Talk:Lenovo ThinkPad X13 Gen 4 (AMD)

spurious wakeups

My ThinkPad X13 Gen 4 (AMD) often wakes up from suspend by itself when picking it up or when carrying it around in a backpack and it was driving me crazy.

I read through Power management/Wakeup triggers and tried disabling the triggers in /proc/acpi/wakeup one by one. After disabling all of them (I first tried to always leave 1 option enabled, but with the power button it wakes up even if everything is disabled) the spurious wakeups still happen!

With cat /sys/class/wakeup/*/device/power/wakeup I saw that there are still 15 devices "enabled" for waking up the laptop.

After playing around with the laptop closed in suspended mode, I noticed I can wake it up by squeezing the laptop slightly in the area around the trackpad. Only now I noticed that the trackpad can also wake up the laptop by pressing until it clicks or by rapid light tapping.

I disabled the trackpad wakeup like this:

echo "disabled" | sudo tee /sys/devices/platform/AMDI0010:01/i2c-1/i2c-ELAN06C2:00/power/wakeup > /dev/null

And it doesn't seem to wake up from picking up and moving it around. There are still 14 wakeup sources left, not sure if I should disable all of them except the lid and power button.

Does anyone else suffer from this? Any idea what the best way would be to permanently disable the trackpad as a wakeup source? (besides disabling the trackpad completely) Markun (talk) 15:06, 6 May 2024 (UTC)

I now found this problem specifically mentioned here, including a solution: https://wiki.archlinux.org/title/Power_management/Suspend_and_hibernate#Instantaneous_wakeups_from_suspend Markun (talk) 20:44, 6 May 2024 (UTC)

Different Hardware on some machines?

I noticed that the hardware listed here is vastly different from the one in my x13 gen 4.

So could there be multiple revisions with different hardware or is it maybe region dependant? I live in Germany and ordered it over Lenovo. Or maybe the hardware listed in the wiki is simply false, but it would be nice if someone could also show their lsusb output.Softwehr (talk) 17:54, 21 October 2024 (UTC)

@Softwehr You can also compare with hardware probes on linux-hardware.org, e.g. this one. Ordoviz (talk) 07:01, 22 October 2024 (UTC)

Oh Thank you, didnt knew this site. Yeah it seems there are many versions of the X13 Gen4 Softwehr (talk) 13:12, 24 October 2024 (UTC)
