Toshiba offers to exchange 340,000 batteries

Toshiba has offered to exchange 340,000 notebook computer batteries, but said they do not pose a fire hazard. Instead, defective batteries could unexpectedly cut power to the notebooks, causing users to lose unsaved work.

The batteries, made by Sony, may fail to charge correctly, causing the power to cut off suddenly if the notebook is not connected to a mains outlet, said Toshiba spokesman Keisuke Ohmori.

Reports of lithium ion cells in notebook batteries overheating or catching fire have prompted other computer manufacturers, including Apple Computer and Dell, to issue safety recalls. Dell recalled 4.1 million batteries used in its notebook computers in August, citing a fire hazard, while Apple recalled 1.8 million batteries, warning that they could overheat.

Toshiba's batteries are not at risk of starting a fire, Ohmori said. "There is no such hazardous or related issue," he said.

Instead, Toshiba's problems stem from a defect in the interface circuitry between the battery cells and the computer.

That defect is caused by corrosion, said a spokesman for Sony, the manufacturer of the batteries. An ingredient used in the insulating paper of batteries manufactured between March and May can corrode components in the batteries' charging circuits, causing them to fail, said Sony spokesman Takashia Uehara. The supplier changed the composition of the insulating paper without notice, he said.

Batteries made for other notebook manufacturers also contained the paper, and Sony is working with those companies to see whether there is a problem, Uehara said. He declined to say how many batteries were affected overall.

Toshiba's free battery exchange program covers 11 notebook models sold in Japan, five sold in the U.S. and 12 sold in Europe, including the Tecra A7, Satellite A100, Satellite M50 and Satellite pro M70, Ohmori said. European customers can consult a list of affected computers on Toshiba's Web site.

STYLISTIC Q702

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
