why does my screen get darker when i am charging my battery?

[jelmac]

This morning while using my HP Pavilion Entertainment PC I needed to charge the battery and when  plugged it if the screen dimmed. I will light up when I unplug it but goes dim again when I recharge. Any suggestions?

That is odd.Usually the screen dims when you unplug the power cord to save battery life. Check your Power Options in Control Panel to see how it is set for screen brightness on battery and power.

I took off my laptop's battery keeping plugged in the adaptor/charger.from then my laptop's display becomes dark when plugged in or plugged out the adaptor.how can I solve this problem?

Go to Control Panel/Hardware and Sound/Power Options/Change Settings for Plan (for plan ENERGY STAR). Then move the Adjust Plan Brightness Indicator for 'Plugged In' settings to the right until it is about 3/4 of the way across the line. Then click Save. This should fix the problem and you can play around with the indicators till you get the brightness you want.
