Macbook Pro Wakes From Sleep With Lid Closed

[bmcgrath]

I've had this problem. Seems to be only when the power adapter is plugged in.
Also I've noticed that the light on the magsafe goes out when this happens too.... seems quite strange.

I have a possible solution for some of you. In my case, whatever mechanism that detects that the lid of the computer has opening is being extremely sensitive. the wobbly/crappy screen latch problem has always been an issue (until the new unibody laptops, thank god). The computer wakes up because after you close the screen latch, the screen naturally 'raises' a bit as there is a bit of wiggle room for the screen and hence it thinks that you have opened the lid. This leads to battery life loss, overheating, and eventually damage to the computer due to overheating.

2 Solutions:

1) Put rubber feet on the corners of your screen so that the screen stays firmly latched. However, this can be tricky!!! If the rubber feet are too thick, the screen latch will not close. ALSO, you must put some rubber feet on both sides of the camera in the middle and on the corners because if you grab the laptop in the middle (logically), the screen will bend in.

2) (the method i use) The second method is disabling the wake-on-lid-open. Just go to Terminal (Applications->Utilities->Terminal) and type:
"sudo pmset -a lidwake 0" (without the quotes).

I hope this helps.

you are very welcome jomams.

metroid87706, who cares if its 5 months old? If there was a solution posted, I would not have posted my solution in the first place and judging from jomams post, it seems that there are still some people who have this issue.

Same thing here.

My MacBookPro does the same thing. It is not connected to anything at all. It doesn't matter whether it is plugged in or not. It is already set not to have a bluetooth device wake it from sleep.

It happens after I close it and it goes to sleep. Sometime latter I will hear the fan and drive whirring, the Apple logo on top is lit, and the processor is very hot. There is no cursor when I open it and nothing is accessible. The only way I can stop it is to press the power button and shut it down.

I didn't have this happen until I upgraded to Leopard. I have installed all updates.

Any help?

Had this same problem on my uMBP 15. Drove me completely nuts. Genius did a PRAM reset and SMC reset to no avail. Eventually got a logic board replacement which fixed the problem. Good luck.

i think ths is what happened when the other MR posters melted the keyboard in their backpacks

maybe keyboard or Front Row

My MacBook has only recently started having the same problem.
At first I thought it was magnetic interference near the lid (like a nearby speaker). But then it happened today and there are no speakers or magnetic devices or paired wireless devices nearby.

I've also noticed that my screen has a slight imprint of the keyboard buttons as if the screen is pressing against the keyboard when the lid is closed - so I thought maybe the lid wasn't completely shutting. But no matter how many times I try to press the lid shut that doesn't help. Then just for the heck of it, I decided to open Front Row and then exit out of it. Because I often (60% of the time) have my MacBook connected to an external display for Front Row, so I thought perhaps it was confused and thought it was still connected to the external display. And doing that did seem to work. Weird right? Or maybe it was just a coincidence?

10.6.3 problems?

2) (the method i use) The second method is disabling the wake-on-lid-open. Just go to Terminal (Applications->Utilities->Terminal) and type:
"sudo pmset -a lidwake 0" (without the quotes).

I recently have been having problems with the 10.6.3 update. Specifically, awakening from sleep leaves the backlight off. I haven't been able to solve this, but thought it might have to do with my changed lidwake setting?

I wondered if anyone else who had posted in this thread ran into problems with the 10.6.3? I haven't solved the problem yet, but went back and set

sudo pmset -a lidwake 1

enter root password

pmset -b lidwake 0

I've only had problems with it waking while closed while on the battery, so I thought that might help with the times when I was connected to the wall. I don't want to lose the setting altogether though! I figured it would be reset when I reset my PRAM?
