Yet another MacBook (Pro) battery issue
by Giles Turnbull
Late on Friday, Apple released a software update designed to fix performance of MacBook and MacBook Pro batteries.
But additional statements from Apple since that release have been a little more forthcoming. If the update doesn’t fix your battery, Apple may be willing to send you a free replacement, even if the computer is out of warranty.
The qualifying symptoms of a dead battery are:
- Battery is not recognized causing an "X" to appear in the battery icon in the Finder menu bar.
- Battery will not charge when computer is plugged into AC power.
- Battery exhibits low charge capacity/runtime when using a fully charged battery with a battery cycle count (as shown in System Profiler) of less than 300.
- Battery pack is visibly deformed.
Judging by the reactions in the Apple Forums, a lot of users are very pleased to see the release of this update (although a few have reported problems after installing it). It’s fair to say that battery performance, and stories of warping batteries, have been a problem for Apple for some time now. Some action to remedy the situation is welcome, although some sufferers of swollen batteries might wish it had happened sooner. Don’t forget, though, that there was a previous MacBook Pro battery recall in July last year, so it’s possible that some users will be getting a second replacement battery as a result of this new offer.
Personally speaking, the battery horror stories I kept reading were one of the main factors that stopped me buying a replacement portable computer earlier this year.
Recalled battery == free new battery. This is a good situation for the majority of people who have normal batteries which do not suffer from the problems others were recalled for. (it's not a 100% failure rate, anyway)
|I just bought a black Macbook from Amazon on April 16th, it arrived the 20th and I've ran it on it's battery a number of times and did not have an issue. I ran software update this weekend and noticed the battery update, I was wondering what that was for. Today's articles filled me in. I must have one of the good batteries.|
I have a MacBook White Laptop Purchased in October 07 today I have had Apple send me two new Batteries. The last one came with 7 cycle count and it is now at 9cycle count. I have had one Apple techs say that anything under 300 count was junk. This last Tech said 7 cycle count was good. My question on this MAC OS X V 10.4.10 PROCESSOR 2.16 CORE 2 DUO just what does this mean: FULL CHARGE 5100, REMAINING CAPACITY 5059 (,AMPERAGE(mA)-831 ?)VOLTAGE (mV) 12361. Why does it show the -831(mA)
