[Bug 73174] Re: Hibernate and suspend do not work

[Luka Renko]

quidance-power-manager only instructs HAL to suspend/hibernate and then
everything is done by acpi-support and kernel to properly suspend the
system.

I would suggest that you try this first from the console prompt with
"sudo pmi action suspend" and "sudo pmi action hibernate" - this will
provide you more details (log messages) of what may went wrong.
