Vista SP1 breaking your hibernation?

Vista SP1 broke my hibernation, so I searched and came across this. It worked for me, so in the interest of helping someone else, here you go:

1. Run CMD.EXE as administrator

2. Run the following command: bcdedit -enum all

Look for "Resume from Hibernate" in the output from the command above(example below):

Resume from Hibernate

---------------------

identifier {3d8d3081-33ac-11dc-9a41-806e6f6e6963}

device partition=C:

path Windowssystem32winresume.exe

description Windows Vista (TM) Enterprise (recovered)

inherit {resumeloadersettings}

filedevice partition=C:

filepath hiberfil.sys

pae Yes

debugoptionenabled No

3. Once you have found it, copy the value for identifier (in this example - {3d8d3081-33ac-11dc-9a41-806e6f6e6963})

4. Run the following command: bcdedit /deletevalue {3d8d3081-33ac-11dc-9a41-806e6f6e6963} inherit

5. Test hibernation.
