The HP L70825-001 touchpad cable is a replacement connection cable for the touchpad in the HP Chromebook x360 12b-ca0000. It links the touchpad with the system board as part of the laptop’s internal touchpad assembly.
The service guide specifies that the cable attaches to the keyboard/top cover with adhesive and includes double-sided adhesive. This helps secure the cable in its position during installation.
The cable is a separate spare part from the touchpad: the touchpad kit does not include it. This listing is for the cable identified by part number L70825-001.
