I got truly ergonomic keyboard few years ago and I used it a bit until I had to change to more regular keyboard as it was shared computer.
So the keyboard stayed in my "IT closet" for few years and I took it out again and it doesn't seem to work.
The number keys seem to somewhat working but most of the letters won't register at all or register with small delay.
Is there something to be done to the keyboard to kickstart it or is it just dead?
