When unpluged from power souce the screen goes bright again.

Right click on the battery icon in the taskbar, go to Power Options or something similiar. Change the plan settings for the power plan you're currently in. Check the brightness ratio for both battery and plugged in mode. This problem might come if you or someone had tinkered with the settings.

It doesn't make sense when the laptop is pluged into the ac adapter the screen goes dim... If I UNPLUG it from the ac adapter it goes bright again.
This happened once before after we had a power serge I don't remember how I corrected it..... Before I went to work it was fine, when I came home, we had a power serge during the day, I turned on the computer and it was dim while it was pluged into the AC adapter and bright when unpluged........
I took the battery out and the screen went bright again....... Yeah.... Thank you..........
Why when it's on battery power it's bright and when it's on AC power direct without the battery it's bright but when the battery is connected and the AC is plugged in it went dim..... Could something have happened from the power surge?
Is my battery still good?
Thank you for your help.........
Plug your ac adaptor in only without the battery and if the screen is still dim then go ahead and hold down the FN key and then as your holding down that key look for the key that has a picture of a light there will be two of them, one to make the screen brighter and another to make the screen dimmer. Try one of them and see if the screen becomes brighter and if it does, try the other key and see if it becomes dimmer. This will let you know that the brightness control is working thru the keyboard.
explain further, normally when a laptop is connected to a ac adaptor the screen is brighter. When its only connected to a battery the screen is dim unless you manually up the brightness on it.
