Thank you for that information. Unfortunately this one needs to go in for service.
The repair technician will change out your keyboard portion because they eventually wear out and cause unwanted operation like the problem you have now ;-(
Its not a very expensive repair and you can do a local web search if you want a tech to come out to your home and fix this for you.
Or you can bring it to Best Buy or Sears for this repair.
Both Best Buy and Sears do a great job and they are reasonable but they take up to two weeks to have it back to you fixed.
If you are handy and would like to replace the keyboard section with my help that works too.
Just let me know on that. But you will need to do some soldering more than likely as well. let me also know if you have that experience and equipment ?
In any case, I will stick with you until this is complete.
Please rate my service kindly.
