I use my 9550 in and out of the TB dock and put it to sleep multiple times a day, by either closing the lid or selecting sleep in the power dialog. This has worked flawlessly for the last ~9 months.
Since the latest win update my laptop now boots each time I open the lid or plug in to the TB dock. I've looked at the power settings and nothing seems to be amiss.
Any suggestions?
thx, Dave

Looks like re-flashing the BIOS has fixed the problem for now. Can't wait for the next windows update...
Latest Win10 update causes 9550 to reboot after sleep
