Why power fail EID 41 when sleeping after SP1

[GeneO]

If your boot device uses a SCSI miniport driver (like with my on-board 6Gb/s SATA Marvell chip), and if you have hybrid sleep mode option enabled (so that hiberbation is involved), after SP1 you are probably wondering why instead of sleeping your computer is now shutting down uncleanly with a Event ID 41 kernel-power fail, unclean shutdown of windows. See this thread:

I resolved my issue by disabling the hybrid sleep mode, but there is a hot fix available from Microsoft for this issue. I plan on trying it tonight:

A crash memory dump file is not created, or hibernation does not work, when you use a SCSIport miniport driver as the startup device driver in Windows 7 or in Windows Server 2008 R2

UPDATE: I applied the hotfix, reenabled hybrid mode, and all is well now.

Fantastic! I had roughly the same problem, two night struggling, and even removed hybrid sleep / hybernate.

Every time I attempted to hibernate, the PC switched off prematurely. The fix proposed here fixed the problem and everything is running fine.

Thanks very much!

Thanks. Worked perfectly.

For info: This issue occurred several weeks after SP1 installation. Apart from usual patch Tuesdays there was no change to the OS - so why it "just went" I'm afraid I can't say. Event ID 41 was the give away.

Thanks
