I replaced my keyboard a couple of weeks ago. After replacing it, the status of battery in the task bar said ‘replace soon’. It was fine before i replaced my keyboard. The macbook has been restarting after a while of it being on because of what i thought was a battery problem. But after unplugging the battery from the logic board and running it from the charger, it still restarts after a while. So this doesn’t seem to be a battery problem. My Macbook now won’t turn on at all, plugged in, with or without the battery connected. It happened after i tried an SMC reset. I’ve also tried a PRAM reset with no luck. Do you think this could be a logic board problem? Thank you for any help!
Your computer may actually be turning on without anything showing on the screen. Does the Caps Lock light come on? Does the touchpad make clicking sounds when you press it? If that’s the case, the computer is on but something is not allowing it to proceed far enough to light up the screen. Try connecting it to a different monitor through a Thunderbolt port to see what’s going on. If that doesn’t help, you may need to open it back up and see if all connectors are properly seated.
