Having told you about a Panasonic ToughPad now onto the really ‘tough boy’ of the group the ToughBook. This is built to withstand environments that you really should not expect a computer to function in, it has even been launched outside a weather balloon and still worked when it came back to earth.

Panasonic Toughbook CF 20

The Panasonic ToughBook CF-20 measures 27x23x3.5cm and weighs 1750grams. The viewable screen is 21.6x13.6cm 2which gives the notional diagonal imperial display of 10.1inches which means you can use the Mobile versions of Word/Excel/Power Point for free. However the screen resolution is higher than the PC norm of 1920x1080 you have 1920x1200 which is WUXGA.

This is a truly multi-function device having at least six modes of use, Notebook, Tablet, Vehicle, Handle, Convertible, Presentation and it’s fully detachable.

Every connection is behind a sealed door that locks out water.

The left side of the base of the unit is DC input, SD Card input, HDMI, USB2 and VGA. The front is clear. The right side has Serial, Optional Connector and then two USB3 ports. The back has a solid semi-circular handle.

Lift the lid and behind the keyboard is a solid release slider to allow you to work with only the 925gram screen.


At the top in the centre of the screen (landscape mode) is a 2MP webcam.

Going around the screen has Ethernet, then behind a single door HDMI, USB3, 3.5mm socket for Audio and a SIM socket. The base has connection to the optional Desktop Docking Station or Car Dock. The right side has a stylus the  DC input and finally the Kensington Lock port. The top has battery indicators. I say indicators as this can use two batteries. The back has the unit’s 8MP camera. The connection is a very solid arrangement to allow reconnection to the keyboard and until the orange indication disappears you are still not docked, having docked you can walk around holding the screen this is rugged.

The keyboard has 83 keys the alpha and numeric keys are 1.5x1.3cm the others are smaller. The left and right side have a .5cm strip and the back has 1.5cm clear. The front has an 8cm strip; the 8x4cm trackpad is mounted 8.5cm from the left and 10cm from the right.

This is the only Windows 10 unit that I have seen than comes with Windows 10 Pro. There is also some Panasonic Settings software.

It is certified to withstand a drop from 120cm. It comes with a three year warranty.

It has an Intel 6th Generation Intel Core m5 vPro processor running at 1.51 GHz. It has 8GB RAM. The eMMC Solid State drive is 217GB when formatted.


Switch on is 12 seconds to Desktop, switch off blanks screen in 2 seconds.

Running streaming video from full to empty got to 5 hours and 40 minutes before auto shutdown. A full recharge from empty when switched off was only 126 minutes. In normal use with care you should get around 12 hours use from the single battery supplied to me.

You have a line of six touch buttons below the screen, A1 starts the Panasonic Utilities, A2 brings up a choice of on screen keyboards, - and + buttons control the volume, next the Windows button and finally the back button. There are then three bright LEDs and finally the on/off button.

Although I was using this unit for most of April and during the first few days I was able to do a number of upgrades I was still with V1511 of Windows, the opportunity to upgrade to V1607 – that most people got in November last year – was only given to me in May, I can only assume that Windows 10 Professional updates come later than Windows 10 Home do.
