Macbook Pro doesn't often turn on

I'm having very strange issue with my Macbook Pro 2015 model lately. What exactly happens is almost all the times for past 10 odd days, Macbook wasn't starting in the morning however as soon as I used to take it to an air conditioned room & stay there for a couple of minutes, it used to start. Also, hair blower is quite solving this issue, too. If I blow some hot air on it for 15 seconds, it starts.

I have recently relocated to more humid area, humidity here ranges here from 70-90% & I really suspect it is the issue of humidity. Though I have been staying here for past two months, problem with the Macbook started just 10 days back.

Can anybody put some help here what can be done to solve this permanently?
