Lenovo Keyboard not Working - I think laptop is infected

Recommended Posts


The keypad on my wife's Lenovo 3000 N200 has stopped working. At first it was the keys T, Y and Backspace. After a day or so it spread and the whole keyboard stopped working except for the touch mousepad. The keys just click-click but nothing appears on the screen.


I have run the Malwarebytes Anti-Malware and no infections were found or fixed. I ran the Farbar RST and the logs are attached herewith.


I would appreciate any help that i can get - my wife is desperate for her laptop as she still needs to do work on it (old as it is).

Attached herewith is the image....

Was a bit perplexed on how to follow your instruction as keyboard isnt working. Discovered that it will type a character after keeping the key pressed for 2-3seconds. However, some keys still dont work even when pressed for longer.
