I had your exact same problem after updating to version 8MCN52WW. I reverted it back to 8MCN45WW.

Same problem here too. Moreover, I can't put my device to sleep or hibernate, only shut down! Very frustrating. I will try the zip that you posted to revert.

 

Edit: I get an error message telling me that "this is not a newer version" Smiley Sad What do I do?

 

Edit 2: I enabled an option in UEFI settings that allows rollback and I installed the previous bios version. BUT my problem with hibernation and sleep is not solved Smiley Frustrated

In order to downgrade it, you must enter the BIOS (by rapidly press F2 as soon as you power on your laptop) and you have to change "BIOS Back Flash" value to Enabled. Then save change and exit.
Disable also "Automatic critical update" from Lenovo Vantage.
Hope this helps.

Yes that is the option I mentioned above. But why enter bios that way, it's frustrating, I prefer through windows Smiley Wink
