Welcome to the Community Forums.
You can follow the guideline for checking operational charging and checking the battery pack as described here on the hardware manual (page 21-22).
Try to plug in the charger and notice the battery indicator LED.
Battery indicator should change from blinking amber to white after 1-2 hours with the charger connected and laptop not turned on.
Replacement battery may be needed on such cases. You can try placing the battery out of the machine in room temperature and try the same charging attempt.
Hope this helps isolate the problem for your machine.
