Could the BIOS or Clover Boot Loader version be the cause of this issue? I recall having full functionality of 10.11.6 before updating to 10.12 then downgrading back to 10.11.6.
I'm sorry, it takes me some time to thoroughly understand how to identify and fix an issue. I did use the El Capitan bootpack and I've checked the "config.plist", but couldn't find the values mentioned above. Do you mind guiding me to the correct bootpack? The system did boot before an automatic App Store update took place.
My CPU usage is extremely high while connected to AC power, the CPU usage then lowers when I unplug the power adapter from the laptop.
Persistent logs while the AC power adapter is connected:
