As a generic-looking 15.6in laptop, the Advent Sienna 710 has curved corners and gently tapering edges which do a good job of disguising its rather thick plastic housing.

However, despite a rather unassuming appearance, the Advent Sienna 710 comes with the fastest and most powerful processor of the group – Intel’s 2.66GHz Core i7-620M.

However, while the Advent Sienna 710's dual-core Core i7-620M delivers excellent performance – we saw an astonishing 118 points in the WorldBench 6 real-life speed test – it also has a considerable thirst for power.

The Intel Core i7-620M has a max TDP of 35 watt, which means there's a considerably amount of wasted heat to deal with. However the physical design of the Advent Sienna 710 notebook relies on a very large grille and fan system on the underside. A bright yellow sticker warns against bodily contact, and more specifically, against using this laptop on your lap...

As it happens, you probably won't want to venture too far from your desk anyway as the Advent Sienna 710's battery life is quite frankly rubbish at just over two-and-a-half hours. Combing a power-hungry CPU with a puny 32Wh battery is really asking for trouble.

If you fancy the odd bit of gaming, then the Advent Sienna 710 will disappoint too as there’s no discrete graphics processor provided, forcing you instead to rely on the integrated Intel GMA HD graphics found on the CPU. Even old games such as FEAR judder around at an unplayable 17 frames per second at Maximum detail settings.

If the Acer Aspire TimelineX and Apple MacBook are about portability, freedom and a fun digital lifestyle, the Advent Sienna 710 is most definitely about staying in and getting on with some work – which is a shame as that means no-one will be able to see your customisable laptop cover (available for an additional £29.99).

Ergonomically, the Advent Sienna 710 is pretty standard fare, providing a Scrabble-type keyboard with a numeric keypad and a couple of custom buttons in a tidy but ultimately slightly unimpressive body.

OUR VERDICT

At £699, the Advent Sienna 710 is a relatively inexpensive way of wielding some fearsome portable computing power, but with its battery life and heat issues, along with comparatively poor graphics performance and high fan noise, we can’t recommend it for use on the move or away from a mains outlet for any length of time.
