BSOD while laptop is inactive, 0x0000009f

MrMcMillan · 27 Oct 2016

Hi,

I'm using a Surface Book, and have been having random BSODs when the computer is asleep. Would very much appreciate help identifying the issue!

Code:

DRIVER_POWER_STATE_FAILURE (9f)
A driver has failed to complete a power IRP within a specific time.

I suspect your WiFi is turning off or reducing power while sleeping. Go into Control Panel, Power Options and set WiFi to Maximum Performance. See if that helps:

Hi Rich,

Thanks much for the quick response. Unfortunately it seems like Wireless Adapter Settings don't exist on the Surface Book under Power Options. Any thoughts?

Did you click on Change Plan Settings?

Yup. I only have one power plan .See below:

Hmmmm. Only the last dump shows the power irp problem. All the others are Bugcheck 19C

Code:

Use !analyze -v to get detailed debugging information.
BugCheck 19C, {10, ffffa30b161bc7c0, ffffa30b153af750, ffffa30b1fac8640}
Probably caused by : ntkrnlmp.exe ( nt!PopWatchdogWorker+11a )

Is it possible to overclock a Surface? I see this:

Code:

2: kd> !sysinfo cpuspeed
CPUID:        "Intel(R) Core(TM) i7-6600U CPU @ 2.60GHz"
MaxSpeed:     2600
CurrentSpeed: 2808

Which shows it being overclocked. Could be perfectly normal but just in case. If you are over clocking, set to nominal and test.

Hi Ztruker. I am not overclocking it (didn't even know it was possible!). How would that be controlled within Windows?

Ztruker · 28 Oct 2016

It would be controlled in BIOS. It may be the Surface automatically adjusts the CPU speed depending on load and usage.

Since I know nothing about the Surface I have nothing else I can think of top help at this point.
It has to have some kind of WiFi capability but it doesn't seem to have any power options for it.
