Need W530 power plug
Posted: Fri Aug 23, 2013 4:26 pm
Does anyone know where I can get a couple of W530 power plugs from?
I have some perfectly adequate power supplies that use conventional "coaxial" power plugs, but the two notches in this one make it special. Simpler for me to change the plugs than to buy new power supplies.
Unless the W530 can be modified with a standard 20v power socket in it?

Who knew, they used pull-up resistors for signaling in "dumb" power cords?
Although, I'd still like a source for extra plugs with easily accessible signal resistors.
