OS X Lion 10.7 Sleep Issue

I can get my MBP to sleep - the problem is that it freezes after being a sleep for a period of time. The only way to fix the problem is a hard restart. This can't be what Apple intended.

Had the same sleep issue(s) that are described in this post.

Turning internet sharing off solved them.

Also: The problems didn't occur when I unplugged the power adapter on my macbook pro. Sleep works perfectly when working on battery power. Might be an easier workaround for people who really need internet sharing on a macbook and don't feel like turning it on and off manually all the time 🙂

Hello,

same problem with sleep here, ran what you told found out the problem was with 23 and here is the answer:

the command ps -ef lgrp -e 23

the answer

ps: illegal argument: lgrp

usage: ps [-AaCcEefhjlMmrSTvwXx] [-O fmt | -o fmt] [-G gid[,gid...]]

[-g grp[,grp...]] [-u [uid,uid...]]

[-p pid[,pid...]] [-t tty[,tty...]] [-U user[,user...]]

ps [-L]

Thanks for your time

Hi Claude,

You made a typo, it's ps -ef | grep... you forgot the "e" from "grep".

But... What it's doing is to display every process which contains "23" in its name or other stuff (process id, etc), you only want to know which pid is "23"

Please try : ps -S 23

It should works.

I'm concerned by the sleep problem and that command (pmset -g) displays 45, the number of minutes I configured before my mba goes to sleep.

Bye,

Arnaud

Thanks Arnaud,

stupid mistake. I know one must always be precise with those text commands. So I was able to find the problem was supposedly the cupsnd, also the internet sharing of my printer...but it's not on...

so did'nt really help.

By the way mine displays 4200 before going to sleep...very interesting and mysterious.

Thanks again for the information even if did'nt solve the problem. We tried.

Bye,

Claude

Exact same problem here. Putting MBP to sleep with Lion causes it to just plain die. Opening the lid and pressing anything does nothing. Only hard reboot brings it back up. An it usually ain't too happy when I do. :(

Ready to go back to SL.

@SirUno - I had the same problem you're seeing. My fix is described on the 3rd page of this thread (replace SystemConfiguration folder). My system has worked fine since then. Good luck! BTW, I'm on a late-2008 MacBook unibody ... sometimes connected to a 24" Cinema display.

@Adub...hey I tried that and it seemed to have worked (for now). I'll let you all know tomorrow if things get dicey again.

Also running a late 2008 MBP Unibody...no external monitor though.

I had the same problem my hard disk wouldn't go to sleep.

Iturned off fille sharing and my problem is gone

Thank you verry much🙂

OK...it worked for a time. Up this morning and it is back to it's old antics. :/

Hafta try sompthin else. Thanks for the assist.

@SirUno -- sorry to hear that. At first, manual sleep on Lion was fine. That it went south after a few days, identical to what you described. My fix is still holding on ... hope you find a good solution soon. Definitely a pain ...

@ADub...Thanks. I am now paranoid to close the lid. Hahaha! Oh well, if I can't fiugure it out soon, I'll simply revert back to SL and wait for a more stable version of Lion.

Thanks.

Well this stinks. Brand new macbook pro 13 inch and I come home to a very warm machine... I left feedback already for Apple that Closed Clamshell Mode is not even an option in systems preferences..

Check this out. I hope it helps.

Hello,

the problem is resolved here.

The story:

In fact after installing Lion I had no problem with sleep plugged or unplugged. The very temporary display problem and the not going to sleep when plugged started after:

a. I installed Logic studio.

b. I bought an airprint capable printer. (both the same day last week and both worked without problem).

Yesterday I installed 2 things:

a. an update for logic studio

b. an update for the printer (The printer installed it internally without passing through the computer).

After that, distracted, I closed the lid without unplugging and to my surprise the light started blinking.

So two hypothesis: logic studio, maybe the soundcore? Or more probably a trouble in the communication through the router to the printer caused by the printer. Something like the connection not being able to go off and keeping the computer awake.

If this can be of some help...
