Recalibrate shutting down when dischare complete rather than beginning full charge #683

Closed john-cabaj closed 1 year ago

john-cabaj commented 1 year ago

[x] I've read and accepted the Bug Reporting Howto [x] I've provided all required tlp-stat outputs via Gist (see below)

Describe the bug

Computer shuts down after tlp recalibrate BATx rather than starting to charge

Expected behavior

My understanding of tlp recalibrate is that it fully discharges, then switches to charging to 100% once complete.

To Reproduce

Steps to reproduce the unexpected behavior:

  1. Does the problem occur on battery or AC or both? AC power, else I can't run tlp recalibrate
  2. Actions to reproduce the behaviour Run tlp recalibrate on Ubuntu 22.04.2, with 5.19 kernel
  3. Shell commands entered and their output tlp recalibrate BAT0
  4. Full output of tlp-stat via https://gist.github.com/ for all matching cases of 1 (not as file attachment, no screenshots)
$ sudo tlp-stat

linrunner commented 1 year ago

First of all: TLP does not have a function that shuts down the system, so I assume it must be something else.

What exactly happens during this "shutdown"?

a. The machine powers off suddenly b. Ubuntu shuts down (with corresponding messages on the console)

Case a. would be a hardware issue.

Case b. could be that Ubuntu does not take the connected charger into account and thinks it has to shut down because of a low charge level. However, this would not be the normal behavior of Ubuntu. On my machines, such a thing has never occurred during recalibration.

At what charge level (percentage) does the phenomenon occur? Does Ubuntu display any messages on the desktop before shutting down?

john-cabaj commented 1 year ago

It was definitely case A. The charge threshold was well below 0% and continued depleting. The mV dropped to around 9000 last I looked at it. Then the machine had a hard shutdown, straight to black screen.

I was using the stock charger with a Thinkpad P14s Gen 2 (AMD). At no point did it come off AC power.

linrunner commented 1 year ago

Your BIOS is up to date, therefore I guess the EC firmware is as well. The only remaining possibility is a hardware issue. Good luck.

linrunner commented 1 year ago

I'll close here. I would be happy if you report whether the assumption hardware problem is confirmed.

john-cabaj commented 1 year ago

I try not to recalibrate too often. My computer otherwise charges fine, and a “manual” recalibration (full discharge, full charge) yielded a higher “energy_full” value. So all things considered, I was able to recalibrate. I just didn’t expect the computer to shut down halfway through.

linrunner commented 1 year ago

With the charger connected, the ThinkPad must not power off under any circumstances during recalibration. My own P14s Gen 2 AMD does not exhibit this behavior.

john-cabaj commented 1 year ago

Could be the kernel. I’m in between 5.15 (no built-in calibration support without additional modules) and 5.19 (built-in calibration support). I’ll give it another shoot soon.

@linrunner I have experienced the same issue in my L14 Gen2. It's tlp-stat is as follows:

+++ Recommendations
* Install smartmontools for disk drive health info

I never had to recalibrate my battery and because I almost always keep my laptop plugged in I had set START as 40 and STOP at 50 sacrificing runtime for battery health.

Usually, with 50% if I had to disconnect the charger(lets say for a meeting or a break) it would still run on battery for ~45 mins to an hour.

But recently( in past week) I noticed that it didn't even give me 15 mins of backup on battery at 50%.

So I thought why not simply fullcharge the system once? So I did that, I ran sudo tlp fullcharge BAT0 and it charged the system to 100% and then I disconnected it from AC power, then too it gave me ~20-25 mins which is unusually low.

I tried the sudo tlp fullcharge BAT0 again but this time I actually forgot that I had put it on fullcharge and did NOT disconnect the charger. At the end of my workday some 3-4 hours later I disconnected the charger and lo and behold, it gives me full ~4 hours on battery doing the same things I did in previous runs(mostly wrote code, some internet browsing). Which led me to believe that the actual battery is alright but there is some issue in percentages.

Tried to recalibrate, faced the same issue as @john-cabaj of laptop hard shutting down when it nears to almost depleted during the forced discharge while the ac charger was still plugged in.

Currently tlp-stat shows energy_full = 6990 but I know for a fact that that aint the case because if I remove the thresholds and charge it tlp-stat stops reporting the increase in energy after energy_now reaches 6980(99.9% of energy_full) but if I remove the charger right then it doesn't decrease at all for a few minutes and then starts decreasing, telling me that the battery IS CHARGING to above 6990 mWh but it's not being reported to the OS for some reason.

I HAD INSTALLED acpi-call-dkms on my first time install because at that time I was on kernel <5.15, could it be causing issues with the newer kernels? Will uninstalling that help? Is it even safe to uninstall in the first place?

I will try @john-cabaj method of manually "calibrating" the battery but is there a way to reset the battery controller firmware so that it can reset the energy_full count? I tried uninstalling TLP but that didn't even revert the thresholds so I am assuming it's not that easy

linrunner commented 11 months ago

To reset the EC (embedded controller), shutdown the machine, then actuate the emergency reset hole at the bottom with a paper clip.

That's the only advice I can give you. Yours is a hardware issue which is offtopic here. Better ask at Lenovo forums.
