power button doesn't work correctrly

Hello,

I have the MacBook pro early 2015 and the battery was dead after 4 years so I decided to order a new one and change it. So I removed the old dead battery. After checking that nothing was destroyed by me I ordered a new one. After some weeks without the battery, while I was using my MacBook I spilt a little bit water to my laptop. I immediately disconnect the MagSafe and my pc was off. After that, I blow with compressed air the keyboard to dry the keys. Subsequently, I took the motherboard and clean it with alcohol (I haven’t isopropyl alcohol). Today I noticed that the power button doesn’t work unless I disconnect the MagSafe, pressed it for 1-2 seconds, plug in the MagSafe and then press the power key.

Any ideas??

Thanks in advance

May be try to closely look with a ‘lens’ or microscope for any short/damage to the DC in board. Or replace it.

Careful: may be you can cause more damage by opening and analysing. At least it works now!!!

I found that the button doesn't work at all. If you disconnect the MagSafe and reconnect it without the battery it will turn on. This is the reason that it boots.

I probed the pin five of the connector of the keyboard and pressed the power button, it hasn't resistance between the ground. Is there a probability that the only key destroyed by the water is the power button??
