Use these steps if fwupd does not work to update the firmware from Linux.

This guide was written from the perspective of an Arch Linux user with a T14s Gen 1 on 2024-26-12.

Steps

1. Download the BIOS ISO from your product support site under the BIOS/UEFI section:
   • Product Search
   • Example
2. Convert it to a bootable image: geteltorito.pl -o bios.img <iso path>.
   • AUR Package
   • Ubuntu Package: The command may not have the .pl suffix.
   • A container can be used if your platform does not have access to an equivalent package. Mount a directory containing the ISO in the container using -v.
3. Copy the bios.img file to your USB device:
   • Ventoy
   • Untested: dd if=bios.img of=<block device path> bs=8MB status=progress && sync -f <block device path>.
4. Boot from the USB device and let the BIOS update proceed.
