Revision as of 00:50, 24 August 2013

Over time, different ThinkPads have used different power connectors. You can use a higher Amperage rated power supply then your ThinkPad needs, as long as the physical connector is correct. But you should not use a lower Amperage power supply on a ThinkPad needing more Amperage. Doing so will overheat the power supply, and might cause issues such as screen flicker.

Hint:
In case you cannot find your Model ThinkPad listed, or you wish to double check, you can find the required power information on a label on the bottom of your ThinkPad
NOTE!
The Amperage's listed below are the OUTPUT values for the AC adapter, which should be equal or greater then what your ThinkPad requires

All current Thinkpads require 20 Volt DC input. See also the official Lenovo page for power adapters.

10.5 V, 1.0 A Power

15 V, 2.0 A Power

6.3 mm outer, 3.0 mm inner diameter.

This AC adapter has the same diameter as the usual 20V AC adapters, but there is an extra plastic knob on one side of the connector. It is not round any more, that is, you can only plug it in one particular orientation. The extra knob prevents one from using the AC adapter on any other Thinkpads.

W700 Coax connector

6.0 mm outer, 3.0 mm inner diameter.

Will someone with an actual unit in-hand, please confirm the size?

The W700/W700ds AC adapter plug has a different diameter than all other 20 Volt AC adapters. You cannot plug in a different AC adapter into a W700-series Thinkpad nor can you use the W700 AC adapter on a non-W700 Thinkpad.
