cable failure could be easily diagnosed with SMART. check for CRC errors, this counter shows controller <--> HDD data line errors. if smart is ok, next step is to change it to SSD. it could be simply the customer's behavior - i hade one with a habit of tapping rhythms on the palmrest. :rolleyes...

this is not "across cap" resistance, this is net resistance of all components between your probes. the only right way to test capacitor is to desolder it. the only stuff besides voltages you can really test with MM in circuit are low resistors or fuses. caps could be tested with an oscilloscope...

the reason you're reading low resistance on CPU core voltage is that it has CPU installed. CPU is basically your short unless its dead. CPU/GPU has very low resistance between power rail and ground, this is absolutely normal. just play a little bit with the numbers: CPU eats, say, 20W. now...

btw has anyone tried to reprogram DS2413? since there's no encryption and serial number could be simply copied from the known-good brick, it could be really helpful link parser sucks :( https://datasheets.maximintegrated.com/en/ds/DS2413.pdf

I am sorry if i'm not the first one to ask this kind of childish question. is there some kind of dictionary for things like for example, wtf is FINSTACKSNS_ALERT_L? maybe i have too much free time if i ask myself, what does PP stands for? Power Point? Power Panda? or SMC_BC_OK, what does BC...

NOSTUFF means that there's actually nothing here. you just short this pad with tweezers and it is equal to power button on the keyboard. don't be mad but i suggest you to watch 10-100 Louis's videos with corresponding boardview and pdf opened and try to follow his trace. i'm telling you that...

have you tried with other IO board? i had similar problem with older 2011 model.

i hope we're not buying bitcoin during a spike :rolleyes:

well, from my PC laptop experience i know that unreadable/corrupt bios may be the cause for dead Vcore/permanent S5 or even no charging light on some Compal platforms. first thing i did with this board is i tested all rails and mosfets for shorts. this board has zero hints. so is that possible...

No Title this is NOSTUFF resistor, it is also easy to find since this pad is pretty big and present on both sides of the board.

btw, is there a better solution than a 47k resistor?

vibration + sandpaper-like aluminum case + pressure from HDD + 40-50°С = short circuit, slowly burns dataline or +5v. i repaired 4 devices with this issue a few years ago, no one returned. you either install SSD or put insulation tape under the cable, that's it. there are thousands of different...

small update. battery change made no progress. charging works as normal (forget this "green light" thing, it was simply full, shame to me) just after SMC "deep" reset, it's kind of starts with full fan and 0 on P1V05S0 and PPVCC_S0_CPU. can someone share 100% working "clear me" bios for...

did you reset NVRAM?

the reason everyone using it "once in a year" is that there's some apple warranty stuck to 2016 and 2017 models. wait a year or two and you will see how people look at you when you say something like "of course, Sir/Mam, i will transfer your data to this refurbished macbook and you may take it...

how long is that "quickly"? Could be bad Q7560 (you should also check if both gates are ok, sorry, you need an oscilloscope for that), check R7516, R7546, C7588 also, if you're checking voltages with an oscilloscope, you're seeing "wobbly" voltage almost everywere

so it looks like this model has some weird relationships with the battery - i have found several posts on Russian forums, people claim that it does not autostart with no battery attached. This also means that if the battery died (overdischarged, for example), we will have this strange behavior...

call me dumb but did you try to test it with windows/linux/"native" os version (internet recovery with command+R installs "factory" version instead of latest)? at least, Microsoft is well known for breaking ACPI support for old devices. From my PC experience, wakeup problems often come from...

well, genuine 19V with "60-watt" chip :) of course, i have a genuine brick too, but i don´t believe it could get S5_PGOOD if something was wrong in this area.

Hello everyone Charger light works normal without battery. With battery attached it stays green. SMC Reset changes light like it supposed to. Energy consumption: 0.04 amps S5 rail present, SMC_BC_ACOK high S5_PWRGD High PP3V3_SUS present s4 rail is as dead as Steve Jobs. i do not really...
