If you can reproduce a failing wired keyboard, check what
/var/log/syslog says when it turns off. Use
tail -f /var/log/syslog
to monitor the output continously. There should be some note on what is
going on. A look in the xorg/wayland logs may also help.

someone has some insight into this.
I have a Lenovo ThinkCentre M75s with a AMD® Ryzen 7 PRO 3700 Processor.
I am running Ubuntu 20.04 I am having difficulties with keyboard
devices. Only a wired keyboard works reliably. Lenovo support has been
no help at all.
If I use a USB keyboard, it will work for a while (5-10 minutes) and
then be locked out.
If I try to use a Bluetooth keyboard, it may or may not be discovered.
Even if it is, after a few days of leaving it on, or after a reboot, it
will be disconnected and will not reconnect.
I don't know if the problem is with the USB driver, the Bluetooth
driver, or the Lenovo hardware.
Any help would be appreciated greatly!
You are looking for a wireless connection in either case. The problem
may not be in
your hardware. It is possible that there is an intermittent interference
condition in
your neighborhood. This could be caused by arcing power lines, or
perhaps some
kind of machine being used intermittently in the area. Perhaps you
should get an
extension cable so you can always use a wired connection.
