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 BIOS setup utility.

The Lenovo G-series model supports Switchable Graphics in two modes:

Mode 1 Select the graphics processor based on application needs

In this mode, the system allocates a graphics processor to some applications
automatically. Alternatively, you can also manually select a graphics
processor for your applications.
The default setting of your computer is Mode 1. To switch to Mode 2, please
refer to “Switching between Mode 1 and Mode 2”.

Mode 2 Select the graphics processor manually or based on power
source

In this mode, you can select a graphics processor manually or based on the
power source status (AC/DC):
• High-performance GPU: It is also referred to as the independent GPU,

which can provide higher graphics processing and display performance.

• Power-Saving GPU: It is also referred to as the integrated GPU, which can

enable a longer running time of the battery.

Switch between the two graphics processors as follows:
1 Start your computer under the Windows 7 operating system.
2 Click Start → All Programs → Catalyst Control Center, and run the CCC.
3 Click Power → Switchable Graphics on the Catalyst Control Center

setting page.

Note:

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