New HP 15.
Upgraded to Windows Ten 2-3 weeks ago.
When updates began being pushed and a restart was required, my laptop would freeze during restart.
I would then power down / up and all is well.
I noticed during restart my wifi lamp would go orange (disconnected) and cycle to blue (connected).
If I powered down / up the same sequence would occur followed by my audio off lamp (orange) illuminating.
Happened every time. Figured it had something to do with an audio driver but I don't have the knowledge to say if it was that or the phase of the moon.
Today I received update KB3081448, went to restart and it actually restarted.
I knew when the speaker button lit I was good.
Just for s&g, I have "restarted" 5 times in about the past 30 minutes successfully.
No idea what the update is or if it's a coincidence however restart now works.
Just throwing this out there for those who may be documenting all this stuff.
