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. |

TIP: As these 4-pin PSUs are getting more rare and more expensive, a cheap solution if you don't have one is to adapt a universal 19-20V laptop PSU with a barrel connector. This isn't ideal if you're relying on the Thinkpad for some critical old business application, but it's fine if you're just a tinkerer playing with an old one off eBay for example. Only the "+" and "-" connections (top-right and bottom-right looking into the connector on the back of the laptop from the back of the laptop) are required for basic operation, so that's all you need to adapt. Get an extension lead for your barrel connector - e.g. 2.1mm - and cut it in half. Discard the plug half. Get a "Mini JST" plug with flying leads, commonly used to power model helicopters etc. This is the plug that I've found will fit over the + and - pins. Wire the two together so that the red wire on the Mini JST is soldered to the centre contact wire on the barrel connector extension (socket half).
ALWAYS double check the polarity when plugging in your custom modded connector, since it's possible to get it the wrong way round.

170W 8.5 Amps
AC Adapter PN 0A36227 (US) and PN 0A36231 (EU)
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.
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.

slim tip
Lenovo introduced a new power connector in 2012. This connector is standard in all new models since late 2013 product line. It is rectangular, close in size to USB A connector, and it has a signal pin in centre. A conversion cable for 20V barrel plugs exists (ASM 0A36037; FRU 03X6261).
