Mac OS X 10.3.9: Battery issues (not measuring charge correctly, etc.): Third-party units affected, more

by CNET staff

Some users are experiencing odd battery behavior (unrecognized, not measuring charge, etc.) after upgrading to Mac OS X 10.3.9.

In particular, third-party batteries appear to be affected more than standard Apple units.

MacFixIt reader Les Clark writes:

"I have a Pismo PowerBook that has be operating with 10.3.x with no problem. On Sunday I updated to 10.3.9 and my Newer Tech 7200mAh battery that I purchased in January has stop being recognized. Nether Apples Battery Monitor or the shareware Slim Battery Monitor can recognize the battery any longer. I have a High Capacity Power Products 4800mAh that was purchased a couple of years ago that is still be recognized and charged by the PowerBook. I still have one of my original Apple Batteries and it is also still being recognized by both software programs. When I installed the update to 10.3.9 the Newer Tech was fully charged and I have not run the computer on Battery since that time. [...] I have tried doing a PMU reset and it did not help. Also the LED lights show the battery to not have any charge."

MacFixIt reader Todd Stubbs adds:

"I set Mac OS X 10.3.9 to install, answered the questions to make sure it was on its way, then went to bed. The next morning my one-month-old 3rd Party battery showed dead. I'm using an old power connection which doesn't have the LED indicators, so I didn't know what was happening, just that it wouldn't charge beyond 1%.

"When I got to work, where I have another power supply WITH the LEDs I could see what was going on. If shut down, then lifted the keyboard of my PowerBook and reset the Power circuits, it would recharge for 3 - 5% then stall. All day long, as I've had time, I've done this to coax it to, currently 70% (It just stalled again. One way I can tell is it reverts to "Calculating" where minutes before it gave a number).

"I have no idea what will happen if I just, unplug it and let it run down to 0% again. Will it let me get it back up to where it was, or will I have to coax it 3 - 5% at a time? Or will it think I only have 3 -5% total power and go to sleep in a few minutes?"

So, it appears in Todd's case that resetting his portable's PMU (power management unit) temporarily resolved the issue.

    I bought a new third party battery for my Ti800 Powerbook 1 month ago. The battery was working great under 10.3.8. After upgrading to 10.3.9, the battery would only charge about 3-5% and then go to a trickle charge. I did the usual reset of the PMU and NVRAM with no effect. I found that removing/re-inserting the battery on a running system will trigger it to start charging for another 3-5% again. To get my battery to 100%, I just keep removing/re-inserting the battery each time it changes to a trickle charge (green LED on charger plug). It took a long time, but I've been able to get the battery to 100% this way.

    This is very annoying and I hope that Tiger will fix this issue.

    I have an 12" PowerBook G4 1.33GHz that exhibiting an more odd behavior that with one battery from another system it charges from 7% to 100% no problem but with an new battery directly from Apple as replacement I get only to charge to 45% and it stops charging. This replacement battery from Apple was an replace the battery that I have worst troubles over. That first battery only charges to 30% but if I use it won't charge to at least the previous level. I have PMU reset and other stuff before I contacted Apple for an replacment.
    This 12" PowerBook has been sent to Apple for service and they replaced the logic board and DC convert once two months ago. I have seven 12" PowerBooks and this is the only one that exhibits this odd behavior.

    My 2-year old PB battery (TiBook 667 Gigabit Ethernet from 2001) is also
    refusing to accept a charge since 10.3.9. I've tried reinstalling Panther, resetting
    the PRAM (3 chimes), PMU, and the NVRAM via OpenFirmware, and finally a
    upgrade to
    Tiger - all with no luck.

    The next step is a clean install of Tiger, but my hopes aren't high.

    I started having the same battery charge problem after upgrading to 10.3.9,
    but only after I had changed my Energy Saver settings as well. I had
    previously had them set to put the computer & display to sleep after 15
    minutes, then changed that to never. It was at this point that I started having
    the battery charge issues.

    After changing the Energy Saver settings back to sleep after 15 minutes, the
    battery is charging again.
