Laptop not turning on

[Rchawla]

I spilled milk on my laptop( Acer) 60-70ml lid closed
Cleaned it and let overnight it it was working fine next day
But after 1 day it is not turning on just blue charging light is present

First thing I'd go with is you need to replace the motherboard. Spilled milk = something is damaged. Depending on what got in where it may have gotten in the CPU socket, RAM, all sorts of parts need to be checked.
