Hi, I've got installed Ubuntu 20.04 standalone and I want to update my UEFI (currently 1.11) because the screen will remain black once I close and open the lid and the only solution is to hard-reboot with the power button. I've read that multiple users managed to solve the problem by updating the firmware. Could you please tell me how to do it from Ubuntu? I've got the latest .exe file in a formatted FAT32 USB stick but it would NOT appear in both grub/UEFI settings. Also I've read somewhere that it could be possible to copy and paste the executable file into /boot/efi/EFI but actually I haven't tried yet cause in that directory I've got three more folders (Boot, OEM, ubuntu) and I don't know which one to choose .
Thanks!
