insertion point jumps when typing

[janissa]

i just bought a new hp pavilion dm4 laptop (model dm4-2180us, windows 7). whenever i'm typing, the insertion point jumps.  i'm very careful not to make any contact with the touchpad, and still it jumps.  it seems to happen whenever i'm typing, regardless of the program.  the only change i've made since i bought the laptop was in the device manager, i rolled back the mouse to ps2.  i did this because the touchpad kept freezing, and that was the recommended solution to that problem.  it worked, but now i'm having trouble with the insertion point.  i appreciate any help you can give.  thanks!

Please follow steps in sequence

1. Install latest BIOS from here
2. Go to Control Panel > Programs and Features and uninstall Alps touchpad driver, restart the Notebook and install updated touchpad drivers from here

thanks, kamat_hp.  this didn't solve the problem completely, but it is much much better now.

I found an HP link ostensibly for resolving this problem.

It promised a path to finding new bios.

The link took me to a Welcome to Customer Support page.

There was no path to updated bios.

There was a search box in to which I typed the subject of this message.

None of the pages and pages of search results regarded bios.
