macbook pro shutsdown after removing power cord

i have a core duo 15" macbook pro with 1.5 gb ram and whenever i remove the power cord it automatically shutsdown (battery is 100% full charge). i bought the machine on september and i started to have the same issue after 2 months of use.

i took it to an apple store and they said it is fine and they didnt find any thing wrong with the battery. now its starting to do it again and ive also noticed a slight bulge in the middle of the battery near the check charge button. also, i used the coconut battery app to check its life (not charge) and its down to 75% already and it also says the age of my mac is about 1000 months! (what the?).

i dont want to take it to the store again, so if i call apple support am i likely to swap my battery for a new one? im feeling that all these issues point to a faulty battery and i am entitled to a new one that enables me to use my laptop without the power cord plugged in all the time!

thanks

My 17" MBP has begun to do the same thing. An Apple employee at a store near me described the battery bulge just as you mentioned.

When I called Apple support they suggested I go to an Apple store if convienent, or I could ship it in for service.

Doubtful they'll just ship a new battery to you. Best bet- go back to the store.

I can't offer you a solution, but can only tell you that mine is the same computer and I'm having the identical problem. I bought my MacBook Pro in August 2006. I am online looking for a "fix" from Apple, but there appears to be no mention of this problem--only your post about the issue. We can't be the only ones, can we?

I have not called technical support yet, but intend to do so today.

Wow, my faith in Apple is once again restored. After calling Technical Support, they are admitting to problems with batteries on some models, and they are shipping me a new battery for my MacBook Pro free of charge (I do have AppleCare Protection). Very friendly and courteous telephone support from Michelle, too!

I love my computer (except for that battery problem)!

I do have the same problem exactly.
My MacBook Pro shut down at full charge after I removed the power cord. It wouldn't turn on again even after a PMU-reset.
Curiously when I left it for a night and tried the next morning it worked perfectly fine. But the problem persisted. I called apple support and they sent me to the next store with a case ID. Now it's been in repair for a week but the technician cannot reproduce problem - that is very frustrating.

The problem seems to come up only after working with the MBP for an extended period of time with the power cord plugged in. A wild guess: the battery's internal security-circuitry may be faulty.

I hope this issue is resolved quickly - I became a laughing stock at work after I said I'd pay the high price for an MBP so that I get superior design and reliability and two weeks after the machine is in repair. Very annoying.

Same problem here.

It Just started happening today, I came here looking for help...

Can it be a calendar related bug?

I've noticed that my mbp has sarted to bow inwards as well. The previous two (1 replaced, 1 repurchased due to product defects) I had developed the same physical deformity.

I have the same problem as of today..1/16.

My Macbook Pro 17 has an "x" over the battery icon and the power cable has the green indicater light ..indicating full charge. When I remove the power cable the computer shuts down.

I have reseated the battery and it remains very cool, indicating it is not charging or discharging at all.

It took a week and a half for my MPB to get serviced at the authorized service center; I had to make several phone calls so the techician could reproduce the problem. He thought, it might have something to do with the heat.
I got the MPB back with a new battery - it now works fine.
I am glad that Apple seems to have gotten the problem fixed with the a new line of batteries.

I've got a new (Nov '06) MacBook Pro C2D and about 2 weeks ago my battery would go from a full charge to zero in about 10 minutes. Sometimes more, sometimes less.

I'm typing this on my ole trusty PBG4 Titanium (3rd battery in 4 yrs) while my MBPC2D recharges.

The serial # on the "suspect" battery ends with X0DA.
Besides this little issue, the machine is incredible.

Time to traipse on down to the ole Apple Store.

An update -
I reset the PMU by
Shutting down my MacBook Pro.
Removing the battery.
Holding down the power button for 5 - 10 seconds.

Once I put the battery back in and started the machine, it has been holding a charge whenever I disconnect it from power.

I just took my laptop in after the same problem, and the technician says that it is common and is due to a battery problem. These latest batteries cannot be run down until they're totally empty. Every time that happens, the battery looses more and more juice until it simply cannot hold a charge.

They're ordering in a new battery replacement for free.
