I see this picture which is from a re-manufactured notebook. You know ,in China lots of people import the discarded electronic products ,then use a new crust as a new product. I just want to know what's the port. It must have been used by ThinkPad
I agree with Falcone, I think it is the low profile 26 pin connector for an external floppy drive. Some of the Thinkpads used the 26 pin connector others used a 36 pin connector.
