Asus Zen Ai0 power adapter (North Laine BN1)

Has any kind person out there got either an Asus Zen Ai0 19volt power adapter they dont need OR could someone possibly lend me one very briefly. This is only to test one of my most recent street rescues, a Zen all-in-one PC (or imitation Imac ) which of course had no power adapter with it. I'm a retired computer engineer and whilst I have lots of similar laptop adapters none of them are suitable in this case, and I dont want to spend money on an adapter if the machine itself is likely to be broken up for the parts alone. Any offers of help gratefully received.....
