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.

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 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 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.

Alternatively, turn off the computer. Press Fn and the hotkey to open the Novo Button menu.

Hotkeys are keys on the top row of the keyboard with printed icons that provide shortcuts to frequently used functions. They share keys with function keys (F1-F12). The FnLock is an electronic switch (Fn + Esc) that affects how you use hotkey functions.

Some models include 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.

Your computer may be pre-installed with Lenovo Vantage, Lenovo PC Manager, or Lenovo Smart Engine. These features can be enabled or disabled in one of these apps.

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 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.

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%. This 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%.
