I ask because at my brightness set at the middle the screen looks too dim. Not sure if it's due to fact that I have a screen protector installed. As soon as I cracked open the box I applied the screen protector before turning it on to avoid getting dust under the screen protector. I suspect it's possibly dumbing down the resolution of the screen. In order for the screen to be at a good brightness I have to adjust the brightness to about 70%. I ask this question because my battery is draining fast on my machine. I had a full charge and using it for about 15 minutes it's already down 82%. Doesn't last close to 6 hours. Just thinking maybe it's due to the brightness I have it set to.
