Fujitsu Siemens today admitted that a battery defect in its Amilo notebook range could cause the units to overheat and possibly catch fire.
"In some batteries there might be a defect which can cause the battery cells to overheat with a risk of fire," the company warned.
Fujitsu Siemens has implemented what it describes as a "proactive exchange programme" after receiving a "very limited number" of customer reports of a defect in the batteries.
The company recommends that on specific models, including the Amilo A, M and Pro V2020 notebooks, customers should stop using the batteries immediately and operate the device with the AC power adapter only.
Fujitsu Siemens claims to have received only four reports of batteries overheating from a possible 250,000 units. The firm stressed that there are "no reports of injury at time of release".
The defective batteries have been shipping through distributors, resellers and retail stores since October 2004. Fujitsu Siemens also warned that the fire-risk batteries may have been sold separately as a second battery source.
To identify whether a battery needs to be replaced, customers should remove the battery from the computer and view the battery label. If this has a number ending with G1L1, the battery should be exchanged. If a battery does not have this specific number ending, it is not dangerous.
Fujitsu Siemens will provide a replacement battery free of charge. A special website has been set up to assist customers with the exchange programme.
"Customer satisfaction and safety is our primary goal," said Fujitsu Siemens spokeswoman Amy Flécher.
"This proactive battery exchange programme is important to Fujitsu Siemens and we want to make sure that we reach as many of our customers as possible with this communication.
"We stand behind the quality of our products, and our priority is to meet the expectations customers have of our company."
