When I have my S210 connected to AC, it works as normal. However, when the AC adapter is removed, the screen dims instantly.


The screen re-power up again immediately by simply re-inserting the AC adapter. Why is this so? 


This is just part of the power management by Windows. When on battery, lower the brightness of screen can help saving some battery so it can stay longer for your works.


Anyway, this could be adjusted through the Power Options in the Control Panel.


  1. Access the Power Options through Control Panel
  2. Click on the Change Plan Settings on your selected Plan.
  3. Make sure that the brightness are Equal on both Plugged in and On Battery (see image below)
  4. Then click on Save Changes button.
