Re: Laptop Screen dim
Control Panel > Power Options > Adjust the Display Brightness
You should see two settings. One for while on AC, and one for while on Battery.
You should also be able to override using the FN key combo for brightness. On mine, it's FN+F8.
Since it's only 2 months old, you should be under warranty. Don't put off getting it fixed if they will do it for free.
For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth
