You are not shutting it down completely. CP has a battery on the motherboard that is there to power the real-time clock and to keep bios setting.

For a desktop, it is often a button cell battery that is easy to switch but in a laptop, it is often soldered on.

Just looked at a motherboard like [one of ASUS’s current models](https://www.asus.com/se/Motherboards-Components/Motherboards/ProArt/ProArt-B550-CREATOR/) and the battery is trivial to spot. It is the large silver-colored circular you seed in just to below the initial P in “ProArt B550-CREATOR” that is printed on the motherboard.
