The Windows 8 model had been scheduled to launch later this month, only for Lenovo to confirm via its Facebook page that the device is now more likely to debut in the spring.
“Unfortunately we received word that it will be delayed till March or April. More details will be announced soon,” said a company spokesperson, in response to a question on the tablet's availability.
FCC filings for the ThinkPad Helix were discovered at the end of last year, and the model subsequently turned up at International CES in Las Vegas, where Lenovo officials promoted the Helix as a “high performance Ultrabook with a detachable Windows 8 tablet”.
The ThinkPad Helix has an 11.6-inch Full HD (1920 x 1080) “rip and flip” display which can used with the included QWERTY keyboard or detached for tablet-only use.
Customers can choose from a collection of Intel Ivy Bridge processors, fit their model with up to 256GB of SSD storage or 8GB of DDR3 memory, and equip the tablet with up to Windows 8 Pro. Other optional extras include LTE connectivity and a digital stylus, while the battery life of the device is estimated to be around ten hours.
Lenovo has previously said that the model will start from $1,499 when it does come to market.
