Status Indicator Board for Latitude 5400

This genuine Dell LED circuit board displays power, battery, and hard-drive activity status on the Latitude 5400 laptop. It replaces a damaged or non-functional indicator assembly using part number 4TNV6. The component restores the visual feedback users rely on for basic system monitoring. Installation returns the front-panel lights to factory behaviour.

Sustained Operation Reliability

The board is designed to operate continuously while the laptop is powered on, reporting status changes without drift or flicker over long sessions. Its solid-state LEDs and flexible flat cable maintain signal integrity through repeated thermal cycles. No moving parts are present to wear out under constant use. The assembly meets the same endurance expectations as the original factory part.

Connector and Compatibility Limits

The flexible flat cable uses the Dell-specific EDC41_LED_BOARD_FFC interface keyed for the Latitude 5400 chassis. It will not fit other Dell models or third-party laptops because the pinout and mounting tabs are unique to this platform. The part number 4TNV6 cross-references to alternates NBX0002FH00 and LS-G891P for ordering verification. Buyers needing status indication for a different laptop must source the correct model-specific board.

Questions about this item

Does the 4TNV6 LED board cable draw extra power when the Latitude 5400 runs continuously?

The LED indicator board is a passive component that lights only when the system reports power, battery or drive activity, so it adds no measurable load during all-day use.

What existing part must be present in the Latitude 5400 for the 4TNV6 cable to function?

The motherboard header that carries the status signals must be intact; the cable simply bridges that header to the LED board.

Will the 4TNV6 status indicator cable work if I keep an older Latitude 5400 chassis and screen assembly?

Yes, the cable matches the Dell Latitude 5400 design (part numbers 4TNV6, EDC41_LED_BOARD_FFC, NBX0002FH00, LS-G891P) and fits the original chassis and display lid.
