Questions about this item

Will the CY779 motherboard fit into my existing Latitude E5400 chassis and reuse the original heatsink?

The CY779 is built for the Latitude E5400, so it matches the chassis mounting points and original thermal layout for direct heatsink reuse.

How can I confirm the CY779 board is functioning correctly after installation?

Power on the system; a successful POST, BIOS version display, and Windows loading without errors indicate the motherboard is operating as intended.
