My daugthers HP x360 spectre has a problem when running Linux. When she closes the lid, it suspends, and shortly after it resumes, and then stays on in the bag.

I can do a "systemctl suspend", and it suspends. But if the lid is closed, then it starts again.

I can see this in the syslog

It seems that this causes starts the problem: "ACPI: EC: interrupt unblocked"

So my guess is that it has something to do with ACPI.

  • I have tried to update the BIOS, but it claims to be latest.
  • There is no ACPI settings in the BIOS.
  • I have tried to add these to kernel command line pci=noaer pcie_ports=native.
  • I have even tried to run "systemctl suspend" in crontab, which gave the same behaviour.

Anybody have an idea to what I can try next?

Ubuntu: 21.10

This is a brand new machine. She previously had an older x360 model, which worked fine, but a lot of IO has changed.

With trial and error, I found, that my version of the Spectre x360 2in1 (version of 2022) seems to support only up to the S4 power saving mode with the currently available HP BIOS (since Microsoft seems to push the vendors to implement their own proprietary "Modern Standby"). Since Ubuntu tries higher modes when entering Suspend, it died with the default installation.

To get it working, I limitted Ubuntu to go deeper than S4 (this is already quite good). For this, I added to the GRUB configuration intel_idle.max_cstate=4: My GRUB commandline looks now as follows:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_idle.max_cstate=4"

Call

sudo nano /etc/default/grub

...update the corresponding line, then call

sudo update-grub

...and then reboot. In my case, this helped.

Caution
While poking around, I also tried S1, and this led to the situation, that the CPU still worked but the fans stopped turning. The device almost overheated in standby! Prior to use in production, make sure, there are no such problems with your device and setting.

As a sidenote
I hadn't to disable UEFI and TPM, as stated in many posts concerning Suspend problems with this machine. Both options are active and my machine works also in Dual Boot.
