oh boy.. I just tried the Fn and F5 thing on my computer and I wont be doing that again, my computer shit itself with that. It started making squealy noise and the screen I usually use, completely went blank and instead switched over to the faulty screen (which most the time doesnt work at all and is all red in colour and if Im using that one, my computer usually wont work. I once unable to use my computer for weeks due to this issue so I dont use that screen). I use a another screen connected to it cause of its own laptop screen being broke. Then it shifted and colour back but was coming up "no signal" on the screen I usually use (something I didnt then know how to fix). Fortunately (that got my heart pounding lol) its came back ok when I turned my computer off (thou I lost everything I was doing and hadnt saved ..sighs.. computers). What this incident did thou make me aware of (cause I was pressing buttons on the separate screen trying to get something other then a blank screen back) .. was I have a button on that second screen with a sun on it.. so maybe I can adust brightness there? (Im not game to touch anything else on my computer right now). I think I'll come back to trying to sort that issue out another day after what just happened. Thanks for the advice thou thou it didnt go as planned.
