I have a very important user, who has a latitude Z600 laptop, and the cables to her power adapter are becoming frayed and cannot be used for much longer. I need to get her a replacement. I called DELL, as well as using their support website (based on the service tag and model), and they recommended a 65 watt power adapter to us. We purchased it, but when the user tried it out, she says it gave her a warning that said to use the power adapter that came with the laptop. I called DELL back, but they don't have any other recommendations.
Here is the part number for the adapter we purchased:
Manufacturer Part# : TR82J | Dell Part# : 331-0536
I need to get her a replacement working AC adapter, and I do not want to risk harming her system with the 65 watt replacement DELL sold her, if the laptop is giving a warning. Is there any other route I can take to resolve this? As I said above, she is an important user, and she would want more than simply making use of electrical tape. Please send any ideas.
