You can disable iio_sensor_proxy service and reboot. Then look at value of /sys/bus/iio/devices/iio:device*/buffer/enable They all should be 0.

"in_accel_sampling_frequency from 10 to 10", may be you mean something. You have two other devices also.

These settings directly go to firmware and this part of code is not touched from a long time. Did you update BIOS recently?

I don't think you need a patch. Enable iio-sensor-proxy again. You probably want to change hysteresis. This will decide how much change in sample data before data is sent to user. OR need to reduce sampling frequency. Most probably this is accel_3d, which in your case /sys/bus/iio/devices/iio:device3. Recheck with the "name" attribute. Try adjusting in_accel_hysteresis to some higher value and read back if this is accepted by the sensor. For example #echo 0.10 > in_accel_hysteresis Also try to reduce in_accel_sampling_frequency. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1719795 Title: Dell 7140 avarage power consumption in idle increased by 1.3-1.5 times due to events by INT3432 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1719795/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

As the problem can also be reproduced on 4.9.3, remove the regression flag for now. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1719795 Title: Dell 7140 avarage power consumption in idle increased by 1.3-1.5 times due to events by INT3432 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1719795/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thanks for advice! I'll try to do so, as soon as it will be possible. (There is some issues with hardware I usually use for building kernels.)

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.14 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

[Bug 1719795] [NEW] Dell 7140 avarage power consumption in idle increased by 1.3-1.5 times due to events by INT3432
Public bug reported: On Dell Venue 11 Pro 7140 average power consumption in idle increased by 1.3-1.5 times due to events coming from INT343A.

But with Linux 4.9.46-4.9.51, Linux 4.10.0-4.10.17, Linux 4.12.0rc1-4.13.3 - around 300 wakeups per second on average, due to events coming from INT3432:00.
