First, make sure the battery is at least 30% charged and connected to power. We are then ready to perform a firmware upgrade. Open a Terminal window and enter the below commands:

sudo fwupdmgr clear-offline
fwupdmgr refresh
fwupdmgr update

Reboot the machine and allow for the EC Firmware to apply. Do not interrupt this process, as it may take 1-2 minutes to apply.
