It looks like it has a RTL8111H for Ethernet, which is known to be problematic with sleep. My machines don’t go below C3 due runtime power management being disabled for Ethernet, but enabling it causes it to fail to come out of suspend correctly.
This is incorrect.
The UEFI Forum makes specifications freely available at no cost at https://uefi.org/specifications, and membership is free which would then allow you to redistribute and otherwise use the specs. There are many “open specifications” that require either a one-time purchase of a single specification or a subscription for continued access to a set of specifications, that you of course then cannot share. (PCI-SIG requires a company subscription at $4000 a year to access PCIe related specs.)
edk2, the reference implementation used on everything with UEFI, is open source (BSD-2-Clause-Patent) and available on GitHub: https://github.com/tianocore/edk2.
The problem is not that it’s under proprietary control, it’s that every fucking company forks edk2 into proprietary products because the license allows it (because Intel required it).
