My laptop powers down after a few hours even though I told it to sleep

I've been struggling with my Dell laptop running Windows 10.  The machine seems to shutdown overnight or after a few hours even when it's plugged in.

It turns out my machine is hibernating which doesn't actually work right on my machine.  My temporary fix is to extend the Hibernate after value to 5 days, 7200 minutes I used this forum posting as a guide.
