CAUTION:

When the computer is operating, it should be placed on a hard and flat surface with its bottom area not in contact with the user’s bare skin. Under normal operating conditions, the temperature of the bottom surface will remain within an acceptable range as defined in IEC 62368-1, but such temperatures can still be high enough to cause discomfort or harm to the user if directly touched for over one minute at a time. As such, it is recommended that users avoid prolonged direct contact with the bottom of the computer.

To configure settings, type the corresponding keywords in the Windows search box and select the best match. Follow the on-screen instructions to customize settings.

The Novo Button menu can be displayed before the operating system starts. From the menu, you can choose to:

Open the Windows startup options screen

To open the Novo Button menu:

Step 1. Turn off the computer.

Step 2. Open the LCD screen and press the Novo button (located in a small hole on the side of the computer).

Hotkeys are keys on the top row of your keyboard with printed icons that provide shortcuts to frequently used functions. They share keys with function keys (F1-F12).

The FnLock switch

The FnLock is an electronic switch that affects how you use hotkey functions. To turn it on and off, press Fn + Esc. The Esc key has an LED that indicates the status of the FnLock switch.

Note: The FnLock switch does not apply to hotkeys not found in the first row of the keyboard. To use these hotkeys, always hold down the Fn key while pressing the key.

Your LENOVO V15 G4 IRU 2 includes a dedicated numeric keypad on the far right of the keyboard for entering numbers and operators quickly.

Press the NumLock key to enable or disable the numeric keypad.

Your computer may be pre-installed with Lenovo Vantage, Lenovo PC Manager, or Lenovo Smart Engine to manage these features.

Eye Care Mode

Eye Care Mode intelligently adjusts the color temperature of the screen and can reduce the chances of developing eye fatigue or eye strain.

Smart Noise Cancelling

By filtering the input and output environments, Smart Noise Cancelling helps you reduce noise and optimize the call effect in different scenarios.

You can switch the battery’s active charging mode in Lenovo Vantage, Lenovo PC Manager, or Lenovo Smart Engine. The battery packs support multiple charging modes for different usage habits.

Normal mode

This is the most basic charging mode. It typically takes 2 to 4 hours for the battery to charge from 0% to 100%.

Rapid charge mode

If you want the battery to be charged faster than in normal mode, switch to rapid charge mode. It typically takes less than 1 hour to charge from 0% to 80% and less than 2 hours to charge from 0% to 100%.

Conservation mode

If your computer is constantly plugged into an electrical outlet, consider this mode. The battery’s charge will be kept within 75%–80%, which is beneficial to the long-term health of the battery.

If your computer is constantly plugged in and the battery rarely discharges, it may not charge to its full capacity even if the battery meter reports 100%. You can recover the battery’s full charging potential by discharging and re-charging it.

Step 1. Unplug the computer and use it until the battery charge drops below 20%.

Step 2. Plug in the computer and charge the battery to 100%.

Press and hold the power button until the computer turns off. Then restart the computer.

1. Carefully unplug the ac power adapter and turn off the computer immediately. The more quickly you stop the current from passing through the computer the more likely you will reduce damage from short circuits.

Attention: Although you might lose some data or work by turning off the computer immediately, leaving the computer on might make your computer unusable.

2. Wait until you are certain that all the liquid is dry before turning on your computer.

CAUTION: Do not try to drain out the liquid by turning over the computer. If your computer has keyboard drainage holes on the bottom, the liquid will be drained out through the holes.

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.

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. If Flip to Start is enabled, the computer will respond by starting up automatically when you open the lid.
