Dell Inspiron 15 7000 Gaming (7567) Windows 10 Professional -

Has anyone experienced the following issue?

Running on battery only, battery at 95%, screen goes dark and laptop appears to go to sleep.
Close lid, open lid, laptop wakes up and presents the login screen.  However, all alphanumeric keys are not responding so cannot type in login pin or password.  However, mouse still working and "Enter" keys still work.

There is no way to login. Even clicking on the shutdown icon doesn't work. Have to physically press the power button to shutdown and then power on again.
