MacBook doesn't work with the battery installed
I recently replaced a logic board in a Macbook Core 2 Duo using the iFixit guide.
The replacement went fine – no issues, but now the Macbook will only work when the battery is NOT installed in the machine. With the battery installed, the machine powers on, but then the screen immediately goes black, no start up chime and the light in front is on (not blinking).
On the replacement logic board I used, the PRAM battery was already connected. I know it might sound silly, but should I have unplugged that from the board and then plugged it back in? The machine is also loosing it’s time setting. I have done the PRAM reset and the SMC reset. I’m at a loss as to what to do now.
Any suggestion would be greatly appreciated.
