BIOS update for Lenovo

I need help in understanding if it is possible to do BIOS update from Bigfix for Lenovo T14s and Yoga devices. I need action script for it if anybody has it.

It’s very likely possible; I’ve driven BIOS updates for Dell, HP, and for other Lenovo models.
Do you have a link to the bios flash utility that you want to apply?

Yes, you can … you’ll need to write your own fixlet and associated baseline to do that.

Our typical BIOS update baselines suspend BitLocker, disable BIOS password (to prevent machine from sitting at a BIOS prompt upon reboot), disable any and all security products such as AV, do the BIOS update itself along with a reboot, then resume BitLocker, re-apply BIOS password, and enable security products. That is the flow we have found that works well.

Ok. Actually, i have never created a fixlet for this before . So, I was looking for fixlet or any action script as an example that can help to give a head start.

@JasonWalker Did you get a chance to look at the exe

Negative, the Forum is what I do in my spare time,.and haven’t had much of that the last couple of days.

We have several BIOS update fixlets published over at https://BigFix.me that are worth looking at as a reference though.

Ok. I got really good guidance from the link you shared . Thank you for that. Just one more concern, HOW should i extract the utility exe.

There should be an extract command line listed on the Lenovo download page?

@Aradhana
Check out the Unattended Update section of the readme for this BIOS update from Lenovo

They have an extraction command as well as guidance for Unattended Update.
