My notebook gets shuts off immediately when charger is unplugged

How to rectify this problem?

What is the charge level of the battery? If it is too low, the PC will not be able to operate with the mains unplugged.

Also, here are some troubleshooting steps you can try:

If those confirm the battery is not charging or not holding a charge, you would need to replace it.
 
If those confirm the charger is not working, you would need to replace that.
 
If both the battery and charger check out OK, then it's an internal problem with the circuitry in the laptop,  and unless the laptop is still under warranty, it's likely to cost more to fix that than to replace the laptop, outright.
 
Good Luck
