Board is clean, no signs of liquid damage, PP3V42 is present PPBUS_G3H was at 4V, no green light on charger R7121, R7122 both blown I've replaced both resistors and U7100 Now PPBUS_G3H is 12.6V as normal but I still don't have a light on the charger and board won't start. Board seems to start...

Hi! I've got a 00165 board which got liquid damaged. I've attached screenshots of the main places I found corrosion Thing is, after cleaning up the corrosion in these areas and putting the board through ultrasonic, it power up just fine but will crash when loading macOS, showing a black screen...

So, I have this 820-3332 machine I bought from eBay because I'm an idiot. As soon as I got it I could see melted plastic and ripped up screwposts near the gpu. However the seller seems like a nice guy and said the laptop was like that when he bought it, but it's been working until recently. He...

Got a 820-3115 board here with no display. It has the usual dirt and some surface corrosion for a board this age, but nothing too serious. It will chime and I get usb activity, the screen gets energized(goes to deep black when booting) but never show a picture. Tried with a spare screen so it's...

Hi! I need a 820-3332 donor board urgently, so don't have time to wait from Aliexpress. Want to buy from someone in the UK that can ship quickly. Board must hame U8900 area intact and Q8930 Thank you

Got my first Macbook Pro 16" to fix, customer spilled wine on it. Damage in a few areas, mainly: J4900 burned, I removed it for now to clean the board. some corrosion on small components nearby Slight corrosion on C9080, removed it too Some liquid near U7650 but no visible corrosion Some liquid...

got this laptop in from a customer. Small signs of liquid damage near usb ports, especially on C2975 and C2978. I don't usually work on the newer models so just wanted some advice before I dive in. I get 20V on both usb ports but 0.01-0.03A so not turning on I cleaned the corrosion with alcohol...

so, I have an 820-2850 board that's acting weird. If I plug in the charger, the board will power cycle somewhere between 5-20 times roughly (pulsing the s0 rails) until it will boot further (I can tell because the optical drive will make a noise). Sometimes I get picture when this happens and...

So, I know this is an old machine but this customer has been good to me and I wanna be nice When plugging in my 85W magsafe I get green light but the board doesn't come on automatically like on other models. However, if I short the pads at R5015, it will power on, fan spins and the computer...

So I have an 820-3115 board. No obvious liquid spill but some green probe points from humidity Will always power from battery, however if using charger only behaviour is random Sometimes no green light, sometimes green light but no boot, sometimes it'll boot like normal Once on it will stay on...

Alright, this one kept me up all night. Have an 820-00165 that came in with corrosion in a few places, namely around U7600 and R1673 area. Was missing S0_CPU originally, replaced a resistor for S0 cpu power (can't remember which one, sorry) and that fixed it, managed to boot into os and...

820-4924 with unknown history Some general nastiness, signs of liquid around the LCD connector but overall nothing terrible Powers on fine but when booting macOS will freeze with the loading bar around 75%. Sometimes (rarely) it will boot fully in which case it seems to work fine. Have tried...

Hi everyone. Somewhat stumped on an a1466 with the 820-3437 board. Laptop came in with some general signs of liquid damage, I reflowed some of the worse looking areas with flux to clean them, then ran board through the ultrasonic. Now the laptop powers on fine with my power supply, but on...

Hi! Have done quite a few A1466 so far but this one is being a pain Got an 820-00165 off ebay, board looks good, no repair attempts, minor corrosion around SMC and U1900, which I cleaned up Didn't have S4/S5_SLP_L due to missing S5_PWRGD/DSW_PWRGD, reballed SMC, now I have PWRGD signals When I...
