[Bug 1912935] Re: battery drain while notebook off / shutdown
@kaihengfeng, the first test with unloading a limited amount of modules (due to rmmod -f limitations) did not result in 0% battery drain. So the next step would be a modified kernel that allows unloading all modules (see #56). Do you maybe have another suggestion of how to find out which module needs to be removed just before shutdown to avoid the battery drain? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1912935 Title: battery drain while notebook off / shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1912935/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1912935] Re: battery drain while notebook off / shutdown
Did not manage to do a first test with all modules unloaded (many are in use), so made a simple script that runs rmmod on all loaded modules, logs the result and then shuts down the laptop. Running unmodified 5.15.0-33-generic Ubuntu kernel at the moment. To be able to use "rmmod -f" I would have to rebuild the kernel with CONFIG_MODULE_FORCE_UNLOAD=Y, but maybe the modules that can be unloaded now will already help find the culprit. Battery drain is usually around 2% per day, so will report back in a couple of days. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1912935 Title: battery drain while notebook off / shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1912935/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hello Kai-Heng, hello Martien, thank you for your efforts. I am here on Manjaro affected by this bug. My hardware is the same as in the description of this bug. I compared (a) standard Manjaro 5.17.9 kernel, (b) same with Kei-Heng’s 0001-PCI-Detach-PM-domain-on-shutdown.patch (#50), and (c) with the original patch published on lore.kernel.org (see #22 of this thread). Battery state was recorded after 10 – 11h shutdown from /sys/class/power_supply/BAT0/capacity. Power consumption during startup was neglected. Extrapolated 24h-power drain was for (a, standard) 14.4%, (b, 0001...patch) 14.9%, and (c original patch) 2,4%.

Somehow it did make a difference a couple of times, but unfortunately not always: the last time I thought I had it configured the right way finally by adding the 'acpi_osi=!' part, and it did work after the first reboot and shutdown. But then after I read your last comment #48 I noticed again the drain. So now I am left with the only thing that works at the moment: the HP laptop power reset, where I shutdown the laptop as usual, and then when it is off I unplug everything and hold the power button for 30 seconds.

I ran one more test (twice) since my last comment. Following the resolution of a StackExchange answer I found [1], I can confirm that when I run Manjaro on Linux 4.14.248-1, even with sleep/suspend, I don't face any heavy overnight battery drain. == Test 4: 1. Boot (and wait a few seconds after signing in). 2. Open some applications and use them a bit (firefox, yakuake, konsole, nvim, node) - about 1 minute. 3. Close all applications. 4. Close the lid of my laptop to trigger sleep/suspend (I'm sure that closing the lid does indeed cause the OS to sleep - confirmed by double checking the corresponding setting from the system settings UI as well as from the journalctl logs). 5. Wait for around 10-20 seconds. 6. Open lid and sign back in. 7. Wait 10 seconds. 8. shutdown and wait for 5 seconds after all of the lights have gone out before closing the lid. Results: - 2% drain (58% -> 56%) in exactly 4 hours powered off. - 2% drain (100% -> 98%) in exactly 17 hours and 33 minutes powered off (yes, that's 17 (seventeen) hours - not a typo). Conclusion: - We now have a "last stable" version and a "known broken" version, it's possible for one to begin bisecting the kernel version that introduced this issue. - I understand that this bug report is for Linux/Ubuntu, but seeing as to how it's now clear that this is due to the Linux Kernel itself and not the distro, my data should still provide some degree of value here despite it being collected on a Linux/Manjaro. == [1] https://unix.stackexchange.com/questions/409774/manjaro-on-hp- laptop-battery-drain-while-powered-off -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1912935 Title: battery drain while notebook off / shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1912935/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1912935] Re: battery drain while notebook off / shutdown
I've collected some more data and it seems to suggest that maybe suspend/sleep has something to do with this? = Test 1: 1. Boot (and wait a few seconds after signing in). 2. Suspend/Sleep (using the "sleep" button from Manjaro/KDE's GUI). 3. Wait 20 seconds. 4. Wake from sleep. 5. Wait 20 seconds again. 6. Poweroff (and not the time and percentage just before doing so). 7. Wait a few more seconds before closing the lid. Result: 12% drain (100% -> 88%) in exactly 2 hours powered off. Note: All of the data points from my previous comment were done with Sleep/Suspend being one of the steps of my test workflow. In this new version of the test, I test for a shorter period of time and have not opened any applications during the test workflow. = Test 2: 1. Boot (and wait a few seconds after signing in). 2. Open some applications and use them a bit (Firefox, VS Code, Yakuake, FZF) - about 1 or 2 minutes. 3. Close all applications. 4. Poweroff (and not the time and percentage just before doing so). This time I forgot to wait a few seconds after powering off before closing the lid (but I *did* at least wait till all the lights turned off) Results: 2% drain (88% -> 86%) in exactly 6 hours powered off. 1% drain (32% -> 31%) in exactly 9 hours powered off. Results when I don't open any applications: 1% drain (44% -> 43%) in exactly 2 hours powered off (run 1). So it seems like opening applications doesn't have anything to do with this (as expected). = Test 3: (no formally described steps this time) Results when I force powered off from my bootloader menu (currently, that's rEFInd): 1% drain (47% -> 46%) in exactly 2 hours powered off. Results when I shutdown from my BIOS/UEFI menu (interrupt the boot process and go straight to the UEFI menu): 0% drain (100% -> 100%) in exactly 6 hours and 20 minutes powered off. = Conclusion: I'm pretty sure that there's no BIOS v/s Bootloader issue here and that the difference in the rate of battery drain is negligible. I'm also pretty sure that as long as I don't let my laptop sleep/suspend on Manjaro (running Linux 5.10 or Linux 5.13) it's fine. Could this help in identifying the source of the bug? Could someone else please conduct similar experiments so that we can cross-validate the results?

The notebook is seemingly powered off and looses 10% battery charge over night. I tried 5.4, 5.10 and 5.11 kernels. Hopefully an ACPI-specific patch will arrive at lore.kernel.org soon. The patch for the preliminary fix seems to consist of one line of code only and is contained in the thread Kai-Heng cited in #22. May be it is time for a bit of private enterprise. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1912935 Title: battery drain while notebook off / shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1912935/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@kaihengfeng Your kernel is installed. At a first 10 hour test, it stopped on the same percentage. With the previous kernel impossible. I will check again tomorrow! But I have no wifi or other network connection, the module is not building (same on the mainline kernel).
