I've been scouring the internet for a while and have yet to find an answer to this problem.
Basically, when the computer goes to sleep, upon wake, the blutooth adapter does not reinitialize. It works fine on hibernate, and re-inserting the adaptor fixes the problem but that is a bit of a hassle to keep doing that to continue to use a simple bluetooth mouse.
I've tried both the default windows bluetooth stack aswell as the manufacturers stack, and still get the same issue with both. I am at my wits end trying to figure this out on my own.
