Prevent MBP13 from sleeping when closed power & ext display?

hi all,
i use my macbook with an external monitor and keyboard. i normally have my macbook charging and the lid closed.
i unplugged the mag charger and my external monitor went black. however when my lid is open and not charging everything works fine.
so my question is why does everything work fine when my mac is running on power and lid closed but does not when lid is closed and an running on battery. (however does when lid open running on batt)

Hi Radium88,
You can prevent your MacBook Pro from going to sleep using the steps in this article -
OS X Mountain Lion: Prevent your computer from sleeping
http://support.apple.com/kb/PH10679
Specifically -
Choose Apple menu > System Preferences, and then click Energy Saver.
Drag the slider that controls the computer’s sleep to “Never.”
Thanks for using Apple Support Communities.
Best,

How to prevent computer from sleeping when downloading Lion from the recovery partition?

Hello,
I just got a new MacBook Pro that came with Lion. I'm reinstalling from the recovery partition and I'm on the downloading additional components stage. It has 3 hours to go and the computer keeps going to sleep. How can I prevent this? I don't want to have to babysit the computer for 3 more hours.
Thanks.

Looking for an answer to this question now. Did you find one? I'm about an hour into a 6+ hour reinstall of Mountain Lion from the Recovery partition on my MacBook Pro. So I can't change the sleep corners or caffenate it or do much of anything but wait. I want to go to bed and let it install overnight, but I assume it will go to sleep, and that will kill the download. It there any way to prevent it from sleeping now?
Even trying to think of something I can put on the trackpad to trick it into thinking I'm touching it.
Maybe ill put it under my dog, and her movements will keep it awake? Thinking outside the box here.
Any ideas would be appreciated.

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.

Waking 2012 Macbook Pro from sleep when on mains power

My Macbook takes ages to wake from sleep *when its on mains power* and has been left for a few hours. In contrast, it will wake instantly when on battery power, as my old 2005 ibook did.
However when on mains when you open the lid, you get a progress bar at the bottom of the screen. When this has completed, it displays the login screen but without focus or ability to move the cursor. A pinwheel revolves for a while. After the pinwheel has finished, as soon as you touch the trackpad, you get the beach ball and finally (after a total of about 45 seconds) you get to log in.
Apart from the fact that this doesn't make any sense for a slow wake up on mains and fast wake up on battery, the manner is which it is executed is so cumbersome and un-Apple I'm sure there has to be something wrong, although I've searched extensively and can't find anything to fix it (Tried resetting the SMC etc)
Any help massively appreciated!

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!

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?

How to stop my Time Machine external hard drive preventing iMac from sleeping?

I have a late 2012 iMac, and have discovered that sometimes (I haven't noticed a pattern of when it doesn/doesn't happen) the computer will immediately wake up after I set it to Sleep (Apple Menu>Sleep). Through elimination I have found that it is the the USB 3.0 external hard drive I use as a Time Machine back-up that is the culprit; unplugging it then allows the computer to sleep. If I unplug it, then plug it back in later on, this normally solves the problem for a while, but not forever. This same Hard Drive didn't cause the wake problem on my previous '08 iMac.
A big issue is that when the machine immediately wakes from sleep, the display stays off (until I move the mouse) - this is good from a power saving point of view, but means I don't know if/when the machine is immediately waking from sleep (I have to listen to the fan when setting it to Sleep mode to hear if it has actually woken back up).
I've searched the forums, but can't find another poster with the same problem as myself. Can anyone advise a course for me to pursue to prevent this from happening?
Thanks. Jamie

Hi Frank. Nope, I'm still having the same symptoms; the plugged in external drive (TIme Machine) will wake the machine up a couple of seconds after it winding down when put to into sleep mode. Ejecting the drive and then sleeping the machine works. After plugging it in again to do a Time machine backup, it will allow the computer to sleep soundly for the first few sessions (eg a few days of sleeping, waking, sleeping, waking, etc), but then it will then suddenly start preventing it from sleeping again after a while.
It seems I'm fortunate in my case that the display stays dark (or off?) when the machine has been woken from sleep, but this was actually preventing me from knowing the machine wasn't in fact asleep for quite some time; I only eventually cottoned on because there wasn't any delay when 'waking' my machine (which there normally is). I would then have to carefully listen to the spinning fans to know if in fact it had gone to sleep or not.
So, to summarise, unfortunately no, I haven't solved this yet. If anyone else has a solution, please let us know?
Also, I've noticed occasionally after waking that there is a relatively quiet 'crackle' sound (kind of electrical sounding) from the bottom-right area of the machine. This goes on every so often for about 30mins. I see this is also an issue with other people's late 2012 iMacs, but I've not seen if anyone has a solution to it?

How to wake from sleep only with power button

Hi,
I still use this old PowerMac G4 (hopefully Apple builds a new MacPro soon!) and when not using it, it is in sleep mode.
Unfortunately my cats like to touch the keyboard, thus waking up my Mac.
Is it possible to wake the mac only by pressing the power button?
If so, how?
regards
kpgkpg

The USB bus is unique from other buses in that it always has power present to it.
Because of this, it can be used to sense activity at a keyboard or other input device to facilitate wake from sleep.
The power button also always has power present, with the main purpose of on and off being extended to options for sleep and wake. This is possible due to the use of a momentary contact switch, with fuction that can be interpreted (time held) for various purposes via software.
why the action on the USB bus has to be a keyboard inpput, but not a mouse click. strange.
Mouse click should also wake the machine if the mouse is USB. If Bluetooth, an option must be selected in the software, and then not all mice are equal.
If wireless, then, again, not all are equal. Some will wake a machine, others won't.

Macbook Pro wakes up from sleep when express card inserted

Hi,
my macbook pro (no unibody, 10.5.7) wakes up from sleep when I have my express card 34 (Hama 16GB) inserted. Is there any trick to disable wake up when a drive is inserted? I tried to eject the disk before going to sleep with a shell script but it automounts the device... I attached my log... I hope somebody can help! Thanks a lot!

Hey, thanks 4 your response... Well I figured that out... I hoped that there was a way to prevent system calls, regarding devices, to wake up my macbook pro... something like: forbid interrupts while asleep
If you ever hear of a way to fix it please let me know...
I think a solution would be to disable automount on the express card device... I use it for my time machine backup and really DON'T want to remove the card every five minutes...
Cheers, Philipp

Macbook pro not turning on after SMC reset. I have the following problem. Yesterday I noticed that my mbp 2011does not sleep when closing the screen. smc due loud fan and an X on battery symbol

Yesterday I noticed that my mbp 2011 dos not sleep when closing the screen cover. Today I Turner my laptop in. However the fan was working loudly and stayed loud. After Start I noticed an X on Battery symbol. Clicking on it, it showed 'no battery.' I found out that a potential solution for this problem was SMC reset. I also noticed that the leds on magsafe was not lightning. Despite this I tried to execute the smc reset as described on apple support site. Switching off, plugin the magsafe connector, pushed the buttons shift + alt+ ctrl + power. Then i pushed the power button, but my mbp is not turning on. I pushed several times on the power button but nothing works. The magsafe is also dark meaning the leds not lightning. Can anyone here help me on this ?

Problem solved by my own. But do not how :) magsafe again working and the laptop tooo

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.

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.

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.

When you connect the device open iTunes and select it from the sidebar. Click on the Summary tab in the main window. Uncheck the option to automatically connect to iTunes. You will find it in the collection of options near the lower part of the window.
