E540 Keyboard produces extra characters

2017-03-02, 18:44 PM

Certain keys on my E540 keyboard will produce the desired character plus an extra character when pressed.  The keys that do this are q,w,e,r,u,i,o and p.  Each one produces a digit in addition to the letter; for example, pressing q produces q1, pressing w produces w2, pressing e produces e3, etc.  This happens only on the built-in keyboard.  An external USB keyboard works fine.


As far as I know the built-in keyboard worked fine for years, then this problem suddenly appeared.  


I've updated the BIOS and all drivers to the most recent versions, and installed all Windows updates. The OS is Windows 7 Professional, 32-bit.  If any one knows of a fix to this problem it would be greatly appreciated.
