Acer Nitro V 16S AI (ANV16S-41) — Linux s2idle suspend/resume issue, but sleep
works on Windows

Hello everyone,

I’m looking for other owners of the Acer Nitro V 16S AI (ANV16S-41) who have
experienced similar suspend/resume problems on Linux, or anyone who can help me
investigate and potentially fix this issue.

System information

* Laptop: Acer Nitro V 16S AI (ANV16S-41)
* Operating system: Linux (distribution and kernel version available upon
request)
* Sleep state: s2idle
* Windows: Sleep and wake work correctly in my testing.

The problem

I’m experiencing a suspend/resume issue on Linux. The laptop does not handle
sleep and wake correctly, and I’m trying to determine the underlying cause.

The most important finding so far is that sleep and wake work correctly on
Windows on the same laptop. This makes me suspect a Linux-specific
compatibility issue involving ACPI, kernel power management, device drivers,
firmware interactions, or the handling of the s2idle sleep state.

I have been investigating this issue and considering possible kernel-level
causes, but I haven’t identified a confirmed root cause yet.

What I’m looking for

I’d appreciate help with any of the following:

* Other users with an Acer Nitro V 16S AI (ANV16S-41) experiencing the same
issue.
* Reports of similar s2idle suspend/resume problems on other recent Acer
laptops.
* Suggestions for relevant kernel parameters, kernel versions to test, or
ACPI-related debugging techniques.
* Advice on collecting useful logs and identifying which device or subsystem
prevents Linux from resuming correctly.
* Anyone familiar with Linux kernel suspend/resume debugging who could help
investigate this issue.

I’m willing to collect additional diagnostic information and test potential
solutions, provided the steps are safe and the changes are reversible.

I would prefer to identify the actual cause rather than blindly apply
workarounds.

Has anyone encountered a similar problem on this model or another recent Acer
laptop? Any pointers, relevant bug reports, or debugging suggestions would be
greatly appreciated.

Thank you!
