Touchpad driver A0E9 induces high CPU usage , best disabled

Hello

Ever since I purchased my Inspiron 7706 I am facing this: from day one, I could hear the fan blowing air and the unit would always be warm. This is not good when you use a device for hours in any case.

Looking into it, i find out that overwall CPU usage from win11 taskmgr is 15%, on a machine doing nothing. I ended up pinpointing the device inducing the useless CPU load, it is the touchpad.

I use 99% of the time a wireless keyboard so I end up disabling the touchpad and the CPU usage goes down to 1%.

I opened a ticket with support, got closed with 'works as designed' , which in my view reads little respect for designers, and of course users. Who wants to accept a 14% CPU load for monitoring an idle touchpad I do not use. The 'fix' that I was given was to lower the CPU capability , hence heats less hence fan noise reduces hence problem solved. I find several instances of end users encounterin the same issue, same fix is given.

**not good**

Needless to say, Intel says this must be a driver issue, Dell Update says driver is uptodate, and MSUpdate also.

 ==>> Is anyone able to give me a hint of how to make this work ? 15% usage for monitoring a touchpad, not a good design in my view. A big waste, I am trying not to get started on the environmental issues beyond my own (noise, heat, dust, electricity bills)

thank you
