• Answer:

  Hi, (this is for Vista or Windows 7) Go click on your battery in the bottom right corner and press adjust screen brightness. (It will bring up some power plans Power Saving mode, Balanced, High performance.) Click on the "Change Plan Settings" for the mode you are using and "Adjust Plan Brightness" for "On Battery" and "Plugged In" at the same level. Then it will not change when you plug it in :) If you want, you can also set same brightness for other power plans, so that it doesn't change either. For the second part, you probably have a poor connection from the power input or charger. You can likely buy a new charger online. Hope this helps :)
