Mac Laptop Batteries back from the dead.
I've been having problems with Mac laptop batteries lately. This page had a lot of interesting ideas (which pretty much didn't work for me). The gist of it seems to be:
- Boot into Open Firmware by doing Cmd-Opt-O-F at startup.
- Type reset-nvram
- Type reset-all
- The machine will then reboot and previously bad batteries will now work fine
