Touchpad driver causing high CPU usage RRS feed

  • Question

  • Hi,

     

    I have a Y510p and have posted about this on another thread. After upgrading the touchpad driver ( Lenovo elan touchpad Version 17.0.10.12/11.4.26.1) and ,possibly coincidentally Windows 8.1 I noticed a process called "System" in the task manager is eating up 6 to 12 % CPU usage. Opening its file location seems to reveal that its "ntoskrnl" application.

     

    After a system factory reset and many curse words I noticed a peculiar thing. The processor shows high usage only when the mouse is being used. The more the mouse is used the higher the CPU usage (caps at about 12%). I am assuming this is a bug. 

     

    I have removed the driver and tested this and the process no longer used the CPU by that amount. But I lose all my features. Is there any way I can resolve this issue without having to either wait for a newer version of the driver (whih may take a very long time?).

    I have posted about this issue on the lenovo forum as well and am not sure how relevant this might me be here. But in case any one has dealt with such an issue before please help me out.

     

    Thanks

    -Geril

  • Thanks...I have tried this driver before but it gave me some error and did not get installed. I did however figure a way to solve the problem. I uninstalled all touchpad related drivers and software (Lenovo bundles a bunch of them) and then reinstalled the windows 8.0 driver available on the manufacturer website.

    So,this issue was caused by the incompatible driver.
