On my HP ProDesk 600 G1 DM, every time I put the my pc into sleep mode, when woken up by keyboard and/or mouse or Wake on lan, the Windows 10 installation turns on, and then promptly shuts down the system. While suspending using Ubuntu, the issue still persists, but I am presented by a constant black screen and high CPU usage (fan noise ramps up to max). I have not tried reinstall either OS, but since it's persistent across both OSes, I kind of feel like it has to do with something in the BIOS or hardware. (I have tried to solve this issue according to other online forums but nothing worked.)

@CoolestTester41 -- I am presented by a constant black screen and high CPU usage (fan noise ramps up to max)
When most computers are powered-on, the POST (Power On Self Test) is immediately launched -- before you see anything on the monitor. Part of the POST process is to ramp-up the fan(s) to 100% speed, and 100% noise, and then to measure the temperature of the processor & the motherboard. If the temperatures are "normal", then the POST slows-down the fan(s).
So, there seems to be some failure during the POST, and the fans stay at 100%. Sigh.
