When I don't have my mac on the adapter, my mac shuts off without warning when the battery drains, and I loose all my work. It used to give me 15 minutes warning or so, so I could save my work.
I hope my fix isn't that short-lived. I haven't yet had the chance to see it working for a second time yet. Meantime, I hope you can find a solution soon.
I rung Apple in Australia today with the same issue (also having the issue where it's not warning me when my battery is low). The woman basically told me to put up with it...
Absolutely pathetic if you ask me, you spend good money on a laptop that doesn't work properly and then the people you bought it off won't fix it...
I experienced this problem as well. The MacBook works flawlessly. But after a year (and a month) sitting on my wife's desk plugged into the wall, I took the MacBook out for a spin at the local cafe'. The battery allowed me to do 3.5 hours of work (MS Word and Safari surfing mostly). Everything was fine until the battery level reached 12%--at which point the computer cut off without warning. Just my luck to have a major meltdown 3 weeks out of warranty!
Anyway, I went home, read this forum entry and downloaded the battery update, charged the battery all the way
and reset the PRAM, etc. Next day, same problem.
I made an appointment with the local Genius Bar. They gave the MacBook a thorough going-over and determined the problem was in the battery itself. I bit the bullet and bought a new battery for $135. Charged it for several hours at home. Then spent the next 4 hours surfing and sending emails on battery power. Low and behold, when the battery reached 10% or so, I received the familiar battery warning. Ahhhhhh... It's not a logic board problem. I think... I've only run the new battery through one cycle.
I've talked to at least two other friends who own MacBooks. They've experienced the same problem. What's incredibly frustrating is that the Mac Genius made it seem as if this was the problem of it's kind he's seen with MacBook batteries.

The SMC/PMU reset doesn't work for me neither, I have called Apple twice and they say they can't exchange it. So since there is no Apple store near me I have to go to some service provider, what a pain in the butt. I don't see why Apple doesn't acknowledge that there is a problem with these batteries and send out replacements without having to jump through hoops.
The problem had come back again today. So I guess the smc reset only worked for me for like a week. But my battery's life is really good. I got almost 3 hours today before it turned off itself. Do you guys think this shutdown would affect the integrity of the system? I am tempted to do a recover of the system. And I just have to be really careful the next time when the battery goes below 20%. I won't take any chances again.
I did NOT have this problem UNTIL installing "battery update 1.2"! It's clearly a bug and Apple NEEDs to fix it!
I happens when running from battery and "remaining time" drops just below an hour (everytime). Any load, which causes the time to drop will kill it. If you just let it rest (or just play iTunes), you'll get to the "low battery" warning. But, heavy loads will cause it to shut down w/o warning.
Apple, please fix the bug and some otherwise good batteries.
You shouldn't have had to pay for the new battery. It's my understanding that Apple extended the warranty on MacBook batteries to 2 years if you bought it by a April 2007. I would go back in and see if they'll give you a refund. There's a support page that details what symptoms to look for in the battery, but I can't find it at the moment.
Same issues here. The battery lasts little more than an hour, even without any processor strain; it drains to 70% after a day of
sleeping. Installed all updates available.
The computer also shuts down during sleep on occasion, again while on battery.
I'm having this problem at 45% for my MacBook which is only 1 year old. I called Apple today and they said the battery program is only for AppleCare customers. It does not say that anywhere on the site. What is going on?
I am not an applecare customer and they replaced mine. It clearly states the warranty is extended an extra year. Call again and talk to them again. If they don't help ask to speak to their supervisor. If that doesn't work contact
Hi guys, the same thing happened to me too. I am not lucky as most of you who can just ask apple to replace the battery, since i am in China, Asia. AASP here just told me that my situation is not listed in the battery update plan. So i have to make it out myself, and it looks like that i did it.
Here is my way: you let your battery uncharge until it just to turn off, and then you make your macbook sleep manually. It shall sleep like a baby, and your battery would go on to uncharge to 0%. After the blinking LED is completely off (this may take a long time), you battery should have been totally uncharged. Now you can put the power cord back, and let your battery charge to 6%. Then you can see that the low power warn at 5% and the sleep at 0% have come back.
Hope it's helpful and good luck.
