Mac doesnt boot up without using SMC bypass

My MacBook Pro 13" with Retina Display won't boot up at all- the power button doesn't do anything. I can plug in the charger and it shows the lights, and it even changes colors briefly when I attempt to do an SMC Reset, but it won't turn on.

The only way to make it turn on is via the SMC Bypass, but this is hardly a desired result as the computer grows incredibly slow.

This issue happened with me two nights ago, but my computer had run dead overnight and it was able to work like normal the following morning, no need for SMC Bypass. This morning, though, it won't turn on once again. I'm not sure what the issue is, as the computer worked fine and essentially worked fine with SMC Bypass, but I'm not sure what's causing the issue, what the issue is exactly, and how I could go about fixing the issue.

What is an "SMC Bypass?"

Hi! An smc bypass is a different form of booting up the computer where, as it's called, you bypass the SMC. As a result though, the laptop can't run without the battery charger plugged in, and it runs much slower with its fans on blast, no battery display, and no keyboard blacklight (because all of these run via the SMC, and you're running the computer without the SMC).

You seem to be somewhat confused. There is no such thing as running without the SMC. The page you linked explains how to reset the SMC, not "bypass" it.
