are these some errors you notice?
RELAX.. this is no big problem, you might have just pressed NUMLK or NUM LOCK key sequence by mistake.
In ASUS EEE pc laptops and netbooks, it is the FN + NumLK key sequence.
FN key is in the left bottom area of your keyboard. NumLK is in the top right corner.
Hold them down together to release the number lock and your typing will become fine again!!
