How do I correct my laptop screen orientation?

I can´t change my brightness display in my laptop?

• My computer seemed to work well just 5 days ago. I would click Fn + The up or down arrows keys to change my brightness. I tried going to Windows Mobility center and Display brightness and Screen orientation were not there. This is really recent and I have checked for viruses and stuff like that. Also, I have a problem where if I close the lid on my laptop so I can carry it while it is on it crashes. It shows the blue screen and says something about my bios or something like that. You see, my built in camera used to work but when I close my lid something weird happens. I believe that my bios or something like that has a problem. At the end I´m just wondering if there is something I can do or if I just should take this with a specialist? (Mi computer is running windows 7 ultimate 32 bits and it is a Lanix, which that is a Mexican brand) Thanks for your time
