Bug Description
When I'm AC power and I engage my Vostro 1500 after it dims the display for being idle for too long (30 seconds?), it doesn't go back to full brightness. It goes back to one level below full brightness. I think it should return to the full brightness level from which it dimmed. As a workaround, I have to manually readjust my screen to full brightness with either the menubar slider or the keyboard function keys.
Similarly, when I'm running on battery and the screen is at full brightness and I let it sit idle long enough, then I re-engage it, it only comes up to about half brightness. Hmm.
I think in both cases my screen should return to the setting it was on before it went dim.

I can also reproduce this. I don't get full brightness when brightness automatically dims.
On top of that, in the "Reduce backlight brightness when on battery" option, if I swap to battery and later to AC, it happens the same. This can be a problem, as described in this situation (numbers are approximate):
1- AC power (100% brightness)
2- Battery (75%)
3- AC power (85%)
4- Battery (60%)
5- AC power (75%)
6- Battery (45%)
[...]
Until screen loses all its brightness.
I suppose the same behaviour could happen with the "Dim display when idle" issue.
