Easiest way: open energy options, set hibernate in stead of standby, or always shutdown of course.
I bought exact the same hardware on ebay, and am now screwed, too. Ive sent it to them to repair once, after a fw update crashed it, they claimed to have replaced the mainboard, but it's still not working. I found out to disable the fingerprint reader and oriantation sensor (connected to AMDsensor device) drivers as they are not signed and seem to cause problems.
another clue i found on reapair videos of that model:
-later revisions of the mainbord have the ram installed more on the outside of the board, that means instead of near the inside to the CPU more on the edge of the casing.
Probalby the termal design is so bad, that the ram gets to hot, if fans are turned of in standby. One should really complain about this switching the fan of when in standby, i wrote on this on quora, but no one really knows, if that's a fault of microsoft or lenovo...
If you want do dive deeper, i'm writing here on this reddit:

Try disabling all network activity: (network stays connected anyway)

***win -> CMD:***
``(Disable DC! = battery network use)``
``powercfg /setdcvalueindex scheme_current sub_none F15576E8-98B7-4186-B944-EAFA664402D9 0``
``(Disable AC! network use)``
``powercfg /setacvalueindex scheme_current sub_none F15576E8-98B7-4186-B944-EAFA664402D9 0``
i got a lenovo flex5 with a shity early revision motherboard, so you probably have to look for bad drivers (that are not certified by microsoft) dod this by:
***open win->cmd -> eventvwr.exe and search for bad drivers yourself***
***right click win->hardwaremanager and disable faulty drivers, or update them, play around...***
this is still $@$*!&, cause drivers are updated sometimes by windows or the like... or even sometimes my batterie drains, probably while win is trying to install updates while in standby (what a $@$*!& behaviour when on batterie!) but very seldom.
i assume microsoft wants all manufacturers to sign their drivers, so they can get control of what hardware is used.
probably this would be a good topic to try further stuff:

we should all cry. that there is no 100% solution or workaround (the nework thing is best) and that nobody seems to have a good tool/crack to disable all background activity
