Updating the BIOS
When you install a new program, hardware device, or device driver, you might be informed to update
the BIOS. You can update the BIOS from your operating system or a flash update disc (available only
on some models).
To update the BIOS, do the following:
1. Go to http://www.lenovo.com/support.
2. To update the BIOS from your operating system, download the flash BIOS update driver according to
your operating system version. To update the BIOS from a flash update disc, download the ISO image
version (used to create a flash update disc). Then, download the installation instructions for the flash
BIOS update driver.
3. Print the installation instructions you download and follow the instructions to update the BIOS.
Note: If you want to update the BIOS from a flash update disc, the installation instructions might not provide
the information about how to record the update disc. See “Recording a disc” on page 48.
Recovering from a BIOS update failure
To recover from a BIOS update failure, do the following:
1. Remove any media from the drives and turn off all connected devices and the computer. Then,
disconnect all power cords from electrical outlets and disconnect all cables that are connected to the
computer.
2. Remove the computer cover. See Chapter 9 “Installing or replacing hardware” on page 101.
3. Locate the Clear CMOS /Recovery jumper on the system board. See “Hardware locations” on page 27.
4. Remove any parts and cables that impede your access to the Clear CMOS /Recovery jumper.
5. Move the jumper from the standard position (pin 1 and pin 2) to the maintenance position (pin 2 and
pin 3).
6. Reinstall the parts and cables that were removed.
7. Reinstall the computer cover and reconnect any cables that were disconnected. See Chapter 9
“Installing or replacing hardware” on page 101.
8. Turn on the computer and insert the BIOS update disc into the optical drive. Wait a few minutes. The
recovery process begins. After the recovery process is completed, your computer will shut down
automatically.
Note: If the computer does not start up from the disc, select the disc as the startup device. See
“Selecting a temporary startup device” on page 70.
9. Repeat steps 1–4.
