Chapter 2. Learning the basics

 Using passwords

Using passwords helps prevent your computer from being used by others.

Once you set a password and enable it, a prompt appears on the screen each

time you power on the computer. Enter your password at the prompt. The

computer cannot be used unless you enter the correct password.

For details about how to set the password, see the Help to the right of the

screen in the BIOS setup utility.

About NVIDIA

Optimus

(on select models)

Optimus is a GPU switching mechanism which automatically switches the

active GPU to perform image-rendering tasks. If no graphics-intensive

programs are running, the integrated GPU will be selected as the active GPU

to preserve battery life; if you start high-definition movie playback or a 3D

game, the image-rendering task is automatically switched by Optimus to the

discrete GPU to produce high graphics performance.

When Optimus is enabled, switching between integrated and discrete GPUs

is performed automatically without user intervention.

Note: This password can be from one to seven alphanumeric characters in any combination.

Note: To enter BIOS setup utility, press F2 when the Lenovo logo appears on the screen while

the computer is starting up.
