Welcome to a Laptop Battery specialist of the IBM Laptop Battery
The ThinkPad X40 is a full 20 percent smaller and 25 percent lighter -- 14 ounces less -- than its predecessor, the ThinkPad X31. For the business traveler, 14 ounces translates into three cell phones; or two digital cameras; or a bottle of water; or a pair of jeans, a sweater and a T-shirt. It also offers a unique battery design capable of providing the longest standard battery life of any leading brand notebook (3), at up to 7.5 hours (4) on select models with the optional 8-cell battery. Mobile users can also combine the X40's unique battery like IBM ThinkPad T22 Battery , IBM ThinkPad T23 Battery , IBM ThinkPad T30 Battery , IBM ThinkPad T40 Battery , IBM ThinkPad T41 Battery , IBM ThinkPad T42 Battery , IBM ThinkPad T43 Battery , IBM ThinkPad T60 Battery , IBM ThinkPad T61 Battery , IBM ThinkPad X20 Battery , IBM ThinkPad X21 Battery , IBM ThinkPad X22 Battery options to deliver all-day computing for people who take their notebooks with them anywhere and everywhere, offering up to 10 hours of optional battery life in a total solution that weighs less than 4 pounds.
"With this new design, IBM ThinkPad support for the highly mobile user is unsurpassed in the industry," said Fran O'Sullivan, general manager, IBM Personal Computing Division. "The new ThinkPad X40 redefines the ultraportable notebook standard for 2004 and beyond. Reducing ThinkPad weight by 14 ounces translates into an entirely different experience for users. It means they can do real computing on demand, wherever they happen to be located."
IBM provides flexibility so users can take advantage of wireless technology via Intel 802.11b, IBM 11b/g, IBM 11a/b/g (5), and Bluetooth Wireless Technology. When used with the IBM Embedded Security Subsystem, along with industry-standard wireless encryption, the ThinkPad X40 provides the most secure wireless computing environment in the industry (6). In addition, all X40 models come standard with a modem, Gigabit Ethernet and Infrared.
Featuring the Intel Pentium-M processor together with enhanced IBM ThinkVantage Design, the ThinkPad X40 sets new standards in mobility and battery life. In addition, select models include Intel's Centrino mobile technology, providing wireless connectivity while helping to deliver high performance and extended battery life.
The ThinkPad X40 also includes innovative new features such as a powered USB 2.0 port, which supports external optical drives without a separate AC adapter, and a new Secure Digital port. The ThinkPad X40 can work with the new optional X4 UltraBase Dock, providing additional expansion options for mobile workers at a combined weight of only 4 pounds. By redesigning the X4 UltraBase Dock for increased functionality, IBM provides the flexibility of converting the X40 into a two-spindle solution that supports UltraBay Slim devices such as additional batteries, added media options, and increased storage capacity. The X4 UltraBase Dock also includes a USB 2.0 hub, power-on button and keylock for added security. The ThinkPad X40 also features a simplified case design allowing for faster and easier service of memory and communications options.
Additionally, the X40 has been designed for greater durability for business travelers, by including IBM's patent-pending hard drive protection technology to help protect people's data. The IBM Active Protection System, similar to the technology used in automobiles to deploy airbags, uses a microchip on the system board to detect system acceleration (such as in a fall) and responds by temporarily parking the drive's read/write head. This rapid response can help prevent some hard drive crashes that occur in some falls, helping to prevent total data loss and ultimately reduce downtime and warranty costs.
