T400 AC Adapter
The AC adapter for my T400 is badly frayed where it plugs into the laptop. The adapter says "P/N: 92P1105" and "FRU P/N: 42T5000."
I looked for a replacement at lenovo.com but these numbers didn't show any results. In amazon.com I can find one or the other but not both. Which is essential to buy the right replacement? Thanks.
