Sony has quite a reputation for building computers equipped with impressive multimedia capabilities. The VAIO K115Z is a very powerful desktop replacement but its real strength is in editing digital images or video.

It's based around an Intel Pentium 4 M processor running at 3.06 GHz. As this is the notebook variant of the chip, the processor can slow down to conserve power and will often reduce its speed when not undergoing heavy data crunching. Besides, a modern processor like this is powerful enough that you are unlikely to notice any reduction in performance anyway.

There is 512Mb of onboard memory and, unlike many notebooks which use shared graphics memory, this VAIO has a Radeon Mobility 9200 with 64Mb of its own memory. This will make a difference if you are doing system-draining work such as image or video editing.

In our testing the K115Z was quite capable of playing the latest 3D games. The 15in screen is very bright thanks to an anti-glare filter and uses a more powerful backlight. The screen is impressive, particularly for video, but does take a couple of seconds to reach full brightness when switched on.

The size of the screen also means that Sony has been able to install a big keyboard. It's more comfortable to type on than many notebooks and Sony has resisted the temptation to move the odd key around.

It comes with a 60Gb hard disk and there is a recordable DVD drive that supports all formats except DVD-RAM. There is also a Memory Stick slot but, like other Sony products, no other formats of memory card are supported.

Most of the notebook's rear is taken up with air vents for keeping the machine cool. There are all the usual ports and sockets, including USB 2 and mini FireWire (for video editing).

Sony has also included Wi-Fi, which will work with both 802.11b and the faster 802.11g standard. There's a switch to turn this off, which is very useful if you ever need to use the notebook in places where radio transmitters aren't welcome.

There is a very generous software bundle, starting with Microsoft Works 7 for everyday tasks. If you're feeling more creative, a selection of Adobe products are also installed, including Photoshop Album 2 Starter Edition, Photoshop Elements 2 and Premiere 6 LE.

The battery life wasn't that spectacular - just under two and a half hours - and this will decrease if battery-draining tasks are performed, such as DVD playback and video editing. A spare battery like Sony PCGA-BP1N battery, Sony PCGA-BP2NX battery, Sony PCGA-BP2NY battery, Sony PCGA-BP2R battery, Sony PCGA-BP2S battery, Sony PCGA-BP2T battery, Sony PCGA-BP2V battery, Sony PCGA-BP4V battery, Sony PCGA-BP71 battery, Sony VGP-BPS2 battery is supplied, although it can only be charged when connected to the notebook. However, it's very easy to fit.

Overall, despite the fact that this is quite a large and expensive notebook, you do get a system that can hold its own against desktops and there is a very good software bundle. If you have an interest in digital media, the Adobe companion pack gives you most of what you will need.
