Shorted C5701. Board works now. PP3V8_AON diode is still at 0.180. Weird. Should be at 0.360.

Or maybe it's in some sort of switched state and the short is normal?

Thanks. I found a dead short on P3V8AON_PVCC. Need to figure out what's causing that.

any thoughts? any ideas besides injecting current.

Any other way to go about this? I'm not board repair anymore, so I'm trying to avoid investing in equipment for just one computer. Are there any likely culprits with this type of thing, maybe based on the location of the spill also?

Any thoughts on how I might find this short? I don't think injecting voltage is going to help being that it's not much of a short.

Hi, yes, it's supposed to be around .360. I'm trying to find the source of the short but can't figure it out.

This had liquid-damage. After cleaning it, it worked fine but the front left USB was stuck at 5V. The computer worked fine for about a year and now all the USB ports are stuck at 5V. I'm posting pre-cleaning pictures. Any thoughts? PP3V8_AON is at 0V PP3V8_AON diode is at 0.180 PPBUS_AON is...

Thanks, it's not a hole so I'll have to figure out some way to run wire. The problem, as always, is how delicate the connection points are. Any movement of the wire on a 201 resistor will pull it off.

Does anyone have any tricks for accessing and soldering to a via where the pad is gone and you're only left with the microscopic dot of a line going to the other side of the board? Running a wire to the other is not an option for this repair because of the positioning of the damage.

Any other thoughts on this?

Yes, it stays on. Pressing the power button has no effect no matter how long I hold it. It doesn't turn it on or off. No change when using pads. Continuity is good between all the points. SMC_OFF_L is measuring about .715 in diode mode so that's normal also.

Yes, everything works normally but the power button has no effect, it doesn't turn it on or off, even though it's pulling SMC_ONOFF_L low.

This board had a spill around the power button. I cleaned it up and all the pins on the power button connector are functional and reading correct diode numbers compared to a good board. Touch ID works fine. The power button is pulling SMC_ONOFF_L low and I'm measuring that all the way over to...
