1. If the Macbook turns off straight away when the charger is unplugged, will most likely be the battery.
 
2. If you unplug the charger and the screen goes off (but the sleep light or fan still spins for a bit before turning off, showing it is running from the battery) it will be either the SDA or SCL resistors, which allow the battery to communicate with the SMC.
 
Would recommend getting a battery if it is the first situation. If it is the 2nd, try a new battery anyway before looking into the logic board. Visually check the board for liquid damage or burnt components too, especially around the 28 pin IC to the right of the RAM and above the battery connector.
 
EDIT: SDA and SCL resistor location
