To remove the base cover you need only unclip the external battery pack, then unscrew 8 screws. No messing with the motherboard or monitor. Plus, the Intel card @Juan posted a link to sells for around $30, which is comparable to any external USB interface.
I might try the same, as the drivers for Intel cards are quite mature IIRC.
@Matt, @Juan
This page suggests you have to remove the base cover on the T440s to access the wireless card: http:// support. lenovo. com/en_ IN/detail. page?DocID= PD027945
