Power options problem
Have a Toshiba Satellite L550 i5 8GB RAM 120GB Crucial M4 running Home premium 7 and I am having a problem with the screen going bright on unplugging the power supply and onto battery then reverting back to a dimmer screen when power is plugged back in.
Have tried all the settings in Power Options with no difference in any of the options.
I do notice that usually when one move the brightness control slider for power in say high power settings the brightness of the screen does not change as one moves the slider.
Anyone got any suggestions for cause please as I am thinking maybe my power adaptor is failing.
