Kernel 5.3.0.53.110 breaks shutdown

New system build set up to dual boot Win 10 (1909) with Mint 19.3. Seemed to install properly however when I attempt shutdown using the Power icon and shutdown button on screen the system seems to go to suspend or something else as the Mint logo stays centered on the display and the motherboard does not shutdown, lights on and fan running. I have this loaded on an old laptop that is not UEFI with same software edition and it works great. Using sudo shutdown -P now results in logo on screen and the motherboard is still "on", Using sudo shutdown -h now results in no logo on screen however the motherboard is still "on". A physical shutdown using a long hold on the front panel button on the case is required to shutdown. I deleted and rebuilt the SSD with no change in performance. I have Mint 19.3 Cinnamon, version 4.4.8 running 5.3.0-53 Linux kernel. Rebuilt system starting with new GPT partition table initially worked fine. showing same version and kernel. Used software update to bring up to date and now has shutdown issue again. Attempted timeshift from initial install prior to updating software and failed to restart, hung with screen blank and MB on with CPU fan running. Restarted computer with external case restart and shutdown is back working. Now on kernel 5.0.0.32 not 5.3.0.53.110. Installed language and multimedia codecs with no issue, shutdown works. Installed all non kernel updates (118 items) continues to work. Need some help on this one.
