I wanted to run battery recalibration on new p14s.
I got:
Setting temporary charge thresholds for BAT0:
stop = 100
start = 96
Initiating discharge of battery BAT0 ...............
Error: discharge BAT0 malfunction -- check your hardware (battery, charger).

What happens here is that TLP times out after 15 seconds because your ThinkPad did not start discharging the battery. This is probably a malfunction of the embedded controller (EC). This also seems strange to me:
/sys/class/power_supply/BAT0/power_now = 51117 [mW]Is the battery actually charged or discharged with 50 W(!) here? Seems unlikely to me.
My 1st try would be to reset the EC: shut down the system then press the emergency reset hole (button) on the bottom of the ThinkPad with a paper clip. I also recommend updating the BIOS and the EC to the latest version (using fwupdmgr).

What surprises me, however, is that you're trying to recalibrate a battery that is obviously not worn out. It still has the full nominal capacity:
/sys/class/power_supply/BAT0/energy_full_design = 52570 [mWh]
/sys/class/power_supply/BAT0/energy_full = 52570 [mWh]Why do you do that?

I tried with EC reset, and it didn't work. (I kept button pressed down about 3 seconds.)
I have the latest bios. Updated from 1.11 to 1.13 with iso downloaded from Lenovo website.
As for the reason question. I have a new laptop and wanted to check if everything is working correctly. Tlp is one of those things.

In article here :
https://www.phoronix.com/review/thinkpad-p14s-gen4/6
There is an information that p14s doesn't support ACPI Platform Profiles in current bios version.
Could it be related?

I tried it on a T14 Gen 4 AMD yesterday. Did not work either. Lenovo seems to have changed something in the BIOS. The ACPI call used in the kernel for force-discharge works unchanged with all ThinkPad series since 2011, but apparently no longer with Gen 4. Unfortunately said ACPI call is undocumented/not supported by Lenovo. Don't expect a solution or workaround anytime soon.

Unlikely. Completely different functionality.

I tried it on a T14 Gen 4 Intel yesterday. Did not work either. Lenovo seems to have changed something in the BIOS.

That is very bad news.
Thank you for the information.

Bad news indeed. But we still only have a sample of 2.
By the way, I got that mixed up: the T14 was an AMD, your P14s is Intel AMD too.
EDIT: 21K50003GE is AMD
