Touchpad can not smooth to move mouse

[Luna.Huang at quantatw.com]

We have a new discovery.

The original, image is 526.img and 406.14.img, bios is Q2C18.

The touchpad can not smooth to move mouse even we have recalibrated.

Then install image return to 406.img and bios Q2C11.

The mouse of machine can normally respond.

Last we afresh install to 526.img, 529.img and bios Q2C18.

The original event does not happen again.

Now we have two machines have the issue.

We will set them a long time and watch the event will happen again or not.

Does any one have ideal about it?

Luna

Sorry I forget to say.

Bios is Q2C18.

My machine is using shipping image (406.XX.img). 

Install image to 526.img has the same question.

I have tried the recalibrate but it dose not really work.

The mouse does not respond.

When I do an action that draw a line from upper left to lower right on GS.

The mouse just moves a little or does not move on sugar frame.
