Acer trackpad and copper wire

Dear all

The trackpad on my Acer Es1-311 did not work so I bought a new one, when I replaced the old one, a copper band broke and now the new one does not work.





The new one does not need the copper band and will it work?

Do you know what the copper band does? (in the picture you can see the wire with the old touchpad)

I really hope you can help.

Re: Can you help my with my trackpad?

My laptop's trackpad started jumping here and there around the screen when I moved it slightly, and it even caused unpredictable actions without my clicking. I solved the problem by connecting an external mouse via usb. It is much easier to operate. I hardly ever use the trackpad now, and when I do it rarely misbehaves. Reason unknown.

What do you mean with "copper band"? The 8 circuit flat flexible cable? Yes it's essential and must be replaced if broken.

It is the broken band you can see in the first picture in the corner of the trackpad.

Where do I buy a new one?

And can you see the difference between the old and new trackpad? Will it work?

In the "corner of the track pad", there's an adhesive metal fabric band connecting a ground pad with the frame metallization. It has been apparently replaced by a different ground connection method in the new device and won't be needed any more.

Purpose of the ground connection is most likely only EMI suppression, not related to mouse pad function.

If the mouse pad doesn't work, I would expect either some electrical/functional incompatibility or a broken flexible cable.

By the way, are you sure that the old mouse was actually defective?

Yes because the mouse would sometimes stop working and I tried all drivers and operating systems, how do I find out if it is compatible? And where do I buy a new connector?
