I finally solved my laptop keypad problem. Some of the keys kept jamming. So in a fit of anger, I tore open my laptop and disconnected the keypad. Now I'm using an external keyboard. Haha.. Everyone please pray for me that the Toshiba Service Centre will change a new keypad for me for
free on Monday when I bring it there.
I've concluded that I'm a very rash person. I will do whatever it takes to fix a problem. And the problem must be fixed immediately otherwise I won't be able to eat/sleep in peace.
