I have a Lenovo Thinkpad T440s laptop. The laptop intermittently throws BSOD or simply restarting without a blue screen, or on occasion the laptop appears to restart while in sleep mode. Each time the System event log indicates a source of Kernel-power Event ID 41. Bugcheck code is 0x9F (0x3, 0xFFFFE001D41B18C0, 0xFFFFD000D4793960, 0xFFFFE001DB4B42C0)
These events occur up to several times a day and in many instances occurs while the PC is not actively being worked on. It is not related to running a particular application (at least not in the foreground processes). I’ve attached the DM Log file.
I've searched the Event Logs and don't see any obvious errors or warnings prior to the BSOD/reboot. I did run a utility called "WhoCrashed" and it is inconclusive as to any particular process or driver responsible. It does say that the error was caused by ntoskrnl.exe (nt+0x150CA0). Error is Driver Power State Failure. It also notes that the problem is possibly "caused by another driver that cannot be identified at this time". In the WhoCrashed report it suggests that the Intel WiFi link driver netwbw02.sys has been causing crashes on the computer, but I have the current Intel WiFi and Bluetooth drivers installed for the Intel AC7260 Dual Band Wireless. I've also reinstalled the AC7260 driver software in case I had corrupted driver., The reboot problem still occurs after updatingView attachment 61763.
Any help you can provide on this would be greatly appreciated.
