It does a hard drive check then goes to a dark grey screen which remains 
unchanging.  nothing else comes on screen.  Yes the laptop screen is 
working.  The light on the keyboard comes on that says the wireless is 
turned on.  However, the only way to get it to work is to hit the escape 
early, go to the advanced options and click on the the kernel choice 
that has "upstart" behind it, whatever that is, then it come with a 
ramdisk comment, then it brings up my login screen and and I can get 
online.  I have to go through all these manual steps to make it work.  I 
never used to have to do these steps.  I would like it to boot like it 
used to when it was 14.04. Do you have to escape each time you boot your 
machine and use the upstart kernel?

In this case it is from 7:33 AM till noon when I left for lunch and 
turned it off.

No, what it does not do is boot like it did when it was 14.04.  It was 
updated directly to 16.04 via the software updater when it said there 
was an update was available and was done connected online.

It is a HP laptop with only Ubuntu installed on it.
