OK, does your laptop adapter have a light? If so, is it illuminated? Does the battery have lights and do any of them light up? Does the laptop show any indication of charging (usually a green battery light)?
So, if your adapter has a light, but it isn't illuminated, your adapter is having issues. If the adapter is lit, check the battery lights. If any are lit, it is charging the battery and both the battery and charger are OK. If the charging light is on on the laptop, but the battery shows no charge, then the battery and/or the motherboard is to blame.
So check those things, and tell me what you find.
