Use the PrivacyGuard feature
When the feature
is enabled, it darkens screen and reduces visibility from side angles
to protect screen content against visual hacking. By default, the
PrivacyGuard feature is disabled. You can press Fn+D to enable it.
You will be prompted by the on-screen icon
or
every time the feature
is enabled or disabled.
The privacy level of this feature varies
depending on the screen brightness level, the contrast ratio, and
the physical environment where you are using this feature.
Automatic PrivacyGuard feature for passwords
Though the PrivacyGuard feature is disabled, PrivacyGuard feature
could also be automatically enabled in case that you are required
to input passwords. By default, this automatic PrivacyGuard feature
for passwords is disabled. You can enable it on Lenovo Vantage.
Note: The automatic PrivacyGuard feature for passwords is not supported
on computers with the Linux® operating system.
Use the PrivacyGuard with PrivacyAlert feature
Glance by Mirametrix® is preinstalled on your
computer. Turn on PrivacyAlert and PrivacyGuard switches on Glance to achieve better
privacy protection.
When someone is detected looking over your
shoulder by the camera (with IR function), an alert icon appears on
your computer screen. Meanwhile, PrivacyAlert automatically enables
PrivacyGuard to prevent peeking eyes. When the person leaves, the
icon disappears and the PrivacyGuard feature is disabled automatically.
