A:Answer Thanks, Paul. I had the same issue with the small print on the adapter. I finally resorted to using a magnify glass to get the part number -- P/N 86066-001. I was still unable to find it anywhere online, though. I sent a note to HP but haven't heard back from them yet. If I do, I'll let you know. Thank you and I'm glad you're enjoying your Spectre x360. I'm really impressed so far, too.
