@kiehlashleigh this could be a bad AC adapter, a bad connector, a bad battery or a board level failure. 'd start with measuring the output of the charger and see if that is supplying the right voltage. If so, I'd check the DC-in connector to make sure it is still properly connected etc,. If you can give us the exact model number of your computer, I am sure we can find more information that might be helpful to resolve your issues.

@kiehlashleigh you can download the service manual for your computer [http://topics-cdn.dell.com/pdf/inspiron-15-3567-laptop_service-manual_en-us.pdf|from here.] It will help you with getting to the DC in port etc.
