Bug 2014261

power-profiles-daemon isn't where the lap detection is made. It's made in the firmware, and power-profiles-daemon or the kernel have no control over how it's done.
At least the version of power-profiles-daemon in F35 won't change the profile when the lap is detected, just show a message in powerprofilesctl or the Power panel.

Your best bet for getting this problem looked at would be to file a bug at https://bugzilla.kernel.org/enter_bug.cgi?product=Drivers under "Platform_x86" as a component, and mentioning "thinkpad_acpi" in the summary.
Mark, Hans, is it correct to say that's still the preferred way to report firmware bugs?

I have a sneaking suspicion that @armin.warda might be SOL on this one.
The laptop sensor setting is just reporting the status of the laptop sensor - I don't think FW particularly gets involved in the degress the platform is set at.

I've created an internal ticket to confirm with the firmware/hardware team (for my reference LO-1393). Nag me if I don't update by end of next week.

For issues like this - I don't really mind where the original bug comes from. If we had an external facing Lenovo ticket system that would be nice...but we don't.

Is there any specific reason this bug is restricted to the Fedora contrib private group?

Sorry, I have no idea why this bug is in the fedora_contrib_private group, and I don't know how I can remove the group from the bug. Any idea? A.

There is a groups list on the right of the comments, active groups on the list have a [x] next to them to remove them, if all groups are removed then the bug becomes public.

I've removed the fedora_contrib_private group now.

Oh, I just notice this is under "Advanced fields" so you need to show those first.

Thanks, Hans, for removing the "fedora_contrib_private" group from this bug report.

Yes, I saw this under the "advanced fields", but for me it showed no [x] next to the group name, thus I was not able to remove it. I was able to add and remove another group, e.g. "security", but not the "fedora_contrib_private" group.

regards, Armin.

I got an update on this:

---	
If user doesn't move system for 270 sec, then lapmode will be undetected as "cql" flag will be disabled as per our implementation. I don't know whether the machine is really stable or not. But if the machine is very stable, CQL should be disabled after 270 sec.  So, this looks to me as unexpected behavior .
---

Armin - are you seeing the lapmode sensor still set after 270s?
I sort of tested this: With a X1C9 I triggered the lapmode sensor, propped it up on a roll of packing tape (classy I know) and waited - and the sensor cleared

Mark

Yes, Mark, I still see this. 

"Lap detected: performance mode temporarily unavailable. Move the device to a stable surface to restore" is reported by Gnome Settings > Power > Power Mode. But now, after I rebased to f35 Silverblue with Gnome 41, the Power Mode remains in "Performance" and is not switched to "Balanced", like when I was still on f34 Silverblue with Gnome 40.

awarda@fedora:~$ powerprofilesctl 
* performance:
    Driver:     platform_profile
    Degraded:   yes (lap-detected)

  balanced:
    Driver:     platform_profile

  power-saver:
    Driver:     platform_profile

The message is also shown when I switch to "Balanced":

awarda@fedora:~$ powerprofilesctl 
  performance:
    Driver:     platform_profile
    Degraded:   yes (lap-detected)

* balanced:
    Driver:     platform_profile

  power-saver:
    Driver:     platform_profile

The ThinkPad is on a very solid, rigid stand, very stable, not moving or shaking. I would guess the body of the ThinkPad is at an angle of 30-45 degrees tilted to me, while the lid with the display is almost vertical.

Could it be that this is neither a SW or FW issue, but simply that the acceleration sensor HW of my ThinkPad is defective?

Armin.

> Could it be that this is neither a SW or FW issue, but simply that the acceleration sensor HW of my ThinkPad is defective?

I'm wondering that too - but that should be easily proven by putting it on a desk flat for 5 mins.

Just to rule out it being a Gnome bug - can you do:
   cat /sys/devices/platform/thinkpad_acpi/dytc_lapmode
As this returns the sensor status

I'll check with the FW team if there's any other ideas of what might be causing it.

Thanks
Mark

I took the ThinkPad from the tilted laptop stand and put it flat on the table. Then I observed /sys/devices/platform/thinkpad_acpi/dytc_lapmode and powerprofilesctl with the "watch -d" command

After ~6min30s the /sys/devices/platform/thinkpad_acpi/dytc_lapmode changed from 1 to 0 and "Degraded" changed from "yes (lap-detected)" to "no":

awarda@fedora:~$ powerprofilesctl 
* performance:
    Driver:     platform_profile
    Degraded:   no

  balanced:
    Driver:     platform_profile

  power-saver:
    Driver:     platform_profile

What does this tell us regarding the acceleration sensor HW, the FW or SW?

Best regards
Armin.

Hi Armin,

Well that confirms the sensor and the FW are working I'm afraid.

When the system is on it's stand are you interacting with it (keyboard/mouse/touchscreen) or is it just sitting there? Is it possible to leave it on the stand completely untouched so we're sure that it's not small movements that are triggering it?

I'll see if there are any other suggestions from the FW team.

Thanks
Mark

Yes, the Thinkpad is completely solid, untouched on the stand. 

I am not typing on the ThinkPad, I use a wireless keyboard and mouse. The table is not shaking or vibrating. The only physical interaction with the ThinkPad is touching the fingerprint sensor (unlock the screen and sudo) or yubikey (2FA), but that happens only maybe 3-5x per day. 

Armin.
