If choosing the rough and tumble road is your preference, Panasonic's Toughbook range are the only notebooks that will be able to keep up. TechSmart checks out the CF-31 and CF-19.




The Panasonic CF-31 is equipped with a 13.1" XGA touch-screen display with Panasonic CiruLumin technology. LED backlighting ensures a clear and bright display. It is rated at a bright 1100 nit.

The Panasonic CF-19 features a 10.4" sunlight-viewable XGA Active Matrix (TFT) colour LCD display, fully viewable even in direct sunlight. The display is dual touch, meaning it supports a touch-screen and digitizer, plus the screen can be adjusted to turn the device into a tablet PC.


The Toughbook 31 makes use of the powerful Intel Core i5-540M vPro processor rated at 2.53 GHz, with Turbo Boost functionality taking it up to 3.07 GHz.

The Toughbook 19 comes equipped with an Intel Core i5-520UM vPro processor with a clockspeed of 1.2 GHz and Turbo Boost taking it up to 2.0 GHz.


Being sturdy is paramount in a device such as this, so Panasonic has armed the CF-31 with a shock-mounted 250 GB hard drive with a quick-release option for easy drive swapping.

The Toughbook 19 faces bumpy terrain and accordingly is equipped with a sturdy 160 GB super fast SATA hard drive which is shock resistant and can withstand drops of up to an amazing 1.8 m.


The Toughbook 31 as standard sports 2 GB of DDR3 SDRAM which is expandable to up to a powerful 6 GB.

The CF-19 supports 2 GB worth of DDR3 SDRAM as standard and this can be upgraded to a maximum 4 GB.

Dimensions and weight

Measuring in at 292 x 302 x 73 mm, and weighing a solid 3.6 kg, the CF-31 isn't the smallest notebook around. But rugged is the name of the game and we're sure you can handle that extra strain.

At 271 x 216 x 49 mm, the CF-19 is a bit smaller than its counterpart and also weighs less, coming in at only 2.3 kg.


Of course, the most important aspect on a Toughbook is its durability. The CF-31 is certified by military standards for drop shock protection with MIL-STD-810G and IP65 certification, while this fully-rugged notebook also has a magnesium alloy handle and reinforced locking port covers for extra protection.

The rugged CF-19 passed the IEC529 water resistance test and features a double waterproof structure for tight water and dust-proofing. It can be dropped from 180 cm and passed the military MIL-STD 810G vibration resistance test and IP65 certification.
