second battery in x200 ultrabase?

[defor]

Perhaps I've missed this in my searching, but Lenovo is stating that a second battery can be charged in the ultrabase itself...

Integrated battery charger - Lets you power up a spare battery for the road

Does anyone have photos of how this works (I have no ultrabase and am curious)

Also, can one use the system while connected to the UB on both batteries?

ex: 2x 9-cell, etc?

or are they misleadingly referring to the ability to charge a ultrabay battery in the UB?

thanks!
everyone I know seems a bit baffeld by Lenovo's statments as well, and none of us want to shell out the 200$ for an UB jsut to find out it's a misprint or misleading.

The X200 Ultrabase has a pop-out connector on the left side to which the external battery to be charged can be connected. I have not tested if the external battery can power the docked notebook, but that would seem unlikely given the design of the contraption.

sounds reasonable- almost like it's not designed to attach, but more connect- that and toting that configuration around on a lap - somehow i don't think it'd work

if anyone can snap a pic, that's great- if not, regardless, my question is more or less answered.

Thanks!

what about if you put a second battery in the ultrabay? will that work to power the dock and the laptop?
