Applications
This adapter is designed for IBM ThinkPad laptops that use a 16V DC barrel-plug power input, a standard common across many ThinkPad T, R, and A series models from the early-to-mid 2000s. During that era, IBM ThinkPads used a proprietary yellow-tipped barrel connector and a 16V supply rail before Lenovo (which acquired IBM's PC division in 2005) later transitioned to the slim-tip connector standard. The 92P1021 FRU number identifies it as a field-replacement part in IBM's service catalog, meaning it was the authorized replacement adapter for depot and warranty repair. The universal 100–240V input makes it compatible with AC mains supplies worldwide. Buyers typically seek this adapter for ThinkPad legacy system maintenance, spare/replacement use, or as a travel adapter for older IBM-branded ThinkPads still in service.
This IBM 92P1021 ThinkPad Laptop AC Adapter has been inspected and appears to be in good used condition. The housing is intact and the yellow-tipped DC barrel plug and figure-8 AC inlet show normal wear consistent with regular use. No cracks, fraying, or significant cosmetic damage are visible.
