Hi! I have successfully installed EOS on Lenovo Ideapad 5 Pro 16ACH6, KDE, thanks!
To check power management I just ejected power supply plug, closed lid and went to sleep. In the morning I have got completely discharged laptop. All PM KDE settings are kept in default state.
Please, point me where to dig in to resolve the issue. My old laptop (Honor MagicBook 16 pro running Manjaro) takes about 7-10% during night. It would be great to get something similar.
sounds like youre just suspending and not hibernating. Im not positive hibernation is enabled on default as there are many systems that have serious issues with it. Manjaro may enable hibernation while EOS may not.
This arch wiki article should help with looking into setting up hibernation
if you recently installed EOS itll be using dracut which will require tweaking the instructions. If you have any questions setting it up i can try to help.
This is a recent guide on enabling hibernation in EOS with dracut, you will have to change the grub commands though as you likely are using systemd-boot
instead of grub commands you would simply add resume=UUID=<UUID of your swap partition> to /etc/kernel/cmdline (this is equivalent to GRUB_CMDLINE_LINUX_DEFAULT) then easiest way to regenerate the loader file is to reinstall the kernel with
sudo pacman -Syu linux linux-headers
I unfortunately cant test this as my system doesnt recover from hibernating. Follow this guide with the tweaks for systemd-boot i mentioned instead of grub and add a swap partition and youll be able to hibernate
I’m not sure I want a hibernation as far as old laptop hasn’t got swap partition also, but on suspend it is much more humble on power consuming.
The thing is, power consumption graph (I mean KDE Info Center) doesn’t change steep noticeably on lid closing.
At the moment I’m testing power consumption with blacklisted nouveau driver (I haven’t installed proprietary NVIDIA driver and, in fact, I don’t need equipped RTX 3050 at all, as far as don’t paly games). Is there a possibility to explicitly turn RTX off at all? BIOS seems to lack this option.
