I'm on Ubuntu 18.04 with my Lenovo Thinkpad T460s. After an update a couple of weeks ago I did a reboot and I saw something which included the word "EFI" in the top left corner of my screen. Then everything went black and unresponsive.The laptop started system beeps every 5 seconds or so. I had no idea what was going on and tried to push the power button numerous times. I typed on the keyboard. Nothing. I was convinced something was terribly wrong. Nothing worked and since the laptop has a built in battery I could not cut power (probably a good thing in this case). After a couple of minutes the beeping stopped The laptop booted as normal. I had no idea what happened and whatever it was I was not given much forewarning or information. No way to see what it says while that message flashes by up in the screen corner.

I do know that a package with the word "firmware" in it was updated that day, but not exactly which one. I did check my bios and it's very new, from July 2018. I have not had Windows on this machine since I got it 18 months ago. I still wonder what this actually was. Anyone?

Update: I just read this about LVFS: https://www.omgubuntu.co.uk/2018/08/lvfs-lenovo-firmware-updates-linux

Could that be what I experienced?


A BIOS will never ever update itself and will only update when you tell it to do so. At the moment it requires a manual download, setting the download executable and follow the instructions for installing (sometimes you can load it from bios, others tell you to make a bootable medium).

Regarding the article: Lenovo is joining the Linux Vendor Firmware Service, better known as the LVFS. That is still in the future.

Beeps are an indication of hardware failure. Here is a list of hardware errors for Lenovo. But you need to also remember if those beeps are short or long ;)

Most likely linux-firmware and that is "Firmware for Linux kernel drivers".

  • Thank you for answers. I am still wondering why this is showing in my biois settings: "UEFI Bios Date (Year-Month-Day 2018-07-09"? I have not had Windows on this machine since I got it 18 months ago, and I have never attempted to update the bios. Could that date mean something else? – Christian Sep 11 '18 at 14:52
  • There was another bios update today which I installed. I still do not understand how it got installed back in August after I had installed Ubuntu 18.04. I didn't even know about LVFS until a couple of days ago. This is great news for Linux/Thinkpad (and other supported hardware) who, like me, do not dual boot. The update today had a Lenovo logo and progress bar but the same beeps. The one that happened back in August was just a black screen with beeps. – Christian Sep 20 '18 at 14:14
  • I have not seen any automated bios updates. Only kernel modules related to bios but that is not the same ;) So the question now is: did the version number or the date of your BIOS change? – Rinzwind Sep 20 '18 at 14:21
  • Yes it did change. It changed to v 1.37: is.gd/hWFrnb Last week it went to 1.39 but that one I downloaded from the LVFS site. The upgrade from the downloaded image happened in the exaxt same way, but this time it was a progress bar and Lenovo logo but the system beeps were the same. – Christian Sep 24 '18 at 13:28
