Notebook15-r110na Energy Saver: my laptop screen has suddenly started to go black when I need to plug the power adapter

Laptop screen has just started to go black when I need to plug the power adapter to recharge, if I get screen back to normal.  I have not downloaded anything new recently.  I have download the free 10 Windows but that was months ago.  Any help would be appreciated, but please not too technical as I'm not an expert on computers.

Maybe the powerplan battery is changed or not properly configured. You can see the current powerplan thanks the battery status bar icon.
Please check if the powerplan options are correct.
More specific:
Brightness updates when it is plugged into the charger OK?

Also: If the screen goes black, can still use you the shortcut keyboard keys to adjust the brightness?
