[Bug 1912935] Re: battery drain while notebook off / shutdown

2021-11-17 Thread Hemanth V. Alluri
Narrowed it down a bit.

4.19.208-1 does not exhibit any battery drain issues when sleeping sometime 
before powering off.
  - 0% in 7 hours (97% -> 97%)
  - 0% in 5 hours (100% -> 100%)

5.4.150-1 does.
  - 54% in 10 hours (91% -> 37%)
  - >34% in 12 hours (34% -> Dead)

Could someone else with this problem double check my results with their
laptop?

[Bug 1912935] Re: battery drain while notebook off / shutdown

2021-11-14 Thread Hemanth V. Alluri
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.

[Bug 1912935] Re: battery drain while notebook off / shutdown

2021-11-13 Thread Hemanth V. Alluri
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? Perhaps someone on Ubuntu or some other
operating system that's *not* Manjaro (just so that we can rule out the
operating system as a variable in this)

Once again, please let me know if I can help by collecting more
data/logs/etc.

Oh, I should mention that I faced the same issue when running Ubuntu
18.04 (DE: XFCE) last year. Sadly, I don't recall which version of the
kernel I was running - the damage to my battery ended up getting so bad
that by the end of the year, my battery lost it's capacity to hold
charge and I had to replace it (got warnings from OEM software on
Windows, as well as on boot - before the bootloader menu loaded).

[Bug 1912935] Re: battery drain while notebook off / shutdown

2021-11-12 Thread Hemanth V. Alluri
Hello. I would just like to mention that I, too, face this same exact
issue. I'm running Manjaro and can confirm that I observe this issue on
both Linux 5.10.70-1 and Linux 5.13.9-2. After a full week of testing I
can confirm that I face this power drain only when gracefully shutting
down from Linux.

Basic hardware specs:
  OS: Manjaro Linux x86_64
  Host: HP Pavilion Laptop 15-cc1xx
  Kernel: 5.10.70-1-MANJARO
  Resolution: 1920x1080
  DE: Plasma 5.22.5
  WM: KWin
  CPU: Intel i7-8550U (8) @ 4.000GHz
  GPU: Intel UHD Graphics 620
  GPU: NVIDIA GeForce 940MX

Bios: InsydeH20 f.36 Rev 5

Some timings I've recorded:
  - 44% drain in 9h20m
  - 36% drain in 6h48m
  - 32% drain in 5h35m

When sifting through the system logs using journalctl I didn't find
anything that stuck out as unusually suspicious. No errors as far as I
can tell - but honestly, I don't know enough about Linux to be 100% sure
so please don't hold me to this. I can attach these logs if needed.

Commands used:
  - journalctl -b -1 -r
  - journalctl /sbin/init -b -1 -r | grep -i shutdown
  - journalctl /sbin/init -b -1 -p err..alert

Like asgard2 I can confirm that I do not have wake-on-lan enabled (my
system doesn't support it in the first place as confirmed by the lack of
an option in my UEFI menu and no indication from ethtool), no usb ports
providing power when shutdown, no noticible power drain when shutting
down from the UEFI menu or from Windows, etc. basically everything they
have reported above.

I'd love to help get this fixed - if I can help out by providing more
data, please let me know.
