ThinkPad P40 Yoga does not wake up after latest BIOS update

Few months back I got a Lenovo ThinkPad P40, it has been working just fine untill the latest BIOS update from Lenovo Companion (R05ET72W 1.50). 

 

Since I use it for work, it is connected to power all the time. I have disabled Sleep & hibernation when plugged-in. When I leave the workstation, I usually just lock the machine (Win + L), so that I can access the laptop from home. 

 

After the latest BIOS update, when I get back to work in the morning, ThinkPad does not wake up no mater what button I press. Opening the lid, shows a black screen, does not respond to anything. The red light on the "ThinkPad" logo is lit. 

 

All I can do is hold the power button for 5 sec and re-power. This is horrible, as it will sonner or later corrupt my Windows installation.  I've had to do this now 3 days in a row, after the BIOS update. 

 

I've updated all drivers and ran Windows 10 update. The EventViewer shows only this:

"The previous system shutdown at 5:56:01 AM on ‎11/‎5/‎2017 was unexpected."

 

But I ran the force shut-down at 8:30 AM...

Re: ThinkPad P40 Yoga does not wake up after latest BIOS update

any chance you updated to Fall Creators Update or different windows in the process?
can you rollback to previous bios and see if issue goes away?
