Bug Description
Not clear how battery state gets read/reported, so reporting against linux, generically.
On my 2nd gen, C2D macbook, occasionally the battery state will be unreadable and appear to be at 0% charge. This condition persists across reboots. However, if I boot into OS X, the batter state appears as normal, and then, when booting back to Ubuntu, battery state works correctly again.
