Fujitsu-Siemens (FS) is limbering up for the summer season with the unveiling of a three-model professional laptop range, dubbed Esprimo. Don't expect Vaio styling or an Alienware extravagance, because this line means business.

The Esprimo range comprises of the U9200, the M9400 and the top-of-the-range D9500. The U9200 is touted as the most mobile of the trio as it weighs 1.8kg, while the M9400 and D9500 weigh 2.1kg and 2.5kg, respectively.

A range of screen sizes are available across all three 1280 x 800 (WXGA) display models. The U9200 has a 12.1in screen, while the M9400 is a 14.1in machine. The D9500 is a meatier 15.4in model and can be upped to 1400 x 900 pixels (WXGA+).

All three notebooks have optional CPU builds, ranging from Intel's single-core Celeron M450 to the 2.4GHz Core 2 Duo T7700. Each also includes up to 4MB DDR 2 memory running at 667MHz. Graphics come courtesy of Intel's GMA X3100 engine built into its GM965 chipset.

An ExpressCard 54 slot is built in, as is Gigabit Ethernet connectivity and three USB 2.0 ports. A nice addition is a four-way memory card reader for SD, MS, xD and Memory Stic Pro cards.

On the wireless side, users can pick either an Intel Pro Wireless 802.11a/g/n card or Atheros' 802.11b/g minicard. The laptops have 3G connectivity built in too, and Bluetooth 2.0.

The Esprimos can be configured with to 160GB SATA hard drive storage. Additional features include a spill-proof keyboard and a multi-format dual-layer DVD writer.

All three models will be available in Europe from August, with prices starting from €1099 (£743/$1,493).
