Macbook A1932 had completely dead keyboard. I found liquid damage on circuitry on keyboard itself, and repaired it by replacing what i think was a 10k 0201 resistor (here's my post requesting schematic for keyboard circuitry where I included a photo of the resistor: [url]https://www.badcaps.net/forum/troubleshooting-hardware-devices-and-electronics-theory/troubleshooting-laptops-tablets-and-mobile-devices/schematic-requests-only/3240766-macbook-air-a1932-keyboard-schematic-820-01294-a[/url])

I found two capacitors on the board and one of the leads on one capacitor had bad soldering joint and the other joint connections not much better and there were several soldering joints that way to much flux around the joint redid several of them
The capacitors were a non brand that I did not recognize they got replaced and now it does not oscillating between relay but what concerns me a little bit is when the voltage is a little bit low the output voltage is around 130 volts and then drops down to 115 volts this happens around 105 to 108 volts if remember correctly
Now...Yesterday, 10:57 AM -

Hearty greetings to everyone, trust you all are doing excellently well.
Please, I have the above problem, the laptop turned on after the switch was activated but it will turns off in less than 2 seconds.
The power stables in very rare case. Once it was stabled, everything works fine.
Once the power switched is pressed, 5V and 3V were present.
The things i have done:
1. I have check for shorts on the board, but nothing. The board is short free
2. Not a power switch problem, it behaves the same without the switch ...Today, 05:05 AM -
