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 (BIOS).
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.
1. Select Start > Help and Support > Maintain.
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:
a. Identify the BIOS update that is later than the BIOS version currently installed on your
computer. Make a note of the date, name, or other identifier. You may need this information
to locate the update later, after it has been downloaded to your hard drive.
b. Follow the on-screen instructions to download your selection to the hard drive.
Make a note of the path to the location on your hard drive where the BIOS update is
downloaded. You will need to access this path when you are ready to install the update.
NOTE: If you connect your computer to a network, consult the network administrator before
installing any software updates, especially system BIOS updates.
BIOS installation procedures vary. Follow any instructions that are displayed on the screen after the
download is complete. If no instructions are displayed, follow these steps:
1. Open Windows Explorer by selecting Start > Computer.
2. Double-click your hard drive designation. The hard drive designation is typically Local Disk (C:).
3. Using the hard drive path you recorded earlier, open the folder on your hard drive that contains
the update.
4. Double-click the file that has an .exe extension (for example, filename.exe).
The BIOS installation begins.
5. Complete the installation by following the on-screen instructions.
