Hi all, I have a 00928 board on my bench. It came in with 5v 0.21a, PPBUS was 0.5v. Found that C6913 was getting molten hot so replaced it and now the machine gets to 20v and comes on, but it only gets to a "charge battery" screen for a few seconds and then shuts off. This happens with both...

Hey all, having issues with a stubborn 00840 board. Came in for liquid damage and a new screen, repaired the liquid damage and the board is working great except for the webcam. In system report it doesn't show up at all, tested with a known good display assembly. ALS does work however. I checked...

Hi all, having an issue with a keyboard on an A2179. Had 2 come in for topcase replacement, one also needed a trackpad due to liquid damage and the other we re-used the existing trackpad. On the one with the re-used trackpad, everything went fine. On the one with the new trackpad, the keyboard...

I have an 820-01521 on the bench with a PPBUS_G3H short, 5v 0.01a on the charger. Getting 30 ohms on PPBUS, checked L7410, L7430, and L7210 and they aren't the exact same value but all are between 8-20 ohms, on a working board I'm getting 70 ohms. Does this mean the CPU is likely toast?

Hi all, have a 00165 on the bench that's being stubborn. Has green/amber light but no fan spin, 20mA from the power supply. Originally had some corrosion around U8130 and J6100 and the DC board and flex were destroyed, replaced the board and flex and cleaned the corrosion, got green light back...

Hey all, have a 00840 on the bench right now that's not booting and has no caps lock/USB activity. Was liquid damaged around U3770, cleaned up with heat and flux. Has proper PPBUS, PP3V3_G3H, and ALL_SYS_PWRGD. PLT_RESET_L goes high, L7210 stays at 0.98V and doesn't budge. Checked R1320-25, all...

What are y'all using for microscope cameras? Just picked up a new scope and I'm looking for one that won't break the bank but still has decent image quality. On my short list so far is this Mechanic one. Any other ideas? https://www.aliexpress.com/item/1005001864091613.html

I had an A1706 come in for a keyboard replacement due to a bunch of keys breaking off, I've heard the horror stories of trying to replace the keyboard itself so I ordered a topcase from MobileSentrix that came complete with battery, keyboard, trackpad, and touchbar. Upon swapping everything...

I have an A1465 on my bench with a really weird issue. It came in because the customer tried to update to Big Sur and the update failed and split his OS partition into 3. I backed up the data and wiped/tried to install Monterey from a freshly downloaded App Store copy on a USB drive and it fails...

Hi all, I have an 820-01598 that came in no power, 5v 0.01a. Missing PP3V3_G3H_RTC and the area around U6903 and the chip itself are gross. Only problem is, I don't have a donor and Mouser + DigiKey are both out of stock. Suppose I could order from Aliexpress but the closer the better. Any other...

Hi all, I have an 820-00165 that came in with it's BIOS chip wiped off the map. Got a new one from a donor board and I've tried downloading the files with clean ME available on the forum and editing the SN/fixing checksum, and while I followed through Piernov's videos and managed to flash/verify...

Hi all, I have an 820-3115 that is having issues. Came in with no liquid damage, customer reported they were watching a movie and it shut off unexpectedly. I get intermittent green light but it only pulls 0.013A from the bench PSU. Found that PP5V_S3 was shorted to ground (0.30ohm) and injected...

Hi all, I have an 820-00850 on the bench that's stuck at 4.9V 0.33A on the charger. PPBUS_G3H is shorted to ground on the system side (meter beeps in continuity mode, 0.109 in diode mode on system side with F7000 removed). Measured resistance of all the coils around the CPU and got nothing under...

Hi all, I have an 820-01041 on my bench that's bootlooping. Tried without the trackpad connected, same issue. It will sit on the boot options screen forever without freezing or rebooting but if I select the internal drive's OS or an external drive with an OS it will show the Apple logo then...

Hey all, have a 820-00850 board on my desk right now that came in with liquid damage, was stuck at 5v. Replaced a liquid damaged CD3215 and a few surrounding components and now board turns on and boots. When it gets to the OS the mouse is very laggy and the fans spike up to 100%. AHT reports no...

I have an 820-00138 on the bench that isn't charging the battery, but runs fine from the battery. No liquid damage, was dropped on its side and hasn't charged since then. Tried a known working DC board but same result. I tested with an el cheapo charger and it does charge, just not with my bench...

Hey all, had an 820-00840 come in liquid damaged. Cleaned some corrosion away from the area surrounding the CD3215's and after that the board was working fine for a day. The next morning, went to go turn it on and it booted half way then the screen went black. Took the board back out of the case...

I've got an 820-01041-07 on the bench that pulls 4.89v 35mA. Board is immaculate, no liquid anywhere and all indicators are still white. PPBUS is 3.74v, checked for CHGR_EN_MVR and it is missing. Is there anything else to check before suspecting the ISL9240?

Hi all, I have an 820-3662 that came in with the notorious crashing issue, swapped out the CPU MOSFETs with good quality FDMF6708's from Mouser and 5mins after the repair tested the board - it powered on w/green light and reached 700-900mA so that part was successful. This was using genuine 85w...

Hey all, curious if anyone knows where I can find a small clamp for doing things like SMC reballing. I've seen mention before of a store called Precision Rework, but I can't seem to track down anything under that name (perhaps they've since gone out of business), and I've tried 2 cheap ones off...
