I’m hoping someone can give their opinion on the symptoms I’m seeing before I spend any more time and put money into this. I got this MacBook from a customer and after looking at it they decided they didn’t want it.
It doesn’t turn on and there’s no visual signs of life. I have tried resetting the NVRAM, SMC, power cycling, unplugging the battery, using the charger with the battery unplugged. Removed the motherboard and tried cleaning it then putting back in but to no avail. The fan does spin for a second, then stops, then starts and repeats until the battery drains. The battery cells are flat. I have also used my dock and plugged it into my monitor but it doesn’t pick it up. I’ve plugged my keyboard in and it looks to be turning on and off, seems the MacBook must be in a restart loop. The trackpad also clicks.
Any ideas or suggestions are welcome. I suspect the logic board is knackered.
Thanks in advance.
