Wer hatte die gleiche Frage?

Hi!

My Akoya E6421 (MD 99952 - MSN 30020563) came with Bios version 2.17.
It seems there is a new version 2.20. I plan to update because I experience some screen problems when the PC awakes from sleep of from a "turn off screen" (all drivers and Windows 10 updated):

• There isn't any "read.me" logging the changes in the new 2.20 Bios version. Could someone tell me what the changes are compared to v. 2.17?
• Are there any specific things to know with regard to the Bios update procedure on this PC?

Thanks in advance!

PS: sorry for writing in English. I posted on the french forum, but there isn't anybody there...
