XPS 9310 Developer Edition with Ubuntu 20.04 will not fully suspend

I have a brand new 9310 with the latest BIOS 3.03 and with the factory Ubuntu 20.04 ISO from Dell, I haven't installed anything or made any big modification to the system, only the Ubuntu Software Updates.

When I press Suspend, it will Suspend but the bottom of the laptop will always stay WARM, meaning it is not really in Suspend mode, even if I remove the USB-C charger cable and leave it only with battery, it will continue WARM, meaning overtime it will drain the battery super fast.

Is there something I can do to address this problem so the laptop can properly enter into Suspend/Sleep mode.

Thanks
