Re: Lenovo C50 - black screen after Windows updated

I have the exact same problem on my Lenovo C50-30 purchased in July 2015.  After a big Windows patch was applied the night before, I was greeted the next morning with black screen and LENOVO logo in the middle (no cursor or animation).  Rebooted many times but same outcome.  Keyboard works, I can get into bios but that's it.  The suggested fix (above) requires booting into safe mode but can't do that on this side. 

 

Found this suggestion to disable the 'Lenovo Service Engine' ...
https://support.lenovo.com/ro/en/troubleshoot/LPT000285?firstpdt=LPT000284

 

... which miraculously returned my Lenovo to resume the prior patch update process where I remember it seemed stuck last before I went to sleep.  "Working on updates 75% ... Don't turn off your PC...." ... in just a few minutes, it's already at "84%" ... Went for a walk, it was done when I came back.  

 

Windows 10 update completed!

 

Next I wonder if I need to turn Lenovo Service Engine back on?
