Power management
AMD P-State
It is possible to configure the use of the AMD P-State driver instead of ACPI CPUFreq. Add amd_pstate=passive
to the kernel command line.
You can verify the new driver is in use by checking the value of /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver
.
More detailed information through cpupower frequency-info
.
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' > /proc/acpi/call
Turn off:
# echo '\_SB.PCI0.LPC0.EC0.VPC0.SBMC 0x08' > /proc/acpi/call
You can also use batmanagerAUR to control both the System Performance, the Battery Conservation mode and Rapid Charge mode through the CLI.
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' > /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' > /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.
