OK just now my laptop fell to the floor (dont ask!) and it neatly landed on the bluetooth transceiver for my keyboard+mouse. Now the mouse+keyboard kinda works on and off if usik-usik the transceiver. Most of the time took 5-10 minutes of usik2 before it works again. I have isolated almost all other possibility and it now boils down to the transceiver.

So the question now is, can I bypass the transceiver and connect directly to the laptop (which has a built in bluetooth)? If can, how?

I'm using Logitech M275 mouse + K345 keyboard combo.
