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...
