It's a problem with the capacity signal the battery logic transmits to the bios, not with the actual battery capacity. covering certain pins on the battery will disable that signal, and the battery will run for the expected duration. the same behaviour is present on windows as well. it definitely is a problem ibm should fix soon. it can happen to brand new batteries. greets, t. _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-mobile To unsubscribe, send any mail to "[email protected]"
