How to set S3/S4 state for devices on suspend?
Hello!
I have Dell Venue transformer with LUbuntu 18.04 with the kernel 5.1.0-6.4-liquorix-amd64 #1 ZEN SMP PREEMPT liquorix 5.1-4ubuntu1~bionic (2019-06-03) x86_64 x86_64 x86_64 GNU/Linux. I disabled wakeup by all devices except PBTN. In BIOS USB PowerShare is switched off. Nevertheless, after suspending the laptop remains warm. Only three USB controllers (EHC1, EHC2, XHC) do not change the power state: :: Code :: $ cat /proc/acpi/wakeup
$ cat /proc/acpi/wakeup Device S-state Status Sysfs node UAR1 S3 *disabled RP01 S4 *disabled PXSX S4 *disabled RP02 S4 *disabled PXSX S4 *disabled RP03 S4 *disabled pci:0000:00:1c.0 PXSX S4 *disabled pci:0000:01:00.0 RP04 S4 *disabled pci:0000:00:1c.3 PXSX S4 *disabled pci:0000:02:00.0 RP05 S4 *disabled PXSX S4 *disabled RP06 S4 *disabled PXSX S4 *disabled RP07 S4 *disabled PXSX S4 *disabled RP08 S4 *disabled PXSX S4 *disabled GLAN S4 *disabled EHC1 S0 *disabled EHC2 S0 *disabled XHC S0 *disabled pci:0000:00:14.0 HDEF S4 *disabled pci:0000:00:1b.0 TPD4 S4 *disabled PEG0 S4 *disabled PEGP S4 *disabled PEG1 S4 *disabled PEG2 S4 *disabled LID0 S3 *disabled platform:PNP0C0D:00 PBTN S3 *enabled platform:PNP0C0C:00 Testing by non-controlled USB LED toys shows that they are remain on during suspend. Installing laptop-mode-tools is not helpful (possibly, some additional settings are necessary). In my mouse, the LEDs of sensor and buttons are switched off during suspend, but the scroll LED cannot be switched off as well as the power LED on the USB hub. To avoid discharge, I should disconnect USB cable at suspending. How to set the USB controllers to S3 or S4 state? Back to top |
