HORM: Reboot after hibernating

HORM is used on the previous target PC with Intel 915 chipset and 'Standard
PC'-HAL. Initiating hibernation (= generating a hibernate file showing the
progress bar) is realized by a tool which is calling the function
SetSuspendState ( Hibernate, ForceCritical,DisableWakeEvent ) as described in
the MSDN article 'Dismounting Volumes in a Hibernate Once/Resume Many
Configuration' (http://msdn.microsoft.com/en-us/library/aa460084.aspx) and
works without problems.

But the new target PC with Intel 945 chipset and 'ACPI Multiprocessor
PC'-HAL performs a reboot instead of power off after having written the
hibernate file with the same tool as described above!

What is the reason? How can this the automatic reboot be avoided?

Thanks in advance
Bernd

Try taking a look at the BIOS settings to see if S1 or S3 is set.

Hi Sean,

thanks for your suggestion.
In this case the undesirable behaviour of 'rebooting after hibernating'
could be solved by changing the value of the boolean parameter
DisableWakeEvent of the function SetSuspendState from FALSE to TRUE.

Kind regards
Bernd
