Windows 7 BSOD NTOSKRNL

I am using Windows 7 on a Toshiba Satellite A100 Pro, windows has been in use since release, firstime had this error 2 days in row.

POWER_DRIVER_FAILURE.
Minidump shows NTOSKRNL.EXE+D1574


This seems to happen after I have been away from laptop for some time, possibly when going either to screensaver or after in to sleep mode.

Have attached a jpg of minidump contents. Any help appreciated. Many thanks.

I'm sure a smarter guy than me will be along to help. In the mean time here is a link that sort of explains the fault. http://msdn.microsoft.com/en-us/library/ms795679.aspx
I would make sure you have all the correct drivers for your laptop. Have you done a search to see if others with that model of laptop are having issues?

Hi Pasha, Many thanks for reply, will try and read all today and then see if problem still there.

There is a member here called TorrentG who analyses minidump contents, although I've not seen him around for a few days. If you follow the instructions in this thread and then attach the files to the current thread he may be able to help.

Hi Ian,
Many thanks, have uploaded zip file after some effort as Windows 7 did not like it, done with Tugzip. Again thanks for reply.
