@henaxl you are not telling us if it gives you any sign of life or any indication if it gets power.
To verify a symptom, follow the steps below:
1. Turn off the computer.
2. Remove the battery pack.
3. Connect the AC adapter.
4. Make sure that power is supplied when you turn on the computer.
5. Turn off the computer.
6. Disconnect the AC adapter and install the charged battery pack.
7. Make sure that the battery pack supplies power when you turn on the computer.
After that follow the checklist page 21 in the Hardware Maintenance Manual which you can download from here
