Q: My macbook pro neither starting nor getting charged. Charging dim green light while putting it under charging

depending on your model laptop (because you didn't specify) you may be able to remove the battery.

If your model supports this remove the batter for 30 minutes and unplug the computer at that time

replace the battery and connect to wall outlet, not a power strip or batter backup and reset the SMC

Reset the System Management Controller (SMC) on your Mac - Apple Support

Take the Mac and the charger to an Apple Store for diagnosis.
