  • Right click the Power Panel icon in the system tray (looks like a battery)
  • Click on Edit/Create Profiles
  • On the left side of the new screen, click on 'Maximum Battery Life'
  • Then on the right side of your screen, click on 'LCD Brightness'
  • You should see 9 levels of brightness. Level 9 is the brightest.
  • You need to click on the Save icon. (Looks like a disk at top left of screen)
  • Close the window after you save the changes made.
  • You must restart the notebook in order for the changes to take effect.
