Hello,
I am the owner of an Acer Aspire VN7-591G Black Edition laptop. Today, upon startup, my trackpad no longer responded to my touch or clicks. First, I pressed Fn+F7 to see if I had just accidentally disabled it but that was not the case. I plugged in an external mouse into the USB port to navigate through my laptop and once in Device Manager, found that my trackpad was not listed under the Mice and other pointing devices section.

Also, under Mouse Properties, my trackpad does not show up. HID-compliant mouse is the external mouse I am currently using.

I am unsure how to fix this. If anyone has any ideas that could help, it would be greatly appreciated
