Screen Brightness

[mentobe]

I have recently been having a problem with screen brightness.  I have a HP Pavilion zv6000 laptop.  When I plug the laptop in, the screen dims and when it is running on the battery, it is much brighter.  I may be crazy, but I swear that it used to be the exact opposite and when plugged in it was much brighter.  Thanks for your help in advance...

That is the opposite of how it should be.

Contact HP support and see what they say.

when your laptop running on battery,  reduce the brightness to the level you want, then plug the ac power in, adjust to brighter.
now check when you use battery , is it brighter or dim, then plug ac power in, is it brighter?

if it is still the same, check the bios setup, it may be have screen brightness setting for battery power and ac power.  (my dell laptop have.)
