Toshiba Portégé R830 review

The Portégé R830 is the latest ultra-portable laptop from Toshiba. Although the R830 looks physically indistinguishable from previous Portégé Rx30 models, it's actually a noticeable improvement in a couple of crucial areas.

Its battery lasted just under nine hours in our light usage web browsing test which is one of the longest scores we've seen.

The R830 weighs just under 1.49kg which is all the more remarkable since it has a built-in DVD writer, which isn't always a given on especially light ultra-portable laptops. This low weight makes it easy to carry around all day, but it still feels well-made. The black metallic lid and wrist rest look classy. While the lid flexes under pressure more than we'd like, the base feels very sturdy and robust.

A lightweight and sturdy laptop is of little use if the battery life is too short for extended periods of use away from a power socket. Thankfully the R830 doesn't disappoint – its battery lasted just under nine hours in our light usage web browsing test which is one of the longest scores we've seen and is more than long enough to last a transatlantic flight.

We suspect this lengthy battery life is, at least in part, due to the R830's new more power-efficient Intel Sandy Bridge processor. Toshiba has chosen a standard voltage 2.5GHz Core i5 2520M processor instead of a low-voltage variant which would have been even more power thrifty but at the expense of processing power. The 2520M paired with 4GB of RAM fared well in our Windows applications benchmarks scoring 60 overall which is fast for an ultraportable laptop.

Even though its applications performance is commendably fast, the underside of the R830 didn't become uncomfortably warm during use. However, it would be wise not to block the cooling vent which expels hot air out of the side of the laptop. This effective cooling is almost certainly due, at least partially, to the cooling fan which is almost always audible. It's not especially loud, except when the laptop is churning through more demanding work, and although it is annoying we got used to it after a while. At least it isn't any louder than other laptops we've seen.
