging my crashes, so I appreciate any guidance on the steps I missed.
Thanks very much for your help!
