Time-of-flight sensor

The time-of-flight sensor (also referred to as a ToF sensor) emits an infrared laser and uses the reflected infrared energy to measure the distance and depth of objects in front of it. The data collected by the sensor can be used to detect human presence or recognize gestures.

Note: The infrared laser emitted by the ToF sensor is invisible to the human eye.

CAUTION: This device contains a laser that could be damaged during repair or disassembly, which could result in hazardous exposure to infrared laser emissions. There are no user-serviceable parts within the device. Do not attempt to disassemble or service the device.

Infrared LED

The infrared LED generates and emits near-infrared waves that are received and used by a camera (or a dedicated infrared camera) for facial recognition.

Infrared camera

The infrared camera receives near-infrared waves emitted by an infrared LED and reflected by a human face. It is used for facial recognition.

Help and support

Frequently asked questions

Why does my screen brightness change constantly

Your computer may include an ambient light sensor and the adaptive brightness feature is enabled. The light sensor can detect the intensity of the surrounding light. Using data provided by the sensor, the operating system can dynamically adjust the screen brightness. The adaptive brightness feature of the operating system can be disabled. For Windows operating systems, adaptive brightness settings are usually found in Settings ➙ System ➙ Display.

Why does my computer start automatically when I open the lid

Your computer may have Flip to Start enabled. Many Lenovo notebook computers include a sensor that can detect the angle at which the lid is opened. When you open the lid, the sensor can detect this behavior. If Flip to Start is enabled, the computer will respond by starting up automatically. If you don’t like this feature, you can disable it. Flip to Start can be enabled and disabled in:

• Lenovo Vantage, Lenovo PC Manager or Lenovo Smart Engine
• Firmware Setup Utility

I enabled some dual-screen settings in the User Center app but they do not seem to work. What are the possible causes?

There are three possible causes that may prevent you from using some dual-screen functions.

• The two displays are not set in extension mode.
• The account you used to sign into Windows is not the “administrator” type.
• The account you used to sign into Windows is the “administrator” type, but another “administrator” account has not signed out of Windows yet.

What is the battery’s ship mode

When your PC’s rechargeable battery is set in ship mode, it is disconnected and does not supply power to the PC.
A battery’s ship mode is designed to prevent the battery from over-discharging, a phenomenon that is known to significantly reduce the battery capacity. Over-discharge happens when a lithium battery is at a low charge level for an extended period. In the real world, it may take a considerable amount of time for the PC to be delivered from the manufacturer to your reseller and then from the reseller to you. The PC’s rechargeable battery is set to ship mode at the factory to prevent over-discharge during this process. Before turning on your PC for the first time, plug your PC into an electrical outlet, and the battery’s ship mode is instantly disabled.
