MacBook no longer starts after replacing the battery
crwdns2934249:0crwdne2934249:0:
I bought the replacement pack and immediately realised that the glue remover was missing. But that's not the issue now. After I removed the old battery and installed the new battery, I let the MacBook charge overnight. This morning I realised that the MacBook would no longer start up. When I disconnect the battery, the MacBook can start up, but as soon as I reconnect the battery, it won't start up. Do you have any ideas what could help? === Update (01/23/25) === Is it possible that the new battery is deeply discharged? I measured the voltage on the old, removed battery and on the new, installed battery, see the results for yourself. Old battery: [video|6519] - - New battery: [video|6520] + + + + + + + + + + + + ***UPDATE*** + + [image|3535503] + + After I reinstalled the old battery, the MacBook behaves as desired. It boots up and the battery charges, as you can see in the picture. + + The new battery must have a defect.
