One major issue I had with my nice new laptop was that for some weird reason I could not hook up an external monitor via HDMI. After searching around everywhere for a solution, this is what worked for me:
$ sudo fwupdmgr get-updates $ sudo fwupdmgr update
During the BIOS update, your computer will be rebooted twice. In total it takes about ten minutes to complete. Be patient, the wait is worth it. Enjoy!
