            Bug ID: 213109
           Summary: ideapad-laptop: Regression in 5.12.x for Battery
                    conservation mode
           Product: Drivers
           Version: 2.5
    Kernel Version: 5.12.4
          Hardware: x86-64
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Platform_x86
          Assignee: drivers_platform_x86@kernel-bugs.osdl.org
          Reporter: fouad.fakih@gmail.com
        Regression: Yes

Enabling battery conservation mode no longer works on Linux 5.12.x for Lenovo
Legion 5 15ARH05.

It works with kernel versions 5.11 and 5.10 on Arch Linux.

Modifying `/sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/conservation_mode`
fails with message : `Input/output error`
