When the ac power adapter is connected to the ac power connector, the ac power adapter provides ac
power to the computer and charges the battery. When a supported ThinkPad OneLink Dock option is
connected to the Lenovo OneLink connector, the option 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 rst.
3 Always On USB 3.0 connector
By default, the Always On USB 3.0 connector enables you to charge some mobile digital devices and
smartphones when your computer is in the following situations:
• When your computer is on or in sleep mode
• When your computer is in hibernation mode or is turned off, but connected to ac power
If you want to charge these devices when your computer is in hibernation mode or is turned off, and the
computer is not connected to ac power, do the following:
• Press the Windows key to go to the Start screen.
• Click Lenovo Settings ➙ Power. Then select Enable USB charge from the computer battery even
