Thanks for your help. I really appreciate it. The HP forum has a rep or two who basically advise the user to go through all the usual diagnostics, undo this, redo this. Pretty much following a script. Many users there with the same or similar issue. I know they would offer to return for repair/replace however I have seen individuals do that multiple times, perhaps as many as four times with only temporary or zero resolution. Don't really feel like sending back therefore I guess that's just the way it goes. Now if it was something major I would take them up on their warranty. Here's my dream world scenario: HP does a remote login to my system. Along with a fancy tool, they "restart", the pc freezes and the diagnostic tool discovers the problem. I'll still be on the lookout for a magic bullet over the course of time. Can't stand something not working properly even if I don't use that particular feature regularly. Thanks again for your help.
Better late than never. Yesterday several RealTek drivers (HP-related) awaited download / install to my HP-15. Went through that and decided, what the heck, I'll try the restart button. It worked. I let the system come back to life and it worked again. I also have Kubuntu 14.04 (installed weeks after discovering this problem) on the same laptop and restart never worked with it as well. I tried it twice and had success each time. So far so good.

I know this is an old, old post but I searched around and couldn't find reference to what I found, so thought it may help someone else at some point.
I put win10 on an Acer Aspire 5810T, all went well apart from this black freeze screen behaviour if it was restarted, but not from a cold start. On this unit I found that either disabling one of the dual graphics items in Device Manager/Display adapters or changing BIOS, Main, Switchable graphics setting to "discrete" fix the problem.
