I ordered this product directly sold by Amazon. The adapter has not the mouthpiece for the PC HP DV5. I can understand that it lacks a bit. But I just figured that when the item is sold by amazon was no choice other than to return the object. We can not contact Amazon to seek clarification on this universality. Personally, I would keep this adapter, which suit me for other PC but get or buy if needed tip is missing for my HPDV5.
