This replacement keyboard fits HP ProBook 4440S, 4441S, 4445S and 4446S laptops. It matches part numbers 701282-001 and 839398-001 and uses a US QWERTY layout. The unit is supplied new with an integrated frame and a silicone keyboard film is included.
Installation Notes
The keyboard arrives with its frame attached so the whole assembly can be swapped as one piece. No backlight is present, so there is no backlight cable to route. Verify the exact model and compare the product photos before fitting because connector placement varies between the listed models.
Interface Limits
The keyboard connects through the laptop's internal ribbon cable, which carries only key-switch signals and draws minimal power. It does not add any external ports, wireless links or lighting control. Buyers who need a backlit keyboard or a different regional layout will not be served by this part.
