Maybe you hit the brightness down, key combo, while on 120 volts.
Where is a brightness down key?
Laptop is HP G6234.
Battery charges up to 100% as long as cord is plugged in. Bright on battery as long as battery stays up, which isn't very long, then will charge back up when cord is plugged in. Screen shows "Plugged in, charging".
Screen goes dark as soon as cord is plugged in.
Power is set to "HP Recommended" as it has always been. Other option is Power Saver but hasn't been used.
