your laptop may have software installed to manage power...check out if there is such a thing running in the tray...it is the case in thinkpad..
but in my thinkpad i m using the power management in the control panel by selecting the laptop scheme.

you can try increasing brightness in AC or battery mode by pressing FN and F8 i think..it could be different for your laptop...check the manual..if one can increase brightness like this then it may not be the display problem

dear speedyguy...
the thing u r facing isnt a problem this is the very primary power saving setting that all laptops have...

though u can brighten the brightness by the dedicated buttons on ur keyboard..
which model u have do post details,..
