Accessing Computer Information
Before you access the updates for your computer, collect the
following information:
■ The product category is Notebook.
■ The product family name and series number are printed on
the display bezel.
■ Model information is provided on the serial number label
on the bottom of the computer.
To determine whether available ROM updates contain later ROM
versions than those currently installed on the computer, you need
to know the version of the system ROM currently installed.
ROM version information (also known as ROM date and System
BIOS) can be displayed by pressing
fn+esc (if you are already in
Microsoft Windows) or by opening Computer Setup.
To use Computer Setup for displaying ROM information:
1. Open Computer Setup by turning on or restarting the
computer, and then pressing
f10 while the “F10 = ROM
Based Setup” message is displayed in the lower-left corner
of the screen.
2. Use the arrow keys to select File > System Information,
and then press
enter.
ROM date information is displayed.
3. To exit Computer Setup, use the arrow keys to select File >
Ignore changes and exit. Then follow the instructions on
the screen.
