I'm so sick of this.. Every time I'm doing something - like chatting or posting a post :D , I can't use any of the punctuation marks like - exclamation point , at , number sign , and , asterisk , the two closing parenthesis.. Its so hard.. Even I'm opening my Facebook account I still have to search an AT sign in Google .
But when I tried the number one in saving a progress in VBA [for those who are playing with this], it worked.. I don't want to buy another keyboard because I know my mom wouldn't buy me one.. So , I'm trying to "repair" this old stuff .
PLEASE HELP >>

Have you tried this keyboard in another machine to see if it's an issue with the hardware.
Try swapping it for another as well.

If it is the keyboard that's at fault they are inexpensive and easy to replace.
