For anyone reading this, I have found a work around. It works for my computer and may work for yours. It doesn't "FIX" the issue, but it makes the computer usable.   All these settings prevent the screen from turning off when plugged in. This prevents the system freeze. It also allows the laptop to hibernate after 5 minutes. Hibernate seems to work, but sleep does not.   Good luck!
Hello to anyone who can help. I have tried many, many different things to resolve this issue.  I have an Inspiron 7373 2 in 1 with an Intel UHD 620 graphics card. If I put the computer to sleep or hibernate, it wakes to a black screen and is unresponsive. If I leave the computer and allow it to turn off the screen, the processor fan starts to rev higher and the computer becomes unresponsive. I have updated the BIOS and the graphics drivers to the most current versions. I have tried older versions of the graphics drivers. I have tried running in Safe mode, I have tried clean booting, I have searched through error codes, and worked with all sorts of settings to resolve the issue. I was able to find a solution, and maybe this will help someone else. I was able to uninstall the Intel Graphics Driver and use the Generic PnP Driver. The computer works beautifully with that driver. No freezes, no hangs, goes to sleep and wakes up, Great! But, I lose my ability to use my HDMI port. So the question, can anyone help me resolve the issue with the Intel UHD 620 graphics card? Or can you help me get my HDMI port working while only using the Generic PnP Driver? I am not opposed to customizing the Generic PnP to allow the HDMI port to work. Thanks in advance.
