I need a new power adapter for my laptop. The original specs say 19v, 45w, 1.74a. For a replacement do I need those exact specs? Or, if there is wiggle room, where and how much? I have seen more 65w and 90w adapters than 45. One 65w adapter I saw did specifically say 'compatible with 45w'.
Also, for various reasons I can't get mail, so I need to buy an adapter in-store. Amazon, ebay, and any sort of delivery are out. All the big box stores (WalMart, BestBuy, etc) I have checked have adapters, but not for in store pick-up, let alone in stock in store. Are there any smaller retailers in Phoenix, specifically Paradise Valley area, that sell this stuff?
I will have a great deal of trouble and expense getting a manufacturer part and I can't actually afford it,
