Macbook Pro won't sleep when plugged in

same here, quiting powerd worked, and so did quiting my printer que, way to easy to miss imo.

This was driving me crazy! Wouldn't sleep with power plugged in. Closing the lid would put the screen to sleep but when I opened it again, the screen would light up a few seconds and then go dark. Quiting powerd worked for me too. Thanks.

For me, it was internet sharing. I had my WiFi shared over ethernet.

As soon as I disabled internet sharing, violia! Back in normal sleep mode!

Thanks - that also fixed my problem!😉

As soon as I read that it might be a print queue issue, I remembered that I hadn't printed something. So, I went to the queue and deleted the unprinted item, and voila. Macbook Pro now sleeps. So simple. Thanks LoRob.

Thanks LoRob. This solved my problem too. Never had a problem with my MBP going to sleep until last night and it was driving me nuts. I was about to try the usual suggestions, but I'm glad I saw your post. I totally forgot about accidentally printing to an offline printer.

For me it was definitely a print item stuck in the print queue. Open Print & Scan in system preferences, select any printer(s) with a red or yellow badge, and then click the "Open Print Queue" button to show the print jobs and delete any that have not completed. Seems too darned simple to work but it did.

Thanks LoRob,

This was also the case for me. I can't believe this was the problem the whole time... this should be patched by apple asap. It's stupidly simple, yet I had to google it and waste 45min of my life to fix it!

Again, just try as LoRob explained above.

LoRob, you seem to have fixed my problem as well. Awesome! What a silly thing to mess things up. Thanks!

This worked for me, too. The apple store folks had me reinstall the system and then my backup from time capsule. That FAILED to fix the problem.

Sorry for the multiple posts. I just now figured out how to quote the message text.

Thanks LoRob. This truly worked. I had some stuff stuck in a print que from 7 months ago! I don't remember this being an issue earlier this year, but maybe it was.

Print Que Limbo!

There's a little utility that works in Lion called PleaseSleep that might help you out. I was having the same problem on a 2006 MBP running SL and it did the trick. Migrated over when I got my new MBP and it still worked under Lion.

You may want to give it a try.

I have 10.7.3 MacPro 2008 3,1

I temporarilary fixed this issue by killing the powerd process

I fixed this issue when I stopped sharing internet access from wifi to ethernet

System Preferences > Sharing > (untick internet sharing)

Thanks schnautz07! I have been dealing with this for about 6 months, and you solved it!
