Unable to enable hibernation

[Adam Hall]

I am unable to enable the hibernate mode on my laptop. If I attempt to, the
following message appears:

Power policy manager unable to reserve hibernate file.
The process cannot access the file because it is being used by another
process.

I initially thought this was maybe due to some software installed, so I
stopped all but the very core services and unloaded everything running that
I could and still no luck.

Anyone got any idea?

Laptop specs:

HP nc8000
Pentium M 1.6 GHz
1GB RAM (is that a problem?)
Windows XP SP1 with all windows updates

Thanks

Perhaps the Hiberfil.Sys file is corrupted. Go to Control Panel,
Power Applet, Hibernate (Tab), uncheck Hibernate option.
Reboot and then re-enable, which should recreate the file.

Sorry, I may have been unclear.

I cannot check the option to enable the hibernation. If I check the box,
then click Apply or OK, I get the error message.

I have tried using several admin accounts, both local and domain, the
permissions in the root of C are OK, there is no existing hiberfil.sys file.

Weird.

O.K, I follow it now. Some notebooks have a dedicated partition for
handling Hibernation states which is controlled by BIOS. You didn't
mention Brand/Model #, but this type of Hibernation isn't really used
that much anymore. This could also be some type of application that
the OEM placed on the computer to take control of Power states.
If the notebook is ACPI compliant, then XP should be able to use
Hibernation. You should check Add/Remove in Control Panel & see
if any listings appear related to Power. It might be as simple as locating
the 3rd party app and uninstalling it.

Thank you very much. While I didn't have that exact problem, it did relate
to atapi.sys

In the end I uninstalled daemon-tools, enabled hibernation, then reinstalled
and all OK.
