I am afraid to say that the DC power jack of your laptop has gone bad. If the laptop's DC power jack is faulty then the power doesn't even reach the laptop's motherboard. As a result of which neither the battery charges nor the laptop powers on without the battery.Some power jacks(power receptacle) fail under normal operation of your computer. After a year or two of usage. After the jack is moved back and forth enough times ( when you insert the power adapter cord and then remove it many times, it comes loose).Generally a new DC power jack will cost around 2-6$.Do you have electronic equipment repair experience ?Do you have soldering knowledge ?There are usually four terminals of the DC jack connected to the motherboard.Check all the solder drops of all the four terminals for burnt marks.If you don't find anything wrong then also we will have to desolder all the four terminals and then re-solder all of them again.Before resoldering you also need to check whether the DC jack is working alright or not.For that remove the DC jack completely from the motherboard and then connect the charger cord to the DC power jack and then test the four terminals of the DC power jack using a multimeter to see whether current is flowing or not.If the current is not flowing then you will have to replace the DC power jack with a new one else resolder the old DC power jack.If you are you comfortable working with electronic components & circuitry and a soldering iron then you can try all the above process else the best bet will be to go to a local repair shop.Please let me know what you want to do.Sorry to give you a bad news.Regards
