Oh, sorry! My bad! SMC_ONOFF_L is at 3.42V.

As i said in the description i have already replaced the keyboard. And have ordered a new trackpad and trackpad cable. will test whey they arrive and will post results. Still wonder how that trackpad might be damaged tho. Nothing broken bent or corroded under the microscope.

Have done that already, not with actual wires, with a pair of tweezers and it works normally.

It actually starts every time with no battery connected. I have ordered a new trackpad and trackpad cable. will post results when i test it.

Customer donated this A1466 to our store after he had spilled something on it. After some inspection, the machine had liquid damage on the lcd connector, the backlight fuse was burnt, and there was some liquid dmg on the keyboard as well. Replaced keyboard, backlight fuse, led drive, lcd...

ok thank you, i have ordered them, i will post back results when i have them. I need to force restart when it freezes and i have cleaned it, it had too much dust but not water damage anywhere.

Hello, the board is 820-00138-A, it freezes once after a day or two, the trackpad is till working but is stuck with rainbow wheel. I tried without the pci ssd with external hdd with usb and it still freezes. The diagnostic while holding d at the start does not show any errors. Any ideas? Could...

When i say it's shorted i mean that resistance to ground is 0?hm. Diode mode reading is 0.00v. I restored ppbus_g3h by replacing q7310-7311-7320-7321. As I said before this board has been messed with already. Using an original 60w magsafe 2 adapter i get a green light that turns amber as it...

Good Evening, Customer brought in a 820-4924 with a green light and nothing going on other than that. After some digging around i found out that it had no ppbus_g3h. Restored that and now the machine wont do anything else. Did some measuring around and i found that PPVCC_S0_CPU, is shorted. Is...

No its ok, thank you. Not looking for a monkey see monkey do kind of help. You already helped a lot just by pointing me to the right direction. Did some google search, was able to find many guides on how to clean the me region. I actually did it and the machine is now in perfect condition...

I did download the bios you had uploaded, and i think somebody else stated it before me but that file is not ok. The machine doesnt even chime with that bios. Anyone managed to get their hands on a clean me bios for these boards?

Hello, Got a 820-00165 that had a not powering up issue, after some measuring around and after a burnt isl replacement the machine would then not charge the battery. After replacing the smc now it powers up, chimes, i get an asd without errors but it wont boot on any media. I connect the hdd...

That was my problem as well, but after some close inspection on the board, i found out that L8608 was missing, i put one there from a donor board and the machine booted up and is working properly. So it wasnt a matter of lcd connector, or doing something wrong. The voltages were the ones i...

The strange thing is that pin 3 has 3.3v but L9000 has no voltage, c9002 nothing as well, traces from pin 2-3 to those are fine and they have continuity. I m getting the urge to send this in the garbage pile but this was brought on some sort of "warranty". Any ideas are welcome.

Update, i changed the lcd connector still the same issue. I even shorted the 2nd and 3d pins and the 2nd one still doesnt have 3.3v. I m running out of ideas.. Is there any way this is a gpu issue?

Pin 2 - 0v Pin 3 - 3.26v Pin 1 of C9002 - 0v Pin 2 of L9000 - 0v. Lcd connected.

Ok i got something, i got some flux on the lvds connector, did some cold joints, now i got 3.3v on pin 7. But still no image, pins 38-39-40 of j9000 got 0v. fuse seems fine , led drive on the other hand not so well, should just change all of that just in case? Would really love to get something...

I have done that already, its 100k?hm as its supposed to be according to the schematics.

Pin 6 - 0.52v Pin 7 - 0.51v Same measurements with lcd connected and disconnected.

L9010/9011 are fine, traces seem ok under the microscope, Pin 4 - 3.3v Pin 6 - 3.3v Pin 7 - 0.082v
