shutting down problem...

[cambio2]

I have a new in june 2006 white macbook 2.0GHz Intel Core 2 Duo w/ 1gig ram. Since new the mac book occasionally restarts? or goes into sleep mode and drains battery AFTER the macbook has been properly shut down (not logged out or lid closed for sleep.) I will find the macbook w/battery totally drained or when I start it up it says that the OS was improperly shut down. It starts up just fine. I found it in my case heated up and in sleep mode yesterday after once again, properly shutting it down. any clues would be greatly appreciated. thanks

Have you used software update to find the latest software/firmware?

Try going into Disk Utility and pressing 'repair disk permissions', it is a general fix-all. Also try resetting the PRAM and PMU.

How to do these:

1. Turn off your computer and hold the power button until the sleep light flashes, wait for it to stop flashing, it will beep, and then the computer will start.

2. (From Apple)

Resetting PRAM and NVRAM

Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

If you bought the MacBook in June then you have a Rev A MacBook, not a Rev B MacBook with a Core 2 Duo. They were't released until November. That being said, you may be having the issue that the rev A models had.

Like psychofreak said, check to see if in the Software Updater (In the Apple Menu) has any firmware updates. Install any firmware updates that appear.

Are you by chance closing the lid before it shuts down? If you do that, it will go to sleep before it gets a chance to fully shutdown.
