Comment 523 for bug 1734147

Ever since I installed Ubuntu 17.10 bete on my Lenovo Thinkpad S540, there was a message on boot and reboot "Configuration changed - restart" and the laptop would reboot. I was still able to boot from USB though and even updated the BIOS from USB. But that didn't solve the problem. Also the latest kernel update did not solve problem.

After following the steps described in this post http://dailylinuxuser.com/2018/01/how-to-fix-your-bios-after-installing-ubuntu-17-10-on-a-lenovo-laptop.html this problem has been solved.

1.Boot into Ubuntu

2.Open a web browser and type the following into the address bar: http://people.canonical.com/~ypwong/lp1734147/linux-image-4.15.0-041500rc6-generic_4.15.0-041500rc6.201712312330+20170103+1_amd64.deb

3.Open a terminal window (press ctrl, alt and T at the same time) or click on activities and type term into the search bar and click the icon that appears.

4.Go to the downloads folder by typing the following command cd ~/Downloads

5.Type the following command to install the package: sudo dpkg -i linux-image-4.15.0-041500rc6-generic_4.15.0-041500rc6.201712312330+20170103+1_amd64.deb

6.If the command completes without error reboot your computer and choose the new kernel. To get the grub menu to appear try pressing and holding the shift key before the Ubuntu logo appears. If the Ubuntu logo appears reboot again and press the escape key before the Ubuntu logo appears. From the grub menu choose the version of Ubuntu with the highest Kernel number. (which should be 4.15.0)

7.Reboot your computer and open your BIOS settings and check to see if you can boot from USB and save BIOS changes. If you can boot from USB and change BIOS settings then you have successfully repaired your computer and you can skip to the last point.

8.If this hasn’t worked reboot your computer and choose the new kernel. Reboot your computer again and choose the new kernel. Now reboot your computer and check your BIOS settings. If your BIOS can be amended and you can boot from USB then you have successfully repaired your computer and you can skip to the last point.

9.Still not working? Don’t panic, open a web browser and type the following into the address bar:
http://people.canonical.com/~ypwong/lp1734147/linux-image-4.15.0-041500rc6-generic_4.15.0-041500rc6.201712312330+clear+debug_amd64.deb

10.Open a terminal window (press CTRL, ALT and T or click activities, type Term into the search bar and click the icon)

11.Go to the downloads folder by typing the following command cd ~/Downloads

12.Type the following command to install the package: sudo dpkg -i http://people.canonical.com/~ypwong/lp1734147/linux-image-4.15.0-041500rc6-generic_4.15.0-041500rc6.201712312330+clear+debug_amd64.deb

13.Wait for the package to install and if it is successful reboot your computer and press either the shift or escape key to bring up the grub menu and choose the new kernel that has appeared.

14.After Ubuntu loads reboot your computer and enter the BIOS settings. If you can change the settings and save them and you can boot from a USB drive then the issue is fixed.

15.Finally remove the packages you installed by typing the following command in a terminal window: sudo dpkg -r linux-image-4.15.0-041500rc6-generic
