question....my apple doesn't "sleep" when I hit the sleep button....

[a kennedy]

When I first bought the machine, this past July, it turned off right when the sleep button was pushed.....now there's like a 10= 15 second delay what's up with that?? I am not doing anything different either. Is it just slowing down?? Thanks for your help.

1. Check to see if you have any print jobs still in the queue

If you do, delete or print them and try again.

This link also says it could be the print queue.

They mention a Google plugin too.

Got a feeling the more processes you have running, the longer sleep will take.

2. thanks alfredo.....but I didn't have any printing in the queue

*shrug* not sure what's going on..... I'll check out that website too.

3. Putting my mac to sleep takes a variable amount of time. At minimum, this involves

writing RAM to harddisk. I don't know the internals, so take everything else I say with a big cube of salt

(1) The system might keep track of what RAM has been accesseds since (say) last boot; if you reboot frequently, there might be less RAM to write to harddisk than if you seldom reboot -- so maybe rebooting now and then would reduce time-to-sleep
(2) Going to sleep might invoke some autosaves or writing to tempfiles for some applications; if you have lots of apps open, this might slow going-to-sleep
(3) If your harddisk is getting full, then writing RAM to harddisk might use slower portions of the harddisk than previously; there could be a similar slowdown (for different reasons) if you've been using a solid state disk

4. 2 and 3 might explain why it was fast at first, but slower now.

5. hibernate

It's likely just waiting for the hibernation disk image to be written out (all of memory). This lets you recover ("wake") if the battery drains to zero while you're sleeping.

The write to disk could be slower if the disk is getting full enough that it's fragmenting. Or (more alarmingly) if the disk is starting to fail and it's doing retries to get it to write successfully. I'd check for "disk i/o" errors in /var/log/kernel.log.

Alternatively, it could be wake-on-lan (or wake-on-wireless) taking it's time. You can test that by just turning off 'wake for network access' in system prefs / energy prefs panel and see if that makes it faster.

6. what's the sleep button?

7. Under "Apple Icon >> System Preferences >> Energy Saver," it is

possible to select a checkbox "Allow Power Button to Put the Computer to Sleep"

8. ok thanks

9. My Mac started this behavior after the latest OS update

Until then it would go to sleep nearly instantly. Now I wait to see if it reanimates. Then I put it down again.

I swear, it's like a damned zombie now.
