Can you try re-typing that, using punctuation?

I think you're saying the charging light is green, but it's not actually charging. If that's the case, check the end of the AC adapter, and make sure the pin in the middle of the barrel isn't broken (If it doesn't come to a point, it's broken). This happened with my G4 iBook. It would look like it was charging from the barrel's light, but the computer would show no AC power being delivered.

If the battery being present causes the adapter to go red, it sounds like a dead battery. If it's an orange color, that means the battery is charging, and it will turn green when it's done. If it isn't turning green at all, the battery is dead.
