Where is the SMC on the logic board? Cleaning after spill.
Since the current problems I'm seeing SEEM to be related to the SMC, I want to pay special attention to that circuitry. Can someone point out where on the logic board that is?
I'm hoping a couple hours and a few dollars in cleaning supplies get it working again, but if not then I'll have to order a replacement board.
My Late 2013 13" Retina MBP had a mild coffee spill.
I turned it off immediately. Drained it as best I could. Opened the button. Then I didn't touch it for a couple of days.
Then I bought 4 pounds of silica gel dessicant crystals and put the MBP (wrapped in a towel) in a cooler with them. I left it there for 72 hours. The MBP was off for a total of a week.
I tried powering it on.
At first, everything seemed to go well. All the keyboard buttons worked. Trackpad worked. No issues. I plugged the charger in... It charged ok. It went from 19 to 28% while I used it.
Later in the day I came back to it and it wouldn't wake. I tried an SMC reset - no help. I came back a few hours later and tried to wake it and it came up. An hour or so later I shut it down just to see if it would come up. The power button did nothing. I tried a few combinations of attaching the charger, removing the charger, SMC resets. I got it to come on a few times but the boot up progress bar usually never made it past 50% before it shut down again. One time only did it make it to the login screen, but it shut down before I could log in.
Up until now the charger light would turn briefly green when attached and then go amber. But after this I got no indication from it.
I gave up and walked away. Twenty minutes later the MBP powered up spontaneously and shut down a few seconds after. This happened 4-5 times in an hour.
I walked back over to it and tried to power it on manually. It chimed and I saw the boot screen. The fan was loud and at 100%. It shut down before reaching the login screen.
I took the bottom cover off again and disconnected the battery. I haven't gone back to it in 2 days.
I did notice what appeared to be some light mineral deposits or corrosion on the DC in board.
I haven't had the logic board out yet to look at the other side. That's my next course of action.
I will clean it off with some 99.9% isopropyl and distilled water.
Is this a good question?
