Lenovo W530 to P50 power tip adapter?

Does anybody know if they make or where to get an adapter so I can use a 170W power cord that has the W530 round tip with slots in a P50 with the square power slot?

Re: Lenovo W530 to P50 power tip adapter?

I believe there is no such thing.  The laptop's power circuitry identifies the power supply by checking the resistance between the signal pin (center) and ground.  First, none of the adapters available pass through the signal pin.  Even if you could find an adapter that passes it through, it wouldn't work.  The round tip on the W530 uses 1500 ohms for a 170-watt adapter.  The slim tip (rectangular) tip for the P50 uses 1900 ohms.
