Auto-sleep requires longer time then chosen

[DennisMadsen]

Yesterday I did a clean install of Mac OS X Lion on my MBP 13", medio 2010. I have noticed that it, in case of inactivity, takes longer time doing into computer auto-sleep than I have chosen in Energy Saver in Preferences.

If I set computer sleet to 1 minute, in really takes 6 minutes. 5 minutes takes 7 minutes and 10 takes 12 minutes.

Why?

What does it say if you open up Terminal and type "pmset -g" (if your on battery or plugged in, this will show different values)?

Here is the output:

In Energy Saver I chose 1 minute for both display and computer sleep. Is it a problem, that the disksleep is 10 minutes?

One of the bugs I've got after conversion is one system won't auto-sleep at all. I've converted 4 systems and only one is misbehaving.

There could be some activity keeping these systems awake longer than they should. There's a knowlegebase article on this with steps that should be taken. (Alas, didn't do any good for me, but might for the OP.)

Is there a way to monitor which application doing disk activity?

First try doing a SMC reset, if that doesnt work then open up Terminal and type "sudo pmset -a ttyskeepawake 0"

ttyskeepawake - prevent idle system sleep when any tty (e.g. remote login session) is ’active’. A tty is ’inactive’ only when its idle time exceeds the system sleep timer.

Thanks for your reply.

I'm running on battery and computer sleep are set to 5 minutes.
I did a SMC reset. But still it took ~13 minutes to sleep. The same after I disabled the ttyskeepawake.
