Fn+L does nothing
/sys/kernel/debug/legion directory does not exist
/sys/class/leds/platform\:\:ylogo/ directory does not exist

Log file: fwts.log

According to lenovo support forums, controlling the LED light is not possible. But fan control using Fn+Q is possible. So if there is a way to control that in software, that would be greatly appreciated.
Fn-Q does not produce a scancode, it was at least not detected by Linux. If you see the images for keyboard replacement, there seems to be a second 4 pin cable that is separate from the 32pin connector. Im not sure what that is for, but maybe that is how it controls the fan?

@sakgoyal This seems to be an older model. Do you know the approximate original year of this model. Nevertheless, I just I added your model/BIOS to the kernel module. Please get the new version, recompile, and reload the kernel module (no need to force anymore).

Then, please test the following features. We have to try a bit to find the correct configuration.

Temperatures and Fan Speeds

Please read the fan speeds and temperatures (see README) and confirm that they are sensible and change accordingly, e.g. when you put load onto the CPU the CPU temp and the fan speeds should increase, but GPU temp should stay roughly the same.

Powermode

We will start by confirming that power mode change work and to get me more debug info. Please change the power mode with Fn+Q and provide the output of the following commands in each mode.

sudo cat /sys/kernel/debug/legion/ecmemoryram | hexdump -C
sudo cat /sys/kernel/debug/legion/ecmemory | hexdump -C
sudo cat /sys/kernel/debug/legion/fancurve

Then please also check if the power mode is read correctly in the OS (see README). Then please check if you can set the power mode with the GUI (see README) and the LED changes accordingly.

Tests the following features with the GUI. Please check that if works or otherwise give precise information about what does not work. Please try to check that reading and writing works with the software.

Please provide the log output from the GUI from the log tab for all the tests.

Fn Lock

Enable fn-lock: A LED might turn on. fn functions now work without pressing Fn
Disable fn-lock: A LED might turn on. fn functions now work only when pressing Fn

Win Key

Enable Win Key: Win Key should work, e.g. open start menu or trigger some other action
Disable Win Key: Win Key has no function anymore

Touchpad

Enable Touchpad: Touchpad works
Disable Touchpad: Touchpad does not work

Battery Conservation

Enabled: charging stops if above 60 % (or 80% depending on model)
Disabled: charging works up to 100%
Note: Sometimes it takes a 10-20 seconds before it takes effect

Rapid Charging

Enabled: Charging is faster; Check this by comparing the time until fully charged displayed in system information or by comparing charging current.
Disabled: Charging is slower
Note: Sometimes it takes a 10-20 seconds before it takes effect .

Charge Output Always On

Enabled: Some USB output is always powered even when laptop is off or sleeping; Test e.g. by trying to charge your phone.
Disabled: USB outputs are off when laptop is off

Display Overdrive

Enabled: display somehow faster
Disabled: display not faster
Just check if checkbox can be checked or not if you cannot verify that it has an effect.

Keyboard Backlight

In order to fix/configure the keyboard backlight and begin with setting fan curves, please put your keyboard backlight to off, medium, or bright. Provide the output of the following commands (in that order) in each backlight state:

sudo cat /sys/kernel/debug/legion/fancurve
sudo dmesg | tail -n 30

Fan curve

First, please give again the output of

sudo cat /sys/kernel/debug/legion/fancurve
sudo dmesg | tail -n 30

Second, please use the GUI and enter custom mode. Do you have a custom mode? Then change the fan curve (currently only the first row for fan 1), write it to hardware, and read it back. Please report back if it works and provide the log output from the GUI and sudo dmesg | tail -n 70.

Its a late 2018 model. It came out sometime around December 2018 +/- a few months.
when I try to compile the kernel module, I get an error. I did make clean as well but it still happened.
I was able to do just the make but when I did sudo make reloadmodule, it failed.
here is the log: log.txt

the thing that confuses me the most is that I am able to turn on conservation mode by changing the value in
/sys/bus/platform/drivers/ideapad_acpi/VPC2004\:00/conservation_mode even though my laptop is clearly not an ideapad model. is this older model just fundamentally different to how it works now?

for more context:

$ cat /sys/kernel/debug/ideapad/status 
Backlight max:  16
Backlight now:  17
BL power value: on (1)
=====================
Radio status: off (0)
Wifi status:  off (0)
BT status:    off (0)
3G status:    off (0)
=====================
Touchpad status: on (1)
Camera status:   off (0)
=====================
GBMD: 0x10060020
HALS: 0x000008d8

$ cat /sys/kernel/debug/ideapad/cfg 
_CFG: 0xfc0df516

Capabilities: bluetooth wifi camera
OSD support: num-lock caps-lock mic-mute touchpad camera
Graphics: Intel and Nvidia

these are the only 2 files in /sys/kernel/debug/ideapad/

sakgoyal · 2023-07-16T23:35:48Z

I spent some time searching through the arch wikis and looking for ideapad instead of legion. and I found this table here:
Ideapad gaming 3

System Performance Mode
There are 3 modes available: Intelligent Cooling, Extreme Performance and Battery Saving. To switch between them, press Fn+Q on the IdeaPad's internal keyboard.

I seem to only have 2 modes. auto, and full fan speed. I dont know if it affects the CPU/GPU performance or not.

This table also makes me believe fan control is not possible. (Fn+Q is not marked)

IdeaPad Flex 5
This link mentions the conservation mode settings I said above.

johnfanv2 · 2023-07-16T23:58:54Z

Thank for the log. Your model has a different embedded controller ID. I changed it. It should load now.

The kernel also loads the ideapad driver becaue the Legion and Ideapad models - at least older ones - share some functionality including the "conservation mode" feature.

Can you change the mode by pressing Fn+Q? Does the a LED change its color?

sakgoyal · 2023-07-17T04:14:39Z

There is no LED for the fan status.
The only LEDs are the caps lock, num lock, power button, big Y logo on the lid, power status led on the right side next to the usb).

The kernel also loads the ideapad driver becaue the Legion and Ideapad models - at least older ones - share some functionality including the "conservation mode" feature.

thats really interesting. I guess it makes sense but thats really confusing.

This time the compile worked. make worked as well as make reloadmodule. dmsg shows that it was loaded, and the /sys/kernel/debug/legion directory also exists now
here are all the logs I recorded.

sudo make reloadmodule > log.txt output: log.txt
sudo dmesg > log2.txt output: log2.txt
(default auto fan) cat /sys/kernel/debug/legion/fancurve > log3.txt output: log3.txt
( max fan speed ) cat /sys/kernel/debug/legion/fancurve > log4.txt output: log4.txt
sudo cat /sys/kernel/debug/legion/ecmemory | hexdump -C > log5.txt output: log5.txt
sudo cat /sys/kernel/debug/legion/ecmemoryram | hexdump -C > log6.txt output: log6.txt

It does read the fan speed values. but since the curve section is missing, it is probably just part of the firmware and impossible to change without a bios update. I distinctly remember there being a bios update to change the fan because the original bios's fan curve was extremely aggressive.

I should also mention the battery has been replaced. the old one didn't hold a charge anymore so I bought a new one off amazon.

Thank you for spending so much time for such an old model. I truly appreciate your help. This is a really nice project.

johnfanv2 · 2023-07-17T06:48:13Z

I updated the code again. Please get the newest version again. It seems like the fancurve is stored at the same places as other old Ideapad laptops. Try to read the fancurve again. Also try to modify it.

sakgoyal · 2023-07-17T21:55:39Z

Fan curve detection works now!!
sudo make reloadmodule > log.txt output: log.txt
sudo dmesg > log2.txt output: log2.txt
sudo cat /sys/kernel/debug/legion/ecmemoryram | hexdump -C > log5.txt output: log5.txt

default auto fan

cat /sys/kernel/debug/legion/fancurve > log3.txt output: log3.txt
sudo cat /sys/kernel/debug/legion/ecmemory | hexdump -C > log4.txt output: log4.txt

max fan speed

cat /sys/kernel/debug/legion/fancurve > log3_2.txt output: log3_2.txt
sudo cat /sys/kernel/debug/legion/ecmemory | hexdump -C > log4_2.txt output: log4_2.txt

edit: looks like the curve doesnt actually change between fan speed modes. detecting the speed works. maybe the hardware only has the default, and the full speed is just in hardware and not software?

johnfanv2 · 2023-07-18T06:31:57Z

Try changing any values (fan speed, temps, ... ) of the fan curve, e.g. by the GUI or from the console (see README). Then give the output of dmesg.
