## Installation

Before installing, disable Secure Boot in the BIOS. You can access the BIOS by pressing `F2` at the Splash screen. The boot menu can also be accessed by pressing `F12`.

## 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

This article or section is a candidate for merging with Laptop/Lenovo#Lenovo.

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 IdeaPad 3 15alc6 (AMD))

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.
