Called Dell ExpressSign-in, the laptop will be the first to feature a proximity sensor that can automatically detect when a user is nearby and enable Windows Hello for a hands-free log-in experience.

Making security safer shouldn't have to come at the expense of convenience. The upcoming Dell Latitude 7400 2-in-1 will include a new proximity sensor that the manufacturer says can detect motion up to three to five feet away. Once a user is detected, the laptop would automatically wake and immediately begin facial recognition for a fast hands-free log in. Of course, the feature can work in reverse and remain logged out if the laptop is unable to recognize the nearby user.

Beyond the new ExpressSign-in feature, the Latitude 7400 2-in-1 convertible is aiming to be the "world's smallest" commercial 2-in-1 for its size class at just under 15 mm thick. Its super low-power display panel and large 78 Wh battery promise a MobileMark 14 runtime of 24 hours and a charge time of just one hour from 0 to 80 percent. It's definitely something we'll have to check once we get our hands on a test unit.

See the table below for a comparison between the new Latitude 7400 2-in-1 and last year's Latitude 7490 laptop. The Latitude 7400 2-in-1 launches in March for a starting price of $1599 USD.
