Acer Laptops - Cursor Jumping around whilst typing typing.

[mbird]

Were having a problem with all of our Acer Laptops (5720/5630ez) where when staff are typing on them the cursor will jump backwards - meaning when there typing it goes up a paragraph, or across a few cells in a excel spreadsheet.

Anyone heard of this before/Know how to fix it?

As acer aren't particularly helpful and i don't really want to send 50 laptops back ....

Usually due to people touching the touchpad lightly during typing. Try seeing if the laptops have a 'disable the touchpad' button, sometimes it is just a square symbol.

[mbird]

they don't unfortunately, a teacher did say they used there pointers to type (thus avoiding the touch pad) and it still happened

[Jamo]

Have you 'massaged' around the touchpad to see if its loose connections on behalf of the touchpad cable?

[mbird]

I haven't no - sounds interesting. How do i massage the touch pad?

[Quackers]

We have had this on other laptops, like the HP 530. Make sure they have the synaptics mouse driver installed (or equivlennt), then in the utility there is a sensitivty setting, to stop it happening.

haha just press around the touchpad to see if its pressure on the face plate that is causing it. Post above is v correct about sensitivity, this can cause issues where leaning on the faceplate can cause a mouse press. Reducing sensitivty may sort some of the issues out.

Yes, this happens on my acer work laptop and it is an absolute pain in the backside.

 

I disabled the touchpad and use a mouse now, it's just easier and less dramatic than crying when you completely type the wrong stuff into a terminal.

TouchFreeze perhaps?

[SimpleSi]

I thought it was just me doing something wrong when I was using mine

 

Good job I've ordered mice to go with the 15 I've just ordered!

This happens on my Acer laptop (model 6930G), although its only started happening since i installed win7pro64bit which i find strange. Never happen on vista which i had installed for 8 months.

 

It is real pain in the ass though !

 

Would love a fix

Just came across the following AutoHotKey script that does the same thing as TouchFreeze (but more reliably according to the comments).

Thanks for that.

 

Just set it up, will see how it performs

to disable the touchpad on the 5720, you only have to press Fn + F7. I accidently hit this once and spent three hours trying to fix my touchpad!

Wow, that was too easy! There it was, staring me in the Fn face all this time! Thanks.
