Guys, need some help here

I got a Alienware M15x for around 4 months and just few hours ago I got this problem,

The laptop screen dimming does not revert to previous setting after it dim (dim when away for 15-20 minutes)

So I have to actually manually pressing 'Fn + F4' to increase the brightness.

It gets annoying especially when I am using youtube. It dims whenever I watch something and I have to revert it back manually.
I went to administrative tools > Service > disable AlienFusion and yet problem still occur

Anyway to solve this?
I tried to search around the forum but couldn't find any post or topic related to this.

You mean the power plan settings?
I selected the 'Never' and it should be alright

But the thing is I'm little disappointed since the auto dim doesn't work at all. Not that I want to save power.
Its more like...the feeling of 'there are no way to solve the problem other than switching it off'?

Well anyway thanks

Edited: The power setting doesn't solve the problem. It still dim and I have to set it back manually zzzz

Oh I went to the battery option instead of AlienFusion cause I thought I disable it already
I enable it now and switch the auto dim off. Will see what happen next

Thanks alot !!
