Thinkpad P40 Yoga update -> now screen is black

Hello, 

 

I used the Lenovo-Tool to automatically check what needs to be updated and followed the recommendations. It was a NVIDIA-Driver update for security reasons and about 10 - 15 other updates. What I noticed late was that there was also a Bios update recommended and selected. However, I tursted in Lenovos automatic update meachnism.

 

The updates ran trough, despite the NVIDIA-Update which was marked by a red cross. Also the Bios update started and mentioned not to turn off the computer. A Dos-Box under my Windows 10 appeared and disappeared and the computer wanted to shut down - which was happening in a normal way. But now the screens were black, the computer was off. After a while, I switched it on again - the fan went on again but nothing happened. 

 

Which means: 

- The screen is black all the time (as if it was broken, no text is displayed)

- External screens, connected via dockingstation or HDMI are black

- Computer did not display anything when connecting a bootable USB-Stick with free DOS

- Interestingly, the computer is warm and the fan sometimes changes its speed.

 

What can I do now? I assume that something went wrong with the BIOS-Update. 

Is there anything I can do on my own? Can this problem be fixed by Lenovo?

 

Thank you for your replies!

 

Best regards
