I've got only Ubuntu 20.04 installed on Acer Aspire 5 and I want to update my UEFI (currently v1.11) 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 (3 years ever since and I've literally tried any proposed solution).
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 definitely don't have enough time to modify partitions and dual-boot Win10 just for updating the firmware.
I've got the latest .exe UEFI update in a formatted FAT32 USB stick but it would NOT appear in both grub/UEFI settings. I've also read that with uefi version it could be possible to update just by copying and pasting the executable file into /boot/efi/EFI , rebooting and selecting the proper boot from grub. Nevertheless, 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.
Any help is really appreciated!
