HP EliteBook 840 G5 Notebook PC
Microsoft Windows 10 (64-bit)

During the workday, my laptop popped up with a message that HP was updating my BIOS. I went ahead with it and rebooted when required. After it was done with the multiple reboots it was Bitlockered. I work on a Service Desk and we have had several calls regarding Bitlockered machines since then. I am convinced that the BIOS update I causing the Bitlocker event. How can I tell if a machine received a BIOS update? Are there log files somewhere? Thanks!

Hi:

 

Looking at your notebook's support page, here is the link to the latest BIOS update.  It is very recent.

 

Driver - HP EliteBook 840 G5 Notebook PC | HP® Customer Support

 

Check the System Information app in W10 and see if the notebook was updated to the version listed at the link above (01.19.20).

 

It will probably have a slightly different date (older) than the release date shown on the link.

 

A BIOS update could cause the user to have to enter a Bitlocker key after an update.

 

It happened to me once.

 

Fortunately, I had the key exported to my Microsoft account when I set up the notebook.

 

Then I switched to a local account after I set up the PC.

Hello

 

your notebooks got BIOS update via WindowsUpdate. That shouldn't create issue with bitLocker.

 

if you want to stop BIOS update via WIindowsUpdate, you have to disable "Native OS Firmware Update Service" in BIOS setting.

 

Bye
