Battery drain while lid closed

PaulCostello · Dec 25, 2012, 10:19 AM

It started a few days ago. I make sure my 2012 11" is fully charged at evening time, close lid and put my macbook away. I wake up in the morning to find it at 85%. I haven't installed any new programs, power nap is turned off, cant seem to figure it out. Any suggestions? (BTW, I've had my macbook for about 4-5 months and never had this issue) thx

Sure, turn it off.

My 13" 2011 MBA loses about 1% overnight while sleeping. From previous threads that seems to be about normal. Your number is way out of line.

You likely have something running in the background that consuming the power. My 2012 11" will lose ~1% overnight with nothing running. However if I leave my Windows 8 VM running I'll lose close to 40% overnight.

Must just be another reason why the new windows sucks lol.

Are apps that you had running before you close your lid and let your mba go to sleep, affect the battery life while it's asleep? I had no idea...

So if I had Chrome open with flash running and stuff and let it sleep, it would actually drain more battery life than if I had fully quit Chrome and let it sleep?

No, that isn't the case. The computer is dormant when it's asleep but it sounds like it's not actually staying asleep. My 2012 11" Air will hold a full charge for a long time when it's asleep. Do you have it set to wake for network access?
Also, the first version of the supplemental update for 10.8.2 caused the computer to go into an endless wake/sleep cycle. What build of OS is on yours? (Go to About this Mac and click on the version number.)

If it's app that can force it to wake while the lid is closed then yea I believe it can. Windows VM's in Fusion are the only things I've seen on mine that will do it. Outside of Fusion I can leave anything else going (and regularly do) and it doesn't drain hardly at all. I'm not sure why Fusion and/or Windows VM's do it, haven't cared enough to try and figure it out honestly, I rarely run a VM on my MBA heh.

Chrfr above mentioned Wake on LAN, which can cause it as well. Also yes ensure you have all the latest updates.

I don't close any apps, I just shut the lid and I lose less than 1% each night.

From reading this thread, it seems that I may have a problem also....
