Have you created a swap partition that is bigger than the amount of
system memory you have?
Hibernation uses the swap partition, so if you have say 2GB of memory
then you need to allow 2GB for hibernation plus a little bit extra for
anything that might be swapped. Personally as I have 4GB in my notebook
I found Hibernation took longer than booting up so I don't use it.
When you suspend does the laptop appear to power off?
On my laptop when I suspend it will take a few seconds then it will
appear to power off but the power LED goes amber and flashes. Pressing
any key resumes the laptop. Saying that though I believe I had problems
with Suspend on an older version of Ubuntu.
(Not to mention in suspend mode, although it powers the machine off
pretty much, it still does drain your battery so if you have a low
capacity battery you don't get that much longer in suspend mode).
