Playbook keeps dimming and brightening
 

I set the pb to screen dim on batt every 3 minutes, with auto dim off. But it keeps dimming 10 - 15 secs after last touch. Then it brightens back about 10 - 15 secs after that cyclic. Very annoying.
Any ideas?

I experience the same phenomenon with my Playbook. I just wanted you to know that since someone else is also experiencing the same thing, it's quite likely that your particular device is not defective. I thought I'd reassure you of that. Like you, I'd also like to know why our Playbooks are doing this, and what, if anything, can be done to stop it.

Thanks,
Makes me feel a bit better.

My wife's playbook does not do this.
