Setting the configuration incorrectly might cause unexpected results. • On each submenu, press Enter to show selectable options and select a desired option, or type desired values from the keyboard directly. • Some items are displayed on the menu only if the computer supports the corresponding features.

Enable or disable the function that protects items in ThinkPad Setup from being changed by a user who does not have the supervisor password. By default, this is set to Disabled. If you set the supervisor password and enable this function, no one but you can change any items in ThinkPad Setup. If you select and enable Password at unattended boot, a password prompt is displayed when the computer is turned on, from either a power-off state or hibernation state, by an unattended event such as Wake on LAN. If you select Disabled, no password prompt is displayed; the computer goes ahead and loads the operating system. To prevent unauthorized access, set the user authentication on the operating system. 112 User Guide
