Issues
Suspend issues (S3 sleep fix)
Suspending works once the necessary BIOS settings are adjusted.
About issue
By default the laptop comes configured for "Modern Standby", a Windows feature that is similar to modern smartphones deep sleep (allowing the devices to remain connected to the network and pull for information like new emails etc).
This does not work properly on Linux and will manifest as the device immediately exiting stand-by after you try to suspend it. You can also see it based on the power LED on the right hand side, it will be on instead of blinking.
Solution: Enabling S3 sleep on advanced BIOS
- Turn off OneKeyBattery mode in BIOS setup, if it is enabled, and save the BIOS settings, and power down the device.
- Follow the instructions to enter the hidden/advanced BIOS
You will find the "Modern Standby" feature in the AMD PBS menu, about 3/4 of the way down. Change this setting to S3 Enabled, save and exit.
Power management options
AMD P-State
As of Linux kernel 5.17 it is possible to configure the use of the AMD P-State driver instead of ACPI CPUFreq. Add amd_pstate to the MODULES in your mkinitcpio configuration and rebuild the image. Append initcall_blacklist=acpi_cpufreq_init to your kernel boot line and reboot.
You can verify the new driver is in use by checking the value of /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver.
Rapid charge
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
Turn on:
# echo '\_SB.PCI0.LPC0.EC0.VPC0.SBMC 0x07' | tee /proc/acpi/call
Turn off:
# echo '\_SB.PCI0.LPC0.EC0.VPC0.SBMC 0x08' | tee /proc/acpi/call
You can also use ideapad-perf to control both the System Performance and the Battery Conservation mode through the CLI or with the provided tray applet.
Battery conservation mode
This device supports battery conservation mode.
Kernel method
Turn on:
# echo 1 > /sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/conservation_mode
Turn off:
# echo 0 > /sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/conservation_mode
ACPI method
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
Turn on:
# echo '\_SB.PCI0.LPC0.EC0.VPC0.SBMC 0x03' | tee /proc/acpi/call
To verify your setting run the command bellow, you should get 1:
$ cat /sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/conservation_mode
Turn off:
# echo '\_SB.PCI0.LPC0.EC0.VPC0.SBMC 0x05' | tee /proc/acpi/call
To verify your setting run the command bellow, you should get 0:
$ cat /sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/conservation_mode
System performance mode
There are 3 modes available: Intelligent Cooling, Extreme Performance and Battery Saving.
Kernel method
To list available options run the command below:
$ cat /sys/firmware/acpi/platform_profile_choices
low-power balanced performance
Set it to Intelligent Cooling mode:
# echo 'balanced' > /sys/firmware/acpi/platform_profile
Set it to Extreme Performance mode:
# echo 'performance' > /sys/firmware/acpi/platform_profile
Set it to Battery Saving mode:
# echo 'low-power' > /sys/firmware/acpi/platform_profile
ACPI method
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.PCI0.LPC0.EC0.VPC0.DYTC 0x000FB001' | tee /proc/acpi/call
Set it to Extreme Performance mode:
# echo '\_SB.PCI0.LPC0.EC0.VPC0.DYTC 0x0012B001' | tee /proc/acpi/call
Set it to Battery Saving mode:
# echo '\_SB.PCI0.LPC0.EC0.VPC0.DYTC 0x0013B001' | tee /proc/acpi/call
Firmware
fwupd does not officially support this device but it can still be used to apply UEFI firmware updates.[1]
Accessing the BIOS
The BIOS can be accessed by pressing the F2 or F12 key while turning on the device.
A number of advanced BIOS menus are available that allow for significant tweaking of the device. Do not touch these setting unless you know what you are doing.
- Power down the laptop.
- Type, with the laptop powered off:
F1 1 Q A ZF2 2 W S XF3 3 E D CF4 4 R F VF5 5 T G BF6 6 Y H N. - Boot the laptop with
F2pressed to get into BIOS as usual, you will get into the BIOS but with a few options more unlocked.
If you do not get a number of extra menus in the sidebar, you either mistyped the combination or did it too slowly. Power off the device and try again.
