DELL Latitude C400 Embedded Solution Motherboard PIII 1.2GHz 8N817

Dell Latitude C400 motherboard with 1.2 GHz PIII

This Dell Latitude C400 embedded motherboard integrates a 1.2 GHz Pentium III processor for legacy laptop repair. It suits technicians restoring period-correct C400 systems or maintaining vintage industrial equipment. The board carries part number 8N817 and cross-references to 3J051. No additional components are included beyond the system board and fitted CPU.

Compatibility checks before ordering

Verify the chassis is a Dell Latitude C400; the supplier notes the part number does not need to match across C400 variants. Confirm the existing cooling assembly, display cable and I/O daughter boards align with this revision. Ensure the BIOS version supports the 1.2 GHz processor stepping. Check that the power jack and battery connector match the original layout.

Replaces failed or slower C400 boards

This unit replaces a defective C400 motherboard or upgrades a lower-speed Pentium III variant within the same platform. The jump is worthwhile when the original board has damaged VRM circuitry, cracked traces or a dead CPU socket. It restores full 1.2 GHz operation without requiring a full laptop replacement. Buyers needing dual-core performance, modern I/O or larger memory capacity must select a newer platform.
