Software updates Accessing computer information Before you access the updates for your computer, collect the following information: ■ The product category is Notebook. ■ The product family name, series number, and serial number (S/N) are provided on the service tag. To determine whether an available BIOS update contains a later BIOS version than the one currently installed on the computer, you need to know the version of the system BIOS currently installed. BIOS 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 BIOS information: 1.

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. Software Update, Backup and Recovery 1-3
