Sony Vaio V505AP - Alps Pointing Device - SP2

  juvens 15:12 30 Jun 03

My laptop runs Windows XP - fully patched.
After it has been running for a while the pointer becomes sporadically unstable and moves around the screen without any apparent link to my finger movements on the touchpad.
The PC has been back to Sony for repair; I have tried uninstalling the pointing device; I have tried removing the notorious service patch 811493; I have updated the Alps pointing device driver. Still the trouble persists.
Sony are now suggesting the dreaded full restore - but I wonder if anyone has ideas for a less drastice solution.
