Title: NOT for HP dv7 17-inch laptop
Review: It's HP's fault, not the manufacturer of this product, but it doesn't matter. It won't work for your 17-inch dv7 laptop.HP originally sold the dv7 with an underpowered 65-watt adapter. The HP replacement adapter is 90-watts. No 65-watt replacement adapter will work. Order a 90-watt adapter for a different model, or give the ******** at HP $70 for their replacement (which is 90-watts). HP should have recalled them. I have gone through 1 12-volt car adapter, and 3 65-watt replacement adapters for mine, but none work. For all, the computer says, "plugged in, but not charging" and the battery quickly dies. Save yourself a lot of headache and expense, and just buy a 90-watt adapter for your 17-inch laptop.Here is the HP original equipment link:Here is the HP replacement parts link:Note how the original equipment has a 65-watt ac adapter, but the HP replacement part is 90-watts.Here is what you really need:HP 90W Smart Pin Dongle AC Adapter (KG298AA)
