3830TG keyboad error

Hi all,
I bought an Acer TimelirneX on last Saturday in Canada. However, there are many errors when I type. For example, I can't type the following sentence with a normal typing speed:
"There was a problem that caused parts of the windows Live id sign-in assistant to be disabled. You might not be able to sign in to Windows Live in some programs".
When I type with a normal speed in Notepad, the cursor moves by chance to many different positions in a line or moves to other lines or highlight some words.

On last Saturday, I thought that the bilingual keyboard caused this error. However, after fixing the bilingual problem ( Turn the left backslash key into a Shift key! (turn bilingual keyboard into a US keyboard) - YouTube, this error still exists.

The only solution for this error is that I must type very slowly. (even when I'm typing this message, the cursor moves automatically in different lines, makes me very annoyed)

Would you please help me to solve this error? Thank you in advance.

 

I know how to fix this error right now. The reason why the cursor moves automatically to arbitrary positions when I type texts is that my hands touch the "touchpad". In my view, the position of touchpad isn't reasonable. To solve this disadvantage, I turn off touchpad while typing.

 

Almost any notebook touchpad will do that. Synaptics models will let you set a delay that solves that problem. For Alps touchpads, get Touchpad blocker which does the same. Touchpad Blocker - software to automatically lock/disable touch pad while typing on notebook keyboard I use it on my3820TG.

 

Hello Bronsky,
Thank you so much. The software is very useful.
