When battery plugged in just beeps and won’t boot up.
My MacBook won’t turn on when battery and power is plugged in.
My MacBook turns on fine when the battery is disconnected and I use the sequence
Hold power button for 10 seconds
Connect power source
Carry on holding button for 10 seconds
let go and Mac powers up.
As soon as I disconnect the mains connect the battery in and then put the mains back on a beep with white light on the front happens every one second.
I’ve tried to hold power for 10 seconds then Connect at power hold power still including shift, control,option and command for 10 seconds and then let go but again Mac does not boot up and gives beep everyone one second.
Any ideas?
