Help with a macbook A1398, it does not turn on and does not charge, green LED and changes to orange, it only turns on counting 8 seconds and connecting the charger, but when you disconnect the charger it turns off, it does not show an icon or percentage of charge, it does not show a charging cycle the battery, I am repairing it, I measured all the voltages and they are all present except PP5V_S0 and P5V3V3_S4_EN, only those 2 voltages are not present, I have tried to repair but I have not been able to, I do not have voltages on the fans. Please who can help me.

When you press the power button on the front panel of your desktop board and nothing happens, one of the things you should check is the RTC oscillator circuit. If this circuit is not working properly the chipset won’t de-assert SLP_S3# signal and the computer won’t turn on. One easy way to check this is to press the front panel power button and then touch the 32.768 khz crystal pins with one finger. The electrostatic on your finger will induce clock pulses on the Pierce oscillator inside the chipset and the board will turn on. Be careful of not having too much electrostatic build up on your fingers; you could also a multi-meter on the ohm scale instead of your finger. If this trick works on your dead board, it means the RTC clock circuit is faulty. You could try replace the crystal, the 10Mohms resistors, or use an external 32.768 khz clock oscillator IC. Hope it helps someone.

I have a levono g40-80, which does not turn on, shows that the power led and battery are working, but the equipment itself does nothing, I have a laboratory source and the source tells me in the amperage that it is consuming 0.012 A without the battery, with battery are 1.038A and the 20v are maintained, estor a little blind since I do not have the schematic, if anyone is so kind to help me i would appreciate it very much.
