    820-3330 fan turn but nothing more

    No CPU Vcore is bad :( Check U7400 area for corrosion. Any history on this board?

    820-2850 ppbus_g3h

    Issue around the TPS51125 possibly. If S5 power good is not coming on PPBUS will start to cycle.

    820-3476 Dead CPU - Swap?

    If the CPU has warped you heated it uneven and now it is junk. You can put any CPU from an identical board on there but the BIOS will need the ME fixed. CPU replacement is possible but it is just too much risk if you ask me.

    820-4924 wont power on while unplugged

    Run diagnostics and check for corroded resistors/traces around the SMC.

    820-2936 no touchpad/keyboard/usb on battery

    Where was the liquid damage? Possible 5V issue so was there crap around TPS51125?

    820-2997 thunderbolt display

    No schematics available. Just hack in an old charger brick inside the display or something.

    3787 Intermittent Black

    I'm looking for compatible chips. 6808 was only used by Apple so finding these new will be hopeless. I'm pretty sure FDMF6708N is a good replacement, anyone want to try? If you are in US you can get them quick from Mouser, I have them on order from China.

    mac book air with green light and amber light after but wont turn on

    So does the machine turn on if you just leave the flat cable to the IO board disconnected?

    00165 pm_slp_s4_l = 1v

    Any pulling on S4/S0 rails? Checked all rails for shorts? These CPUs do have a tendency to short...

    820-4924-A Missing PPBUS_G3H

    No warranties. Just get another battery. A1582 batteries are still of decent quality for the time being. But real new ones don't exist of course only reset pulled shit from China.

    820-2838 greenlight, but no fanspin

    3V3_S5 even present? PPBUS voltage?

    A1425 not recognizing battery after battery repair

    All these batteries from China are pulled used garbage so a bad battery is likely. PPBUS voltage can also tell us more.

    820-2838 not booting/no chime

    Does not sound good. I doubt this antique is worth putting time into. Bad MCP is very likely indeed.

    Retina 15" Late 2013 820-3787-A Green/Orange Light on Magsafe no fan

    Replace U9300 and Q9330/31 and pray the GPU wasn't killed by the 12V it got.

    820-3437 Booting and chime, logo crash (but still running)

    Could be anything. All depends on where the corrosion was.

    Replacement topdeck/keyboard for Retina 12" A1534 - preferred supplier?

    The sleep sensor(s) are on the side of the keyboard. So could be corrosion under them or in the connector. 2015 keyboard is different to 2016. The 2016 has 2 sleep sensors.

    820-3332: No power, MagSafe light turns green and off, then repeats

    Was this board messed with? Fans that do on/off is not a good sign :(

    820-2914-A , missing ppivs0_s5.

    Hopeless for sure. Bad CPU or bad traces in the board around the GPU. I bet this is an Apple refurb board with no serial number on the RAM slot.

    A1534 820-00045 Frankenstein

    Put in known good chassis and see if you can do a PRAM reset and do a reinstall of OSX. Corrupted OSX can make it turn off during boot.

    820-00281 Touch Bar pulsing power lines

    Could be pretty much anything. Corrupt BIOS, knocked off component, this one is going to suck! Ask for history
