3. Touch pad's left click stops working

A true short circuit from a headphone plug is unlikely to produce only a flaky left-click; the symptom described points more to an intermittent mechanical or grounding issue. Common hardware causes include a failing microswitch under the left-click, a loose or dirty ribbon connector under the palmrest, a stuck/damaged detection switch inside the 3.5mm jack, or a transient ESD/grounding effect when a metal plug is inserted or removed.

Useful, non-invasive checks:

  • Use a different set of headphones or a plain 3.5mm plug to see whether the problem follows the old headset.
  • Test the touchpad outside the OS by entering BIOS/UEFI setup (common keys: F2/F10/Del) or by booting a Linux live USB. If the left-click misbehaves there, the fault is almost certainly hardware.
  • While testing, press gently around the left-click area and the palmrest; if pressure or flexing changes the symptom, that points toward a loose screw, failing microswitch or ribbon seating issue.
  • Blow the audio jack with compressed air (no metal probes) and inspect the headphone plug for corrosion or bent contacts.

If hardware looks likely and there is comfort with basic disassembly: power down, remove AC and battery, ground oneself, then reseat the touchpad ribbon connector and re-test. If the machine is under warranty or there is reluctance to open it, seek authorized service—replacement of the click mechanism or palm-rest assembly is a common repair. If the problem only appears in Windows after the BIOS/Linux test, run a clean-boot/profile isolation and check Event Viewer for HID errors; an external USB mouse can serve as a stable workaround.

Since , and already covered boot/driver-side ideas, these hardware-focused checks should help pin whether the root cause is a failing switch, loose cable, jack issue, or transient ESD/grounding effect related to the old headphones.

That sounds highly unusual. Have you contacted Sony's tech support for this?

It may be a driver issue. One thing I've found on my netbook running Windows 7 is that if I don't have a component connected to the netbook at boot time, it won't work right if I plug it in after boot time.

Try connecting your headphones to the netbook when it is powered down. Then start the netbook and see if the headphones and left touchpad click work correctly. If they do, then it would seem to be this strange anomaly that I've seen on mine.

I hope this helps -

I think there is a driver compatibility issues and the best way to cure it is to upgrade the drivers.

Sony Vaio systems are soooo funky when dealing with hardware that is not Sony branded, that almost anything can be the cause of this. My advice? Get your money back and purchase a system from Toshiba or someone else but Sony.
