PC Pro says that the Series 5 Hybrid includes an 11.6-inch screen-toting tablet, the largest produced by Korean firm Samsung.
The device is said to feature a magnetic docking keyboard that transforms the Series 5 Hybrid into a "traditional clamshell laptop", similar to the Transformer Prime launched last year by Asus.
The laptop does not feature any additional battery space, but Samsung claims that users will get up to 10 hours of use from the tablet.
It will run Windows 8, Microsoft's much hyped new touch-enabled operating system.
According to PC Pro, the Series 5 Hybrid will come in two versions - one with Intel's new 32nm Atom 'Clover Trail' processor, and another with a more powerful Core iX processor.
As the slate will not be based on ARM chips like the Galaxy Tab 10.1, but rather X86 PC, it will run the full version of Windows 8 and not the RT version, noted Engadget.
Due to the hybrid functionality, the device will also come with the S-Pen and S-Memo technology from the Galaxy Note smartphone-tablet product, enabling users to write notes and drawings directly on the 11.6-inch panel.
The Series 5 Hybrid is said to be "early work in progress", and Samsung representatives told PC Pro that the magnetic docking mechanism would be strengthened in the final production units.
Exact technical specs are not known, but it is understood that the machine will come with Micro SD, Micro HDMI, USB 3 and a 3.5mm headphone output, along with a 2-megapixel front-facing camera and 8-megapixel rear camera with flash.
However, Samsung stressed that all these specs are subject to change.
Last week, Microsoft launched the latest preview of Windows 8, bringing various improvements to what the firm is billing as the "most important piece of work we've done".
Samsung has also confirmed plans to release its Series 7 All-in-One touchscreen PC with Windows 8, presumably when the final version of the OS goes on sale in the autumn, three years after Windows 7.
