What is the purpose of performing an RTC Reset?

Performing an RTC (Real-Time Clock) Reset serves the purpose of recovering from situations where the system is unable to complete the Power-On Self-Test (POST) or boot into the operating system. The RTC is responsible for keeping track of the current date and time and is also involved in some hardware configurations and settings stored in the BIOS.

When a system encounters a No POST or No Boot situation, it may be due to incorrect BIOS settings or corrupted configurations that prevent the system from starting properly. The RTC Reset clears these settings and restores the BIOS settings to their default values, allowing the hardware to initialize correctly during the boot sequence. This can often resolve issues that inhibit the system from completing POST or reaching the operating system, making it an essential troubleshooting step.

Other options, such as clearing user data, updating BIOS settings, or reinstalling the operating system, do not directly address the immediate need to resolve boot issues or restore functionality at the hardware initialization level. Therefore, the RTC Reset is specifically targeted at fixing boot-related problems.
