Review: Lenovo Helix Ultrabook Convertible


Ports And Comms

Like most Ultrabooks, Helix is a tad stingy with ports, but the keyboard dock helps make up for it. As a tablet, Lenovo provides a SIM slot, 3.5mm headset jack, one USB 2.0 port and a Dual Mode DisplayPort (D++) with Mini DisplayPort connector. D++ automatically detects the type of external monitor that's connected and adjusts accordingly to support 4K resolutions and stereoscopic 3-D. The tablet also has buttons for power, volume and screen rotation control. The dock delivers two USB 3.0 ports and passes the D++ port along. All connections are in the rear. There's also Wi-Fi a/b/g/n, NFC, Bluetooth 4.0 and wired Ethernet thanks to an included USB dongle that works in tablet or laptop mode. One of our nits is the upper-right location of the headset jack, which causes a speaker or headphone wire to dangle high in space. Another is the absence of an SD slot. For security, a sliding metal tab allows the tablet to be locked within the dock and the dock to be secured to an immovable object using an optional lock and/or cable.
