Lenovo 92P1105 20 V 4.50 A AC Adapter

This Lenovo AC adapter delivers 20 V DC at 4.50 A for compatible notebooks. It is manufactured by Lenovo Group Limited under part number 92P1105. The unit comes in a multicolor finish and is supplied in new condition.

ThinkPad N100 R60 T60 X60 Z60 compatibility

This adapter suits owners of Lenovo ThinkPad N100, R60, T60, X60 and Z60 models needing a replacement charger. It is not for users whose laptops require a different output voltage or current rating. Buyers with other ThinkPad series or non-Lenovo notebooks should look at a different power supply.

Output fixed at 20 V DC 4.50 A

The single specification that decides fit is the fixed output of 20 V DC at a maximum of 4.50 A. Only notebooks designed for exactly this voltage and current will operate correctly with this adapter. Verify the required ratings on your original charger before ordering.

Questions about this item

Does the 92P1105 adapter use the rectangular 20 V connector that fits ThinkPad N100, R60, T60, X60 and Z60 models?

Yes, this 20 V DC 4.50 A adapter is listed as compatible with those ThinkPad notebooks, which all use the same rectangular slim-tip power plug.

What is the correct order to connect the 92P1105 so the notebook recognises the 20 V supply?

Plug the AC cord into the adapter brick first, then into the wall outlet, and finally insert the slim-tip connector into the notebook; reversing the order can prevent the 20 V handshake.

When should I replace the 92P1105 if the output drops below 20 V or the cable frays near the connector?

Replace the unit if the notebook reports a lower voltage, the brick becomes unusually hot, or the cable insulation shows damage near the slim-tip or AC inlet.
