RTC Coin Cell Battery
The RTC battery maintains the CMOS memory which holds BIOS settings and hardware configuration. When this battery fails, the BIOS cannot verify its checksum during the Power-On Self-Test (POST), leading to a diagnostic red-light sequence and a system halt. Replacing the cell restores the constant voltage required for the CMOS to retain its operational logic.

Motherboard / System Board
If the CMOS battery is functional but the BIOS/ROM failure persists, the Serial Peripheral Interface (SPI) flash chip or the Southbridge controller on the motherboard has likely suffered a hardware-level corruption or thermal logic failure. Because the BIOS chip and central logic are integrated into the high-density PCB, the entire assembly must be replaced to restore the pre-boot execution environment.

DDR4 SODIMM RAM Module
Dell diagnostic codes in the 2,x series (specifically 2,3 or 2,4) indicate memory detection or failure issues. In high-performance laptops like the m15, thermal stress can cause solder fatigue or logical failure in the RAM modules, preventing the motherboard from initializing the system memory and triggering a red-led diagnostic state.
