Is it possible the liquid contact indicators could be affected by moisture in the air?

We have not ever spilled anything on the laptop; however the display went dead and we took it in to Apple for a replacement. To our dismay they told us we would have to pay $750.00 because the Liquid Contact Indicators (LCI)suggest it was mal treated and that water got into it.


I wonder if anyone knows if the LCI could be affected by moisture in the air?


Thanks.

Absolutely, airborne moisture can set off the sensors. However, it almost takes human action for it to happen. Hence, even then Apple will say it is likely a user fault.


You see, if you were to say keep your MacBook Air in the cold, dry trunk of your car on a winter day/night, long enough for it acheive a low temperature in comparison to a relatively warm indoor temp. Then abruptly bring that MacBook into a warm, humid (comfortable) room. Immediately you would have condensation on the notebook. If the temp and humidity change is great enough, then the MacBook Air could actually get almost "dripping" wet, inside and/or out. Likely the inside would get the worst of it, since evaporation of the condensation would be more slow.


When transfering a cold notebook into a warmer environment, do so in a sleeve or case, so that the rewarming is slow enough for the condensing moisture to not accumulate to any harmful extent (or set off the sensors).
