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...
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.
Hi, I'm selling my online broken MacBook purchasing website and am talking to people that might be interested. We've been on the first page of Google for most relevant results for the last 6 or 7 years. Online reviews are all positive. Contact me directly if you're interested. Let know the...
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...
We're down to one technician so there's no way we're going to get to 80% of the stuff we're buying. We're just filling up our shelves right now with purchased computers. Let me know if anyone's interested in a source for Pros or Airs or both from 2010-2012. (We're in the U.S.)
We bought all of...
I have a 2019 15" that goes through the online recovery and then shuts down at the same point every time. It will do the initial boot with countdown, then does a quick fan spin up and shuts down. It's as if I've done an SMC reset - very similar sound with the quick fan spinup. It did boot all...
I'm getting killed buying T2 computers. They're directly from customers, and about 90% are fine, but the other 10% are a complete pain and it's starting to add up. I understand that they're worried about their files not getting deleted, but they're assuring me beforehand that the computer has...
This board was pretty clean. After replacing a few components around UA900, it's booting normally but the power button is not working. Nothing happens when I hold it down. I tried another button. No change. Any ideas where to look for something like this? Everything around the power button is clean.
This board is fully functional but the fans spin up after a few seconds. I've tried it in an entirely different case and it does the same thing. I replaced Q5871 being that it was one of the few areas to be hit. No change. Online test shows no issues. I've attached pictures taken before...
Any thoughts on where to start with a backlight issue on this board that had a very minimal spill? I can't find any sign of the spill or any physical damage on the board. There is video but no backlight. Works on external monitor. Keyboard, trackpad, everything else works fine. I tested it with...
I have a semi-functional 820-00850 that is stuck on the Activation Screen. I attached a picture. I'm talking to the previous owner so they went into their iCloud account and set it to delete when it makes contact with the internet (see attached screenshot). It keeps coming back to the Activation...
I have a non-spill 820-4924 that has an SMC that won't come on. The board is clean. 3V42 is there. SMC_RESET_L is there. PPBUS is low at 12.25 being that the SMC is not on. I'm not getting SMC_ADAPTER_EN or SMC_PM_G2_EN. Not sure where to go next.
I have a non-spill 820-3476 board that's cycling quickly. S0 voltages are cycling extremely quickly, about twice a second. Not seeing anything on CPU voltage though. I can't find any shorts or anything heating up. Sometimes the Magsafe light won't come on when plugging it in. In those cases...
Any idea if this board would still be able to use the left USB ports if I just pulled UB000? It has a short on the 3V3_S0 line (PP3V3_TBT_T_S0) on this chip and I don't have any interest in replacing the chip. But I would be fine if it only had 2 USB ports vs 4.
I've heard of a possible bypass for the GPU on this model, something like the 820-2915 bypass? Does anyone know if this is possible? I've seen mention of a Facebook page but I can't access it and have tried with no luck to join the group.
I have an 820-4924 that restarts right when the boot progress bar starts. It wasn't liquid-damaged. My guess is some type of bios issue. I'm trying to fix it with my Medusa but when I try putting a new bios on it I don't get any USB drives at the boot menu. When I put the original bios back on...
This board had very minimal signs of liquid-damage near the USB-C ports. I attached a picture. It's not the best but you can see where the spill hit. This will turn on and work fine with an external monitor but if I attach the LCD it won't display anything on either screen. Any ideas or hope to...
This board keeps killing batteries. It had some very minor liquid-damage on the LCD connector. Nothing near U7100 or the SMC. Diode measurements on the SCL and SDA lines are good at .502 and .500. The battery will work for a while but then lose it's capacity and die. We're on the third one. As...
This came in with no spill, with a swollen battery and 5V on USB. I'm not finding any shorts. PP3V3_G3H is at 0V. No short. PM_EN_PP3V3_G3H is at 0V. Diode measurement is good at .580. Is this just a damaged U7000?
