NOTES

- Be aware that the OS Optimized Defaults option in the Restart menu of ThinkPad
  Setup should not be normally changed. Lenovo recommends to use the factory
  default setting for it, as follows.


  - OS Optimized Defaults                              [Enabled]

  If the OS Optimized Defaults setting is changed, Setup Default by the F9 key
  will not load the same default configuration, as follows. Furthermore, by the
  condition of Operating System installation, the computer may not be booted due
  to the setting change.

  If your computer runs satisfactorily now, you have no need to change the OS
  Optimized Defaults option. If you need to change the setting, consider well
  the effect of the setting change.

  Affected Setup menu items :
  "OS Optimized Defaults" setting          [Disabled] case      [Enabled] case
  - Security
    - UEFI BIOS Update Option
      - Secure RollBack Prevention         [Disabled]           [Enabled]
