@himanshu59930 start by measuring the AC adapters output voltage. If that is correct, replace the Battery on your laptop. If nothing else it will give you a known-well starting point for further troubleshooting. After that, you will have to start disassembling your laptop and checking the DC in jack and the charging circuit on your computer. You will need to find the schematic and component layout for your specific motherboard
