Creating and using recovery media
You can use recovery media to restore the hard disk drive to the factory default settings. Recovery media
are useful if you transfer the computer to another area, sell the computer, recycle the computer, or put the
computer in an operational state after all other methods of recovery have failed. As a precautionary measure,
it is important to create recovery media as early as possible.
Note: The recovery operations you can perform using recovery media vary depending on the operating
system from which the recovery media were created. The recovery media might contain a boot medium
and a data medium. Your Microsoft Windows license permits you to create only one data medium, so it is
important that you store the recovery media in a safe place after you have made them.
Creating recovery media
This section provides instructions on how to create recovery media on different operating systems.
Note: On the Windows 7 operating system, you can create recovery media using discs or external USB

Chapter 5. Updating system programs
This chapter provides information about updating the POST and BIOS, and how to recover from a POST
and BIOS update failure.
This chapter contains the following topics:
•
•
•
•
Using system programs
System programs are the basic layer of software built into your computer. System programs include the
POST, the BIOS, and the Setup Utility program. The POST is a set of tests and procedures that are
performed each time you turn on your computer. The BIOS is a layer of software that translates instructions
from other layers of software into electrical signals that the computer hardware can execute. You can use
the Setup Utility program to view or change the configuration settings of your computer. See Chapter 4
Your computer system board has a module called electrically erasable programmable read-only memory
(EEPROM, also referred to as flash memory). You can easily update the POST, the BIOS, and the Setup
Utility program by starting your computer with a system-program-update disc or running a special update
program from your operating system.
Lenovo might make changes and enhancements to the POST and BIOS. When updates are released, they
are available as downloadable files on the Lenovo Web site at http://www.lenovo.com. Instructions for using
the POST and BIOS updates are available in a TXT file that is included with the update files. For most
models, you can download either an update program to create a system-program-update disc or an update
program that can be run from the operating system.
Updating (flashing) the BIOS from a disc
This section provides instructions on how to update (flash) the BIOS from a disc.
Note: You can download a self-starting bootable disc image (known as an ISO image) with the system
program updates to create a system-program-update disc. Go to:
To update (flash) the BIOS from a disc, do the following:
1. Turn off your computer.
2. Repeatedly press and release the F12 key when turning on the computer. When the Startup Device
Menu opens, release the F12 key.
3. On the Startup Device Menu, select the desired optical drive as the first boot device. Then, insert the
disc into the optical drive and press Enter. The update begins.
4. When prompted to change the serial number, it is suggested that you press N. However, if you do want
to change the serial number, press Y, then type in the serial number and press Enter.

to change without notice, including the contents referenced in the following procedure.
To update (flash) the BIOS from your operating system, do the following:
2. Do the following to locate the downloadable files for your machine type:

c. Select BIOS from the Refine results drop-down list box to easily locate all the BIOS related links.
d. Click the BIOS update link.
3. Click the TXT file that contains the instructions for updating (flashing) the BIOS from your operating
system.
4. Print these instructions. This is very important because these instructions will not be displayed on
the screen after the download begins.
5. Follow the printed instructions to download, extract, and install the update.
Recovering from a POST/BIOS update failure
If the power to your computer is interrupted while the POST/BIOS is being updated (flash update), your
computer might not restart correctly. If this happens, perform the following procedure commonly called
Boot-block Recovery.
1. Remove all media from the drives and turn off all attached devices and the computer. Then, disconnect
all power cords from electrical outlets and disconnect all cables that are connected to the computer.
4. Move the jumper from the standard position (pin 1 and pin 2) to the maintenance position (pin 2 and
pin 3).
5. Install the computer cover and reconnect all cables and power cords that were disconnected. See
6. Repeatedly press and release the F12 key when turning on the computer. When the Startup Device
Menu opens, release the F12 key.
7. Insert the POST/BIOS update (flash) disc into the optical drive. Then, select the optical drive as the
startup device and press Enter. The recovery session begins.
Note: The recovery session will take two to three minutes. During this time you will hear a series
of beeps.
8. After the recovery session is completed, the series of beeps will end, and the system will automatically
turn off. Remove the disc from the optical drive before the system completely turns off.
9. Repeat steps 1 through 3.
10. Move the Clear CMOS /Recovery jumper back to the standard position (pin 1 and pin 2).
