Yoga 260 - Does not wake up

[spyk]

Hello,

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 V11.8.50.3425. 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?

Windows 10 Pro 64-Bit

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.

Hi,

I can not see the "Intel Management Engine" in Device Manager. I have now sent the laptop for warranty for repair.

Lucky you. Mine is out of warranty. Would you be kind enough to let me know what Lenovo will say about the origin of the problem?

I have the same issue.  I cannot update my BIOS from 1.42.
