Swift SF314-51-57CP running Windows 10. The right-click and click-drag to select (e.g. to highlight a section of text or to rearrange the tab order on a browser) stopped working on my touchpad. These functions still work fine if I plug in a USB mouse. Left click functionality seems to work fine, and I can do the two-finger tap to bring up the left click menu, but clicking the lower right corner doesn't work.
I have tried these steps:
- Toggled touchpad off/on
- Toggled the "Press
lower right corner of touchpad to right click" option in the touchpad settings
- Uninstalled/reinstalled the ELANTECH drivers using the drivers on the Acer support site
- Reinstalled the HID-compliant touchpad driver (using the "Browse my computer" option for locating drivers)
- Toggled the BIOS touchpad settings from "Advanced" to "Basic" and back again
- Disconnected/reconnected the ribbon cable from touchpad to the motherboard.
- Cleaned the touchpad with compressed air and contact cleaner
- Installed new touchpad (It exhibited same behavior as the old touchpad, so I put the old touchpad back in).
The only thing I haven't tried that I've seen suggested is to update the BIOS, but at this point, I don't see how this could be a BIOS version issue. I feel like this could be a calibration issue (when the problem started, the right-click spot had "drifted" to the bottom middle of the touchpad before it stopped working entirely a few minutes later), but there is no calibration tool like I've had on older laptops. I'm out of ideas. Does anyone have any suggestions? The warranty period has long since expired.
