z400 keyboard problem - multiple characters appear when certain keys are pressed.

When I press certain keys, multiple characters appear.


when I press the h key I get "h6"

when I press the - I get "  '-  "


And, there are others.  It began one morning with 3 characters appearing when I typed the "x".  since x is the first character of my signon, i had to use the screen touchpad to be able to signon to the computer.


The problem abated but many characters still give me a weird result. Has anyone seen this?  Any ideas on the solution?  I have only had this Laptop 4 months.

hi JWPesante,


Can you try to boot the machine in Safe Mode and observe if the issue persists (this is to isolate any possible software that might be interferrng with the keyboard). If this works fine without the additional keys appearing, perform a clean boot and observe in normal mode.


If you encounter the same problem in Safe Mode then you most likely have a malfunctioning keyboard. I recommend you contact Lenovo and report the issue.
