Hey, I can help with this!

laptop batteries die REALLY quickly if you overcharge them for a long time, so, that probably explains why the battery dies after 20 minutes, no idea why acpi isn't being updated with the battery status, however.
what chipset does your sound/wireless use? Not the connection, we know it's pcmcia, but what chipset? If you don't know, then just list the brand names.
