MacBook Pro 2020 (A2289) battery replacement issues.
I have just replaced the battery for the MacBook Pro 2020 (A2289). The laptop will only now switch on with the battery charger connected. The computer does not recognise the battery on coconut battery and the battery icon has an X inside it. System settings state that the battery is fully charged at 100%. When I remove the charger cable the computer turns off. I have ordered a replacement data flex cable incase that is the issue. Is it likely that this is the issue ?
