Sorry to hear about your problem lm2 and dkwatts.

Talking about electronics, I believe it would probably have to do with the heat generated by the electronics, it is possible, but I think that would also mean that you left your tablet outside or on the grass or in some jungle. I'm not sure how such a "bug" (lit. lol) crept into your tablet otherwise.

At first I thought it might have been battery acid, Check your battery, make sure it's fine. It should be noted that there are other "batteries" in the tablet (capacitors mainly). If one of those blew or leaked, then you're in for serious trouble (RMA type).

I'm not sure I can offer any other useful advice. It is quite rare that an electronic device starts leaking slime. Either way, it can't be good
