Hi Jurek, The E6330 as with most Latitude 6000 series have the power button mounted on the main board. the button you press is actually part of the palm-rest assembly and can be replaced by replacing that part. if you are referring to the actual little brass colored button on the main board, (I have seen them pop off) The only alternative when I serviced those laptops was to replace the main board. I am unaware of anyone reattaching a broken power button to the main board as well as fixing the palm-rest button. That is my two cents worth. Hope you as least find this info helpful in making a decision regarding repairing you laptop. Best Regards, T Golightly
