Laptop Bottom Cover for HP 250 G7

This replacement bottom shell fits HP 250 G7, 255 G7 and 15-DA models with the TPN-C136 chassis code. The part number L50290-001 identifies the exact grey chassis supplied without an optical drive bay. It restores structural integrity after damage or during a full teardown. Installers should verify the chassis code before ordering.

Sustained thermal and mechanical behaviour

The cover acts as a passive heat spreader for internal components during long workloads, so its metal mounting points and vent pattern must stay flat over time. Warping from repeated heat cycles can stress the motherboard or block airflow, leading to throttling. The part is not for units with an optical drive or a different chassis revision. Builders needing a top lid or a version with an ODD cutout should look elsewhere.
