Comment 28 for bug 1766076

I had to downgrade the BIOS back to 1.10.1 (fwupdmgr installed 1.11) as under the new firmware suspend to RAM caused the system to completely power off (i.e. boot from scratch when powering on). I'll try to update again when the new update is released on Dell's website (the current version on the website is 1.10.1, so I can't even report an bug about the firmware update).

But I doubt this issue will be resolved by a firmware update - as mentioned in my previous comment, this bug has survived numerous firmware update: the original bug report was using BIOS 1.7 and it still happens in 1.10.1.
