Re: Aspire V3-772G touchpad behaving erratically

Good news - I survived a full two weeks without having the touchpad go mental.

Now, it's relapsed again, and the symptoms are:

- tapping doesn't work at all

- clicking anywhere on the pad (left or right) results in a right click

- two finger scroll doesn't work at all

- the cursor isn't jittery, but the cursor doesn't always move - every 2nd or 3rd time I move my finger the cursor decides to move

- I can sort of left click by clicking while resting three fingers elsewhere on the touchpad

All in all, this is completely ridiculous.

Hi,

I have an Aspire V3-772G (NX.MMCED.054, i7-4702MQ/12GB/GTX850M/256GB/1TB) laptop that I got around a week ago. It's got a Synaptics touchpad with the Windows 8.1 driver version 17.0.6.17.

Yesterday as I turned on the laptop, the touchpad behaved erratically:

- the cursor moved to the left by itself and jittered, UNLESS I placed my finger on the touchpad and held it still

- it kept registering left clicks by itself even if my fingers were nowhere near the touchpad

- I could not click the left button (tapping kind of worked though)

- if I clicked the left button, a right click would happen

So I disabled all the swipe/tap/click/etc features in the Synaptics settings. No effect.

Then I uninstalled the Synaptics driver that came with the laptop, rebooted, and tried the default PS/2-compatible mouse driver in Windows. The jittering got even worse.

Then I installed the older (Windows 8) version of the driver (16.3.4.5) from the Acer support site, and rebooted. No effect. Disabling the touchpad features didn't help either.

Then I uninstalled the driver, rebooted, and reinstalled the newer ones. No effect, still erratic.

At this point I went to bed, furious at my new laptop.

As I woke up this morning, the touchpad seems to be working ok again!

My question is: has anyone got any idea why it threw a hissy fit? Is this common? Or is the touchpad defective?

Best regards,

Reed
