Hi there. While trying to investigate how to boot from a USB device with my Aspire SW5-014, I encountered the claim that this could be done by entering the UEFI, setting an admin password and then simply changing the secure boot option. Having set a password (though I saw no confirmation field), the secure boot remained locked off from changes. A few weeks later I entered the UEFI to remove the password I had left, and found it would not work. Weirdly, the password prompt for UEFI access even shows less character asterisks than the length of the pass I remember setting.
Does anyone know if there is any way to reset the UEFI pass from outside the bios? I have had it suggested to me by one IT shop that it might be possible given a backdoor passphrase which some manufacturer's build into their bios configurations. Similarly, he seemed to think that reinstalling or upgrading the UEFi would require the password too, and that a battery wipe would not work on a hybrid (though I noticed the battery can be reset using the rest pinhole at the side of the tablet body).
Any help appreciated.
