New X61s -- What's this slot?

[SteveDC]

I forgot what I ordered and it is not on the paperwork. It is under the PCMCIA slot. It is a smaller slot with an indentation for a finger, I guess, at the bottom.

I thought I ordered an express-something slot based on forum discussions. But I bought a Verizon Wireless ExpressCard WWAN adapter and it is too big to fit. I'll return that.

It kind of looks like an SD memory card slot -- it is about that size but I am afraid to try it and fry something.

I see nothing on it in the documentation. Maybe I am confusing T61 features and forum discussions with those on the X61.

It is an SD card slot. I think there should be a light and a label just to the left of it (if you look).
