MacBook Pro A2289 No Power
hi guys I have a 2020 MacBook Pro A2289 it has the i5 CPU and is now acting as if its dead,
when I plug in the charger cable with a volt meter thing connected as well its drawing 20.3v and 1.11A
if I press the power button nothing happens.
but if I hold the power button for 7 seconds or more the voltmeter drops all the amps down to 0.00A but voltage stays the same.
any ideas where I can check ??
from what I can gather it must be charging the battery at 1.11A as nothing happens when the power button is pressed. I can successfully... -
I can confirm there is no short with the PU501 removed from the mainboard.
would you say replacing it should solve the issue ?...Leave a comment:
