Bought ASUS K52F-BBR5, Screen Flickers. Ideas?

Is this common with all LED screens? Mine does not, although i heard some people who have this model can see theirs flickering (Latitude E6400).

I bought my mom an ASUS K52F-BBR5 from best buy the other week and I noticed it flickering on lower brightness levels (where people claimed they noticed my model flickering) and she (57 year old lady) noticed it as well. I checked to see if any power options were enabled but nothing of the sort was. It's fine on higher brightness settings. care lol.

So...should i exchange it?

Edit: Nm? My mom and sister said they tested various brightnesses and is fine now, so i honestly have no idea if it just needed a break in or something or what. I was pretty sure i still saw flickering after i disabled any possible power saving features but maybe it needed a reboot or something. anyway, they assure me its fine and im in another city, so if it becomes a problem, i'll have to go through ASUS. hey, its not my laptop, its my moms!

thanks!

nevermind!

 

It could be the AC adapter. If it continues, ask ASUS or Best Buy to exchange it for you under warranty.
