that is probably the issue then.
Alcohol 120%, which
must be completely uninstalled before hibernation can be activated.
After activation, Alcohol can be reinstalled.
Just in case Alcohol does not fully uninstall, and the problem
persists, the following, which was written for Daemon-Tools but also
applies to Alcohol, will fix it.
1. Open device manager (SCSI
/RAID Controllers section) and delete SCSI
controller with name corresponding with name of Daemon driver
(miniport driver name). If you have problems doing it (e.g. system
crashes) then start from step 3 (skip steps 1 and 2).
2. Open device manager (System devices section) and delete device with
driver corresponding with Daemon driver (bus driver name). In current
versions of Daemon Tools it is 'PnP BIOS Extension' but most likely it
may change in next versions. Again, if you have some problems doing it,
skip this step
3. Find Daemon driver files in Windows\System32\Drivers folder
(in Win95/98/ME also check Windows\System\IOSUBSYS folder).
Make sure your system is configured to display system files
(ControlPanel->Tools->FolderOptions->View) in order you can see them.
Delete Daemon driver files.
default v3.46 driver file names are d346bus.sys and d346prt.sys
default v3.47 driver file names are d347bus.sys and d347prt.sys
4. In WinNT/2000/XP/2003 open registry editor and check
es for entries with same names as Daemon driver files. Delete these
5. Reboot your system. If you executed steps 1 and 2 then you don't
need to do anything anymore. Otherwise proceed to next step.
6. Go to device manager - you may see some device with yellow mark.
This is most likely Daemon device which cannot start because it's
drivers are deleted. Delete this device from Device Manager.
The same procedure may be used also for complete removal of Alcohol
drivers from system.
