Hi, thanks for your answer. The battery problem has been fixed but it was due to the computer being unable to switch between the dedicated graphics card and the in-built graphics card resulting in excess power usage.

I have another problem actually, regarding connecting to my school wifi system. Attached is the link for how to connect to my school wifi via windows 7.

www.nus.edu.sg/.../NUS-WPA2%20Network%20Configuration%20Guide%20for%20Windows%207.pdf

As windows 8 is still a new operating system, they have not come out with the guide for it yet. I am wondering if you are able to help me diagnose the problem. Thank you.
