Still having problems with your Macbook Pro coming out of sleep? (Extreme) (Mac OS X 10.5.2 Leopard)

From day one, I've had problems with my MacBook Pro coming out of sleep mode. Over the past year, I've found things that have made it less of a problem, but things have progressively gotten worse. I believe that something is wrong with the latch on my Macbook Pro that is making it think that I have opened the lid. I thought about bitching about it to Apple, but it's not something that is easily reproduced and doesn't always happen. So I found a different, and in my opinion better solution. It is a Terminal command that will disable the wake on lid open setting. After changing this setting, my MacBook Pro doesn't come out of sleep until I press a key or the Power button. *Note: Your computer will continue to go to sleep when you close the lid. That is a different setting.

Here's How:

Open Terminal (Located in your Applications Folder under Utilities.)

type in sudo pmset -a lidwake 0 then press enter.

it will ask you for your password.....type it in and press enter.

Quit from Terminal like you would any other application.

Here is an explanation of the commands we used today:

sudo : Makes you a Super User for a given command. Allows you to modify things that belong to someone else or to the system.

pmset : Power Management Advanced Settings.

-a : Specifies an action.

lidwake : Tells pmset to change the "action" of lidwake.

0 : Sets lidwake to Off.

If you wanted turn lidwake back on, just change the command line to sudo pmset -a lidwake 1

If you want to see what Power Management settings are currently set, just type pmset -g
