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
.
GPU switching & External Monitors
Installing optimus-manager
On models with an AMD CPU, after installing Arch with the proprietary NVIDIA driver on Xorg (Wayland is not currently tested), any external monitors over HDMI will most likely not work out of the box. In fact, the NVIDIA dedicated GPU will most likely not work straight away. To fix this, install optimus-managerAUR.
After this, you can check your current GPU mode (integrated
/nvidia
/hybrid
) with
# optimus-manager --status
To change your GPU mode temporarily, you can use
# optimus-manager --switch mode
Permanently setting the default GPU mode
To change it permanently you can set the Kernel parameter optimus-manager.startup=mode
where mode
is integrated
, nvidia
, hybrid
(i.e. use both) or auto
(i.e. use integrated when on battery and NVIDIA when on AC power).
Power management
Install acpi_call (or acpi_call-lts for LTS kernel, acpi_call-dkms for other kernels) and load the kernel module:
# modprobe acpi_call
System Performance Mode
There are 3 modes available: Intelligent Cooling, Extreme Performance and Battery Saving. To switch between them, press Fn+Q
on the IdeaPad's internal keyboard.
To view the currently activated System Performance Mode:
# echo '\_SB.PCI0.LPC0.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
).
The value of the bit corresponds to the following System Performance Modes:
SPMO | Mode |
---|---|
0x0 | Intelligent Cooling |
0x1 | Extreme Performance |
0x2 | Battery Saving |
Rapid Charge
Turn on Rapid Charge:
# echo '\_SB.PCI0.LPC0.EC0.VPC0.SBMC 0x07' > /proc/acpi/call > /dev/null
Turn off Rapid Charge:
# echo '\_SB.PCI0.LPC0.EC0.VPC0.SBMC 0x08' > /proc/acpi/call > /dev/null
Get the status of Rapid Charge:
# echo '\_SB.PCI0.LPC0.EC0.QCHO' > /proc/acpi/call > /dev/null # cat /proc/acpi/call; printf '\n'
where 0x0
stands for off and 0x1
stands for on.
Battery Conservation
Similarly to the #Rapid Charge, make sure you have set up acpi_call.
Turn on:
# echo '\_SB.PCI0.LPC0.EC0.VPC0.SBMC 0x03' > /proc/acpi/call
Turn off:
# echo '\_SB.PCI0.LPC0.EC0.VPC0.SBMC 0x05' > /proc/acpi/call
To verify your setting:
# echo '\_SB.PCI0.LPC0.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:
First make sure the ideapad_laptop
kernel module is loaded with the lsmod
command.
If it is, run the following command as root to enable Battery Conservation Mode:
# echo 1 > /sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/conservation_mode
A 0 will in turn disable the feature.
