Human being presence detection (HPD) is a feature that is condign ever more prevalent in modernistic laptops. It might be called something different depending on the manufacturer — HP calls it "Presence Aware," for instance — but the stop event remains the aforementioned. Your laptop tin sense when you're sitting or continuing in front of it, and it can sense when you lot walk away.

Dell'south Breadth 7400 ii-in-one was the world's first commercial laptop to utilize this feature. Dell calls the platform ExpressSign-In, which is based on Intel's Context Sensing Technology. Together with an IR camera and Windows Hello, ExpressSign-In (or any other HPD culling) provides users with immediate and touch-complimentary Windows x logins when the laptop is in Standby mode. But walk up to or sit downwardly at your laptop, and you lot'll be signed in apace and securely.

In most cases, HPD doesn't stop working while you're at your PC. Every bit long as it senses your presence nearby, it will continue the laptop awake. If you walk abroad from your laptop, it will lock your device after a set corporeality of time. Perhaps most importantly, an HPD sensor tin can just tell that there'southward someone in that location, but it can't tell who it is. That part is left up to a Windows Hello IR photographic camera.

While Dell introduced HPD to many of us with its ExpressSign-In technology on the Latitude line, other major manufacturers haven't been far backside. The HP EliteBook x360 1040 G7 is notably equipped with Presence Aware. It has a time-of-flight (ToF) sensor that notes your presence without requiring a camera to be on all the time, something nearly security-minded folks can appreciate. The VAIO Z also has a ToF sensor for HPD.

Some of Lenovo's latest Ten-series ThinkPads, including the X1 Yoga, X1 Carbon, and X1 Nano, are employing a NOVELDA human presence sensor. No matter what it's called, it all achieves the same end goal.

Presence detection is tied heavily to Intel'due south 11th Gen Core processor (CPU) series, and we expect to see plenty more of the all-time Windows laptops in the virtually time to come shipping with the feature.

Human presence detection isn't required for Windows Hello or for the normal operation of your laptop. It's simply another feature that makes using a Windows laptop that much more intuitive.

Along with the convenience of having your laptop ready to go before touching anything, HPD boosts security by locking your laptop when you move away from it. This isn't a huge bargain if you piece of work from dwelling house, but if yous work in an office or some public setting, having your PC lock automatically can salve you from a potential security headache.

In virtually cases, those who don't need the actress feature or those who aren't comfortable with the sensor can remove a laptop's HPD ability through accompanying software.
