Bug ID: 221065
Summary: ideapad_acpi: unexpected charge_types spam on Yoga Pro
7 14ASP9
Product: Drivers
Version: 2.5
Hardware: AMD
OS: Linux
Status: NEW
Severity: low
Priority: P3
Component: Platform_x86
Assignee: drivers_platform_x86@kernel-bugs.osdl.org
Reporter: rbitton@linux.com
Regression: No

Hi,

I'm experiencing constant dmesg spam from ideapad_acpi on my Lenovo Yoga Pro 7
14ASP9:

[ 733.997072] ideapad_acpi VPC2004:00: unexpected charge_types: both [Fast]
and [Long_Life] are enabled

This started on 6.19.0 on both my distro's mainline kernel and the vanilla
mainline kernel I compiled. The issue is not present in 6.18. It happens about
every minute starting about a minute after boot regardless of if I'm charging
or not.

Model: Lenovo Yoga Pro 7 14ASP9 (83HN)
CPU: AMD Ryzen AI 9 365
BIOS: PSCN17WW (up to date)

The laptop appears to be reporting both Fast and Long_Life charge modes
simultaneously, which the driver considers unexpected. Functionally everything
works fine, including fast charging, but the log spam is excessive.

Of note:
zsh rbitton@rbitton-linux3 01:46 /sys/class/power_supply/BAT0 > cat
/sys/class/power_supply/BAT*/charge_types
[Fast] Standard Long_Life

All attempts to fix it on my end have failed.Let me know if you need any
additional information; I would be more than willing to test any fixes.

Thanks,
Raphael Bitton
