Got blue screen - what caused it?

Hi guys ive got a notebook with this spec, only had it a few weeks!

Dell XPS 15
Intel i7
4GB RAM

Only had it once but I am a bit worried :S

here is message...

A problem has been detected and Windows has been shut down to prevent damage
to your computer.

The problem seems to be caused by the following file: ntoskrnl.exe

DRIVER_POWER_STATE_FAILURE

If this is the first time you've seen this stop error screen,
restart your computer. If this screen appears again, follow
these steps:

Check to make sure any new hardware or software is properly installed.
If this is a new installation, ask your hardware or software manufacturer
for any Windows updates you might need.

If problems continue, disable or remove any newly installed hardware
or software. Disable BIOS memory options such as caching or shadowing.
If you need to use safe mode to remove or disable components, restart
your computer, press F8 to select Advanced Startup Options, and then
select Safe Mode.

ALso just noticed that it says power state failure, i did have the laptop shut so it was sleeping i dont know if that changes anything...

Its only happened once had laptop on over an hour after with no problems should I be worried? Also had it sleeping for half an hour with a successful awakening....

Any advice would be greatly appreciated!

Thanks
Ash

 

Got Google? Bug Check 0x9F: DRIVER_POWER_STATE_FAILURE

 

Hi thnanks ive read through it but still dont seem to see what caused it or if it needs to be fixed?

Ive been on for about 3 hours now surfing etc and nothings happened is it anything to worry about?

Thanks for the link i did do a lot of searching but only found examples of windows XP computers and i only searched the .exe not the specific codes, sorry about that.

Thanks
Ash

 

Googling ntoskrnl.exe brings up software problems. If it happens again I would backup your data and do a system image restore.

NTOSKRNL.EXE is missing or corrupt.

Cause
Keyboard issue
Miscellaneous corruption
Corrupt boot.ini file.
Missing boot.ini file.
Missing or corrupt ntoskrnl.exe file.
Windows NT installed on a partition bigger then 7.8GB
Corrupted hard disk drive or severely corrupted Windows.

 

Thanks for the reply, it hasnt happened again ive had laptop on for hours doing photoshop and browsing etc...

Just was a bit worries as Ive only just got it!

So do i do the recover console steps on that link to restore the .exe if it happens again?

Thanks again,
Ash
