OK, check the connection IN the laptop make sure they are actually making contact and are actually working. Now IF that is all in order, then I suspect, that your Battery Charger/Internal Power Supply, has faulted, the External and Internal supplies are separate, with exception for tap off to battery charger.
I have had this many times in my shop, you can most likely buy the Power supply sub board assembly and replace it.
Below is a service manual that will show you what to do and the part numbers. Most likely Ebay will be your best bet, or go straight to Compaq or Compaq dealer for the spare parts, or use the 'net.
