These instructions are for System76 owners who have been prompted for a firmware update. Firmware updates may be issued to fix security vulnerabilities or to improve hardware functionality.
Make sure the laptop is plugged into the AC Adapter as USB Type-C charging is not supported for the entire firmware updating process.
Disconnect external devices, including any displays or USB devices.
Take a picture of these instructions or pull up s76.co/sfu on a phone or other device for reference.
During the firmware updating process, the system will restart several times. Prompts will occasionally ask for user involvement.
The following commands can be used to schedule the firmware update for the next reboot and then reboot the system:
sudo system76-firmware-cli schedule sudo reboot
Your system firmware can be updated using a live disk when running on another Linux based OS. First a live disk will need to be created using one of our following articles:
Once the system is booted from the live disk by plugging in the disk, reboot the laptop and hold the F7 key, if it’s a desktop it is F12. The brand name of the flash drive used will be show on that list and can be selected with the arrow keys and then press Enter.
Next open a terminal with + T or on Ubuntu with Ctrl + Alt + T. Now enter this command to list the partition layout for your installed OS:
Now depending on the partition layout these commands will change. The EFI partition is around 512MB in size but may be smaller and it is usually the first partition on the drive.
sudo apt install system76-driver sudo mkdir -p /boot/efi sudo mount /dev/nvme0n1p1 /boot/efi gnome-control-center firmware
sudo apt install system76-driver sudo mkdir -p /boot/efi sudo mount /dev/sda1 /boot/efi gnome-control-center firmware
After the above commands are ran depending on the drive that the OS is installed on you can use the above instructions to update your firmware.
If you’re receiving the firmware update notification after a firmware update, then your system’s Intel ME may be turned on. Let’s reboot the laptop and hold F2 to get to the BIOS. Then go to Advanced -> Advanced Chipset Control and make sure that the ME is disabled, then go to the Exit tab and save. That should stop the notifications about a firmware update and you’re all set.
