Dear All,

I own two X61s: 7669-45U (with extendable WWAN antenna), and a 7666-WKD (no WWAN Antenna). Both machines have (I believe) standard displays -non Ultralight's.

1. Do you know WHICH X61s models come with Ultralight display & extendable WWAN antenna? Would you be able to give me some model numbers in the form 7xxx-xxx so I know what types of X61s I should be looking for?

2. Do you know if there are any X61s models that are WWAN but don't need the extendable Antenna (did Lenovo ever developed WWAN X61s that do not need the extendable antenna attached to the top lid)? Would you know again its model 7xxx-xxx?

Many thanks,
Christos
