==Problem Description==
In March 2005 IBM reported that some 56W adapters manufactured by Delta Electronics Inc. may suffer overheat, resulting in melting of adapter housing and charring of the circuit board inside the housing.

Only one AC-adapter part number is affected: '''P/N 02K6549''' ([http://www-307.ibm.com/pc/support/site.wss/56587_56w_ac_adapter.jpg See photograph here]). No other IBM ThinkPad AC adapters are affected.

==Affected Models==
Laptops that ''originally'' carry this AC-adapter are:
*ThinkPad {{I1200}}, {{I1210}}, {{I1230}}, {{I1250}}, {{I1260}} <tt>(Machine Types 1161, 2666, 2667)</tt>
*ThinkPad {{I1300}}, {{I1330}}, {{I1370}} <tt>(Machine Types 1171, 2666, 2667)</tt>
* ThinkPad {{I1420}}, {{I1421}}, {{I1422}}, {{I1441}}, {{I1442}}, {{I1450}}, {{I1451}}, {{I1452}}, {{I1460}}, {{I1472}}, {{I1480}}, {{I1482}}, {{I1483}}, {{I1492}} <tt>(Machine Types 2621)</tt>
* ThinkPad {{I1540}}, {{I1541}}, {{I1542}}, {{I1552}}, {{I1560}}, {{I1562}}, {{I1592}} <tt>(Machine Types 2621, 2651)</tt>
* ThinkPad {{i1720}}, {{i1721}} <tt>(Machine Type 2627)</tt>
* ThinkPad {{240}} <tt>(Machine Type 2609, 2612)</tt>
* ThinkPad {{390}} <tt>(Machine Types 2624, 2626)</tt>
* ThinkPad {{S30}}, {{S31}} <tt>(Machine Types 2638, 2639)</tt>
(but you ''may'' be also using this 56W adapter with other ThinkPad models!!).

==Solution==
If your AC adapter is P/N 02K6549, IBM will replace the AC adapter, free of charge; just follow this link: [http://www.adapterprogram.com/ibac/ IBM AC Adapter Replacement Program].
