My Dell Inspiron M101z has 3 USB ports.

There are two on the right side, one of which is "PowerShare" meaning it can charge devices while the computer is off. I'm not asking about these.

On the left side there is another USB port, but it has 4 extra contacts on the other side of the plastic "tongue". I could almost imagine it being eSATA, but I think the slot isn't big enough.

What is it?

Is it one of these? – Dennis Williamson Nov 3 '10 at 5:13
I find that this laptop comes with 3 USB and no eSATA but you never know. I think some pictures might help in helping you find out what they are. It could just be grounds of some sort. – David Remy Nov 3 '10 at 13:34
