[Lenovo Yoga Book Guides, News, & Discussion] lectricpharaoh:
If you used the .ISO I posted earlier (remember, if you boot it as-is, it will wipe your machine, so backup first), it should have automatically done everything, including entering the key. For some machines that have an OEM version of Windows preinstalled, the key is written to the firmware at manufacture; properly-configured automated installs will use this key, so you do not need to enter it manually. The Yoga Book is one such machine. If you generate an automated install, use '[KEY]' in the 'Product key (Setup)' field. It's down at the bottom of the options; be aware there is another product key field earlier on that must be left blank.

If all of this was done properly, then the only thing I can think of that would prevent the key from working (and thus, having Setup prompt you to enter one manually) is if the Windows version is wrong. I have heard that even some of the 64GB Yoga Books came with Win10 Pro instead of Home- perhaps this is case for you?

That's odd. I've never noticed this particular issue. Do you mean regular sleep, or hibernation? These are the power settings I use:

Spoiler content hidden.

As you can see, the only time the machine goes to sleep is when I explicitly tell it to, and I don't have difficulty waking it.

I'm not sure that the wifi is the issue. I think it's more likely to be buggy power handling by either Windows or Lenovo. Try this: open an elevated command/PowerShell prompt, and type

powercfg /availablesleepstates

and see what result you get. For me, the only ones supported are Standby (S0 Low Power Idle), Hibernate, and Fast Startup (which is essentially a variation of hibernation).

Did you use my autoinstall .ISO I posted previously? You could try that and see if you still have the issue. I am planning on making another that will include the latest cumulative update, but if you are rolling your own, it's probably quicker to just use NTLite to apply the updates, since you'll have presumably already downloaded the stock .ISO. If you do this, you should know there's one update (KB5000862) that seems to show up twice for some reason, and even after it's installed, it still shows up in the update list. I have no idea why it does this, so I just moved on after applying the small updates, applied changes, and then applied the big-ass cumulative update, so this might be what you need to do if you go this route.

You could also try disabling sleep mode altogether; I usually don't use it myself. It seems like it's far too easy for this thing to turn itself on; if I'm putting it in my bag or something, I'll hibernate or shutdown so an errant power button press won't cause my battery to die. Plus, sometimes the capacitive Halo surface and the screen interact if the device wakes up. I've noticed this on my Android device (I have both versions) when I've opened it up to find it's detected a bunch of 'random touches' causing it to open apps and send messages like it's possessed. The weirdest was when I got a message from a person in Facebook Messenger, asking if I was on vacation. Closer inspection revealed my Yoga Book had opened Maps, tapped some random area, and sent the coordinates through Messenger to a friend, prompting her to ask her question. It was surreal.

The only other thing that immediately springs to mind is updating the firmware. You should have yoga_book_bios_04wt23ww.exe in the Yoga Book package; alternatively, you can download it from Lenovo's site (this link is in the guide as well).
