Closing Lid Does Not Sleep MBP

I have a 15" Macbook Pro. And just in the last week. when i shut the lid, there is absolutely no affect on the computer, it doesn't even attempt to sleep.

And I've not and never have had any of those programs that stop your laptop from sleeping.

The first time I realised was when i picked up an absolutely scorching hot macbook from my laptop bag, after a 1hr and a bit drive to uni.

I have repeated numerous times, restarted and then tried having no applications open, but it refuses to sleep.

I should also point out that it sleeps properly when i select it from the menu

Regards

Takumi

!!EDIT: i should add it isn't the same symptoms as other cases of it sleeping the waking ans sleeping. it just doesn't sleep at all

Macbook Pro 15", Mac OS X (10.4.7)

It is not a good idea to put your machine to sleep when traveling. Shut it down if you are going to travel any distance beyond the same room. The shaking and jarring motion could in theory damage the hard drive. I damaged three hard drives this way on bus rides that had many potholes. Now if the lid is not letting the machine sleep when no other programs are running, it sounds like you have a problem with the latch which needs to be looked at by AppleCare.

I found that if I reapplied my removal of 'deep sleep', the issue seems to be gone. Try the following. At the command prompt, type:

sudo pmset -a hibernatemode 0

Then logout, log in again, and it might solve the issue for you.

I believe I have the same trouble since 10.4.8 update. I hook up an external monitor then close the lid of the MacBook Pro to put it to sleep. I would then tap a key on the external keyboard to wake the external monitor and away I would go.

Since 10.4.8, hitting the external keyboard does NOT wake the laptop while it is closed. Also, if I re-open the MacBook, its monitor is black and the external monitor is also black. It's as if all video signals have been wiped out.

Happens about 50% of the time for me.

Also had an issue where after waking the laptop, its video resolution reset to lowest (800X600?)

There is definately a problem in 10.4.8 between sleep/wake and the video card.

i'm also having the problem where the mbp will not sleep when the lid is shut, just the backlight shuts off. the backlight will also not turn back on when try to wake it, making me have to restart the computer.

another problem is i can't seem to control the sleeping. i turned sleep to 'never' and when i come back from class it's sleeping!

this never happened before.

i'm having a lot of problems with this computer lately... i wish i could get a refund and get a 24" imac.

Fixed the problem did two things - noticed that system preferences had been changed to sleep never - after the update... changed that...

also reset the pmu... can't tell you if this was necessary as i did both at the same time... but I can say that I closed the lid on my charged MBP over night and in the morning it was not warm nor was the battery depleted. hope this helps.

I am having the same issue and went here to see if it was going on with anyone else. I'm thinking of reinstalling the 104.7 update and seeing if that fixes the problem.

Is it that easy? Do you just download the 10.4.7 disk image and do an install?

Oct 6, 2006 6:21 AM in response to Andrew Robulack

yup!

Another interesting pattern I've noticed: my MBP will only sleeping with a pulsing light when the lid is up. Even if it's in a sleep state with the light pulsing, as soon as I shut the lid, the light goes solid and it seems to come out of sleep.

The machine seems to run much more warmly than before, even when supposedly "sleeping". This is especially true of the rear left-hand side. I've never noticed it to be so hot that I can't even touch, even when I've not been using it.

Even before 10.4.8, if my machine was asleep and I closed the lid, it would wake. Then when opening the lid, it would sleep again.

Odd behavior, yes, but I don't think it's new to 10.4.8.

I've always had my settings to sleep never when on AC power, and before 10.4.8, my MBP would still sleep when I closed the lid. Changing that setting should only affect how long the machine waits without user input before it sleeps itself, not whether or not it will sleep when the lid is closed.

One caveat: Aperture 1.5 likely won't operate if I do that. So: the choices are: downgrade to 10.4.7, go back to Aperture 1.x and reduce the stress on my battery, or stay where I am and use Aperture 1.5 but likely wear out my battery more quickly.

Two bad options. Yuck.

Just noticed something interesting, if I turn AirPort off before I close the lid my MBP seems to go right to sleep. It still wakes up a little slow, but not as bad as when I left AirPort on. If nothing else it is worth a try.

Yes, mine did this for the first time today also and I just installed 10.4.8. While this might not be the problem it definitely seems to have kicked started the problem for some that were not having this issue before.

Quite alarming to open what you thought was your sleeping laptop and have it be so hot !

Try to make a PMU reset.
It solved the problem for me.
