How do you disable internal battery in a PC?

To disable the internal battery in a PC, you typically need to shut down the computer and disconnect it from the power source. Open the case to access the motherboard, locate the CMOS battery (usually a coin-cell battery), and carefully remove it. Some systems may also allow you to disable the battery through BiOS settings, but physically removing the battery is the most straightforward method. Always ensure you follow safety precautions when working inside your PC.
