UEFI firmware is quite complex and abstruse. It is easy for a vendor to get it wrong. As long as Windows seems to run, ship it. I just discovered the Firmware Test Suite <https://wiki.ubuntu.com/FirmwareTestSuite/> It acts as a lint for firmware. It detects some violations of standards (such as ACPI). Although it is a Ubuntu / Canonical project it can run on other Linux systems or even from a stand-alone bootable image. To install it on Fedora: sudo dnf install fwts Probably the only thing you can do with the result is fling it at your vendor. It might also give a consumer insight into the quality of the firmware engineering.
