T470 Trackpoint/Touchpad not working after wake up from Sleep mode

2017-10-25, 22:12 PM

Hi, I put my laptop to sleep mode (AC Adapter on) for 7 hours, then both trackpoint and touchpad stopped working. OS is Windows 10 pro. I updated the UltraNav, the auto-detect system update webpage shows that I am using a T470 (Type 20HD, 20HE) Laptop (ThinkPad), and "No drivers are required to update for your machine". And also I load the setup to default from BIOS (both trackpoint and touchpad are "ON")

 

None of the current solutions I can find on the forum works, so please help me !

something weird comes up.

After I remove and reinstall my keyboard

1. the touchpad starts to work. I reboot for like 10 times, it works for 7-8 times.

2. the trackpoint is still not working. It is greyed out on Mouse Setting.

Hi, I have basically the same problem.

Intermittently after sleep, the laptop will not recognize the touchpad/trackpoint, and requires several (up to 3-4) hard restarts until it finally does recognize them.  Then it works again through several days of sleep/wake cycles.  Occasionally it also transiently does not recognize the keyboard!

My previous T440 also had the same issue.  I even replaced the trackpoint/touchpad on that unit and it did not help.  I can't believe the same problem is happening again!

New T470 with Windows 10 Pro and drivers all up to date, like the other poster.

Any advice would be welcome.

I've the same problem on t460p. I think it's a driver related problem. If i uninstall the UltraNav Driver the touchpad starts working after next reboot, so it runs on the standard PS2 driver. But Windows 10 installs the UltraNav driver again. Trackpoint and trackpoint buttons stop working after next reboot/suspend.

Hi JJ75,

I am giving a possible explanation: please remove the keyboard and take a closer look at if the lock-clip on of your mainboard trackpoint connector is loosened. I think somehow I've broken it a bit so that the wires from the trackpoint cannot be tightly locked within the connector, which caused the malfunction.

 

But I am not sure.

I had the same problem and i found a solution.

The problem with the latest windows update is that windows does not immediately recognize the Synaptic device.

Check Device manager->Mice and other pointing device, you should see "Synaptic Pointing Device". If not, you need to do the following:

1. download the ultranav driver from lenovo website. Install it, but that's not enough. Because for whatever reason, the device .inf file is not installed.

2. Locate where the driver extracts the installation file, usually here: C:\DRIVERS\UltraNav

3. locate the C:\DRIVERS\UltraNav\SynPD.inf file

4. right click on the file and choose "install"

5. it will prompt restart.

Once you restart, it should work, and under device manager->mice and pointing device, you should see the HID-compliant mouse and the Synaptic Pointing Device.

 

My problem was that the synaptic poiinting device never showed up. And one of the HID-compliant mouse is on "synaptic" but has the lagacy 2006 microsoft driver. The driver however cannot be updated for some reason... The trick I described above allows the machine to "see" the synaptic device, and so far, seems to have solved my problem.

 

Good luck.

Thanks, that is useful!  My machine seems to have fixed itself with the BIOS update that appeared at end of November, and now shows the Synaptics device, has been working properly for about 10 days now.  Bizarre that the driver.inf didn't get automatically installed previously.

I tried the steps mentioned above but withour success - used my computer on its dock all day with a USB mouse, took it the dock this evening and no touchpad or trackpoint.  Worked fine last night.

 

Bit stuck now.

 

Update:  Well, that was odd. Rebooted the laptop and the keyboard didn't work either.  Mild panic.  Rebooted again and now everything works fine, including the touchpad and trackpoint.  Phew!

 

I noticed a couple of odd things - I'd disabled fast boot as it was causing issues if the machine was put into sleep off the dock and then restarted when docked.  I found fast boot was enabled again.

 

Second thing is the fingerprint sensor seems much more sensitive - in the past it works first time almost every time.  This evening it's taken several attempts each time.
