Panasonic Toughbook CF-51 semi-rugged notebook

The Captain Scarlet of mobile PCs?

Panasonic Toughbook CF-51Review Panasonic has been making notebooks for a long time, but you may not have come across the Toughbook brand before. The reason for this is that Toughbooks tend to attract a buyer who is more concerned with durability than design and performance. To get an idea of who the Toughbooks appeal to, next time you see a BT engineer working on a junction box in the street, take a look over his shoulder. It's a near certainty that he'll be working on a Toughbook, writes Riyad Emeran.

As the name suggests, Toughbooks are built to be, well, a bit tougher than your average notebook. In fact, the fully rugged units sported by field engineers are built to withstand impact, water, dust and just about any other environmental hazard that mobile computers might be subjected to. But not everyone wants to carry around a large, heavy, metal and rubber clad notebook, no matter how strong it might be. With this in mind, Panasonic created semi-rugged Toughbooks.

The semi-rugged Toughbook may not be impervious to water, or be able to withstand a car rolling over it, but it does give the user a bit of extra peace of mind without being too oversized or heavy. The CF-51 is Panasonic's latest semi-rugged notebook and at first glance it doesn't look too different from any other notebook. OK, so it's a little larger than most, and weighs more than some, but on the whole it just looks like a notebook.

But it's what's beneath the skin that sets the CF-51 apart. To start with both the base and lid are reinforced with magnesium alloy to protect the screen and internal components. This allows Panasonic to guarantee that the CF-51 can withstand a drop from a height of 30cm. That might not sound like much, but on the occasion when you drop an expensive piece of kit, you'll notice that it seems to take an eternity before it hits the ground, probably never to work again - quite simply, any kind of shock protection is a good thing.

Of course, for a notebook to remain operational after being dropped, the hard disk needs to be protected. To facilitate this, the hard disk in the CF-51 is cocooned in an impact and vibration absorbent enclosure - it's also easily removable in case you're very paranoid about losing your data. In fact, pretty much everything is modular in the CF-51 - push a little switch and the hard disk caddy slides right out of the front, push another one and the battery will slide out, while the optical drive will slip free from the chassis with similar ease. So, no need to get out the screwdriver for this machine then. Well, unless you want to add memory to the free SO-DIMM slot.

Apart from the matt silver lid, the rest of the notebook is finished in black - not particularly inspiring, but not offensive either. Lifting the lid reveals a fairly standard keyboard and touchpad layout. The keyboard is a bit of a mixed bag - most of the keys are a decent size, but bizarrely the Return key is tiny. I always find it strange when a manufacturer decides to reduce the size of the Return key, since you really don't want to be missing it when you're typing at full speed. Likewise, the Backspace key has also been reduced - another often used key that's been made harder to strike. On the plus side, the cursor keys are set apart from the rest of the keyboard, and the Ctrl key is in at the bottom left, right where it should be.

The touchpad works well enough and is positioned far enough from the Spacebar to avoid accidental cursor repositioning.

The screen is a superb example, sporting an impressive 1600 x 1200 resolution. This is more desktop real estate than the majority of desktop monitors provide and certainly makes for a very pleasant working environment. There's no fancy high-contrast coating on this screen, but then a Toughbook isn't really meant to be used for gaming or movie watching. As notebook screens go, this is one of the best I've seen, coming second only to the handful of 1920 x 1200 widescreen examples I've encountered.

Inside the CF-51 is a 2GHz Pentium M CPU backed up by 512MB of memory. As already mentioned there's a free SO-DIMM slot, so you can augment the memory post-purchase without the need to discard any modules. There's an 80GB hard drive which should keep you happy for a good while.

Being a Centrino-branded machine there's obviously an Intel Wi-Fi adaptor thrown in, and it's good to see that Panasonic has gone for a top-end card that supports 802.11a, b and g. This complements the integrated gigabit Ethernet adaptor. Bluetooth is conspicuous by its absence, however.

Taking a look around the chassis, you'll see that the right side is dominated by the DVD-ROM/CD-RW combo drive. I don't often see these anymore, with pretty much every notebook I come across fitted with a DVD writer these days. The front is adorned only by the headphone and mic sockets, battery and charge indicator lights, and the modular hard disk caddy.

On the left there are two Type II PC Card slots, two USB 2.0 ports, a four-pin FireWire port and the power socket. Surprisingly, the rear sports the most features, despite the fact that most notebooks these days are pretty sparse at the back. Here you'll find serial, parallel and D-SUB ports, a modem socket, an Ethernet port and a PS/2 port. Clearly Panasonic feels that legacy ports are important to Toughbook users, who may have specialist equipment that needs to be connected via archaic serial ports.

Performance-wise, the CF-51 turned in some pretty good numbers. Running MobileMark turned in a battery life of over three and a half hours - not the best I've seen but definitely respectable. Running a DVD movie turned in a time of just over three hours, but I doubt that too many Toughbooks would be used for such duties.

The overall SYSmark 2002 score of 225 isn't too far off the 241 scored by the similarly specified Samsung X50, which isn't a semi-rugged device. Ultimately, the CF-51 will handle pretty much anything you're likely to throw at it, which it good since the high resolution screen lends itself to multi-tasking.

This version of the CF-51 is so new that it's not actually on sale yet, but Panasonic quoted me a street price of £1551. That's not bad considering what you're getting, but it's obviously more expensive than a similarly specified non-rugged notebook. With a machine like the CF-51 you've really got to ask yourself if you're willing to pay for the comfort of knowing that your notebook can withstand the odd knock, or even drop. If you are worried about both your investment and your data security, then the CF-51 will look attractive.


If you're worried that you might damage your notebook, the idea of a semi-rugged device makes sense. The Toughbook CF-51 has a lot going for it, especially the excellent 1600 x 1200 display, although the bizarre shrunken Return and Backspace keys are a concern. And the absence of Bluetooth is a real disappointment. Of course, you can find a regular notebook with a better specification for less money, but it comes down to your priorities - and how clumsy you are, I guess.
