When using my 8700c, I noticed that on occassion, the light will dim when I am reading emails or if I am on the home screen, and other times, it stays nice and bright. How do I control this? I have the option on brightness set to 100, but it dims down a little on it's own. Thanks for the help.

Do you have the AUTO brightness option turned on?

If so, turn it off.

i get the same on my 7100, i dont see an auto brightness option anywhere so is there somethng else somewhere.

Look under Options - Screen/Keyboard. On my 8700C the On Off for auto brightness is there.

I know its the wrong section but anyone know if thers any option for this on the 7100 series, as theres no auto brightness under screen / keyboard on it.

Not an option on the 7100 series, only the 8700 at this time.

When it dims, just tap the on/off switch once. That will bring it up to 100%+.
