Questions about this item

How do I install the YMHTX power button board on my Latitude 3189 without damaging the fragile ribbon cable?

Disconnect the battery first, remove the bottom case screws, gently unplug the old board cable from the motherboard connector, route the new cable along the same path, and press the connector straight in until it clicks.

Will the tactile switches on this CAV00 LS-E372P board wear out and need replacement later?

The tactile switches are rated for typical laptop lifecycles; if a button becomes unresponsive or sticks, the entire YMHTX board is replaced as a single unit.
