5 Monitor connector
You can attach an external monitor or a projector to your computer to display computer information.
Note: If you attach your computer to the ThinkPad Ultrabase Series 3 and use a monitor connector, use the
monitor connector on the ThinkPad Ultrabase Series 3, not the one on the computer.
For details, refer to the instructions in “Attaching an external monitor” on page 71.
6 USB connector
The Universal Serial Bus connectors are used for connecting devices compatible with a USB interface,
such as a printer or a digital camera.
Notes:
• Your computer may look slightly different from the illustrations.
• Your computer is compatible with USB 1.1 and 2.0. Some models are also compatible with USB 3.0.
• If your computer is a USB 3.0 model, any function specific to USB 3.0 will not work until your Windows
operating system has been started. However, USB 2.0 or 1.0 devices will work.
