How to increase brightness of Tablet when on battery?

[nikemen]

So, when I unplug my tablet from AM, the brightness goes down a couple notches, which I don't like. I find the brigthness at full in some lighting situations, JUST a bit too thin.

Historically, there was a setting in the Thinkpad configuration utility that allowed an OVERIDE to NORMAL brightness settings, which could get the brightness back up to "11" so to say, but I cannot find that in VISTA or anywhere else in the Thinkvantage settings.

Is there still a setting and a way to do that today?

Try the BIOS?

thanks, that is where I had to go to get it switched. Funny, it is no longer available direct through some OS UI
