I recently switched from arch-linux (antergos) to ubuntu, because I had some Issues I could not get hold on. One Issue was that on everyboot the BIOS notified "Configuration changed. Restarting the system", after which it restarts with resetted settings. On Antergos I could fix this by adding this kernel parameter: acpi_enforce_resources=lax

Now on Ubuntu 17.10 I have exactly the same problem but the kernel parameter does not do its job.

Im operating a Lenovo Thinkpad Yoga S1 and already changed the CMOS Battery. As configuring the kernel on the other OS I do not think that it's a hardware related issue.

Any suggestions?

  • I can confirm that I have the same issue with an identical setup: 17.10 and a Lenovo Thinkpad Yoga S1. – Johan Larsson Jan 28 '18 at 11:09

If you cannot save the BIOS settings in Lenovo laptop, most probably you are impacted with the recent bug in Ubuntu 17.10.

Basically, several Lenovo and some Ace devices have troubles changing the BIOS settings. The issue is critical and Canonical has temporarily removed Ubuntu 17.10 ISO downloads.


The only way to solve the ubuntu bios bug is to replace the Bios chip on the motherboard as seen in this video https://youtu.be/iiFHhEqluCY
