DC voltages for 820-2565-A for MacBook Pro A1278 MC374LL A?
Would like to know what the voltages should read on the 820-2565-A MagSafe board to test in circuit?
Is 17.98 volts and 3.5 volts the correct input voltages for the board from the power supply?
Also the battery pin outs and what the correct voltages would read?
I get 11.75 volts and 3.5 volts at the battery socket.??
I have a steady green light at power supply and two green lights when test or press the battery level button. If I remove the power supply the battery level indicates two lights.
Reconnecting the power supply the battery level shows two green steady and the third flashing and then fade out.
MBP will not power on but seems to have input and battery voltages.
Thanks in advance for any input.
Is this a good question?
