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 Windwos 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, visit this Web site at http://www.lenovo.com/ThinkPadDrivers. Then follow
the instructions on the screen.
Using system management
This section is intended primarily for network administrators.
Your computer is designed for manageability, so that you can redirect more of your resources to better
meet your business objectives.
This manageability, or "Total Cost of Ownership" (TCO), enables you to remotely power on your computer,
format the hard disk drive, install the software of your choice (for example, Windows XP with user and
system-management applications), and have the computer start up and function in the same way as an
ordinary desktop PC.
Once the computer is configured and operational, you can manage it by use of software and manageability
features already integrated into the client system and the network.
