Hi, 

i have a lenovo ideapad yoga and I noticed some green ish liquid between where the cord and ac adapter meet/connect. What could be the cause of this? Could I be overreacting

Might be shorting out, or as you said - overheating.  Can you try another brick awhile to see if it's only the ac adapter is faulty, and not also the laptop contributing to the problem in some way?

That green stuff is probably some kind of seal or adhesive. It definitely should not leak out of the adapter!

 

How hot is the ac adapter brick?

That's a definite fire hazard ! Spend the $15 to $30 and get a new adapter.

If the transformer shorts out in that thing you could do some serious damage to your comp, too.

Computer software won't tell you the temperature of that power supply. When I meant hot, I meant is the actual ac adapter brick hot to the touch. Can it be handled or is it so hot you could fry eggs on it? If it is really hot, it may be defective and need replacing.

Lenovo is pretty cheap these days. It does not surprise me you got a bad ac adapter. It definitely sounds like that adapter needs replacing. I wouldn't use it anymore if I were you, sounds like a fire hazard.

 

Maybe Lenovo should recall those ac adapters as well.

Unfortunately it is not possible to get any useful information from your photographs.

 

Is it possible that your that this connection has got wet? - copper (or brass) corrosion would produce a green liquid or deposit.

 i really doubt it has gotten wet, im very careful. it looks like green liquid, if we assume this is true, what should i do? how can i solve/fix/lessen/stop the problem?

I would disconnect the adaptor from the mains supply, separate the connection & clean out the green liquid (using paper wipes/cotton buds  or similar, possibly dampened with water or an alcohol e.g isopropanol or methylated spirits)   After ensuring that all parts are completely dry then refit them & test to see if further "leakage" occurs. If you have an alternative mains cord available I would use that & discard the original. 

 

If the problem recurs then replacing the ac adaptor & mains cord would seem sensible.

Don't know how much I trust lenovo anymore, they were caught installing bios backdoors, and have very frequent recalls.

This isn't your adapter but I thought you might have fun watching and see what is likely leaking....the capacitors.

I know you won't attempt this repair and strongly suggest you purchase a new adapter.

  It might be worthwhile to not only purchase a new ac brick, but also, to take the laptop to a local computer shop and let them use their hard-ware testing stuff on your "power-train" [from the ac adapter jack to the motherboard circuitry to the battery, and back again.  Yeah, it costs, but would a laptop meltdown.
