Do You mean to ask if you can use the Laptops LCD to play your XBox on? When it is plugged into the USB to charge?
I guess not..... unless your Laptop has a VGA or HDMI input
(Which I doubt)
What you could do is use a Tuner card in the PCMCIA and connect the Xbox to that and fine tune it or AV the connections and yes, then you'll be able to use your XBox on the laptop....
