[Bug 1734147] Re: Ubuntu 17.10 corrupting BIOS - many LENOVO laptops models

I think Lenovo does not support Linux as an OS, therefore, they will
claim that it is not their fault. On Lenovo forums, similar issues with
similar BIOS symptoms have been reported since 2016, without any
support. On the other hand, I do not see how Ubuntu devs can actually
revert the current situation, as Ubuntu theoretically has no access to
the BIOS or its code.

In my case, these laptops are used in a private school, and now I am
left stranded with machines that do not function as they should.

Title:
  Ubuntu 17.10 corrupting BIOS - many LENOVO laptops models

Status in grub2 package in Ubuntu:
  Confirmed

Bug description:
  Hi all,

  Basically on Lenovo Y50-70 after installing Ubuntu 17.10, many users
  reported a corrupted BIOS.

  It's not possible to save new settings in BIOS anymore and after
  rebooting, the system starts with the old settings.

  Moreover (and most important) USB booting is not possible anymore
  since USB is not recognized. It's very serious, since our machines do
  not have a CDROM.

  Lenovo forums at the moment are full of topics regading this issue.

  For example:

  https://forums.lenovo.com/t5/Lenovo-P-Y-and-Z-series/Y50-70-BIOS-Can-t
  -Save-Settings-or-boot-with-USB/m-p/3849142
