820-3332 board. Mother just shipped to me to look at. She had still some water near the machine and obviously got inside... She did not send to me first and took it to an computer repair shop. I can not find any liquid or signs/evidence or clues of where liquid could/would have been. The only...

I have a 2014 13" Air. (actually is being sent to me) It runs and displays fine to an external monitor. My sister said she shined her phone led into the back of the apple logo and doesn't see anything (while it is displaying on the external.) There is no backlight and what seems to be, no image...

Had some very minor liquid exposure/damage. There was some corrosion around the trackpad cable and J5700. This was cleaned up and cable was replaced with a known working cable. Passes EFI HW tests. Only issue I can find is that it will not go to sleep with the lid closing, otherwise it works...

I have a 13" MacBook pro (Early 2011) neither USB ports are "working". Each will light up a mouse for a split second and then goes dark. Both have the 5V. J4600 which also acts like a SMC debug port has SEL 10 HI (3.4v) and of course OE is low since it is GND. This should select USB...

I have an early 2011 17" MacBook pro. When I plug a legit (brand new as of a week ago) 85 watt charger in, light turns green, fans start spinning, can hear the DVD drive initialize, but then powers off and tries to power on again and then kicks off. Green light stays on charger. I figured it...

I have a Late 2011 13" MacBook Pro. No liquid damage seen. No obvious physical damage, alluding to dropping. Most of the time it boots just fine, runs OS just fine. I've tried different ram and swapping ram slots. Ran ASD and everything passes until it gets to memory test. Almost all of them...

4SNS/1/C0000008:TC0C -- 124 Error kicked out from AHT. Turns on, chimes, after about 5 secs the fan starts going full speed. Anyone know which "sensor" that is not working or which area of the board that is referencing? I looked in the hardware profile, under power and it says charger...

2014 13" retina. Sees battery. Says not charging. Has the lightening icon on the tool bar. Shows cycles (66) and total capacity of battery. Says 0 capacity left. "Battery Not Charging" and says "Replace Battery Now" is this a battery issue? Or could this possibly be a board repair? I've never...

I have a 2012 11" MacBook Air board that is giving the fan spin, no chime, 1 beep every 5 seconds goodness. What would you recommend I check or do? Is that a matter of the machine not seeing the ram? Or a bad ram module? It had some liquid contact, but not a lot and I do not believe any seemed...

I'm looking to buy this MacBook air, It's a 2013 13"... Is this "distortion" possible without a cracked or damaged LCD? Seller said it showed up that way after liquid damage and wasn't cracked... Anyone run into this situation or it was cracked and the seller didn't realize it...
