+An aftermarket plug converter is available, alone and in a set, which fits IBM's hexagonal inlet.  It is meant to be used with an Universal AC Adapter (of cheap ''China Special'' variety).  It is not safe to use.  In this converter, both '''G''' and '''-''' are wired to the outer shell of the barrel connector, and both '''S''' and '''+''' are wired to the centre pin of the barrel connector.  In some ThinkPads (specifically {{760E}}), '''S''' and '''-''' pins are connected to each other.  This plug will make a short circuit in such a ThinkPad.
-WARNING: do NOT use this adapter, it has two + and two - connectors, which will cause a short in your laptop.
+{{QUOTE|kishy|forum.thinkpads.com|Internal to the ebay DC port adapter, the (G) and (-) terminals have continuity, and the (S) and (+) terminals have continuity.  Therefore, if you connect the ebay port adapter to the laptop, you are shorting positive to negative.}}
