It is very strange because you have no PS2 trackpad representation in ACPI. Yet the driver is still loading. I don't get it, but it is probably the source of your trouble.

Post both your native DSDT (fresh extract) and patched DSDT.

Follow both DSDT's, original and patched.

And again, thanks for your support, Rehabman.

There a quite a few PS2 trackpad objects in your DSDT, but none active.

You'll need to use ACPIDebug to determine what is going on in each _STA method.

For example, devices PS2M (generic PS2 trackpad), SYN0 (synaptics).

The results seem dependent on variables DA18 and TPVD.
 
Could this be an issue on my dsdt?

What you think is better:
- Extract my dsdt again
- Make use of ACPIDebug to debug system calls

Think the problem could be on my acpi/dsdt table.

No idea. You could boot with native DSDT and see if there is any difference.

ACPIDebug is a good tool when review of the DSDT code doesn't turn anything obvious.
 
I'm thinking about patch my dsdt again.

Since I have all info about my laptop (chipset, audio, video, cpu etc), what patches should I apply to it, to keep it perfect and without unnecessary patches?
 
I'll extract it again using patchmatic and will patch it following your tutorial.

Thanks.
