Here is some anectdotical information about my dying battery, just to show what _can_ happen: My max_charge (from /proc/pmy/battery_0) is down to 465; but was down to 225 already before (from an original, brand-new value of between 3000 and 4000). My battery will last, according to its controller, some 30 minutes only. But voltage will still be above 14.0 when 0 charge is indicated. I therefore deactivate pmud, so I don't get the automatic sleep or shutdown happening after the 30 minutes. Anyway, the battery charge will go in a matter of a mnute from 20% to empty.... leaving no time to react after the initial warning. That way, I can run for maybe 2 hours (depending on useage and backlight level) before the battery voltage gets too low. The battery controller actually goes on providing power until the battery voltage drops to 12.5V, which is the end-of-discharge voltage of Li-ion batteries as used in this Powerbook. It would be interesting for pmud to be able to work on battery voltage instead of the time left as indicated by the obviously mislead battery controller...
