M6300 Screen Funny Issue

Well i can usually fix my laptop problems but this one has me very surprised and i wanted to ask for opinions before doing somehting drastic (like changing the screen)
But alf m laptop screen goes dim, if this were the only thing the anwser would be obvious (broken screen change it) but the thing fixes when it goes into battery and slowly comes back when its conected again
I has virtually the same brightness on battery mode than on conected mode so the only real thing conecting her does its dimming alf the screen.
Why would it work while on battery and not conected? and why only alf screen?
I am about to send this to unsolved mysterys

 

Have you tried lowering the screen brightness? Either the inverter or the backlight has an issue, this doesn't sound like a driver or software issue.

 

Funilly enough yes o.o i lower the brightness and after a while the screen gets brighter? makes no sense i know but its true

 

I *think* this is an inverter issue then...
