Hi,
I use a laptop. When I take the power cable out to run on batteries, the screen darkens, as it is no longer so bright, to save on battery power.
When I put the power cable back in, the screen brightens back to it's original brightness.
However, I have since replaced the power cable, and the screen remains darkened.
How do I regain the original brightness?
Thanks, Steve
