This ass hat laptop.
 

Anyone know how to change the brightness on a laptop? There isn't a button or anything, and I looked through control panel. It's pissin' me off.

uhh first try charging it, then if it doesent work, every laptop has a Function key it says Fn hold it and on the top buttons there is like a half moon push that

I have a function key but there is no half moon, or sun.
