I have a FW16 running Arch Linux with KDE. Around 18 hours ago, I shut down my laptop at ~60% battery using the “Shut Down” button, and when I turned my computer back on, it was at 2%.
This is really weird, especially as a few weeks ago I did some tests with simply closing the lid rather than shutting down (which I have configured to suspend-and-hibernate since s0idle was horrible) and they only lost ~1% per hour. There’s no reason that hibernation should be using so much less battery than actually shutting down!
As far as I can tell, my computer did indeed properly shut off, as there are no journalctl logs between then and now, and the last few logs before shutdown were the following:
Jun 09 23:31:56 iceland systemd[1]: Reached target System Shutdown.
Jun 09 23:31:56 iceland systemd[1]: Reached target Late Shutdown Services.
Jun 09 23:31:56 iceland systemd[1]: systemd-poweroff.service: Deactivated successfully.
Jun 09 23:31:56 iceland systemd[1]: Finished System Power Off.
Jun 09 23:31:56 iceland systemd[1]: Reached target System Power Off.
Jun 09 23:31:56 iceland systemd[1]: Shutting down.
Jun 09 23:31:56 iceland systemd-shutdown[1]: Syncing filesystems and block devices.
Jun 09 23:31:56 iceland systemd-shutdown[1]: Sending SIGTERM to remaining processes...
Jun 09 23:31:56 iceland systemd-journald[388]: Journal stopped
Perusing my journalctl, I do see a ton of kwin_core: parsing edid failed
errors from kwin_x11 (and many other varied errors) but I can’t presume that those are related.
I did see some old reports that KDE GUI buttons didn’t work, like here, High battery discharge rate during suspend / when lid closed KDE - #3 by Oliver_Jensen, but I’m not sure if it’s related. My journal has entries like Jun 09 23:31:53 iceland dbus-broker-launch[743]: Activation request for 'org.freedesktop.UPower' failed.
but again it seems to have successfully shut off?
I’m really not sure what’s going on here. I have 2 USB-C ports, 3 USB-A ports, a headphone jack, and no graphics card installed as modules. I turned off Bluetooth as well in case that was an issue, but it seems like it wasn’t.
I do notice that after I shut down, the power button still stays on for a bit - is that a sign of something?
Thanks!
