The technician from the specialized shop where I bought the laptop was very nice and verified that there is indeed a problem with the touchpad. It isn't easy to diagnose because the misbehavior tends to come and go in waves. It appears to happen more frequently once the laptop warms up, after 15 minutes or more of use if…

Traveling tomorrow to see the technician at the shop where the computer was bought. Will keep you posted on how it went.

Here's a video showing how scrolling with two fingers will cause bouncing due to touchpad erratic behavior. In this case, it happened three times in a roll. https://www.dropbox.com/s/ngzhkcp9p0j0ru2/Scrolling.avi?dl=0

Thanks for sharing, I've started a similar process here to recover my financial losses plus professional and moral damages.

CatalinR, so I see that I'm not the only one having troubles with a negligent Acer SAV (see the thread on my problems with the Predator G9-793 touchpad): http://community.acer.com/t5/Predator-Laptops/Predator-G9-793-with-erratic-touchpad/m-p/482842#U482842

As promised, here is the link to the video made on February 10 after the third SAV "diservice" exchange, showing how the touchpad fails sometimes to open the context menu (1:21 and 1:25) and how the arrow sometimes jumps when I use two-finger tapping (1:32). Later I'll post a video showing how the same touchpad malfuntion…

Today I received the computer back after I sent it for the third time to the Acer SAV in Angers. As a reminder, the computer was bought in December and is covered by a two-year global warranty. The technical repport seen in the picture below (in French) tells me to "spread my fingers." It's quite surreal, here's my…

Found a way to have the computer sent back to me, once it arrives I will update the bios with v1.09, test it for the fourth time, and post a video with the results here.

Here is a video that shows the cursor jumping when tapping with two fingers. You can see erratic jumps at 3 and 19 seconds. https://www.dropbox.com/s/l8uy4v5b0vkme9f/VIDEO0052_sec_3_19.avi?dl=0

Thanks a lot for your reply. I understand what you mean, our Lenovo Y70-70 touchpad is very sensitive to light touching, but not erratic. What you say confirms my guess that it's a hardware fault of this particular Predator, not a design flaw. Unfortunately the Acer service center is located in Angers, not where I live, so…

Here's a short segment of many long videos that I collected documenting the problem: https://www.dropbox.com/s/00d1cvxkl4fe45v/VIDEO0052.avi?dl=0 As I scroll using two fingers on the touchpad, the app column of the start menu will jump up, bounce back, or stop suddenly due to erratic touchpad information being sent to the…

The technician on the phone today told me, after using the touchpad for 30 seconds, that it's perfect. He rejects my claim that the computer cannot be used as it is. No way to convince him from far, over the phone, that the problem is real and makes it impossible to use the machine. He informed me that the case will be…

Had a second lady from maintenance on the phone. She offered to have one of the technicians calling me on Monday to go over the computer misbehavior. Let's see now if the fixing will advance. [edited to comply with guidelines]

Just had a very disagreeable conversation with the responsible for the maintenance service of Acer in France (where I live). They say that the computer is not defective, when I have videos that show that it is defective. The lady insists that I should "spread my fingers" to use the touchpad, when the problem persists even…
