Troubleshoot Lenovo thinkpad does not charge with new battey and charger

[Mohan Rajan]

I am only able to use the laptop when connected to mains power and not on battery.

Have you try to uninstall the Battery driver on Device Manager? Try it and make a restart then test if works.

Lenovo doesn't play well with some 3rd party batteries. Try what jamescv7 said and see if that works, if not try another brand or if you are brave, you can try this (Not Recommended) : Unlocking Thinkpad Batteries

Remove the battery and the AC adapter (charger). Press and hold the power button for 3 - 4 seconds with these removed. Pop your battery back in, along with the AC adapter.

If it still refuses to charge, you could be looking at a bad battery or possibly a bad charging circuit on the motherboard.
