They only thing that I am worried about is if I messed up the aluminium/tin foil sheet on the top left corner of the touchpad. Ps: I opened the pc at least 10 times and all cable are connected. I tried to attach a Bluetooth mouse and follow what you have said for the other user but I do not see dell touchpad. Funny enough, I even re installed the old touchpad and the hilariously, the clicking physical function was back fixed but the the touchpad is completely useless. The pointer is gone and the clicking function only works physically but I can’t click on anything since there is no pointer on the screen.

I tried to switch cable between my old trackpad and the new trackpad. I installed it personally and for a second it worked and then it stopped. The clicking function of the touchpad was not working ( but I could move the pointer normally using the touchpad) so I ordered a new one.
