** Description changed:
- When my HP Mini 110-1000 is running on AC power, screen brightness works
- correctly. However, when I'm running on battery, the following happens
- after about 20 seconds or so of no user activity:
+ When I'm running on battery, the following happens after about 20
+ seconds or so of no user activity:
- First, the screen gets *brighter*--nearly 100% brightness.
- - Second, the keyboard brightness keys are inverted: the brightness up key
decreases brightness and vice versa. However, brightness only varies over a
narrow range which is entirely brighter than the normal brightness for running
on battery.
- - Moving the mouse or hitting a normal key restores brightness to the
expected levels for battery mode and restores the brightness keys to normal
operation. After about 20 seconds of no user input, the bug pops up again.

I'm running Oneiric with kernel 3.0.0-15-generic. I first noticed this
bug upon upgrading to Oneiric, but another bug kept me running a Natty
kernel (2.6.38-10) until recently. Natty kernels didn't exhibit this
bug, so it's a regression. Unfortunately, I'm not running Precise, so I
can't test it.
