Questions about this item

Will the 11x5mm plug on this 135W adapter fit the charging port on my older ThinkPad that used the ADL135SCC2A part?

Yes, the 11x5mm connector matches the ADL135SCC2A and other listed part numbers, so it will fit the same port on compatible ThinkPad models.

How can I confirm the adapter is delivering the correct 20V 6.75A output after I plug it in?

The laptop should show it is charging at full speed and the battery icon will indicate AC power; a multimeter on the plug can also verify 20V output.

Does the package include both the 135W adapter brick and a mains power cord for my region?

Yes, the box contains one AC adapter and one power cord; the cord type matches the EU, US, UK or AU plug option you select.
