Is this how the GPU module cooling will work? (a poor mouse drawing of my best guess based on the pictures)

It takes some work, but it's possible to get to less than 0.5%/battery/hour, a fair benchmark as a battery reduced by >=5% after 10h of sleep is generally acceptable

Do you have links to useful resources??

First please read my windows guide on csdvrx.github.io: it's very generic and should get you a baseline in Windows

Then get at least a week worth of measurements over long periods of sleep (like at night, reboot on windows) as a baseline

Then tell me how it compares to what you get on Linux after enabling everythig with powertop tunables and we'll work from there, as it'll be more precise than powertop.

Just send that by email at my outlook address. Includes the discharge line plot from Windows sleepstudy you find the more relevant, and a dmesg from linux

FYI, without wifi, on my thinkpad recently installed to Arch I measure 3.6W in powertop but I think it needs a recalibration as I measure 2W on a USBC power meter when idling with wifi enabled and a full wayland desktop (edge, etc)

You have been able to configure that behavior (sleep-then-hibernate) on any Linux system that supports S3 for a long time (years and years).

At the same time, Apple now uses a kind of sleep similar to 'Windows Modern Standby'/Intel S0ix: https://macreports.com/why-does-my-mac-get-notifications-whi...

No matter what else they do, the arrow keys tell me they are fools who should not be trusted! (Hyperbole, sure, but only a little.)

However, because I know how to type, I use the right shift key constantly. Of all the keys to fuss about...

Not sure why 99% of laptops see a numpad as a higher priority than matching a desktop keyboard layout.

I wish you spent more effort in fixing it at the software level, whatever it takes.

I currently use a TB3 eGPU case and the massive overhead and OEM bugs are slowly making that real PCIe link worth it.

Otherwise, could flash programming be unlocked to facilitate flashing third-party firmware?

I'd switch to a Framework laptop for the hardware configurability, but not if it means losing Coreboot.

And more importantly, I love what you are doing for the industry overall. The idea that I can swap out my display from glossy to matte on a laptop that I've already owned for a while for less than $200 is pretty amazing. I wish you a lot of success.
