Determining the Bios version

To determine whether available BIOS updates contain later BIOS versions than those 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 Windows) or by using Setup Utility.

1.Start Setup Utility (BIOS).

2.Use the arrow keys to select Main.

3.To exit Setup Utility (BIOS) without saving your changes, use the tab key and the arrow keys to select Exit > Exit Discarding Changes, and then press enter.

Downloading a BIOS update

CAUTION: To reduce the risk of damage to the computer or an unsuccessful installation, download and install a BIOS update only when the computer is connected to reliable external power using the AC adapter. Do not download or install a BIOS update while the computer is running on battery power, docked in an optional docking device, or connected to an optional power source. During the download and installation, follow these instructions:

Do not disconnect power from the computer by unplugging the power cord from the AC outlet.

Do not shut down the computer or initiate Sleep or Hibernation.

Do not insert, remove, connect, or disconnect any device, cable, or cord.

Windows XP—Select Start > Help and Support, and then select the software and drivers update.

2.Follow the on-screen instructions to identify your computer and access the BIOS update you want to download.

3.At the download area, follow these steps:
