Same thing applies to Acer Aspire One D270. I have an external Keyboard, and when I apply the Numlock key, it affects the keys on the netbook's (small) keyboard. I thought my keyboard was screwed up because of the external keyboard. Fnct + F11 restores the keys back to normal. Thanks for the hint. I have also now discovered the integrated number pad on the Netbook's (small) keyboard. I didn't know this function was there.
