According to a recent report by GSM Arena, Taiwanese device manufacturer Asus is bringing back the keyboard dock feature to its PadFone device.

A couple of years back, Asus had launched its PadFone device with a laptop dock function; but, for some reason, the company had dropped the laptop functionality. However, as per the GSM Arena report, the discontinued feature is now being brought back by Asus once again.

As per a leaked document in the FCC, Asus' PadFone device will feature an 'ASUS Mobile Dock Keyboard' which will boast the capability of connecting to the PadFone via Bluetooth.

The report implies that the current Asus PadFone devices will now be capable of three transformations --- one for the smartphone; one with the tablet dock; and, lastly, one with the keyboard dock.

However, though the Asus PadFone Mobile Dock Keyboard underscores a good addition for the Asus brand, the keyboard dock does not have an extended battery for increasing the battery life of the PadFone device. Instead, it only features a 450mAh battery pack which can power its own tasks and features, like Bluetooth connectivity and keyboard functions.

Moreover, since there is no provision of extended storage capacity in the PadFone, users will still have to get a flash drive or portable hard drive if they want to expand the storage of their PadFone.
