Power Connector
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. |

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.

AC Adapter PN 0A36227
- ThinkPad W520
The W520 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 into the W520 thinkpad in one particular orientation. The extra knob prevents one from using the W520 AC adapter on any other Thinkpad. However, the W520 Thinkpad does accept other AC adapters (all 20V AC adapters except the one for the W700), though not all supply enough power.
