Why is my display not turning on
I’m trying to repair and upgrade my brother’s water damaged MacBook from many years ago.
I just replaced the battery because it had gone thru to many cycles.
I tried to turn it on and I know it will take long to boot but I haven’t seen any upgrade take this long for booting.
I clicked power button and you could hear the fan and other systems along with that the screen was black along with Apple logo on back of the lid. It also making a beep every 7 or 8 minutes.
