Questions about this item

How much power does the W180F center control cover draw when the Precision M6400 runs all day?

The cover contains only the fingerprint reader circuit board, power button circuit board and LED light circuit board, so its power draw is negligible compared with the laptop's main components.

What existing laptop parts must I already own for this W180F cover to install and function?

You need a Dell Precision M6400 chassis with the matching center control mounting points and the motherboard headers for the fingerprint reader, power button and LED cables.

Will the W180F cover work if I keep the original Precision M6400 palm-rest and keyboard?

Yes, the cover is designed to fit the standard M6400 center control opening, so it aligns with the original palm-rest and keyboard without modification.
