Trying to track down the data sheet for 58879D CSD55879Q3D = U7600 Not finding a whole lot. Ordered this as the closest I could find from Digi key CSD87334Q3DT

Ok, back at it. Little fun fact. PP5V_S4 is at 13v ! PP5V_S4 to PPBUS_G3H 0.7 Ohms

Well, I guess I have spares of those...lol yes, U5920/30 missing.

Trying to trace SSD Nand power. Schematic shows U5910. I see soldered pads, but missing ? Doesn't look ripped off?

Yes, checked J9600 is closed. Appears clean and connected. unsure of internal video, board is out. Flashing folder on boot. Booted to disk utility, unable to see SSD. J8500 Pin 1 : 0.314 pin 3 : 0.315 This unit they are really looking for the data.

Must have goofed something up. I do have video. I have external video Via USB C. Still a flashing folder. Unit is running outside of chassis. Sorry, also a first responder. So time on this has been sporadic at best this week.

That was helpful, found short in cap C4205. Didn't take much at all. (Had to order) U8203 cooled down PP3V3_S4 Pin 6 3.36V now However now, no display? Gonna poke around, but good progress !

Gotcha, I'll report back !

Pin 6 - 0.000 in diode. Pin 6 to ground 0.5 Ohms

A1706 820-00239-A No LED External Only / No SSD No liquid damage found. No power a the nand. Boots to external screen only, then flashes folder. U8203 Gets really hot. PP3V3_S5 Pin 1 - 3.36V PP3V3_S5 Pin 4 - 3.37 PP3V3_S4 Pin 6 - 0.19V Best method to isolate PP3V3_S4 ?

Gocha, ordered. Thanks !

Does it require a battery ? Same issue on the bench without battery.

MacBook Air "Core i5" 1.6 13" (True Tone, 2019) 820-01521-A A1932 Over 150% CPU Kernel_task PID 0. Fan running what seems like full speed. Dam near unusable. Not booting on battery. Super slow. 5 Minutes to click anything. Removed board, no water damage found. Boots up currently, if...

Same issue here. Forum isn't as active as it use to be. If you do use A1 or S1 let me know how it works out for you.
