Using the NFC connection

Near field communication is a high-frequency and short-range wireless communications technology.
Depending on the model, your computer might come with the NFC feature. By using the NFC feature, you
can establish the radio communications between your computer and another NFC-enabled device over a
distance no more than a few centimeters.
By default, the NFC feature is enabled. If the NFC feature of your computer is disabled, do the following to
enable the NFC feature:
• For Windows 7:
1. Start the ThinkPad Setup program. See "Using the ThinkPad Setup program" on page 97.
2. Select Security ➙ I/O Port Access.
3. Set the NFC device option to Enabled.
• For Windows 8 and Windows 8.1:
1. Move the pointer to the top-right or bottom-right corner of the screen to bring up the charms.
2. Do the following:
– For Windows 8: Click Settings ➙ Change PC settings ➙ Wireless.
– For Windows 8.1: Click Settings ➙ Change PC settings ➙ Network ➙ Radio devices.
3. Slide the NFC switch to the right to enable the NFC feature.
If you still cannot enable the NFC feature, check the NFC device setting in the ThinkPad Setup program
by doing the following:
1. Start the ThinkPad Setup program. See "Using the ThinkPad Setup program" on page 97.
2. Select Security ➙ I/O Port Access.
3. Set the NFC device option to Enabled.
You can use the NFC feature with NFC supported programs, such as the Lenovo QuickCast program
and the Lenovo QuickControl program.
