Updating your system UEFI BIOS

The Unified 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 flash memory). You can update UEFI BIOS and the Configuration/ThinkPad Setup program by starting your computer with a flash update optical disc or flash 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.

To update your UEFI BIOS, go to the following Web site and follow the instructions on the screen: http://www.lenovo.com/ThinkPadDrivers
