I have a 2007 era MBP and recently replaced the original battery with one I purchased from the Apple store. Since I performed the replacement, as soon as I unplug the power cord (mag safe side from the MBP) the computer immediately goes into sleep mode. I try "waking" it up and it does, but only for about 5 seconds, and then it's back to sleep. I checked my settings and for battery use it is set on 3 hours fro sleep (screen and system). Can anyone give me an idea about why this occurs, and how to remediate it? Thanks.

    Hi Michael

    could be you have a faulty battery, or it's not being charged or isn't connecting properly, somehow...

    if you still have the old one - does that work as expected ?
    do try resetting the smc - http://support.apple.com/kb/HT3964?viewlocale=en_US

    andyBall_uk suggested the battery might be faulty which is my first thought. Turn your computer over (with the lid shut!) and click on the little button next to the lights. The little lights indicate how much of a charge your battery has - the more lights that are on the greater the charge. If there are no lights blinking the battery isn't charged. Also if your battery is charging, the charger's magnetic plug should glow amber - green means it is charged. If the batter is charged then you might need to recalibrate the battery.

    battery calibration information - The problem is, since your computer immediately goes to sleep when you unplug it, getting the computer to totally discharge is going to take a while! It is sleeping right? Not turning off?

    Reset System Management System You might want to give this a try - it can't hurt. Your problem isn't specifically mentioned but it is a power oddity and that's what resetting the SMC can fix.

    Be sure to report back when this is resolved - I've never come across this particular problem in all my years of owning and supporting Mac notebooks. I want to add it to my tech notebook.
