Hey! I have an Acer laptop and all of a sudden my keyboard isn't working properly. No matter what I press, a letter 'm' appears and if I hold the key down long enough, the correct letter/function starts showing up. How do I solve this?
My Acer laptop got the same issue. I tried almost all the methods I searched for Acer laptop. Failed until I entered the Microsoft Community at the topic "Keyboard only works in safe mode". Method 2 worked well for me. Device Manager -> View -> Show hidden devices -> Remove any entries that exist for the keyboard and USB category.
