I remember way back in 2005, the user manual of my iBook G4 mentioned about battery calibration. It said to charge the battery in full, then use it without plugging in power source, until the battery almost completely drained (the computer goes to sleep). Then charge it to full again.
However, I don't see something like that mentioned in the manual in the recent MacBook / MacBook Pro. Do you still do the battery calibration? Do we need that? |

It's not as important any more, but it doesn't hurt. Intel laptops use lithium-ion-polymer batteries, rather than lithium-ion ones, so the behavior is slightly more ideal.

I also heard that if I let the battery drops to almost completely drained, the overall battery life decreases. Is that also the case on lithium-ion polymer batteries?

I've drained the battery on my iBook G4 (from 2004) numerous times.
The battery still has 88% of it's original capacity remaining, according to Coconut Battery. That seems great to me for a three year old battery. No more Twitter. It's Mastodon now. |

My MacBook just shuts itself off without warning!
There was an article on the discussion forums so I have just forced it back to BatteryUpdater 1.2, and am waiting to see if I get a warning. Anyone else seen this problem? OK, I have given up keeping this sig up to date. Lets just say I'm the guy that installs every latest version as soon as its available! |

I did - they replaced the power inverter, no problems since.
(Although mine shut off at 99%!) |

I assume when this is when the battery is very low, but without the 15 min warning, it's hard to keep an eye on it. At the mo it's telling me I have 29mins.

How old is your MacBook, Gargoyle? There were problems with some MBs where they would shut off without a warning due to some problem with a temperature sensor that would suddenly report bogus information. Geniuses at Apple Stores can check that easily and will replace the part (if still under warranty).

I got it shortly after they came out, but I just got my low power warning so it looks like rolling back to BatteryUpdater 1.2 has fixed it.

Is this the type of thing your computer was doing? How do I go about forcing it back to BatteryUpdater 1.2? Thanks |

First, download battery update 1.2 from here
Then in finder, goto <your HD>/System/Library/SystemConfiguration and do a "Get Info" on BatteryUpdater.bundle. If you have 1.3 then it sound like your in the exact same position as I was. If so, drag BatteryUpdater.bundle to the trash and reboot (Don't bother trying to empty the trash, it's still loaded by the OS and won't let you) After you reboot you'll be able to empty the trash and install the 1.2 version from the download. You'll have to reboot again, and then hopefully you'll be sorted. Disclaimer: If you delete the wrong file and hose your system, or it has a fit it's not my fault!

Hey, sounds good I'll have to try that out. Hopefully it goes smoothly.
By the way, did you have the same issue with the battery meter not responding for a while after your computer shut off? |

Don't think I ever tried. If the software in the computer is not working properly then the battery is possibly being run almost 100% flat - so the meter will not show anything.
After a few mins of "rest" which probably involves slight changes in temperature, the chemicals in the battery probably gain a small amount of charge. OK, I have given up keeping this sig up to date. Lets just say I'm the guy that installs every latest version as soon as its available! |
