Update 071509: A reader (thank you Robert) writes to say that although Apple's battery update program has now been officially discontinued, they are still willing to replace a failed battery on a Mac Book that is less than two years old. Products Affected Mac Book (13-inch), Mac Book (13-inch Mid 2007), Mac Book (13-inch Late 2006), Mac Book (13-inch Late 2007), Mac Book (13-inch, Early 2008), Mac Book (13-inch, Early 2009), Mac Book (13-inch, Late 2008).Update 022209: Some people are reporting recently that even though they seem to be experienceing the (see below) Macbook or Macbook Pro battery problem, because it's been more than two years since they purchased their Macbook, Apple is denying replacement batteries.You may continue to use your current battery," The first thing to do is simply shut down, then remove and reinstall the battery.If the problem persists Apple then recommends you (if you haven't already), upgrade to at least OS 10.4.9.Apple's solution to reset the PMU is wrong however - well, not resetting the PMU, just their instructions: Now I cannot claim to be the genius to have solved this. I am only posting this here again, as it took me a couple of hours to find that video and I thought it might help if I add some more links to it.Update 011411: While for the most part THE Macbook Battery Problem is behind us, much of the info on this page remains valid for those of us with older Macbook and Macbook pros.That seems to be consistent with their original announcement: This program extends repair coverage on the battery for up to two years from the date of purchase of the computer for Intel Core Duo-based Mac Book and Mac Book Pro computers.Apple will continue to evaluate the battery update program and will provide further extensions as needed...
The result of this is that the macbook battery will not charge.
Update 100607: Apple releases Battery Update 1.3 for 15-inch Mac Book Pro only. Do you see an 'X' in the battery icon in your Mac Book Finder menu bar? (If your Mac Book's battery is deformed you should qualify for a replacement, but you'll need to Book an Appointment with an Apple Rep.) Apple has quite a bit of information about the problem on their website. I hope this article will help you solve your Macbook battery problem.
Does your Mac Book battery fail to charge after plugging in to AC power? The first thing to know is that your Mac isn't in any danger. (On or about April 30, 2007) Apple stated, "The factors causing the performance issues do not present a safety risk.
And you get a black X over the battery icon in the menu bar.
The mac however does still power on and run okay if the magsafe power adapter is plugged in. After many an hour searching for a solution to no avail - I have finally managed to fix the issue.
This can be accomplished through Software Update (assuming you're online, under the Apple Software Update). Next thing to try is Battery Update 1.2 which is software that udates the battery's firmware and improves functionality. Battery Update requires at least OS 10.4.8.( 10.4.8 can be found here).
