The 1.25 kilogramme Nokia Booklet 3G is powered by an Intel Atom processor, and features include an aluminium chassis, 3G/ HSPA and Wi-Fi connection access, an HDMI port for HD video out, a front facing camera for video calling, integrated Bluetooth and an SD card reader, as well as integrated GPS.
The Nokia Booklet 3G is to be formally launched at the Nokia World event in Stuttgart, Germany on September 2.
The world's top cellphone maker's share price rose 1.7 percent on the news that is entering the fiercely competitive laptop market.
A previous Nokia attempt to expand beyond cell phones, a "tablet" computer that runs non-Windows software, has not been a mainstream success. PCs were among the wide range of products that Nokia manufactured before it became a cellphone powerhouse. It sold off the computer division in 1991.
