has anyone noticed a difference in the HIBERNATE or SUSPEND modes when you close the lid on your laptop?

no matter what i choose, the laptop is still warm the next day.
i thought one of those was to put the laptop into a sleep like mode which basically turns everything off but not totally off.

any ideas?

and i just noticed (after a night) that the fan must have been running all night long too.
surely there must be a way to 'sleep' this laptop, or?

am using a samsung series 9 if that makes a difference.
