Long time lurker, first time poster etc etc.
I was hoping a BIOS update would fix my issue, but I’m stuck:
I picked up an Intel LAPKC71F laptop, i7-11800H and a 3070 fairly cheaply.
Works like a champ, I have dual-booted Win11 and Ubuntu.
Standby, in both OSes though - It sleeps just fine, but refuses to wake. Fans ramp up, even though the power light is ‘breathing’. Will not respond to any input - Only pressing and holding the power button forces it off. Both automatic standby and manual “sleep” have the same issue.
Latest Intel UEFI update applied, twice - Did not resolve the issue. So I started looking into rebadges - The board looks almost identical to the XMG Neo/Pro 15/21 (M21), but very small things are off. I was considering cross-flashing it (having much experience with this, with Clevo and the rebadges) but the small differences bring me concern.
Anybody have any experience with this kind of issue, or should I just put a bounty on an unlock of the Intel BIOS, or a bugfix?

What makes you think a cross-flash will work or even what makes you wonder that there’s an issue to be fixed in bios and there’s a mod to solve it… even worse when it comes to original intel bioses, at least if it’s still hard ones as in past…
Stay put sir…if you care for your asset, check system drivers (usually a great culprit) and test usb external peripheral’s reaction.
If it’s all the same to you…and have experience in dealing with system SPI re-programming/recover, get a spi programmer and cross-flash everything you found out on the way…
Have you at least contacted Intel support team/forums…
Anyway, just my POV, wait for other users.

Thanks! I think you may be right, which is why I was posting - The whole Intel custom UEFI scares me a bit. I’m going to manually update all the drivers from the (slightly outdated) driverpack Intel offers, and see if that seems to resolve it. It just doesn’t make sense to me that Ubuntu has the same sleep issue.
I am pretty familiar with modding, and have a CH341 on hand 
In this point…yes, same behaviour in 2 OS’s… bios settings or a bios issue that needs further investigation form the OEM (Intel).
Or an ME FW issue/configuration… since this has a bit of an impact on the system besides bios, you can manually update it.
EDIT: No… the latest bios KC0051 has already latest one

Yeah, exactly. I’d read a few other sources that said it needed to be flashed twice (likely for ME, exactly) but I’m at a loss beyond that.
Intel’s UEFI only has Deep / S5 options, nothing for normal sleep. I did find some other guides for fixing similar issues with the NUC series, but nothing useful.
