Toshiba Unveils Laptop with Water-cooled Chip

SAN MATEO (04/17/2000) - Toshiba America Information Systems Inc. introduced its new Portege 3440CT, a 0.75-inch-thick laptop computer which sports two significant features: a water-cooled processor and an optional Lithium Ion battery "slice" that provides up to nine hours of battery life, according to Steve Andler, the vice president of marketing at Toshiba's portable systems group.

The advanced "super cooling heat pipe" is a specific device that attaches directly to the processor. The cooling system uses low-pressure water vapor to displace heat throughout the magnesium chassis of the computer, according to Andler.

This is the first water-cooled technology to be introduced into laptop computers, a product that industry analysts expect to only get hotter as wattage requirement rise to 20 watts by the end of the year.

Adding less than two pounds to the system's 3.5-pound weight, the optional 1-inch Lithium Ion battery slice attaches at the base of the laptop, adding up to nine hours of extended battery life past the 2.5 hours provided by the main battery.

Instead of incorporating Intel Speedstep technology as a power-saving feature, Toshiba has opted for a lower-voltage 500MHz Intel mobile Pentium III processor.

Other features include a 11.3-inch polysilicon TFT (thin-film transistor) display, expandable 64MB of PC100 SDRAM (synchronous dynamic random access memory), and an S3 Savage IX graphics accelerator.

Estimated single unit pricing for the new Portege 3440CT starts at US$2,499.

Also introduced from Toshiba today, the consumer-targeted Satellite 2210XCDS and 2210CDT laptop computers, which will retail for $1,399, and $1,699, respectively.
