Thinkpad L570 Touchpad

2018-02-01, 17:01 PM

I have seen this issue on a couple of L570's fresh from the factory.

 

The message comes up straight after boot and on this particular one the Touchpad stops working intermittently, I've made sure the bios and all drivers are up to date but still get the message.

 

There does not seem to be any way to remove the touchpad software.

 

There is an uninstaller in the Apoint2k folder but it says it can't run under this OS. The OS is Windows 10 64-bit.

 

 

Anyone else seeing this?

 

 

Solved! See the solution

Dear customer,

I'm assuming you are a corporate customer since you saw multiple L570 systems.

In order to confirm the customer's experience and environment properly, I'd like customer to clarify below items.

 1. Do you mean "fresh from the factory" as the system you received from Lenovo factory with Lenovo standard Windows preload, or your company specific preload ?

2. During the Out Of Box process, have you activated Wireless LAN or attached Ethernet cable on the target systems?

3. Have you opened Devie Manager and tried to uninstall or rollback the driver?

 

thank you for your cooperation.

Dear customer,

Sorry for no response for a long time.

In order to remove this unexpected error message, can you try to operate as below?

  1. Click "Abort" to close the pop up message
  2. Open Task manager by right mouse button on the task bar
  3. Go to "Service" tab and find "ApHidMonitorService"
  4. Stop the "ApHidMonitorService" service by clicking right mouse button
  5. Open Device Manager and uninstall ThinkPad UltraNav driver
  6. Restart the system and open Device Manager to confirm the device is still exist or not
  7. if you still found the driver, uninstall the driver again.
