Updating your system UEFI BIOS
The Unied Extensible Firmware Interface (UEFI) BIOS is a part of the system programs that make up the
basic layer of software built into your computer. The UEFI BIOS translates the instructions from other
software layers.
Your computer system board has a module called electrically erasable programmable read-only memory
(EEPROM, also referred to as ash memory). You can update the UEFI BIOS and the Conguration/ThinkPad
Setup program by starting your computer with a ash update optical disc or ash update tool application
running in the Windows environment.
In some instances when you add software, hardware, or a device driver, you might be informed that you
need to update your UEFI BIOS in order for the new addition to work properly.
To update your UEFI BIOS, go to the following Web site and follow the instructions on the screen:
