I am using latest touchpad drivers for my 2764-CTO T400 with Win7 64 bit installed, but after 8 hours of work I have racked up over 6million page faults in process SynTPEnh.exe.
Version of driver: 22.214.171.124 (05May11)
This is latest Lenovo driver I could find. Anyone have this too?

curious to know, where/how did you acquire those page faults? what program did you use ?
Currently the touchpad driver version is at 126.96.36.199 and its available at http://support.lenovo.com
do update it

I am using Windows Task Manager to see page faults by process.
I am now running version 188.8.131.52 of the driver - I had upgraded it right after posting my original comment as I realized a newer one had been recently posted.
I just rebooted the laptop and after only 1:30 hours of uptime, the process SynTPEnh.exe already has over 500,000 page faults.

At 3h 33min uptime on my T400 running 7x86, I get:
SynTPHelper: 20,008 (this increases with usage of TrackPoint/touchpad scrolling)
As far as I can tell, it's no biggie.
Firefox 8 has over 33 million, so I'm pretty sure the value isn't a bad thing.

Any large value of Page Faults is simply a indication of program errors encountered... 8 mill. for FF8 is definitely a sign of an issue. Decent software should not experience these kinds of page faults. While there is no immediate impact, it does contribute to (or rather detract from) overall system performance and stability IMHO.

I must have a different definition of page faults. AFAIK it isn't an error, it's just the demand paging system pulling in a page that wasn't present in RAM (or maybe wasn't mapped into that processes address space - it doesn't imply a disk access, necessarily). Totally normal on a virtual memory/paging system. Particularly if the system doesn't have a lot of RAM, or other programs or system buffering is using a lot of memory pages.
Now, "page fault in non-paged area", that's an error.
