+### Prevent Apple silicon laptops from turning on when opening their lid or connecting to power
+
+Mac laptops with Apple silicon automatically turn on and start up when one opens their lid or connects them to power.
+
+From macOS Sequoia 15, one can change this behavior.<br/>
+This will **not** affect one's ability to use the keyboard or trackpad to turn on the Mac.
