Hi,
I have just installed Manjaro and I have noticed a great battery consumption. An average of 3 hours in Windows are less than 1 hour in Manjaro. What can I do?
acpi -i
Battery 0: Discharging, 74%, 00:36:45 remaining
Battery 0: design capacity 3650 mAh, last full capacity 774 mAh = 21%
Thanks in advance
Hello @Mirawara 
There is TLP for this use case for the power managment: https://wiki.archlinux.org/index.php/TLP
Install the UI:
pamac install tlpui
and run it as root. It loads the file /etc/tlp.conf and makes it more comfortable to adjuste the powersaving settings. Of course you can also edit the file directly.
Also if you own a thinkpad, then install this:
sudo pamac install linux510-acpi_call
this one is compiled for kernel 5.10
I would also recommend to have a look into the arch wiki:
https://wiki.archlinux.org/index.php/Power_management#Power_saving
Thanks, but nothing has changed 
can you report

Thanks, can I disable nvidia gpu and use uhd graphics?
You can try to turn off the NVIDIA card in BIOS. But I think that a better idea will install non-free drivers and create a file named 80-nvidia-pm.rules in /lib/udev/rules.d/ directory. Edit this file with your favourite text editor and enter there this text:
ACTION==“add”, SUBSYSTEM==“pci”, ATTR{vendor}==“0x10de”, ATTR{class}==“0x0c0330”, ATTR{remove}=“1”
ACTION==“add”, SUBSYSTEM==“pci”, ATTR{vendor}==“0x10de”, ATTR{class}==“0x0c8000”, ATTR{remove}=“1”
ACTION==“add”, SUBSYSTEM==“pci”, ATTR{vendor}==“0x10de”, ATTR{class}==“0x040300”, ATTR{remove}=“1”
ACTION==“bind”, SUBSYSTEM==“pci”, ATTR{vendor}==“0x10de”, ATTR{class}==“0x030000”, TEST==“power/control”, ATTR{power/control}=“auto”
ACTION==“bind”, SUBSYSTEM==“pci”, ATTR{vendor}==“0x10de”, ATTR{class}==“0x030200”, TEST==“power/control”, ATTR{power/control}=“auto”ACTION==“unbind”, SUBSYSTEM==“pci”, ATTR{vendor}==“0x10de”, ATTR{class}==“0x030000”, TEST==“power/control”, ATTR{power/control}=“on”
ACTION==“unbind”, SUBSYSTEM==“pci”, ATTR{vendor}==“0x10de”, ATTR{class}==“0x030200”, TEST==“power/control”, ATTR{power/control}=“on”
Next, you should edit file in /etc/modprobe.d/nvidia.conf and write this text:
options nvidia "NVreg_DynamicPowerManagement=0x02"
Then reboot and everything should be fine.
I have installed optimus-manager-qt where I can switch the GPU’s. With Intel UHD it’s a bit better but still bad. Any other advices?
