Public bug reported:
This is a hardware incompatibility report for a new (2025) notebook
model.
--- UBUNTU BUG REPORTING GUIDELINES ---
1) The release of Ubuntu you are using:
➜ ~ lsb_release -rd
No LSB modules are available.
Description: Ubuntu 24.04.3 LTS
Release: 24.04
2) The version of the package you are using:
➜ ~ apt-cache policy linux-image-generic
linux-image-generic:
Installed: (none)
Candidate: 6.8.0-87.88

3) What you expected to happen:
a) When I resume the laptop from suspend (open the lid), the internal
keyboard should work.
b) When I plug in a P2 headset, I should be able to choose between the
internal mic and the headset mic.
4) What happened instead:
a) When resuming from suspend, the internal keyboard is "dead". It can wake
the system, but cannot type. The touchpad continues to work.
b) When a P2 headset is plugged in, the system forces the input to the
external mic, and the internal mic disappears as an option.
--- DETAILED HARDWARE DOSSIER ---
Hardware: Lenovo IdeaPad Slim 3 15ARP10 (2025 Model, Ryzen)
Kernel Tested:
➜ ~ uname -r
6.14.0-35-generic
This hardware exhibits critical firmware/ACPI bugs on a clean Ubuntu
24.04 installation.
---
ISSUE 1: KEYBOARD SUSPEND BUG (CRITICAL)
---
The internal keyboard (ATKBD) fails to initialize after resuming from S3
Suspend. The keyboard can wake the system but is unresponsive at the login
screen.
Diagnostic Logs (dmesg after resume):
The logs confirm this is a firmware (ACPI) bug and a driver failure to
reconnect to the `serio0` hardware.
[ 0.282857] ACPI BIOS Error (bug): Could not resolve symbol
[\_SB.PCI0.GPP7.DEV0], AE_NOT_FOUND
[ 0.283786] ACPI BIOS Error (bug): Failure creating named object [\_TZ.TZ01],
AE_ALREADY_EXISTS
[ 566.062535] atkbd serio0: Failed to deactivate keyboard on isa0060/serio0
[ 566.477611] atkbd serio0: Failed to enable keyboard on isa0060/serio0
Failed Fixes:
All known kernel parameters have failed to fix the suspend bug:
* `i8042.nopnp`, `i8042.reset`, `atkbd.reset`, `i8042.nomux`, `i8042.dumbkbd`,
`i8042.direct`
---
ISSUE 2: AUDIO JACK BUG (Realtek ALC257)
---
The Realtek ALC257 audio codec is not mapped correctly. The P2 combo jack
(headphone/mic) does not allow user selection. It auto-switches to the external
mic and hides the internal mic.
Failed Fixes:
* All documented `model=` options for the ALC257 (auto, alc257-lenovo,
dell-headset-multi, etc.) in `alsa-base.conf` have failed to correct the map.
---
ADDITIONAL CONTEXT
---
* The `linux-oem-24.04` kernel was also installed, and all bugs persisted. This
confirms the fixes for this new hardware are not yet in the OEM kernel.
* A separate bug (internal keyboard crashing on USB hot-plug) IS successfully
fixed by adding `i8042.nopnp i8042.reset` to GRUB. However, this does not fix
the suspend bug.
CONCLUSION:
This laptop requires a BIOS/UEFI update from Lenovo to correct the ACPI S3
resume behavior and the HDA audio map. Requesting that this bug be tracked and
a fix be pushed via LVFS (fwupdmgr).
