Dell Precision 5550 Power Issues Due to Hardware Failure

Confirm hardware-level failures by performing a Dell Hardware Diagnostic test via the F12 boot menu. Look for specific error codes indicating memory (RAM) or CMOS battery degradation. If the system fails to initialize during the diagnostic test or shows consistent LED blink codes (e.g., 2,3 for memory or 3,1 for CMOS), the underlying cause is physical component failure rather than a software configuration error.
