This is a keyboard (including the bottom plate) purchased new from DELL in 2022 for an Inspiron 14 5425 and used for approximately 2 hours per week. The exterior condition is very good, but one of the bottom plate tabs (see photo 8) is broken. It should still be securely fixed with screws, so I don't think it will be a problem. I have no way to verify its operation, so please purchase this as a "junk item." Therefore, by purchasing, you agree that it is a junk item. I do not have any specialized knowledge, so I cannot provide any after-sales support. When listing this item, I may not have provided sufficient information, so please ask any questions you may have beforehand. I hope someone who needs this will purchase it.
