2016 12" MacBook won't turn on So, I had my 12 inch MacBook plugged into an external monitor (with Bluetooth keyboard and mouse) and was working on it normally, when suddenly everything became really slow and unresponsive, after waiting for a while for Force Quit to work and with nothing happening I decided to force shut-down the machine. 

When it was starting up it asked me for a password after entering it the login screen froze after waiting for 5 min I force shutdown this as well. 

But now the machine just won't turn on at all. What can I do?
I resolved the issue by doing an SMC reset.
