Macbook Not Sleeping When Lid Closed?

just got my new aluminum macbook 3 days ago...installed my apps and updated to latest software. did NOT install anything that (supposedly) messes up with the system or battery. all i installed was office 08, adiumx, toast, iwork, etc.

i came from an old 1.33ghz ibook which... when i move from office to home and back... i just close the lid without problems. i just noticed on my new macbook that it makes sounds with the lid closed

yesterday in the office (as i was about to put it in my bag with the lid closed) adium was making sounds as if it couldnt connect and kept trying. earlier (with the lid closed again before coming to work).. it was making another sound but the sound was not distinct.

i always JUST closed the lid on my ibook when i move from home to the office and back and had NO problems.

how do i fix this? i dont want to keep shutting down when i move.

macbook aluminum, Mac OS X (10.5.5)

I just did some testing and I can confirm that Bluetooth MAY (not will) cause the system to wake from sleep even when it is not paired with any devices. This is usually when you close the lid during the Discovery mode when it is scanning for devices. If you have any Bluetooth devices on during Discovery Mode your system will not sleep. I turned off my cell phone (which is the only Bluetooth capable device that is on at the moment) and the Macbook quickly fell asleep. I then waited for 2 minutes which is when Discovery Mode is off, turned my phone back on and right now the Mac is still sleeping.

So, if you leave your Mac's Bluetooth and it's doing discovery mode, it may cause this issue. I would suggest you to leave Bluetooth off before heading off. It will really help your battery consumption and your Macbook's lifespan.

Also, I notice that the Bluetooth module does NOT turn off when you close the lid when it's sleeping so that may be the reason why it is able to wake your Macbook up while sleeping.

Note: this test is in no way scientific as there is no control nor a comparison with older models.

There's a new firmware release to deal with the sleep problem. A quick test indicates it doesn't seem to cure my problem with the USB mouse, but it might work for some of the other sleep problems.
