since the last update, my yoga 260 no longer wakes up from standby. I suspect that it has to do with the update of the Intel (R) Management Engine Interface V220.127.116.1125. When I try to update this, I always get the error: "Intel(R) Management Engine Interface is not installed in the system"
Maybe it could also be the new Bios (N1GET84W 1.63) if I try a downgrade to version of the laptop does not restart but is stuck in sleep. After a hard reset I get the message: "Secure Flash Authentication failed"
Flash BIOS Updating by End-Users is enabled
Secure RollBack Prevention is disabled
kann mir jemand helfen?

Can you see the "Intel Management Engine" in Device Manager > System devices?
I am asking as I have your same problem (does not wake up from sleep) and I dont have the Intel Management Engine in System devices. I tried to install it downloading from Lenovo website but it fails.
