What is the difference between suspend by closing the laptop's lid and clicking Logout\Suspend

[Athlion]

Thanks for the reply!

When I say failed, I mean that the system does not enter suspend mode
and X drops back to the login manager. Other than that, everything
*seems* to be OK. But after that failed suspend, if I initate a
reboot, the system suspends midway! If I then resume it, it continues
the reboot.

According to the logs, both ways enter S3. I really am looking to find
the difference between closing the lid and clicking Logout\Suspend
because the first fails after 24 hours of suspending/resuming and the
second never fails....

This is something that affects a wide range of laptops and
distributions, see here:

(Disregard the title, it does not seem to be connected to 3.4.x kernel)
