It's a wear and tear device. Replace it.

They are $20 shipped from sites like EBay.

I have the same problem. Click the Windows start button. At the bottom is a Windows Serach box. Type 'keyboard'. A virtual keyboard appears. Click the NumLock key on the Virtual Keyboard. This should override the issue you are having and your keyboard and keys should now work. Otherwise reboot!

its better to use pointer as a shift key
this will solve ur problem and make ur work easy
suppose if you disable pointer key it may cause disturbance or difficulty while typing email or doing some other thing
thank u....................

You could get HP Notebook Media Docking Station

I would say it would be best to just replace the whole keyboard. It's not hard, just time-consuming, & you can get a good price for one on eBay.
