Installation
Before installing, disable
Secure Boot
in the BIOS.
Accessibility
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
.
Wireless
For wireless to work, unblock
rfkill
.
To unblock wlan:
$ rfkill unblock wlan
To unblock
bluetooth
:
$ rfkill unblock bluetooth
Audio
For audio to work, install
Sound Open Firmware
.
The bass speakers do not work by default.
Create
:
/etc/modprobe.d/snd.conf
options snd-sof-intel-hda-common hda_model=alc287-yoga9-bass-spk-pin
In newer kernels, change the above to
/etc/modprobe.d/snd.conf
options snd-sof-intel-hda-generic 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-cm
AUR
. With
battmngr
AUR
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
.

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:
SPMO
FCMO
Mode
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.
