hi @abhishek0
It may be that the battery is failing and the charger can't charge the battery and run the laptop at the same time.
Create a battery report to check the status of the battery.
When you have the report, compare the Design Capacity value versus the Full Charge Capacity value. For a good battery they should be the same. As the battery ages it deteriorates so the Full Charge capacity value will be less, maybe a lot less.
If it is determined that the battery is faulty, here's the hardware maintenance manual for the laptop.
Go to p.39 to view the procedure to remove/replace the battery.
On p.69 Item #15 you'll find the part number (FRU number) for the battery. Search online using the part number only to find suppliers that suit you best. The part number is also printed on the battery in the laptop if you wish to verify the number.
