Just bought an Acer Swift AI 14 SF14-51 Ultra7. After running all Windows and ACER Software Updates I found out that F-Keys on laptop keyboard are not working. Also FN combinations with F7 F8 and F12 plus alternative function for DEL not working. Connecting an external keyboard or using onscreen keyboard, made everything work just fine.
Internet and AI gave several answers and made me try alot different things. But I did not find a clear statement that a BIOS update from Version 1.10 —> 1.15 will make everything work fine again.
@ACER Support: Please let people know about that issue for example in description of BIOS updates. ACER phone support finaly gave that hint but is not an instant solution.
I hope this will help others.
