Ok...this is the second time this has happened. I shut my macbook expecting it to go to sleep. I then put it in its booq sleeve and put it in my back pack. About 40 minutes late i pull it out of the case and it is WAY hot and the fan is going like crazy. I open it up and i cant do anything, i think because it is over heated.

what is the deal? Has anyone ever had this happen to them? any help will be appreciated...thanks
 
I'm not sure why it happens but it only seems to happen to me when i put the computer to sleep in clamshell mode.

The computer hangs and CPU usage goes to 100%.

The only way back out of this is a hard reboot for me as well.

Regardless of whether I wait 1 minute or don't realize it and put it in its sleeve and wait 30 minutes.

Hopefully a future OS update will fix this.
 
This exact thing happened to me as well. It also happened to me when I shut down my macbook and close the lid before it finishes. Anyways, it seems like it's off, I put it into my booq vyper XS2 and after I get home from work the computer is blazing hot and fans going full blast. I don't know if I should take it in to apple or what. Sorry can't be too much help.
 
alrighty, i have cooled down my computer and now have the joy to post from my macbook instead of the crappy dell lab computer... here is the report for anyone that can decipher this:

i have no clue what this means...or how to prevent this in the future...
 
i didnt tell it to go to sleep, i just shut the lid...should i manually go to sleep before shutting the lid?
 
i can answer this. this also happened to me. even though you put your macbook to sleep its still on and most likely its still heated up and your putting it in a warm place were it cant breathe so it tries to cool itself down with its fans on max.
 
"i didnt tell it to go to sleep, i just shut the lid...should i manually go to sleep before shutting the lid?"


I had some sleep issues with my MacBook right after i bought it in august of 06 so here's my 2 cents. By shutting the lid your telling it to go to sleep. Yes you can manually tell it to sleep but shutting the lid should do the same thing. If you shut the lid and wait about 20 seconds, does the light on the front go from steady bright to a slow pulse? if it does your computer is now sleeping. if not, the magnets that keep the lid shut and signal your computer to enter sleep mode may be misaligned which may be why its still on and running.
 
Same problem here (with a Macbook Pro). It's happened a few times--occasionally, the computer just doesn't go to sleep when I shut the lid.

A couple times, I haven't caught this until much later when I discover an extremely hot computer in my bag with the battery depleted and needing a hard reboot to turn on.

A couple other times, I've caught this within a few minutes and found it had continued behaving as it would had the case been left open (a couple downloads had made progress, and Gmail Notifier said that it had checked my email during the time it was closed).

I really hope there's a firmware/OS fix for this soon. Or is it a hardware problem?
 
This hasn't happened to me personally, But it has happeend to two friends of mine, each with a CD MBP. One had a glossy screen which now has marks burned into it.
 
yes, it's happened to me. It actually happened today (but I caught it quickly). I don't know what causes it, but it is pretty frustrating.
 
It happened to me again, and I did everything I could think of to make sure it would go to sleep. Now I'm so paranoid that when I drive home from work I have my incase bag and booq sleeve opened a bit just so I can feel the computer to ensure it's not blazing hot. Apple really needs to fix this since it doesn't seem like an uncommon problem with us CD MB and CD MBP owners.
 
A little update on mine:

It's not a latch issue. When closing the book was failing to put it to sleep earlier today, I instead just tried telling it to go to sleep through the menu. The computer just sat there functioning as if I had never told it anything. It wouldn't sleep this way either.

I had to restart to get the sleep function working again.

So hopefully it's an OS issue that can be corrected...
 
Everything is up to date. My hope is just that the problem seems common enough, they must be working on a fix.

For the time being, I'll just have to be a little paranoid and double-check if it's really asleep.
 
once it goes to sleep, you are fine. So just make sure the sleep light starts "breathing" once the computer is closed, and you'll be ok. When this happens, it starts at the time you close your computer.
 
I had the same occurence several times with my CD MBP, and the best way to cure my MBP's insomnia is to do a restart. After that, the problem dissapears. Another option is to just sleep your computer by pressing command+option+eject.
 
I have a brand new CD MBP and am running into the same thing... most of the time closing puts it to sleep, but after a while it won't sleep when shut. If I restart, its fine for a while but will eventually have the same problem again. When I shut it, I have to wait a few seconds to make sure the light starts pulsing and I then know its sleeping. If not, I have to shut it down. I tried putting it to sleep manually when the problem first cropped up, and it would, but it woke up when I closed the lid.

When I have the time, its going in to get fixed. I'm a bit disappointed that my first Mac is already flaky after just 2 weeks. It was problems like this that made me decide to get a Mac in the first place...

Make sure there are no programs which could be waking your MacBook from sleep, for example iCal Alarms. A big one is to check to see if 'Wake for Ethernet Administrator Access' is unchecked in the Energy Saver preference pane.

I had the same issue with my MacBook Pro, and it was because something was waking it from sleep...

LIKEWISE! (sense the frustration?)


i even brought mine to the genius bar when the problem emerged again, demonstrated it wasn't going to sleep, and they took it in. the engineer couldn't replicate the problem (of course, it was probably shut down and restarted before the engineer got ahold of the thing!) since then, motherboard replaced due to loud (to my ears) whine, but even still the problem persists. (so it's not a motherboard problem, like the guy behind the genius bar thought it was when the sleep problem was demonstrated to him...)



anyone have luck on this?

Just make ABSOLUTELY sure you are up to date with the latest EFI
on your MBP

Boot ROM Version will be:
MBP11.0055.B08 (MacBook Pro 15 inch)
MBP12.0061.B03 (MacBook Pro 17 inch)

You can confirm the version of the Boot ROM installed on your computer using System Profiler.
 
Ive got the same issue (overheating + wake up issue)

I got the same issue (overheating issue while in sleep mode). However, my problem is that after a few hours in sleep mode, the pulsing light turns solid, then after it wont wake up from the sleep. At the same time, the fans are in full blast as if the cpu is at 100% because of overheating. Only solution is to do a hard reboot of the system. This is a brand new mac book pro (3 weeks old). has anyone have the same problem? this has happened to me three times already.

Any suggestions anyone?

Thanks,
