Depending on many factors such as the processing capability of the host and peripheral devices, file attributes, and other factors related to system configuration and operating environments, the actual transfer rate using the various USB connectors on this device will vary and will be slower than the data rate listed below for each corresponding device.

Maximum altitude (without pressurization)

3048 m (10 000 ft)

Temperature

• At altitudes up to 2438 m (8000 ft)

– Operating: 5°C to 35°C (41°F to 95°F)

– Storage: 5°C to 43°C (41°F to 109°F)

• At altitudes above 2438 m (8000 ft)

– Maximum temperature when operating under the unpressurized condition: 31.3°C (88°F)

When you charge the battery, its temperature must be no lower than 10°C (50°F).

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)

Yes. 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 BIOS/UEFI setup utility, the boot device selection menu, or the Windows startup options screen.

To open the 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).

Alternatively, you can turn off the computer, then press Fn and the designated hotkey to open the Novo Button menu.

Hotkeys are on the top row of the keyboard and provide shortcuts to frequently used functions. They share keys with function keys (F1-F12). The FnLock switch, toggled by pressing Fn + Esc, changes how these keys work.

The Esc key has an LED to indicate the status of the FnLock switch.

Your LENOVO V14 G4 IRU 3 includes a dedicated numeric keypad on the far right of the keyboard. This keypad is used for entering numbers and operators quickly. Press the NumLock key to enable or disable the numeric keypad.

Your computer may have the following features, which can be managed through apps like Lenovo Vantage:

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, this feature 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 available modes are:

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.

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 be charged to its full capacity even if the battery meter reports 100% charge. To recover the battery’s full charging potential, simply discharge and re-charge 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.

Step 1. Type Control Panel in the Windows search box and then press Enter. Open the control panel and view by large or small icons.

Step 2. Select the power options and then click choose what the power button does.

You can switch the operation mode in a pre-installed Lenovo app or by using the key combination Fn + Q. The modes vary performance, power consumption, and fan speed.

UEFI/BIOS is the first program that runs when a computer starts. It initializes hardware components and loads the operating system. You can change certain UEFI/BIOS settings in its setup utility.

Step 1. Turn on or restart the computer.

Step 2. Before the Lenovo logo appears on the screen, press F2 repeatedly.

For computers with hotkey mode enabled, press Fn + F2.

If you need to start the computer from a device other than its main storage drive (e.g., a USB drive), you can use the boot menu.

Step 1. Turn on or restart the computer.

Step 2. Press F12.

Step 3. From the boot device menu, select a boot device to start the computer.

To make a permanent change, enter the UEFI/BIOS setup utility, select the Boot menu, choose the desired boot device in the EFI section, and move it to the top of the list. Save changes and exit.

The administrator password prevents unauthorized access to the UEFI/BIOS setup utility.

Set administrator password:

Step 1. Open the UEFI/BIOS setup utility.

Step 2. Select Security → Set Administrator Password and press Enter.

Step 3. Enter a password string (letters and numbers only) and press Enter.

Step 4. Enter the password again and press Enter.

Step 5. Select Exit → Exit Saving Changes.

If the administrator password has been set, you can enable a power-on password for greater security. You must enter the administrator or user password to start the computer.

Step 1. Open the UEFI/BIOS setup utility.

Step 2. Select Security → Power on Password and press Enter.

Step 3. Change the setting to Enabled.

Step 4. Select Exit → Exit Saving Changes.

When Flip to Start is enabled, you can turn on the computer by flipping open the screen. You can change this setting in the UEFI/BIOS setup utility.

Step 2. Select Configuration.

Step 3. Change the setting for Flip to Start.

You may also set Flip to Start in Lenovo Vantage, Lenovo PC Manager or Lenovo Smart Engine.

You can set a hard disk password to prevent unauthorized access to your data. Be extremely careful, as a forgotten hard disk password cannot be reset.

Set hard disk password:

Step 1. Open the UEFI/BIOS setup utility.

Step 2. Select Security → Set Hard Disk Password and press Enter.

Step 3. Follow on-screen instructions to set both master and user passwords. They must be set at the same time.

Step 5. Select Exit → Exit Saving Changes.

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.

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

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.

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.

• 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.

The table below lists the CRUs and CRU types that are defined for your product model.

The keyboard of your LENOVO V14 G4 IRU 3 should only support a subset of the listed hotkeys. The function is denoted by the icon on the key.
