2019, 16 inch MacBook Pro, the power button does something it never did before. I press it and the screen shows the percentage of battery power left. I have to press it a second time to make it boot up. It started this recently. How do I make the power button simple boot up the computer? It is like I have to hit the button two or more times to make it boot up.

OK, found the answer. Someone went into Terminal to stop the auto-boot when the lid is opened. We use this at a church, and when it boots before we connect the various video outputs, it screws up our third party software, which is why it was set to not boot when opening the lid. So we will just live with it for now, but it's normal behavior when you disable lid-open-boot.
FYI, to control this, use this in Terminal:
sudo nvram AutoBoot=%00 (stops auto boot when lid is opened)
sudo nvram AutoBoot=%03 (resets to default behavior of booting when lid is opened)

Plugged into power... not plugged into power...?
Old issue, new issue, what changed..?
The power button/TouchID has changed a bit yes.
You can open the lid or press any key to have the notebook boot up...
If you are near the mains leave it plugged in, if you need the portability then run on battery only.

This may indicate some sort of hardware issue with the laptop especially if it occurs all the time. It is not unusual to see this happen from time to time....just one of the many quirks of these newer Macs, but I've never seen it occur all the time.
Try an SMC Reset (make sure to read the instructions since the process has changed for the 2018+ Intel Macs).
Try a PRAM Reset (hold for at least two chimes if possible....sometimes it is not possible to get the second chime....yet another quirk).
With a 2018+ laptop, you can also try to "Revive" the firmware, but I've never personally seen the "Revive" do anything to resolve issues with any of our organization's laptops. Even the data destructive firmware "Restore" rarely fixes anything unless the T2 chip is corrupt.

Make sure to disconnect all external devices in case one of them is causing a problem. Also, make sure to connect the power adapter directly to the laptop since adapters/docks/hubs may not allow the full power of the charger to reach the laptop. Also make sure you are using the 96W power adapter. Maybe even unplug the power adapter from the electrical outlet for a minute to reset the charger's internal circuitry. Try connecting the charger to another USB-C port especially on the other side of the laptop and try another charging cable.
If none of this helps and you get this red battery icon all the time when attempting to power on the laptop, then you most likely have a hardware issue with the laptop which will need to be repaired. The best you could hope for is a damaged USB-C port which may involve just replacing an I/O Board (inexpensive part, but labor intensive repair).
Otherwise, most likely the Logic Board is failing, or it may just be the Battery (or maybe both since the laptop is getting to the age where a battery may be wearing out or starting to actually fail).
If I were you, I would get rid of this laptop rather than attempt to have it repaired unless it is just a bad I/O Board(s). The money spent on any other repairs would be better spent towards the purchase of another laptop since the 2019 model (especially the 16" model) seems to have a lot of Logic Board failures. I've seen a lot of our organization's 2019 Apple laptops with Logic Board failures, plus I've seen a lot of reports on these Apple forums where users have had to replace the Logic Boards on the 2019 models at a much higher rate than any other model (especially the 16" model). This is the advice I give to our organization, but the choice is yours of course.
It does this no matter what. New issue, nothing has changed unless it was in one of the Ventura dot updates. But I've got three MacBook Pros, this is the only one doing this, on batter or on AC charger, does the same thing. I've never seen a Mac do this ever.
I never said "red battery icon". I get a battery charge level icon, it's green, not red. Everything else works just fine otherwise. I may have to run it by the local Apple retail store to be checked. But yes, even if I hit the space bar to power on, same thing, I'd have to hit it, see the battery level indicator, let it go back to sleep, then hit it again. So stupid...
How do I make the power button simply boot up my MacBook Pro?
