Let me just say that you can't go wrong if you unplug it. Now for older notebooks (before ~2006-2007), do unplug it. For newer notebooks, it doesn't really matter. However, just to be extra precautious, unplug it.
are you sure you have it fully charged? (also i heard that if you buy a new electronic and you unplug it before it is fully charged it will have less full battery usage every charge, so if you unpluged it just after it started charging the first time you might have almost no battery power at full charge)
An electrical cord is provided for just that purpose and when plugged into an electrical outlet, the battery charging light will come on. After the unit is fully charged, the Battery Fully Charged light comes on and you can unplug from electrical outlet and use anywhere you need it.

Yes, the battery is fully charged.
