The Lenovo Yoga 9i 2022 (14IAP7) is a 2-in-1 convertible laptop powered by Intel's Alder Lake P-Series. It features a 14" touchscreen (IPS or OLED variants).

To ensure you have this version, you can use dmidecode

# dmidecode -s system-version
Yoga 9 14IAP7


Before installing, disable Secure Boot in the BIOS.


This article or section needs expansion.

Reason: Details on the firmware appearance would be nice to know if a blind reader might need assistance to change the settings. (Discuss in Talk:Lenovo Yoga 9i 2022 (14AiPI7))

You can access the BIOS by pressing F2 at the Splash screen. The boot menu can also be accessed by pressing F12.


For wireless to work, unblock rfkill.

To unblock wlan:

$ rfkill unblock wlan

To unblock bluetooth:

$ rfkill unblock bluetooth


For audio to work, install ALSA firmware.

The bass speakers do not work by default. Create:

options snd-sof-intel-hda-common hda_model=alc287-yoga9-bass-spk-pin

Reboot and both the bass speakers and internal microphone should work.

Power management

Battery Conservation Mode is a feature that limits battery charging to 55-60% of its capacity to improve battery life, being most useful when the laptop tends to run on external power much of the time. It can be controlled with ideapad-cmAUR. With battmngrAUR it is possible to control both Battery Conservation and System performance modes.

Kernel method

Set the ideapad_laptop.allow_v4_dytc=1 kernel parameter.

To use without reboot:

# rmmod ideapad_laptop
# modprobe ideapad_laptop allow_v4_dytc=1

Restart power-profiles-daemon.service. Now power-profiles-daemon can do everything below.

Apply this across reboots by setting it permanently.

System performance mode

Notes: This is shared across multiple models and should be put on the generic page instead of duplicated for every model. (Discuss in Talk:Lenovo Yoga 9i 2022 (14AiPI7))

There are 3 modes available: Intelligent Cooling, Extreme Performance and Battery Saving. To toggle it, you need to call some ACPI methods.

First install acpi_call (or acpi_call-lts for LTS kernel, acpi_call-dkms for other kernels) and load the kernel module:

# modprobe acpi_call

Set it to Intelligent Cooling mode:

# echo '\_SB.PC00.LPCB.EC0.VPC0.DYTC 0x000FB001' > /proc/acpi/call

Set it to Extreme Performance mode:

# echo '\_SB.PC00.LPCB.EC0.VPC0.DYTC 0x0012B001' > /proc/acpi/call

Set it to Battery Saving mode:

# echo '\_SB.PC00.LPCB.EC0.VPC0.DYTC 0x0013B001' > /proc/acpi/call

To verify your setting:

# echo '\_SB.PC00.LPCB.EC0.SPMO' > /proc/acpi/call
# cat /proc/acpi/call; printf '\n'

As a result you get the value for the bit SPMO (either 0x0, 0x1 or 0x2).

# echo '\_SB.PC00.LPCB.EC0.SPMO.FCMO' > /proc/acpi/call
# cat /proc/acpi/call; printf '\n'

As a result you get the value for the bit FCMO (either 0x0, 0x1 or 0x2). To interpret the results the following table can be used:

0x0 0x0 Intelligent Cooling
0x1 0x1 Extreme Performance
0x2 0x2 Battery Saving

Rapid charge

Make sure you have set up acpi_call.

Turn on:

# echo '\_SB.PC00.LPCB.EC0.VPC0.SBMC 0x07' > /proc/acpi/call

Turn off:

# echo '\_SB.PC00.LPCB.EC0.VPC0.SBMC 0x08' > /proc/acpi/call

To verify your setting:

# echo '\_SB.PC00.LPCB.EC0.QCHO' > /proc/acpi/call
# cat /proc/acpi/call; printf '\n'

where 0x0 stands for off and 0x1 stands for on.

See the note at the end of #Battery Conservation

Battery conservation

Similarly to the #Rapid Charge, make sure you have set up acpi_call.

Turn on:

# echo '\_SB.PC00.LPCB.EC0.VPC0.SBMC 0x03' > /proc/acpi/call

Turn off:

# echo '\_SB.PC00.LPCB.EC0.VPC0.SBMC 0x05' > /proc/acpi/call

To verify your setting:

# echo '\_SB.PC00.LPCB.EC0.BTSM' > /proc/acpi/call
# cat /proc/acpi/call; printf '\n'

where 0x0 stands for off and 0x1 stands for on.

There is also an alternative way to control the conservation mode of the battery.

Note: The following is not confirmed on this laptop, but it is worth noting that the Lenovo Vantage software for Windows when turning on Battery Conservation mode also turns off #Rapid Charge (if it was on). The same is also valid for the #Rapid Charge: turning it on will bring the battery conservation mode down. The aforementioned acpi call #Battery Conservation will not do this for you, but #Rapid Charge will. So it is possible to get the state where both battery conservation and rapid charge modes are active if you activate #Battery Conservation after #Rapid Charge. You generally do not want this, as Rapid Charging puts more strain on the battery than regular charging, defeating the purpose of Battery Conservation Mode.
