Replacement Keyboard for Pokbook 4420S 4421S 4425S

This new OIAGLH keyboard is a direct replacement for the Pokbook 4420S 4421S 4425S 4426S models. It restores full typing function when the original unit is damaged or worn out. The layout is English as supplied. Buyers needing a different language layout or a backlit variant cannot use this part.

Passive component with no active cooling

The keyboard has no fan, pump or moving cooling parts so it adds no acoustic noise. It draws negligible power from the laptop's internal supply and produces no measurable heat during normal typing. Thermal throttling and fan curves are unaffected by this component.

Questions about this item

How do I install this keyboard on my Pokbook 4420S and which step is often missed?

Remove the battery, unscrew the bottom case, disconnect the ribbon cable, swap the keyboard, then reconnect the cable before reassembly; the step most people skip is reseating the ribbon cable fully into its ZIF connector.

What maintenance or replacement will this Pokbook 4425S keyboard need over time?

Expect to clean dust from under the keycaps every few months with compressed air; if keys become sticky or fail, the whole unit is replaced as a single FRU rather than individual switches.
