IBM is voluntarily recalling approximately 553,000 56 watt AC adapters made for use with notebook computers shipped worldwide between January 1999 and August 2000. No other AC adapters are affected by this recall notification.
IBM has received reports that some of these adapters have overheated, resulting in melting of adapter housing and charring of the circuit board inside the housing. None of the incidents has resulted in reports of personal injury. There have been some reports of minor property damage. IBM voluntarily reported this information to the U.S. Consumer Product Safety Commission (CPSC) and is working in cooperation with the CPSC on this recall. These adapters were manufactured for IBM by Delta Electronics Inc.
While awaiting a replacement adapter from IBM, customers should unplug the adapter from the wall electrical outlet when unattended. If an adapter shows any sign of overheating, customers should immediately unplug the adapter at the wall electrical outlet and notify IBM.
How to determine if your AC adapter is affected
These AC adapters were shipped worldwide primarily with ThinkPad i Series notebook computers and ThinkPad 390 and 240 series notebook computers, and a limited number of IBM ThinkPad s Series notebooks in selected countries in Asia Pacific outside of Japan. Some customers may be using these adapters with different ThinkPad models. The adapters can be identified by the hollow 3-pin male connector on the adapter brick that accepts the 3-pin female AC cord and the part number located on the label on one side of the adapter brick.
The AC adapter brick is a small rectangular black plastic box. On one end there is a permanently attached wire that connects to the computer through a round connector, and on the other end, there is a detachable cord that will plug into an AC outlet.
The adapter brick is approximately 2.7 cm x 4.8 cm x 11.3 cm in dimension. The label will contain the following part number numbers: 02K6549. No other IBM ThinkPad AC adapters are affected.
