Fantastic! I was just having the same problem when I read this article and pressed FN+NumLk(F11), then the keys started to work properly again.

I think for your laptop the number lock key is a second function... Try holding down the function (Fn) key and pressing the F11 key, hopefully that will turn your number lock on/off.

We all have those kinds of days from time to time <Grin>. The best solution that I have found is to smack myself on the forehead and continue on with the day!
Speaking of which,have a super day and keep smiling!

Hi,
You better check first if it is the keyboard on your netbook is the problem.
Below is the steps that you can use:

You need to use external keyboard ( typical keyboard usually use for desktop PC ). plug the external keyboard to the port where you can plug the cord of the external keyboard cord going to your netbook

Then, if the external keyboard will work the best thing to do is to bring your netbook to the support center near in your area to check if the keyboard of the netbook if its still working properly and to find out if you really need to purchase a replacement for the keyboard of your netbook

If the external keyboard will not work you also need to go bring your netbook to the support center to check the parts that is connected in your netbook.
