Fujitsu Computer Systems on Tuesday unveiled its new LifeBook S6510 and LifeBook S7210 notebook computers with lighter components specifically designed for traveling professionals.

The LifeBook S6510 weighs four pounds, has a 14-inch screen, and measures less than two inches at its thickest. Additionally, it's equipped with a spill-resistant keyboard and Fujitsu's Shock Sensor hard drive protection system.

Even though the LifeBook S6510 is designed for mobile professionals, the laptop can't go a full day on a single charge. But the battery life can be extended from 4.5 hours to 6 hours with a modular bay battery.

The LifeBook S7210 weights 5.2-pounds and also features a 14-inch screen and a thin-and-light design. It offers a slightly longer battery life of 6.5 hours with an extended battery that can be placed in the modular bay.

Both the LifeBook S6510 and the LifeBook S7210 contain an Intel Core 2 Duo processor and share other features, such as an integrated Web camera for video conferencing, a biometric fingerprint swipe sensor, an embedded Trusted Platform Module, and a theft-deterrent security panel. For additional security, the LifeBook S7210 comes with a smart card slot.

Users have several options to choose from when it comes to the laptops' connectivity, including a modem, Gigabit Ethernet LAN, Wi-Fi, and Bluetooth.

The LifeBook S6510 starts at $1,529 and the LifeBook S7210 starts at $1,329. Both are immediately available for sale.

Fujitsu last month on introduced the LifeBook A6110, targeting mobile professionals who are looking for a low price point and functionality. The 15.4-inch LifeBook A6110 starts at $849 with a $50 rebate. It's equipped with an energy-efficient Intel Core 2 Duo processor, shock sensor technology, a biometric fingerprint swipe, and several wireless connectivity options.
