Tips
• Turn off the computer before cleaning the multi-touch screen.
• Use a dry, soft, and lint-free cloth or a piece of absorbent cotton to remove fingerprints or dust from the
multi-touch screen. Do not apply solvents to the cloth.
• The multi-touch screen is a glass panel covered with a plastic film. Do not apply pressure or place any
metallic object on the screen, which might damage the touch panel or cause it to malfunction.
• Do not use fingernails, gloved fingers, or inanimate objects for input on the screen.
• Regularly calibrate the accuracy of the finger input to avoid a discrepancy.
Using the Privacy Guard feature (for selected models of T490)
Depending on the model, your computer might support the Privacy Guard feature.
The Privacy Guard feature prevents others from peeking at your screen to protect your privacy whenever
needed. When the feature is enabled, it darkens the screen and narrows the viewing angle, making the
screen content easily visible only to the people in front of the computer.
By default, the Privacy Guard feature is disabled. To enable or disable this feature, do one of the following:
• Press Fn+D.
• Press F12 (when the Fn Lock indicator is off) or Fn+F12 (when the Fn Lock indicator is on).
• Open the Start menu and then click Lenovo Vantage ➙ Hardware Settings ➙ Audio/Visual. Locate the
Privacy Guard section to turn on or turn off the switch.
Note: You will be prompted by the on-screen display every time the feature is enabled or disabled.
Automatic Privacy Guard feature for passwords
Note: The automatic Privacy Guard feature for passwords is not supported on computers with the Ubuntu
operating system.
The Privacy Guard feature is turned on automatically when you are required to input the password for a
password-protected object, such as an encrypted document or a Web site that needs password
authentication. To select this feature:
1. Open the Start menu and then click Lenovo Vantage ➙ Hardware Settings ➙ Audio/Visual.
