Question My laptop doesn't turn on and only the airplane mode LED blinks ?

1) First and foremost, stop using the magnet to power it on.
2) Pressing the power button continuously isn't going to magically make it come on. You are likely stopping it from POSTing correctly by doing that.
3) Since water was spilled on it and it started shutting off on its own, it likely has gotten water damaged at the motherboard level.
4) If you simply press the power button once and let it go, what does the laptop do?
