My MacBook is not going beyond the logo and progress bar on startup. Am I looking at replacing the battery or the SSD?
좋은 질문 입니까?
Does it show the loading bar then turn off? what happens after the loading bar.

The progress bar and the logo stayed on without doing anything else. It stayed that way for over an hour today.
I put three calls into Apple Care. Did the Command S, the Shift Control Option, the Command R and, finally the Command Option R. The last one worked. It required me to download and install macOS High Sierra to replace El Capitan. Took a while and now it works.
One of the things the Applecare folks and I discussed was the possibility of having to replace the "CMOS battery?" Didn't know I had one.
My next step is to try and restart it. Wish me luck

I would restart the system holding the D key to get to the onboard diagnostics to see if something comes up. If that works, I would then do the Command R to get into the recovery petition to repair the drive.

Depending on what the computer does after the progress bar it could be the SSD if it is then use this link Internal hard drive disk not recognized
@ggarofalo1 - Almost ;-}
The link you have here is for an older SATA HD based system whereas this is a PCIe SSD based system.
