MacBook Pro Reset Itself/Not Working Properly

About a week or two ago, I was using my MacBook Pro when the battery died. Thinking nothing of it, I let it charge for a while, but when I went to turn it on again, I found that I couldn't log in or use the touch-finger option. I kept receiving an error that my login ID/Apple ID was incorrect. I tried to restart the computer a few times, but kept receiving an error that I was locked out for 1 minute due to entering my password wrong (which I was not). I finally manage to reset it, only to get logged in and see that all my settings were reset. My Apple ID needed to be reset because everything was disconnected from my laptop. My wallet was no longer set up, my finger touch thing was gone, and on top of all of that, the computer has been somewhat glitchy since then. I've tried to restart it a few times, close everything out, charge it, etc. I still have all my documents and photos, but the computer is still kind of glitchy.. What is going on? Is this a hack? Why did this all happen just because my battery died?

MacBook Pro (2017 – 2020)

There are a number of internal parameters including the date&time, external display settings, Apple-ID information, and much more, that makes your Mac simple to start up and use every day.


Most of that information is stored in the battery-backed Parameter RAM. On a desktop Mac, a separate lithium coin cell battery is used for Parameter RAM backup. Oon MacBooks or all varieties, the Main battery is THE battery, and if you let it run too low, you lose all those Parameters.


You have not been hacked.

That computer is a battery-CAPABLE device. It is not optimized as a battery-operated device. (It is NOT an iPhone.)


Your computer performs best when connected to AC power. It can use the full output of the Power Adapter AND when doing especially challenging work will also freely "borrow" power from the battery. In some cases, even with the power adapter connected, the charged state may decline during stressful work.


When used only on battery, your computer has no extra cushion of power, and may perform more slowly. However, for ordinary non-stressful tasks this may not be objectionable (possibly not even noticeable.)


In general, you should ALWAYS connect AC power when it is possible to do so, and only run on batteries (which could be somewhat slower) when no AC sources are at hand. Your Mac will NEVER over-charge.
