The new one-bar hinge, dual fan, and rear venting for an improved Intelligent Thermal Solution mean you can put in long hours on the job, and the ThinkPad X1 Carbon Gen 9 laptop will stay as cool as you are. Biometrics provide an extra-secure fingerprint reader that is standard and is integrated with the power button-so you can log in and boot up instantaneously. Human-presence detection automatically locks your device when you move away, and in combination with the optional IR camera, it enables zero-touch login even from sleep. Plus, choose the PrivacyGuard display panel to ensure wandering eyes can't see what's on your screen.
