Desktop Management Interface The system BIOS (UEFI BIOS) of your computer supports an interface called System Management BIOS Reference Specification(SMBIOS) V2.6.1. SMBIOS provides information about the hardware components of your system. It is the responsibility of the BIOS to supply this database with information about itself and the devices on the system board. This specification documents the standards for getting access to this BIOS information. Preboot eXecution Environment Preboot eXecution Environment (PXE) technology makes your computer more manageable (it is PXE 2.1-compliant) by enabling it to boot (load an operating system or another executable image) from a server. Your computer supports the PC functions that PXE requires. For example, with the appropriate LAN card, your computer can be booted from the PXE server. Note: Remote Program Load (RPL)cannot be used with your computer. Wake on LAN A network administrator can use Wake on LAN to turn on a computer from a management console. When Wake on LAN is used with network management software, many functions, such as data transfer, software updates, and Flash updates of UEFI BIOS, can be performed remotely without remote attendance. This updating can be done after normal working hours and on weekends, to save time and increase productivity. Users are not interrupted during normal working hours, and LAN traffic is kept to a minimum. If a computer is turned on by the Wake on LAN function, the Network boot sequence is used. Asset ID EEPROM The Asset ID EEPROM contains information about the system, including its configuration and the serial numbers of key components. It also includes a number of blank fields in which you can record information about the end users in your network. Setting management features To enable the network administrator to control your computer remotely, you must configure the network interface by setting the system-management features in the ThinkPad Setup program. You can configure the following: • Wake on LAN • Network boot sequence • Flash update If an administrator's password (supervisor password) has been set, you will need to specify it when you start the ThinkPad Setup, so that you can use these functions. Wake on LAN When the Wake on LAN feature is enabled on a computer that is connected to a LAN, a network administrator can start the computer remotely from a management console, using remote network-management software. Setting up in the ThinkPad Setup To enable or disable Wake on LAN, go to the ThinkPad Setup menu. When your computer is not under the network administrator's system management, you can disable Wake on LAN. To set this function, do the following: 1. Start the ThinkPad Setup menu. Chapter 8.

Desktop Management Interface
The system BIOS (UEFI BIOS) of your computer supports an interface called System Management BIOS
Reference Specification(SMBIOS) V2.6.1. SMBIOS provides information about the hardware components
of your system. It is the responsibility of the BIOS to supply this database with information about itself
and the devices on the system board. This specification documents the standards for getting access to
this BIOS information.
Preboot eXecution Environment
Preboot eXecution Environment (PXE) technology makes your computer more manageable (it is PXE
2.1-compliant) by enabling it to boot (load an operating system or another executable image) from a server.
Your computer supports the PC functions that PXE requires. For example, with the appropriate LAN card,
your computer can be booted from the PXE server.
Note:
Remote Program Load (RPL)cannot be used with your computer.
Wake on LAN
A network administrator can use Wake on LAN to turn on a computer from a management console.
When Wake on LAN is used with network management software, many functions, such as data transfer,
software updates, and Flash updates of UEFI BIOS, can be performed remotely without remote attendance.
This updating can be done after normal working hours and on weekends, to save time and increase
productivity. Users are not interrupted during normal working hours, and LAN traffic is kept to a minimum.
If a computer is turned on by the Wake on LAN function, the Network boot sequence is used.
Asset ID EEPROM
The Asset ID EEPROM contains information about the system, including its configuration and the serial
numbers of key components. It also includes a number of blank fields in which you can record information
about the end users in your network.
Setting management features
To enable the network administrator to control your computer remotely, you must configure the network
interface by setting the system-management features in the ThinkPad Setup program. You can configure
the following:
Wake on LAN
Network boot sequence
Flash update
If an administrator's password (supervisor password) has been set, you will need to specify it when you start
the ThinkPad Setup, so that you can use these functions.
Wake on LAN
When the Wake on LAN feature is enabled on a computer that is connected to a LAN, a network administrator
can start the computer remotely from a management console, using remote network-management software.
Setting up in the ThinkPad Setup
To enable or disable Wake on LAN, go to the ThinkPad Setup menu. When your computer is not under the
network administrator's system management, you can disable Wake on LAN.
To set this function, do the following:
