Answers :

The computer's power management system automatically dims the screen when using battery power, which is one of the power-saving features.
\015\012To adjust the brightness:

    \015\012
  • Hold down the Fn Key located at bottom left of your keyboard next to the Ctrl key, and adjust the screen brightness using the left/right arrow keys located at the bottom right of the keyboard.

\015\012A dim or dark screen does not necessarily mean a bad inverter! It could be a faulty lcd backlight bulb, inverter cable, inverter, or in some cases a motherboard failure. If your still under warranty then I would get Acer support on the phone and see what they can do.
\015\012An Inverter converts direct current (DC) to alternating current (AC).
