Touchpad freezes on new T410

[JameZ]

Hi bodsham,

I've just moved the comment from amitoza88 as he is using a T410 and not an EDGE.

The Trackpad issue for the EDGE is still currently ongoing and the thread is still active as well. The placeholder I've placed on the thread is for amitoza88 FYI if he find his comment missing.

The TrackPad for T410 and the EDGE uses different version of Synaptics drivers. Also the hanging of the Synaptics driver is obvious when doing a zoom in and zoom out on the T410 / T510 / X201 / T400

1. Machine Brand  T410
2. Machine Type Model: 2516CTO
3. Operating System Win 7 Pro 64bit
4. Bios version: latest via update S/W.
   
5. How long has the machine been turned on before the issue started to happen? There is no pattern that I can see.
   
6. What were you doing or what programs were running before the issue happened? Using firefox primarily
   
7. How you temporarily fix it? By system reboot? Or turn system to sleep and wake up later? Log out.

Hi All,

Kindly try to do a "Roll-Back" for the driver as a temporary workaround till engineering has provided an updated version of the driver in order to fix this issue.

1. Click Start
2. Click Run
3. Type devmgmt.msc
4. Select "Mice and other Pointing Device"
5. Double click on "ThinkPad UltraNav Pointing Device"
6. Select Driver tab
7. Click "Roll Back Driver"
8. Once the "Roll back" has been completed, reboot your machine.

**Please take note that this TouchPad workaround issue only applies to the following ThinkPad machine as they share the same drivers**

For those who can't roll back to the previous version of the driver. Do uninstall the 15.0.24.0 and download the older ones via the following link.

UltraNav for Win 7 64bit / Vista 64bit / XP 64bit - (Do scroll down page for previous versions of UltraNav drivers)

UltraNav for Win 7 32bit / Vista 32bit / XP 32bit - (Do scroll down page for previous versions of UltraNav drivers)

• Additional comments which you think might help:  Downgrading to 15.0.18.0 seems to have "fixed it." Also, should I copy my posts from the other thread to this one?

• Are you able to recreate the issue on demand? Aside from what I mentioned in the other thread, no.

How do I deal with it when it fails? ending the unresponsive task (C:\Program Files\Synaptics\SynTP\SynTPEnh.exe which takes one cpu [25% of my i5] during this unresponsive state ) ] in task manager lets me move the mouse again, but i no longer get multitouch, and I just need to start that program again to regain that functionality (and get the ultranav icon back).

I have the Same issue on T510 / Windows Server 2008 R2 / i-620/ 8 gb Ram.

The Cpu utilization was 25 % when the problem occur.

I uninstalled the lenovo driver for ultranav and installed the driver from synaptic.

Hi guys, Probably it will be helpful. I noticed that the issue happens during two-finger scrolling in firefox. So obviously it's related to multitouch and firefox. I played with different touchpad setting for multitouch gestures and disabling pinch zoom solved the issue.

Hi all,

My thinkpad t410 come with the lastest UltraNav driver therefore I can't rollback the driver. My temporary solution is installing driver from Synaptics. However, my trackpoint can't scroll. OMG. What should I do now? Thank you all!

[kevinf]

for some reason this issue just popped up on my x201 as well. never happened before until now. hope a solution can be found soon. i did the rollback driver trick and it seemed to have fixed the problem for now.

[thangln]

Can someone upload the old driver of UltraNav please? It must be older than 15.0.24.0. Now I must use driver from Synaptics but the TrackPoint can't scroll . Please help me, thank you!
