I'm guessing you found this site:
http
/www.ecs.com.tw/ECSWebSite/Product/Product_Detail.aspx?CategoryID=3&DetailID=405&DetailName=Feature&MenuID=93&LanID=0
The search showed it as ECS G553
However there was a listing on the UK eBay site for a PowerNet GREEN553 Centrino Laptop (http

I have also seen it as a Alphatop Green 553
My best guess is that the one you are referring to is an ECS G553. I couldn't find a picture of the back of the LCD screen to see whether or not it has "Excel" on it.
