Instructions say to turn vision pro ON by pressing left button until Apple logo appears. This does not work.

I was curious, so I searched for the "official" Apple instructions. They "cover the bases" and assume you don't have the battery attached (eye-roll):

1. Connect the battery to Apple Vision Pro. When you hear a tone, it’s ready to wear. See Connect the battery to Apple Vision Pro.
2. If you connect the battery and you don’t hear a tone after 30-45 seconds, press and hold the top button for a few seconds to turn on your Apple Vision Pro.

Despite what the "Genius" said, Apple doesn't say to "hold it until the Apple Logo appears." Like you, I seldom want to detach the battery and haven't done so in over two months.

Turn on and set up Apple Vision Pro - Apple Support

I also thought this at first... just press the button for a couple seconds and release.... don't keep holding it down. Then wait for it to boot up. It takes a while (~30 seconds?).

I usually press the button a minute of so before I put it on so I don't have to wait "in the dark" while it boots. I think it turns off if you wait too long, though. I also suggest using Siri to shut down (Siri... shut down). Using Siri to restart is also good, if you are experiencing problems.

So.... does the method I described not work for you? I have no idea why Apple would say to "keep holding" the button until the Apple Logo shows up. Just press the left button for 1-2 seconds and wait. And relax.

If this does not work I think you have a software/hardware issue.

I included the link where I got the info.

You still didn't say if my suggestion worked for you
