HP Plastics Kit 829013-001 is a replacement plastics part listed for HP laptops. The listing describes it as a black cover, making it a relevant spare part for restoring the exterior of a supported device.
The part is listed for the HP ProBook 440 G3. A separate replacement-parts catalogue also lists it for the HP EliteBook x360 1030 G2 (1YY91PA), so the confirmed references cover these two models.
This is a plastics kit rather than a complete laptop enclosure. The available listings identify the product and its model references but do not detail the individual pieces included in the kit.
