spontaneous shut down

WOOHOO! I'm not the only one! I also have a Core Duo MBP, and very recently, my computer has been shutting off without warning anywhere from 30-50% charge remaining. No warning, no sleeping, just dies. I suspect it is software. Tomorrow I'll be testing my sister's MBP battery- she is running Tiger... we will swap batteries and see what happens. I'm guessing she'll have no problem with mine and using her battery, I'll get random shutdown. Has to be the security update or the "software update."

I just called in to Apple support and they seem to be aware of the situation. I gave the guy the serial numbers and charge and cycle stats. They're sending a new battery under warranty. Mine was not one of the ones included in that original recall sometime back, but it looks like they have another bad batch that they are replacing.

Please post if this works for you. I'm leery of doing this since I'm being sent a new battery. I'll wait to see how that works. If this is some kind of software/updater issue hopefully it will be dealt with in an official manner soon.

I have tried and it does not work for me.

I noticed this first this summer well before I upgraded to Leopard. When I am running MBP on full battery and using iPhoto specifically, I can work for about 15 min and then screen goes black MBP shuts down. Absolutely no warning. It happened to me 3 times before I got it and stopped working in iPhoto w/o being plugged in. Last nite it happened again but this time I looked at the battery level after plugging in and rebooting. I was at 85% capacity. That is insane. 85% .. so I suspected it was not just a battery issue, it seems to be an apps issue as well. I am glad to read Apple knows this and is willing to replace batteries at no charge. I will be calling them after the New Year.

I also have noticed that I have had more 'crashes' with apps since upgrading to Leopard than I ever had in all the years I have had a Mac .. regardless of the OS .. anyone else?

After installing Leopard last week I encountered the same problem with my MacBook Pro. It started shutting down at 24% of battery life.

I sure hope Apple fixes this quickly.

Thank you for your help.

Could go on and on. Does your computer feel overheated? Are you in one format for a while and, for example, manipulating data and it fails more and more the hotter it gets? My Apple has had power downs as long as the night. with or without cord, new batters (own 4), new cords, service. Per Apple Techs at store: "Gotta Catch it in the Act." Good luck. Mine was in iPhoto and I added new iLife and the changes had kinks which I believe was part of problem, heating was another. It's in for service, again.

This thread is just going to go on and on. We all know there is a problem. I will be ringing apple to see if they will give me a new battery. My problem started before I installed Leopard.
is there anyone reading this with the same problems who apple have refused a new battrey?
I am sure apple are working on a solution and it will be fixed. If any one really thinks they do not care about issues like this then either go back to or switch to windows!
every one ring apple get anew battery and let's see what happens

Well, I tried it, and there was some improvement:

- Now the battery seems to drain to a lower level, and goes into hibernation, instead of a complete shutodwn.

But still no OS X warning 😟

BTW this is my second battery - the first stopped charging completely.

Does anyone know if this is true even if your battery is above 300 cycles? I am in a similar situation: first battery was replaced under recall; now the second battery is performing terribly -- first I had shorter usage, then the capacity dropped to about 25%, now I am getting random shutdowns even when the battery is supposedly at 80%.

Will they still give a free replacement at 400+ cycles?

Also, if I do have to buy a new one, am I better off getting the Apple battery or the FastMac battery? Does anybody on this forum have any experience with the FastMac battery?

I got my computer for Christmas it worked just fine until Leopard was installed yesterday and now I can't get it to stay on for 30 seconds without it being plugged in. I am going to call and see if the send me a new battery since I have only had it for a week.

same problem here in Spain with one of the first macbook pros. apple changing battery referring to a bad batch but suspect Leopard. funny thing: when going to their webpage to have the new battery sent, found out someone had used my ref. number to get another battery - an apple dealer here? anyhow, they changed a code and get one sent now. hope this solves it.
