Hi, I have the same HP Notebook dv6t-2000, quad and the same problem (driver_power_state_failure). The notebook gets into BSoD in 7-10 min if I try to restart or place it in sleep. (Here is the event message, the same as a case posted above Additional information about the problem: BCCode: 1000009f BCP1: 0000000000000004 BCP2: 0000000000000258 BCP3: FFFFFA8003D0EB60 BCP4: FFFFF80000B9C510 OS Version: 6_1_7600 Service Pack: 0_0 Product: 768_1 ). This appears to start to happen after I ran my Windows update a week ago. I tried to read the mini dump file using the debug tool. But it does not provide enough info ********************************************************************* * Symbols can not be loaded because symbol path is not initialized. * * * * The Symbol Path can be set by: * * using the _NT_SYMBOL_PATH environment variable. * * using the -y <symbol_path> argument when starting the debugger. * * using .sympath and .sympath+ * ********************************************************************* Probably caused by : ntoskrnl.exe ( nt+77dda ) Can I upload the dump file for some to take a look? Thanks. Li

Since Windows system uses separated user mode and kernel mode memory space, stop errors are usually caused by kernel portion components, such as a hardware device, third-party drivers, backup software or anti-virus services (buggy services). Please refer to the following steps to troubleshoot the issue. 1. Boot the computer in Clean Boot for a test. 2. Temporarily disable all unnecessary hardware devices in Device Manager, such as Modem, sound card or external device. For detail steps, we can refer to the link below: Device Clean Boot 3. Run antivirus program and perform a full scanning. If the issue persists, please upload the minidump file (%systemroot%\minidump) to SkyDrive ( www.skydrive.live.com ), then share the link to us.MCSE, MCSA, MCDST [If this post helps to resolve your issue, please click the "Mark as Answer" or "Helpful" button at the top of this message.
