Disable power management for Intel(R) Serial IO I2C Host Controller - A369

Question

Im trying to disable power management on this driver because there is an issue with Dell XPS 7590, when the driver is set to power management enabled, the mousepad fails after a while being on, so I tested disabling the power management of Intel(R) Serial IO I2C Host Controller - A369 and it works fine the problem is that every time I reboot the computer the power management gets enabled so i have to change it manually every single time, which is quite annoying, Dell does not have a solution for this issue.

Hello

Thank you for your question and reaching out.

I can understand you are facing issue to Disable power management on Intel(R) Serial IO I2C Host Controller.

You might be able to apply this provided you can figure out which control class key is connected to Intel(R) Serial IO I2C Host Controller. Samsung suggests this behavior is caused by a driver conflict. There should be tools you can use to backup the current driver, follow the advice, then install the Dell drivers

Alternatively, you can adjust power plan settings as below steps.

Control panel (the old one) -> System and security -> Power settings -> Change settings of the "Balanced" power plan -> Change advanced settings -> PCI Express -> Power saving -> Set both to disabled.
