I contacted with Lenovo support over Twitter, and they told me that there is
no way to update
Lenovo ThinkPad T460’s BIOS. So, here is a guide that you
can update the BIOS — but with a disclaimer; please make sure that you
know what you are doing because you can do something wrong. Also, I use
Ubuntu 18.04, and the BIOS version was 1.10 which was released March 23, 2016.
The screenshot was taken on 2 October, 2018
Required tools and steps to apply the update
I got an USB driver, and wiped it to make it ready the drive. At the same time,
I downloaded the update, BIOS, from
Lenovo’s support. Also,
wanted to read the
README.txt because they can add important information for
the hardware owners.
Next step is that downloading some utilities to work with that
since we won’t able to flash that ISO into the USB drive.
Psst. I think you don’t run Ubuntu. That’s why you consider some other options to use that tool. Here is the source code
sudo apt install -y genisoimage
As a sysadmin advice, keep the ISO image on your archive. You may need it for latter. Trust me.
Convert the ISO (CD image) to IMG (aka. floppy disk format)
geteltorito -o bios.img r06uj66d.iso
Flash the USB. If you don’t know how to find your USB’s device path, please search it.
sudo dd if=bios.img of=/dev/sdb
So, yeah. We have some todos like applying the update. Don’t unplug the USB, and safely reboot the system. When you see the vendor logo, press F12 then choose the USB driver to boot.
Now, you can see some weird things, so no worry. It’ll be so easy, and it takes only less than 10 minutes; therefore, please follow each instructions.
When pops up the BIOS update, go “system update”, and like we said earlier, follow each instructions. The system will reboot itself a few times.
So, I updated to 1.40 from 1.10
