Is PP5V_S5 5.01V or 0V? You specify it twice in your post S5_PWRGD high? PM_DSW_PWRGD high?

I've not been able to make it crash anymore, its been running a 480p video with 3% cpu load avg. for hours. But I've noticed that plugging in the charger to the AC while the magsafe is already in the laptop will make it crash though, but only if the probe is connected... I've moved the probes...

6miliOhms? You have a short to ground Look for anything that looks messed up and/or getting hot. You might need to inject voltage to see what gets hot though, not sure if U7000 will try to keep working when its output is shorted.

CHGR_ACIN voltage? Resistance to ground on PPBUS_G3H in Ohms (with the power disconnected of course)?

I think you can get the chips from aliexpress or eBay, no idea about the quality though as I never had to replace this chip before. Its densely packed with solder balls so make sure to align it properly If thunderbolt is no big requirement just go without it as its not worth spending time and...

Will do, I think the leakage of the transistor inside of most ICs will make a PGOOD signal float around ground level without pull-up as well. After crashing the system because of a voltage spike on PP3V3_S5 caused by a pulse from my desk light I have not been able to get it to crash...

PP3V3_S5 is looking alright as well. I think I saw the scope catch multiple falling edge triggers though. So I'm running it again at 20ms/div to see if I can catch those fluctuations. But I might have been wrong EDIT: The system seems to be very sensitive to my desk light? If I have it close to...

Can confirm that low load is more likely to let it crash. In my case I often make it stream some music from my local library and thats been pretty effective at making it crash. Stuff like YT also works alright Stress testing the device will not make it crash at all. Trick seems to be not to...

4μs/div by the way The wait is the worst, at this rate its going to take a couple of days...I already confirmed PP1V35_S3RS0_CPUDRR not being at fault and I'm currently testing PP3V3_S0. Are there any power lines you recommend taking a look at first? (On the picture the voltages you see on...

Let me know if it works for you. I'm currently keeping track of any power lines dropping just before ALL_SYS_PWRGD does before I solder anything I'm sceptical about it being a contact issue as the problem gets more frequent once it keeps crashing and you keep rebooting it. But I'm hoping :)...

No Title ALL_SYS_PWRGD drops before CPUVR_PGOOD drops. I guess at this point its just a matter of going through a whole bunch of power signals to hopefully see which one goes first? CPUVR_PGOOD would be much easier :(

Hey duke, Is there any information or speculation about this issue so far? I have some free time on my hands this week so I woudn't mind experimenting around, who knows what I might find. (I tried to DM you about this but it seems your "Quota" has been reached and it won't let me send) Thanks...

Bridging a fuse is a really bad idea, please don't connect PPBUS_G3H to PPBUS_S0_LCDBKLT without the fuse in between. (Especially if it keeps breaking!) The new fuse might have blown already as well. Check the fuse with diode mode, also what is the resistance of PPBUS_S0_LCDBKLT to ground?

If you really think its U2800, remove the shield and check its temperature directly at the chip. You can de-solder the shield by pulling it up with your tweezers while heating up the sides where its attached to the board with. I assume its very similar to removing shields on iPhone motherboards...

Only thing I can think about is that by doing that you're introducing a piece of metal to the ground traces that has a different potential so you will be creating a microscopic spike or drop in voltage on ground. Because you're holding the metal piece or by using a long wire you might also be...

Voltage of PPDDR_S3_REG? The chip is probably just dead or not properly soldered back on. The system will happily try to go into S0 without this voltage being there as its not being checked as existing (afaik) Unless you kept solder bridges on the board I do not think this can break the...

You can try to flash a clean rom onto the SPI though, that would be my last guess before I'd give up. Just to be sure since I don't think you confirmed this yet, but you did check the SPI termination resistors right?

Hey everyone, A Macbook 15" Late 2013 model here with no visible signs of water damage. The device suddenly powers off after using it for somewhere between 10 to 40 minutes. Having a high load running on it won't charge the issues (Furmark + Prime95 for 20 minutes would not cause the device to...

Alright so the light on the mouse tells us nothing, it will only tell the system is powering USB ports :(

I highly doubt this issue is being caused by the charger honestly. With charger that is meant for a smaller macbook it will just be slow and/or not charge. At best maybe if they used a really shitty Chinese charger, because anything can happen while using those
