Hi there and welcome Carol
I did not see the model from your for youe Laptop but on most models this is when Numlock is enabled.
Hold the FN key and press Numlock
Does this stop it for you?
If not, download this file
Doubleclick and run it and it will turn it off for you.
If you have any problems, or would like any additional information or assistance, please do not hesitate to let me know.
Else if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
