1809 caused me to reinstall BIOS

I installed 1809 last week as an inplace-upgrade with the media creation tool.
Installation went fine with no Problems, all files are there afterwards.
I found one huge Problem:
Every time i tried to wake the rig from Sleep it did a reboot instead of a wake!
That caused me to search for many hours, what did the reboot.
Finally, i had to reinstall the bios, since then, all ist fine again.
So did the update to 1809 destroy the bios?

Hi, was that actually a BIOS update, or the same version?

It was the same Version, no upgrade available.
