You should be able to use Fn+Q hotkey to change the performance mode, you can see how power button led will change their color. I believe that for 15IAH7 ACPI call should be

\_SB.PC00.LPCB.EC0._Q13

With ACPI call led will not change the color, but you can verify that mode changed by return value. I will ask you to update the wiki entry with this ACPI call if it works for you

Sorry for the late reply, But could you provide me with the exact command to verify mode as I am a noob and not able to figure it out.
Thanks

Can you try this one (should query current mode):

sudo sh -c "echo '\_SB.PC00.LPCB.EC0.SPMO' > /proc/acpi/call && cat /proc/acpi/call"

Also, I've found the way to change the performance mode with ACPI call:

# Battery Saving 
sudo sh -c "echo '\_SB_.GZFD.WMAA 0 0x2C 1' > /proc/acpi/call && cat /proc/acpi/call"
# Intelligent Cooling
sudo sh -c "echo '\_SB_.GZFD.WMAA 0 0x2C 2' > /proc/acpi/call && cat /proc/acpi/call"
# Extreme Performance
sudo sh -c "echo '\_SB_.GZFD.WMAA 0 0x2C 3' > /proc/acpi/call && cat /proc/acpi/call"

Note: I got this from decompiled DSDT table and this may not work for you.

Take a look at power-profiles-daemon:
 https://linuxconfig.org/how-to-manage-p … n-on-linux

It is not installed in KDE. For setup, look at power and battery after on taskbar (status icon). Edit system tray if you don't see it.

# pacman -S power-profiles-daemon

# systemctl enable --now power-profiles-daemon

$ systemctl status power-profiles-daemon

$ powerprofilesctl list
* performance:
       CpuDriver:   amd_pstate
       Degraded:   no

   balanced:
       CpuDriver:   amd_pstate
       PlatformDriver:         placeholder

   power-saver:
       CpuDriver:   amd_pstate
       PlatformDriver:        placeholder

On our Ideapad, we keep intelligent cooling default in the bios because the fan is noisy on cold boot.

Hope this help,
