This explosion wasn’t sparked by terrorists—in all likelihood just a damaged battery. But it has at least one Canadian computer industry analyst riled.

Carmi Levy, senior analyst at Info-Tech Research Group, has called on regulatory bodies and vendors to conduct more rigorous battery testing following reports that a laptop manufactured by Dell exploded in Osaka, Japan.

Levy says the incident serves as a warning about potential threats—including a possible airline tragedy. "Everyone worries about explosives being taken covertly on board planes, but what about the average laptop that could be just as dangerous?"

Recently, The Inquirer carried several pictures of a laptop that burst into flames during a business meeting in Osaka, Japan.

Witnesses said they heard several popping sounds from the machine before fire shot out. Luckily, the computer was on a table and no one was attending to it at the time.

No injuries have so far been reported, but Levy said regulatory bodies and manufacturers need to make a concerted attempt to solve these issues rather than using recalls as a Band-Aid solution.

Dell spokespeople say the case of the exploding laptop is an isolated incident.

"We have not had any indication that there is a broader trend beyond what happened in Japan," said Wendy Gottsegen, corporate communications manager for Dell Canada. "We are carrying out forensic tests on the laptop, and so far we do know the fault is with the battery cell."

On several past occasions, Dell and rival IBM have issued battery and adapter recalls following reports of overheating or burning laptops.

However, Gottsegen said there has been no similar announcement at this point, and current Dell quality checks are adequate. "We remain committed to quality and product safety, and our standards are among the highest in the industry."

Recalls related to computer batteries overheating have been issued by at least three computer equipment manufacturers within the past year, according to Levy.

Hewlett-Packard (HP) announced a recall of some 15,700 HP and Compaq notebook computer batteries in April this year after 20 reports of batteries overheating. Dell announced a recall of about 22,000 of its notebook computer batteries in December 2005. And Apple Computer recalled 128,000 batteries shipped in its PowerBook G4 and iBook G4 laptops in the spring of 2005.

In 2004, IBM recalled 225,000 alternating current (AC) adapters for ThinkPad notebooks after reports that overheating caused some units to burn circuit boards and melt metal housings. The adapters were manufactured by Delta Electronics of Taiwan.
