Black screen after boot up

[wmbpbw]

Two days ago I upgraded the OS version to 16.10.Suddenly I got black screen after I start up the Laptop(HP Probook 4530S).

There was only a text file in Desktop and only that file was visible and was able to open it.
The rest was black and unable to take any actions.I was not using new unity and using the default Ubuntu GUI.

I am only using Ubuntu 16.10 as my OS.

After shutting down using power button and restart the OS.After that everything became normal.No issues after that at all.

Is this bug no longer reproducible after a power cycle?
