I noticed that some people are having problems with the CR48 charging light. As I mentioned in my unboxing post, we had a similar issue while charging my wife’s Chrome netbook. After charging it for 6+ hours there was still no promised white glowing light, indicating a full charge.
The solution: we found some advice online that recommended we remove the battery completely and then re-attach it. After doing that, and plugging the charger back in, the white indicator light showed up immediately. We booted up her notebook and the Chrome OS started up right away showing a full charge in the notification bar on the top right.
