Dell BIOS update not working?

11/13/2018 1420 views

I use the Dell Updates section to setup a patch schedule containing a label containing 1 BIOS update and deploy it to one machine (OptiPlex 990).

When I click run now and wait for a bit, it says "completed" in the status. Yet when I check my system BIOS version it is still A18 and not A24, which is what the update was for.

Anything I am missing?

there is currently an issue with the BIOS updater by Dell which is used by KACE.

The workaround is the following:
1. create a smart label for all devices of one model and the minimum version which can update to this version and less the version you want to update to.
Smart label, so all updated machines go out of the label and you don't need to take care of it anymore, just delete the label when it is empty or recycle for the nest update
2. Download the BIOS update from the Dell Page

3. Create a managed Installation for it. BIOS.EXE /s /f /r /p=YOURSECRETBIOSPASSWORD
    /s installs silently
   /f forces the installation
reboots after the update preparation
   /p provides the BIOS-Password

4. Add the smart label to the MI and let it run. Have nice messages, that the update needs time and the user should not interrupt it and shutdown the PC.

If you have Bitlocker enabled you should disable bitlocker before you update it and reenable it afterwards. In that case a Script would be more effective.

  • Hello thanks for your response. Is this an issue with only Dell BIOS updates or do driver updates require this workaround as well?
    • so far it was only seen with BIOS updates.
