Y510p Elan Touchpad doesn't work any more

2016-03-22, 21:15 PM

As it said in the title of the topic my touchpad does not work any more, Does not show in deviece manger any more.

It all starts after Windows 10 doing an update for the older driver of the touchpad. The version that windows installed is Elan 11.5. So the problem was after the instalation of that version the touch pad start to behave strangely like not working for few seconds, lagging , jupming all over. So what i did first is to roll back to the older version from the device manger.The version of the driver after going back was Elan 11.4.64
All goes well until i restart my laptop the touchpad doen't work any more and the keyboard too.
From there i did alot of install uninstall of alots of driver with no luck.
NB: The touchpad does not show in the devices manager all along this install uninstall process
Then i found this method that makes my touch Pad works for 2 hours before it start the problem all over again from the begining.
The methods that manged to make it work was:

      -Uninstall of the driver

      -End all process related to Elantech

      -Delete all forlders related to elantech in the register
      -Delete the folder related to Elantech located in C:/programme/Elantech
      -Doing a clean instalation

But this method doen't work any more, i don't know why and the touchpad does not show in the device manager even as unkown device

My system is: Windows 10 Unilanguage Famille
                         Version 1511  
                         OS version: 10586.164

After some research it shows up  thats my touchpad was under hiden devices in the device manger so it's correcctly detected but it's hiden.
Attached u will find all the screenshot related

Dear Sir

Welcome to Lenovo Community


Would you please try to go back to the previous windows version, if it works so there is no compatibilty between the driver & windows 10 & you must wait any new update for this driver, if its still not working so you should go to the service center maybe you have a hardware issue.


Best Of Luck
