1 Security-lock slot
To protect your computer from theft, purchase a security cable lock, usually a Kensington-style cable lock,
that fits this security-lock slot to lock your computer to a stationary object.
2 ac power connector
3 Lenovo OneLink connector
When the ac power adapter is connected to the ac power connector, it provides ac power to the computer
and charges the battery. When a supported ThinkPad OneLink Dock is connected to the Lenovo OneLink
connector, it can not only extend the computer capabilities but also provide ac power to the computer
and charge the battery.
To use the Lenovo OneLink connector, you need to remove the connector cover from the Lenovo OneLink
connector first.
Note: Ensure that you keep the connector cover. Reattach it to the Lenovo OneLink connector when
you are not using the Lenovo OneLink connector.
4 Always On USB connector
By default, the Always On USB connector enables you to charge some mobile digital devices and
smartphones when your computer is in sleep or hibernation mode.
If you want to charge these devices when your computer is turned off, do the following:
1. Connect the computer to an ac power supply.
2. Go to ThinkPad Setup and enable Always On USB Charge in off mode. For more information, see
"Config menu" on page 71.
