Fingerprint reader

The fingerprint reader is an option on this model series.

If your system does not have a fingerprint sensor, one can be purchased and installed.

It might be necessary to also replace the top cover.

Webcam / Camera

Windows Hello facial recognition requires an IR type camera.

The service manual for your computer indicates that, if a camera option is included (that is, if your computer has a webcam), the installed webcam / camera is NOT the type to support Windows Hello facial recognition.

WWAN / Mobile Broadband adapter / module

SIM card / Mobile Network Service Carrier

Prerequisite - "Must have"

Computer or Workstation must include the hardware options to install both SIM card and the WWAN module.

Connecting your computer to your mobile network service provider requires two main parts:

• A supported, account active SIM card to connect to your provider's network
• An appropriate and installed WWAN broadband module inside the computer

Many computers come with a built-in slot for a SIM card.

Many more computers do NOT come with the optional WWAN broadband module already installed.

Your computer includes the OPTION to purchase and install the WWAN Mobile Broadband module.
