Should be fine to just download and install 1.19.2 Bios version.Just download exe file and run from windows.
Hi all, im having a problem similar to the topic below.  [URL] Dell support assist (version 3.5.0) adviced me to update an important bios update, version 1.9.1. When i try to update it just fails, no other errors. I have looked at the download page on the dell page, and saw that there was a bios update version 1.19.2 already!!  Is it possible to immidiatly update to this version? Doesnt this mess up my laptop/user data? I saw a method in the above topic, update through the bios with the bios update.exe on a clean USB-drive.

I hope someone can helps me.  With kind regards,  Florus.
