T470s touch pad part number (20JS) issues

2020-06-29, 17:49 PM

I have tried searching the the parts listings for the Lenovo T470s but looking for the correct part number for the touchpad.

 

I bought one off ebay and it caused a 'PS/2 mouse not found' POST message and when using the pc caused the right mouse button randomly activated. The orginal works but touch pad is worn.

The original has a sticker with 8SSM10L66712G1SG77B42L7 

 

I have tried touchpads with sticker 

 

8SSM10H41273E1FR58ZJ0A3 CDEA005 0AE 

8SSM10L68183G1SG76S41WL R01

 

These both cause the ps2 mouse error

I have not tested this yet but I did see a solution to a similar problem on the Ideapad is to install the touchpad then under bios 'reset to factory defaults'
