Lenovo Vantage

The preinstalled Lenovo Vantage is a customized one-stop solution to help you maintain your computer with automated updates and fixes, configure hardware settings, and get personalized support.

Access Lenovo Vantage

Open the Start menu and click Lenovo Vantage. You also can type Lenovo Vantage in the search box.

To download the latest version of Lenovo Vantage, go to Microsoft Store and search by the app name.

Key features

Lenovo Vantage enables you to:

• Know the device status easily and customize device settings.

• Download and install UEFI BIOS, firmware and driver updates to keep your computer up-to-date.

• Monitor your computer health, and secure your computer against outside threats.

• Scan your computer hardware and diagnose hardware problems.

• Look up warranty status (online).

• Access User Guide and helpful articles.

Notes:

• The available features vary depending on the computer model.

• Lenovo Vantage makes periodic updates of the features to keep improving your experience with your computer. The description of features might be different from that on your actual user interface.

Color sensor (for selected models)

The color sensor enables you to measure and adjust the color accuracy of your computer display. Therefore, a color image or graphic is rendered as close as possible to its original intent. The color profile for your computer display is preinstalled on your computer. If you want to install a different color profile, go to:

https://pcsupport.lenovo.com

To use the color sensor, open the Start menu, click X-Rite ➙ PANTONE Color Calibrator, and then follow the on-screen instructions.

When the color sensor is in use, the color-sensor indicator on the computer outer lid blinks twice at regular intervals. When the color measuring and adjustment finishes, the color-sensor indicator stays on.

After you use the color sensor for the first time, a calibration profile ECCM2SensorData.dat is generated. Back up this calibration profile on an external storage device in case that both the color sensor and the internal storage device are replaced.

To locate the DAT file, go to This PC ➙ Documents ➙ X-Rite.

The display provides a color profile that can work with the Microsoft Image Color Management (ICM) function. If the graphics software you are using is compatible with ICM, you can display a color image on your monitor and match it with the same quality one on another device, such as a scanner or a printer.

For more information about the Microsoft ICM, see the Windows help information.

Night light

Blue light is the high-energy visible light in the light spectrum. Excessive exposure to blue light might damage your vision. Night light is a feature that reduces the blue light emitted from computer screens. When the night light is on, your computer display shows warmer colors that help you reduce eye strain and fall asleep. For more information about low blue light and instructions , go to

Note: Selected Lenovo computers are low blue-light certified. These computers are tested with night light turned on and color temperature set to the default value of 48.

To turn on or turn off the night light:

• Type Night light in the search box. Click Night light. Then, follow the on-screen instructions.

• Open the Start menu. Click Settings ➙ System ➙ Display. Then, turn on or turn off the Night light

Ergonomic information

Good ergonomic practice is important to get the most from your personal computer and to avoid discomfort. Arrange your workplace and the equipment you use to suit your individual needs and the kind of work that you perform. In addition, use healthy work habits to maximize your performance and comfort when using your computer.

Working in the virtual office might mean adapting to frequent changes in your environment. Adapting to the surrounding light sources, active seating, and the placement of your computer hardware, can help you improve your performance and achieve greater comfort.

This example shows someone in a conventional setting. Even when not in such a setting, you can follow many of these tips. Develop good habits, and they will serve you well.

General posture: Make minor modifications in your working posture to deter the onset of discomfort caused by long periods of working in the same position. Frequent short breaks from your work also help to prevent minor discomfort associated with your working posture.

Appendix A. Accessibility and ergonomic information 39

Display: Position the display to maintain a comfortable viewing distance of 510 mm to 760 mm (20 inches to 30 inches). Avoid glare or reflections on the display from overhead lighting or outside sources of light. Keep the display screen clean and set the brightness to levels that enable you to see the screen clearly. Press the brightness control keys to adjust display brightness.

Head position: Keep your head and neck in a comfortable and neutral (vertical, or upright) position.

Chair: Use a chair that gives you good back support and seat height adjustment. Use chair adjustments to

best suit your comfort posture.

Arm and hand position: If available, use chair arm rests or an area on your working surface to provide weight support for your arms. Keep your forearms, wrists, and hands in a relaxed and neutral (horizontal) position. Type with a soft touch without pounding the keys.

Leg position: Keep your thighs parallel to the floor and your feet flat on the floor or on a footrest.
