This is the way it works for the original Xoom too. I've seen mention of a charging light mod floating around the forums somewhere which enables the light even while the device is on. I'm pretty sure you'll be required to be running a custom rom to use the mod, but I haven't looked into it.Gents,
1. The charging LED does not light. Apparently it only lights when the unit is powered off. Ok, I can accept that.
I thought I wouldn't like no charge light while the unit is powered up but after some use feel the light could be distracting if you are using the tablet while charging.
It would still be pretty nice to see this mod integrated into CM9 somewhere
