IBM Japan unveiled a new ThinkPad hp 498482-001 battery, hp 497695-001 battery notebook computer that can automatically shift its power source from an AC adapter to a stored battery, the company announced Tuesday.
The ThinkPad R31 includes a peak-shift-control program that allows electricity to be used evenly throughout on-peak and off-peak times. Usually when a PC is connected to an AC adaptor, it always uses power from the adaptor. With the ThinkPad R31, users can set a time for the computer to switch its power source to an internal battery such as IBM 08K8195 Battery, which has been recharged during off-peak hours, says Yuko Takeuchi, a spokesperson for IBM Japan.
The Think Pad R31 is the first result of a project that IBM Japan started last March with Kansai Electric Power, Tokyo Electric Power, Sanyo Electric, and Matsushita Battery Industrial.
The purpose of the project was to decrease the volume of electricity used for PCs in offices at peak time, an IBM Japan statement says.
Power Protection
During the summer in Japan, many offices turn on air conditioners in the afternoon, causing dramatic increases in electricity consumption. Power companies have been looking for ways to avoid these peaks, according to the statement. Using stored battery power in the office during the day can ease electricity costs and gateway m-6848 keyboard, gateway m-6750 keyboard protect the environment, the company says.
From July to September last year, IBM Japan, KEPCO, and TEPCO conducted a trial using the peak-shift-control program on their PCs. The trial showed that by charging the PC battery at night when demand is low and then using that stored power during the day, they were able to decrease carbon dioxide production by 4 percent to 16 percent, according to the statement.
IBM Japan also calculated that if the 1200 notebook PCs in its Tokyo headquarters were equipped with the peak-shift-control program, it could save $1,511 a year, the statement says.
Sanyo Electric and Matsushita Battery have been researching the effects on a battery of being repeatedly discharged and recharged, and will keep working on a longer-lasting battery, the statement says. Currently, the ThinkPad R31 can be used for 2.3 hours by a recharged battery, and once the battery runs out it automatically starts recharging again, Takeuchi says.
Coming to the United States?
Of 12 ThinkPad R31 models unveiled, the C5J and 48J include the peak-shift-control program. Both include a Celeron 1.06-GHz processor, 128MB of SDRAM, and a 20GB hard drive, and are equipped with an ethernet interface. In Japan, the C5J with Windows XP operation system will be rolled out on February 15 at $1,350, and the 48J with Windows 2000 will be rolled out on March 8 at the same price, the statement says.
The new R series models are already sony vgp-bps13/q battery, sony vgp-bps13/s battery out in the U.S., Takeuchi says.
The company will distribute the software program to C5J and 48J customers for free, but it is available only in Japan, Takeuchi says.
