I had an ASUS laptop, and the original ac adapter had frayed and would not charge. ASUS gave me the info I needed to find another. When I received it it STILL wouldn't charge. So I took it to Staples Tech and turns out my motherboard had fried. So even though this looks fairly beat up, it has never been used. Its' been transported to fro and on my desk. I no longer have a use for it, maybe you do.
