Hi Steve,

it is normally not possible to repair a broken plastic sensor pad. You can try to replace ist with a sensor field from a damaged computer of the same kind (e. g. same manufacurer and model from the same time). For the T432 a Turbo Star or Superstar may work. Best is to replace the complete cover, because it is difficult to extract the foil without damage.

Parts from different manufaturers (e. g. Excalibur) will not work, because the cable and and the pins are different.

Regards
Achim
