User blog:ILYx3/O O I need help

HEY GUYS. It's been a while since i made my last blog.

So anyways I got some problems regarding to my new laptop i just got. (My laptop'd brand is HP, FYI)

Anyways for some reason, my f2 and f4 buttons aren't working in game. Like whenever i wanted to type in public/whisper/clan chat, it doesn't work. When i press the f2/f4 buttons, it increases my screen brightness instead. It's getting REALLY annoying because i can't talk in game and no access to clan chat. Does anyone know how to fix this?

Also whenever i go through the vents (Overdose), everything suddenly becomes dark. And i couldn't see. Same thing happens when i come into contact with the fire grenade.

This is really frustrating, and i need help on how to solve.

thanks, heres a cookie
