Chinese PC maker Lenovo, keen to grow its mobile device portfolio, seemed also set on entering the fitness wearable space with a market-differentiating quirky twist – it can unlock your PC – but a product description on the firm’s website has now been pulled, suggesting the ‘unveiling’ was premature.

In a filing with US telecoms regulator FCC earlier this month, Lenovo confirmed it was working on a wearable device – Smartband SW-B100 – but details were sparse.

The product description, spotted by a few websites, filled in some of the gaps.

Apparently, the Lenovo Smartband is “for young people who take care of their personal health and are interested in new tech trend products”.

PCWorld said, however, it was unclear how the unlocking feature would work, concluding it would probably require extra software on the Windows side (Lenovo said the PC must be running Windows 8 or higher).

Other features include a small display that can show the time, incoming calls, and SMS alerts (and can remind you to exercise).

Smartband can also count steps, estimate calories burned, measure heart rate and monitor sleep, and compile all the data in a companion app for iOS and Android.

There was no price or release date in the hastily-removed description.
