Automatically wake from sleep when lid closed?

I would like my MBP to wake from sleep when the lid is closed (no external monitor attached) in the middle of the night to initiate a backup to another computer. Is it possible to get the computer to wake up with closed and nothing attached? Do I need a third-party app to do this?
Thanks
Brian

But, that won't wake the computer up if the lid is closed and nothing else is hooked up to it. I want to wake it up in the middle of the night when the lid is closed and it is hooked up to a power supply.

Wakes from sleep when lid closed

i usually put my macbook to sleep by closing it. recently, it sleeps then a second later i hear the noise that it's waking. so while the computer is closed, the apple icon is lit as it's turned back on. ideas?

You might try the following procedure. I did it last night and I think it may have corrected the sleeping problem although at this moment I can't say for sure. A word of warning IF you do this procedure. It takes SEVERAL seconds and maybe even a minute to reboot after you do this 4-finger wave before the computer boots back up. A LONG time looking at a blue screen while I held my breath. This NVRAM procedure is buried toward the bottom in the link below. Since I read somewhere to do this procedure, I didn't get a chance to run through all the procedures listed in the link.
Reset NVRAM [Useful for: does not properly go to sleep; wakes from sleep while lid is closed; fails to wake from sleep]
A number of users report that resetting NVRAM resolves wake-from-sleep issues. In order to perform this process, shut down your Mac, then start it back up while immediately holding the following keys: Command, Option, P and R. Hold the keys down until the computer restarts and you hear the startup sound for the third time

Any way to prevent macbook air from sleeping when lid closed?

I believe there is no way to keep your macbook/air running when you shut the lid.
I am running a background job where I am downloading a huge amount of data from the internet, which is coming through slowly (other applications could be where I am running a web server....). I want the machine to be running, but not keep the lid open - since I might want to move the laptop, not leave the screen/keyboard exposed.
Where can I request Apple to add support for this behavior? Or did they anticipate this request in Mountain Lion already?
Any suggestions? Others who would like the same feature?

NoSleep makes closing of your MacBook lid possible without going into sleep mode. Now you shouldn't plug your mouse and monitor to stay computer awake - just check a tick in the System Preferences and continue downloading of huge files and watching favorite movies over the network with lid closed.

Wakes from sleep while lid closed

I got my MBP three weeks ago and I have noticed that when I have the lid closed and it is sleeping and I set it down it begins to make noise and when I open the lid I see that has already come out of sleep mode. I know that the MBP's have a motion sensor that shuts off the hard drives when it senses that the computer is falling or something. When I'm putting it down and it does this, it is always on a hard surface but it's not like I'm dropping the computer down, I'm gently placing it. Any thoughts?

That's cool.. It's good to see they fixed it on the latest revision. The college ordered these right before apple's last upgrade to the MBP. These are the 2.33 GHZ Core 2 Duo machines. The tech did mention that I could take these to the nearest Apple store.. a 2 hour drive, and one of the people at the store could evaluate them and then decide if they should be fixed. No guarantee they would.. and according to him and my description.. "the behaviour is expected.."
While it would be worth popping them into a fedex shipper to know they'd get fixed.. I guess I have to decide if it's worth a two hour drive to maybe get it fixed. The sleep sensor is such a simple and small part.. I'm reasonably confident I can fix it. I'll weigh my options in the next couple of days. Now that I know what's causing it.. I'm not as worried about it as I was. I had envisioned bare wires shorting out in the lid or something.
I will contrast Apple's support with Dell's though. I really despise Dell.. but, when the college has a problem with a machine, they send a part out no questions asked. The college has it's own tech support team and Dell will either send a tech immediately, or send the part to one of our team members. I'd really like to see the college choose more apple products. But, their response to our repair request has hurt that effort. Can you see us with a lab full of macs driving them two hours to an Apple store because of some hardware problem? We don't pay any extra for the Dell support, it's part of the product warranty. Apple could learn a thing or two...
I may stew on this a few days and call tech support again..

MBP often refuses to wake from sleep when lid is opened.

Hello!
Well, my MBP (2.2 Ghz, 15", Core2, 2 weeks old, 10.5.2) has been having trouble. That is, when I close the lid, the MBP properly sleeps. However, when I open the lid, it sometimes (Maybe as much as 40-50% of time!) won't wake up. The screen stays black, the keys won't do anything, and the sound wont' come on, but the sleep light turns off - as if it woke up. If I close the lid, it happily sleeps.
The only way out of this "mode" is to hold the power button for a forced-shutdown, and reboot. Its become worse after the 10.5.2 update. In addition, if I select "Sleep" from the apple menu before I close the lid, it seems to sleep and wake properly. On the other hand, if I just close the lid, it often won't wake up properly.
How can I fix this?
Thanks, Dan

Hi Daniel, I haven't had any significant sleep problems with my own MBP, but in general with other models sleep problems often come down to:
1) third party hardware 'add ons" (USB, FW, BlueTooth or ethernet) that "poll" the computer when it is either going to sleep or waking up. Some USB hubs and USB based ADSL modems were particularly notorious for this a little while back, but other devices, even memory sticks, have been known to produce such issues too. So if you have anything else connected see if the problems persists when it has been removed.
2) Third party "background" software, especially drivers associated with USB and bluetooth devices. Some earlier Logitech keyboard and mouse software could do this, for example.
3) Some specific other software that loads at startup - virus checkers, things like iStat, HD integrity checkers etc.
Remove all externals and then start up in "Safe Mode" (to disable log-in items etc - see http://docs.info.apple.com/article.html?artnum=107392 for more info), and see if the problem persists.
If it still occurs you may have a problem with a third party 'haxy" of some kind which has actually modified your system files.
Cheers

PB Wakes from Sleep When HDTV is Shut Off?

I have a 12"PB (10.5.6) hooked up via mini-DVI to VGA to a 47" LG HDTV (47LG50). I love this setup, but I'm having a problem keeping the PB asleep. When I'm done using the computer, I hit opt-apple-eject to put it to sleep and then switch the TV input to the cable box or whatever. The PB stays asleep successfully until I power down the television. At that point it wakes. When I try to put it back to sleep, the light on the front pulses once and then wakes again.
Anyone have any fixes for this? I'll even accept a work around, like having the PB sleep unless I hit a certain key combo or something... I don't want to leave the computer on for most of the day.
Thanks!!!

Hi, James. Not that I'm aware of. If there is, it probably involves entering commands into the Terminal, with which I have barely a nodding acquaintance. My one accomplishment in the Terminal has been instructing my MBP not to wake from sleep when the display is opened, and I managed that successfully only because someone more knowledgeable than I am told me exactly how to do it.
If that can be done, perhaps your computer could be instructed to ignore whatever little blip your TV set sends to the computer when you turn it off. But to do so, you'd have to know what the computer calls that little blip and how to incorporate its name into a command in the proper syntax. That's all well beyond me. I hope someone else will pitch in to help.

MBP Wakes From Sleep With Lid Shut

My MacBook Pro (only about 1 1/2 months old) wakes from sleep while the lid is shut. I close the lid to put the computer in sleep mode and wait until it has fully entered sleep mode (the white light pulsates). If I then pick the computer up and rotate it some, more often than not it sounds as if the hard drive kicks back on and the apple logo on the top of the screen briefly illuminates. Sometimes I have even noticed that the screen will illuminate; however, the most consistent things I've noticed are the hard drive and logo. This is all while the lid is still closed.
I spent around 1 1/2 hours on the phone with Apple support yesterday with no result. I thought I would see if anyone has an explanation or idea here before I send the computer off to Apple.

Hi again,
your statements that the workaround does not "work around"
on your machines confuses me a bit. It looks like the changes
in the com.apple.PowerManagement file don't produce the desired
effect.
First question: Did you restart your computers after having
applied the changes ? If not, try this first.
Can it depend on the model of MBP (I have the new Santa Rosa) ?
If I save the file as an ASCII file it looks like this:
ActivePowerProfiles = {"AC Power" = -1; "Battery Power" = -1; };
"Custom Profile" = {
"AC Power" = {
"Automatic Restart On Power Loss" = 0;
"Disk Sleep Timer" = 0;

"Display Sleep Uses Dim" = 0;
"Hibernate File" = "/var/vm/sleepimage";
"Hibernate Mode" = 3;
"Mobile Motion Module" = 1;
"System Sleep Timer" = 0;
"Wake On AC Change" = 0;
"Wake On Clamshell Open" = 0;
"Wake On LAN" = 0;
"Battery Power" = {
"Disk Sleep Timer" = 10;
"Display Sleep Timer" = 5;
"Display Sleep Uses Dim" = 1;
"Hibernate File" = "/var/vm/sleepimage";
"Hibernate Mode" = 3;

(German only, sorry)
And - I checked it just a minute ago - i works ! My MBP
goes to sleep when lid is shut and does NOT wake, when I
open the lid. After pressing a key, it comes to life again.
Regards,
Robert
P.S. Please have a look at the files in the
Library/Preferences/System Configuration Folder.
Is there only one file for Energy preferences or
did your system create another one, when you tried
to change settings via System Preferences ? I saw
this one time a few weeks ago, but I don't know
the exact conditions under which that happened.

MacBook won't automatically wake from sleep after flipping computer open.

The only way my computer both goes to sleep and wakes from sleep is by clicking on the Apple icon and putting it to sleep before closing the lid and by pressing the power button after opening the lid. If I just close the lid without first clicking on "Sleep" under the Apple icon, the computer will continue to run and the Apple on the lid will continue to be lit while the sleep indicator light does not go on. If I just open the lid and do not press the power button, the screen will continue to be black and the sleep indicator light continues to glow. I'm not sure if I reset a system preference or something by mistake, but is there a way to fix this? Or is this an indication of a bigger problem?
Additionally, when my computer is asleep and I unplug my charging iPod, it wakes from sleep (the sleep indicator light goes black while the Apple on the back of the screen lights up). Is this an indication of a bigger problem?
My computer is only about 7 months old, so I am a bit worried if it is starting to show wear and tear already. Thank you for your help!

You're welcome to the Forums.
Go to System Preferences>Energy Saver, and set a time for your System to sleep.
Set both sliders to 10 or 15mins to nod off, when Inactive.
It's never a good idea to plug in or out, while the Computer is sleeping. If someone pokes at your ear while you're sleeping, you'll wake up too.

MB pro not sleeping when lid closed

Hi, I came to work today, opened my backpack and found my laptop extremely hot in its sleeve. It appears it had not gone to sleep when I closed the lid. It then failed to run properly for about 20 minutes until it cooled down. Now it is ok, except that it will not run in lid-closed mode. I plug in my external display, put it to sleep, and wake it back up with the lid closed in order to use the external display. The display fires up for a few seconds and then turns off again. I've tried this over and over again, the computer simply won't stay on for more than a few seconds. However, when the lid is opened, it will run the external display in mirrored mode just fine. I think something is toast. Coincidentally, I had just downloaded the keyboard update 1.0 a day earlier... Anybody know why my computer is not sleeping when I close the lid and why it won't work in closed-lid mode anymore?

I've had a similar problem since I first got this a year ago. Sometimes when I shut the lid, the display does not go to sleep, and sometimes it restarts automatically when I shut the lid! I've also found it very hot at times when it should have been sleeping. So far, it's only been a minor annoyance.

Black screen upon wake from sleep when I change power state while in sleep

Hi,
I'm having this problem where my MacbookPro won't always wake from sleep.
OSX is 10.6.3 and fully updated.
I've done a lot of troubleshooting, and I can now replicate the issue 100%:
1 - Put the MacbookPro to sleep by closing lid
2 - Change power source (from plugged-in to battery or vice versa)
3 - open lid - MacbookPro will wake, but stays at black screen and is unresponsive.
Only if I change power state while sleeping will this issue show. Anyone else experincing this issue, and anygot got a clue on what to do?
regards,
Lasse

I've seen the same issue after upgrading to 10.6.3. I have a one year old MacBook Pro. I would have the screen be black after coming back from sleep or hibernate (tried both).
The workaround I found is to close the lid -almost- all the way and then immediately open it back up again, like I am catching the Mac going back to sleep and then changing my mind. For whatever reason, this has been reliably solving my issue for the last couple weeks reliably.
Only other oddity I noticed is that immediately after upgrading OS X told me that my one year old battery needed to go in for servicing...
Anyway, now all looks right with the world assuming you don't mind a quick close/open cycle.. Lovely...

Computer not going to sleep when lid closed

My wife's new MacBook Air has a couple of problems we can't figure out. First sometimes the computer is not going to sleep when lid is closed and when we lift the lid everything is frozen.
Second, the user Library folder is not seeable in her user account. I know it's there because on the side bar there's a short cut to Preferences folder which we can open.
Strange behavior.
Thanks,
Ron

Ron,
The user library folder (~/Library/) is hidden by default in Lion. I assume Apple doesn't want people mucking around with the sensitive files in there. So this is normal behavior.
As for the freezing issue, I would suggest you reset your power management and perform a safe boot to clear out caches. You should also see if the issue persists after disconnecting USB perhipherals.
Here's how:
Power Management:
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
Safe Boot:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).

Powerbook won't wake from sleep when unplugged from power

hi everyone,
i have a 15" 1ghz titanium powerbook, running 10.4.6.
recently (maybe since 10.4.6?) i haven't been able to wake the machine from sleep when i unplug it from powering up in sleep mode, to open it up someplace else to run it on batteries for a little while. i always have to do a hard-reboot (holding down the startup button for several seconds). this usually destroys my dock and other preferences when i'm "back in".
does anyone know what might be causing this? it seems to be a recent development. it's unpleasant, because i frequently have the powerbook charge itself while asleep, and then i want to unplug it and quickly do something in another room running it on batteries. afaik sleeping and awakening works fine as long as i don't plug/unplug the power cable before waking it up.
any hints would be greatly appreciated...thank you!

PowerBook G4 15 1 GHz Mac OS X (10.4.6)

Hi A.L.,
I have a Cinema Display which I often use on the back of my Ti. I know the laptop will not wake if there is no power and it has an external DVI display attached.
Perhaps your computer thinks it has some monitor attached - perhaps checking the DVI port for damage would be worth it?
Regards,

HT1338 Imac won't wake from sleep when a facetime call comes in

My Imac will not awake from sleep when a FaceTime call comes in.

I've had this problem several times now, and I do no own MobileMe. I don't use any bluetooth peripherals, but I've noticed that the precursor to the problem is that my bluetooth icon in the menubar goes from normal to "Bluetooth Unavailable." Then at some point later on, I put the iMac to sleep and it won't wake up.
I've read elsewhere that the bluetooth unavailable problem may be connected to the power management unit, which may in turn explain what is going on with it not rebooting. But I'm not sure.

Wake on wireless possible? Disable sleep when lid closed?

I just bought my first Mac & am still trying to figure some things out.
Is there a way to have it wake on wifi? I like to be able to connect to my machines when I'm at the office. My Macbook goes to sleep & then I can't remotely access it. Wake on LAN works fine, but I don't want to keep an ethernet cable plugged in.
Another thing I can't seem to get is how to disable the Macbook sleeping when I close the lid. On my old Windows laptop, I'd often put on a podcast & listen while falling asleep & have one start as an alarm clock in the morning. I like to keep the lid closed to keep out dust, etc.
I found a 3rd party app InsomniaX, but would rather find a supported way of doing this.

Insomniax is your best bet. The only other way would be have an external monitor, keyboard, and mouse hooked up.

My mbp doesn't always wake from sleep when I open the lid

(mbp is recent thunderbolt version)
TItle says it all really.
Usually I can coax it back from sleep by closing lid and leaving for a minute a few times. Annoying.
Sometimes, briefly pressing the power button seems to give it a jolt and back it comes.
Hopefully this is a software issue and an update will rectify it. Please let me know if this is a hardware problem!
Thanks

oups .. wrong post. sorry ...

Open Disk Utility and perform a permissions repair on your system disk, as updates and so on can mix the permissions on system files up.
Don't bother about upcoming warnings during that process. It's normal -> http://support.apple.com/kb/ts1448
After that, your system should work fine again.
