Relative humidity

• Operating: 8% to 95% at wet-bulb temperature 23°C (73°F)

• Storage: 5% to 95% at wet-bulb temperature 27°C (81°F)

CAUTION:

When the computer is operating, it should be placed on a hard and flat surface with its bottom area not in contact with 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 BIOS/UEFI setup utility

• Open the boot device selection menu

• Open the Windows startup options screen

To open the Novo Button menu on your LENOVO V15 G4 AMN:

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 laptop).

Note: Alternatively, turn off the computer. Press Fn and the hotkey with a U-turn arrow icon to open the Novo Button menu.

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, activated by pressing Fn + Esc, changes how you use these hotkeys.

Note: The Esc key is in the upper left corner of the keyboard. It has an LED that indicates the status of the FnLock switch.

Your LENOVO V15 G4 AMN includes a dedicated numeric keypad on the far right of the keyboard. The keypad is used for entering numbers and operators quickly.

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

You can switch the battery’s active charging mode in Lenovo Vantage, Lenovo PC Manager, or Lenovo Smart Engine. The recommended temperature range for charging is between 10°C (50°F) and 35°C (95°F).

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 switching to conservation mode. In 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%.

By default, pressing the power button puts the computer to sleep. You can change this behavior in the Windows Control Panel.

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.

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 (UEFI/BIOS)

Customer Replaceable Units (CRUs) are parts that can be upgraded or replaced by the customer. There are two types:

• Self-service CRU: Parts that can be installed or replaced easily by customers themselves or by trained service technicians at an additional cost.

• Optional-service CRU: Parts that can be installed or replaced by customers with a greater skill level. Trained service technicians can also provide service to install or replace the parts.

The self-service CRUs defined for your LENOVO V15 G4 AMN model are:

• Power cord

• ac power adapter
