Updating your system UEFI BIOS
The Unied Extensible Firmware Interface (UEFI) BIOS is a part of the system programs that make up the
basic layer of software built into your computer. 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 UEFI BIOS and the Conguration/ThinkPad
Setup program by starting your computer with a ash update optical disc or ash update tool application
running on the Windows environment.
In some instances when you add software, hardware, or a device driver, you may be informed that you need
to update your UEFI BIOS in order for the new addition to work properly.
