Spilled orange juice (with bits) on MBP with Touchbar. Some power & Touchbar problems...

    Hello everyone,

    I have a late 2016 15" MBP with Touchbar running macOS High Sierra version 10.13.4. I got it at the beginning of January 2018, so it's about 4 months old.

    Yesterday I happened to accidentally spill a glass of orange juice (with bits) on the desk where my Macbook was. At first I thought none of it actually touched my machine, but it seems some of it did. However, it appeared that none of it got into any of the ports (or anywhere else). The Macbook was working perfectly. No problems whatsoever. I had a sturdy case on it anyway, so this must have helped.

    About 1-2 hours later after the unfortunate incident, as I was surfing the web (Safari), I noticed the touchbar was completely blank/black, and none of the buttons that usually display on there were visible. I knew everything was just fine the last time I happened to notice it. I tried switching to Photoshop (as this usually brought different touchbar buttons up), but nothing happened. It was dead -- really.

    I restarted the machine once -- the problem persisted. Then shut it down and closed the lid, then opened it again -- the machine booted and the touchbar seemed to be working again. Then about 20 minutes later, it disappeared -- once again, completely randomly and unexpectedly. I tried shutting it down again, but this time it didn't work.

    After some careful research, I ended up taking several steps to help restore the touchbar to its good working order:

    1. Reset NVRAM -- this did absolutely nothing.
    2. Reinstalled macOS -- the touchbar worked for some time, then the same thing happened. It just went black.
    3. Reset SMC -- same as no. 2 above.
    4. Booted in Safe Mode -- same as no. 2 and 3.
    5. Run Apple Diagnostics -- no problems found.

    However, I noticed another problem alongside the disappearance of the touchbar. Whenever I closed the lid (which supposedly puts the Macbook to sleep) and then opened it again, the Macbook would restart. An error would show up saying that the machine restarted because of a problem. Here's the error report:

    FYI, after resetting the SMC and booting in Safe Mode, the touchbar would work until I closed the lid. When I opened it, boom -- it disappeared completely.

    Also, there were no settings available for it in the System Preferences, as if my Macbook didn't have a touchbar in the first place!

    Oh, and two of the ports seem not to be working properly. The Macbook won't charge when the charger is plugged into any of those two.

    Any suggestion? I've kind of exhausted all available options/fixes... It doesn't seem to be a hadware-related problem, though...

    Thanks & cheers!

    It is still under warranty so take it in. Could be completely unrelated to the spill.

    However, if they detect that the moisture sensor have been tripped they may declare this accidental damage and refuse to fix it, unless you previously bought AppleCare+.

    Yes --- That was also my though that the orange juice may not be related.

    This may be one of those times that you don't mention a liquid spill up front, particularly if you believe that nothing actually got inside. You really don't want accidental damage to be the focus of the discussion from the outset, unless it is obvious from the outside. Let the tech ask you first.
    You shouldn't be particularly surprised if they do find a tripped moisture sensor, but also good news if there really was nothing inside. You may have a legitimate failure, nicely covered under warranty.

    @jerryk & @DeltaMac

    Those were my thoughts exactly! All problems listed just didn't seem related to the orange juice, except the issue with the ports... The MBP is working perfectly, there's actually absolutely no difference in performance. None that I could notice, anyway. But it seemed too much of a coincidence that this should happen after spilling the orange juice...

    There was juice on the case, a little bit on the back cover, and absolutely none on the screen/keyboard/Touchbar (the lid was closed when it happened). So unless the juice got into any of the ports, I don't think it's the cause of what I'm experiencing... I mean, settings that suddenly disappear as if they were never there in the first place? Very odd.

    Is there anything I can do myself at this point? Like, to check for any water damage, etc?

    Thanks a bunch!

    The moisture detection is in the inside, so maybe if you peak in the back. Maybe. There are two common types. The first is a small dot or rectangle. It changes color when wet. The second looks like tiny drops of glue attached to a cables. These also changes color when wet.

    Did the liquid flow underneath the machine? There are two long holes on the bottom of the machine where liquid could possibly get inside and splash the components.

    If your case has vents to allow air into the bottom side vents on the system, then having a case on it is not going to offer much protection from liquid damage in that area.

    If the OJ got under the system, near those vents (which are for intake, not exhaust,) then it’s likely that some got inside, in which case your symptoms would be related to that.

    Taking the bottom cover off and visually inspecting should be enough to confirm liquid damage. It’s OJ, so look for sticky brownish/orangey crap ... with bits.

    Bring to it Apple. Dont tell them about the spill. There are couple of areas with liquid detector. As long as they are not triggered you are safe.

    If i recall correctly from the teardown website, they are located on the left and right of the air vents mentioned by the above forumers, under the trackpad, and on the logic board.

    Good luck.
