Hello,
I have a Aspire ES1-512-26SJ out of the box and installed Win 8.1 OS.
After that I went through the device manager and installing all the driver for the "unknown devices" from the Acer support page. After that I notice that the touch pad is not working at all.
The Acer support side for ES1-512 driver does not list any touchpad driver. For the ES1-511 driver from Synaptic and Elan are available. I downloaded both and tried to install but the touch pad doesn`t get working.
After a call with the Acer premium support, I downloaded the latest driver version from the Synaptic page. Unfortunately, the installtion was aborted.
So, I would be happy to get any guidance how to get my touch pad working.
