This problem normally occurs, when you use a USB keyboard and have to enter the system BIOS.
Therefore, you have to use a PS2 keyboard, to get into the BIOS.

Do a full power off of computer and remove ac plug. Press power button a few times. Remove usb keyboard and attach ps/2 (remember ps/2 is not a hot plug device!)

Then power it on with and see if any keyboard lights light up. If so then you should have a way to enter bios. It could be that the keyboard is bad too or some issue with bios.

Hang up and live.

Jefro

you are not right by saying PS/2 is not hot plug.

When I turn on my computer without any keyboard plugged, and then I plug a PS/2 keyboard, pressing Numlock once and the keyboard is available.

Made it hundred times and more.

In my experience, if/when a mouse or keyboard becomes disconnected from the PS/2 port while a machine is running it will not return to operating status just by plugging in again. A reboot was required.
USB is designed for hot swapping. PS/2, Parallel and Serial ports were not and attempting to do so carries a risk of damage to the motherboard.

I guess when I retired from the company that made the ps/2 I missed the point about it being a hot plug. Not it is not a hot plug device. People do it and the fuse was raised and the circuit change to let silly people do it but it was and is not a hot plug device. Only usb and more modern connections are.

Hang up and live.
