Heyy there, this mac has no keyboard backlight. I'm not sure what changed because originally when i got the board working, half of the KB Backlight worked. Previous tech had ripped left side KB BL cable off completely but right side worked. I ordered top case and neither works. I tried putting...

This turned out to be a screen issue. Test screen regularly came on. I attempted to transfer donor t-conn but must have slight damage to ribbon cable now. gets intermittent distortion and I cant see where the damage. resoldered and exact same symptoms :(. WIll have to order a new screen

I was able to reload it with Ventura but the internal screen stops working and now external works fine. I literally have to wait a whole day for internal screen to work again. It will stay working until the screen shuts off/sleeps or the mac is powered off. If it is the first boot for the day it...

I was able to get this working by changing out the CD3217 on left side again and some components around it. All seemed good and it boots, but after you turn it off, it wouldn't boot up again without letting it sit a long time (usually have to wait until the next day). It seems to be on as when I...

Not finding anything. With your battery suggestion, it does appear that u3100 port behaves differently when battery plugged in. It doesn't show any voltage on that port until battery is unplugged again then it goes back to resetting at 5V. The others flash 20V and reset with battery plugged in..

Turns out it was R5610 in my case to remove both port 1 side nands

This board had 6 nands but when trying to reball 2 of my donor Nands were damaged. From Iboff's video it appears I can still transfer the remaining 4 but I need to cutoff 3v3 for ocarina on the two FLP's to make them NFLP's. Would removing R5610 be the easiest way to cutoff the U9100/9200?

Hi there, had some shorts on the LDO's U3100 and U3200 Replaced both CD3215s and shorts gone and now all 4 ports are 5V and resetting. Missing LDO 1V1 on U3100, Checked resistors around it and diode check and everything looks good. Tried rom from different board and same behavior all ports act...

Here are some screenshots of crashes. Don't think they will help much. New battery from MS didn't change anything. It doesn't last any better than the one from IG either. I think some of these are from running out of power.

I got an error once during restore but a couple of times it just goes to the lock like its done so I assume it finished but no boot of course. Yes pulses at L7700 that's how I discovered. Board was liquid damage but not bad. worst areas were Q7065 and that seems to be working and U6500. I...

It does go to DFU so I tried DFU revive and restore. Board goes to 20V and draws up to about 100 mA but then back to 0. No shorts on the coils. I replaced U7400 as it was getting hot. That is no longer getting hot but Im guessing it's cpu issue if PM_SLP_SUS_L is unstable? Following the power up...

Yeah seems as though it doesn't work with Ventura/A1990 anyway. Well in regards to my case, I buried the MacBook for 20 plus hours and it hasn't frozen or crashed but it does still spin fans up if you force it off which gives me good reason to believe it still has issue. Any advice? I think the...

Yeah I had external unplugged. If I set to integrated only it would show the D, if I selected dynamic it would go back to i. Makes no sense

I was thinking it was related to having charger on ports on left side... I have yet to see it happen with battery only or with charger on right side as of recent anyway. Today I was able to get it to freeze twice by having charger in either left side port and external on right side simply...

It seems like sometimes more likely to crash while stressing dgpu but other times I can run video, valley software and external display until battery is dead. I think more likely to crash while charging than when just battery. Is there any reason you can think of that would make sense? Something...

This has new battery that is reading 7300 mah and normal but when the Mac is working and I’ve been able to hammer the gpu and such the battery only lasts a little over an hour. I believe it had this issue before I changed the battery though also. It sometimes restarts during boot or just...

SOLVED Thanks! L6703 was visibly distorted. Replaced and trackpad is working normally.

Ok. Different new battery and I tried some other old batteries and same behavior

Ok. I think we just installed a new battery but I can try another. Would wired mouse not lag but trackpad possibly due to battery? Is this because trackpad is more of power hog would it matter if plugged in lot charger or not?

No, pp3v3_g3h is shorted directly to ground
