I've been monitoring this thread for a while hoping to find an answer but too lazy to register to chime in with "me too". I have to assume several others are doing the same... with the same problem... on ~ the same date.... way to many similarities to be a coincidence.
I've tried the bios update, the nvidia driver update (as well as a few other updates the notoriously bad HP chat support suggested)... all to no avail
Unfortunately no recommendations from me... just wanted to let everyone know that there's at least one more person out there with the EXACT same problem!
