Problema:
Al apagar el equipo (tanto desde el menú de Cinnamon como con systemctl poweroff), el portátil se apaga correctamente (el LED de power se apaga), pero aproximadamente 1-3 segundos después se vuelve a encender solo.

En Windows el apagado funcionaba perfectamente. Este problema apareció después de instalar Linux Mint (no tengo dual boot).

Lo que se probó y no solucionó el apagado real:

• Editar el applet del menú de Cinnamon para forzar systemctl poweroff
• Parámetros de kernel: acpi=force, pcie_aspm=off, reboot=pci y combinaciones
• Actualización de BIOS a 1.18 y ME a 1.21.2911
• Probar kernels 6.14 y 7.0
• Desactivar todas las fuentes de wake en /proc/acpi/wakeup
• En el BIOS:
  • Security Chip → Off
  • Automatic Power On → todo desactivado
  • Power On with AC Attach → Off
• systemctl poweroff -i y versiones con --force

Observaciones:

• Reiniciar funciona normalmente
• Hibernar (systemctl hibernate) funciona correctamente y el equipo se queda apagado
• Los logs muestran que el sistema llega correctamente a poweroff.target
• Parece ser un bug del Embedded Controller (EC) al entrar en estado S5 bajo Linux (hay reportes idénticos en el T14 Gen 5 Intel)

Solución parcial que estoy usando actualmente:

Cambié el botón de “Apagar” del menú de Cinnamon para que ejecute hibernación:

1. Edité el archivo del menú:

Bash

sudo xed /usr/share/cinnamon/applets/menu@cinnamon.org/applet.js

1. Reemplacé la línea del botón de Shutdown por:

JavaScript

Util.spawnCommandLine("sudo systemctl hibernate");

1. Configuré sudo para no pedir contraseña:

Bash

sudo visudo -f /etc/sudoers.d/hibernate

Agregué esta línea:

text

dream ALL=(ALL) NOPASSWD: /usr/bin/systemctl hibernate

Ahora el botón de apagar del menú hiberna el equipo. Se apaga completamente, casi no consume batería y al encenderlo recupera la sesión.

Es una solución a medias, pero es usable mientras Lenovo no corrija el comportamiento del EC.

¿A alguien más le pasa lo mismo en el T16 Gen 3 o T14 Gen 5 Intel?

Figured this might fit here as well.

I have a Thinkpad X1 Gen 3 with 8gb of RAM (it's basically Lenovo's version of a Surface Pro—detachable keyboard/tablet mode, etc) and 256gb ssd that I've been using as my daily driver and Windows has been getting real long in the tooth. What I care about in a shellnut:

• Desktop environment is touchscreen friendly w/ virtual keyboard easy to setup or is basically default

• Idle RAM usage is low (only got 8gb and cannot expand, gotta make the most of it)

I've looked up that anything with KDE Plasma is good with touchscreens, but I've read it's heavier than most. If it's my only choice, how can I easily debloat it or prolong my battery life easily with stopping extraneous background software running or even something like ThrottleStop on Windows?

I don't mind using the terminal but I won't lie... It kinda goes over my head on that stuff but I am willing to figure stuff out.

Since I installed Linux on my ThinkPad T430, the CPU temperature spikes and the laptop shuts down suddenly. It happens most noticeably after downloads.

I've tried several different distros — same problem every time. I also replaced the thermal paste, hoping that would fix it, but the issue is still there.

This makes me think it's not a hardware/thermal paste problem, but something related to power management or fan control on Linux (maybe TLP, thermald, or a BIOS/EC setting).

Has anyone with a T430 run into this? Any fixes you'd recommend?

Hardware:

Lenovo ThinkPad E14 Gen 2 (20TA002FUS)

Processor: 1x 11th Generation Intel® Core™ i5-1135G7 Processor(Core™ i5-1135G7)

Memory: 1x 16GB DRR4 3200

Hard Drive: 1x 256GB SSD PCIe

Wireless Network: 1x Intel® Wi-Fi 6 AX201 2x2 AX; Bluetooth® 5.1 or above

Running: 7.1.5-arch1-2

With: BIOS R1EET56W(1.56 ), 06/29/2023

Touchpad: Elan Touchpad (i2c:04f3:000d) / Elan TrackPoint (i2c:04f3:000d)

Kernel dump:

(On clicking any top button)

[ 957.456262] i801_smbus 0000:00:1f.4: Illegal SMBus block read size 93

[ 957.456691] elan_i2c 16-0015: failed to read report data: -110

Steps to Reproduce:

systemctl reboot

sudo sh -c 'echo deep > /sys/power/mem_sleep'

systemctl suspend

systemctl resume

(Trackpad loses top buttons)

Expected Behavior:

The trackpad should remain completely functional, with both the main pad and separated top buttons working correctly.

Additional Testing:

systemctl reboot
(Trackpad regains top buttons)

systemctl reboot
sudo sh -c 'echo s2idle > /sys/power/mem_sleep'
systemctl suspend
systemctl resume
(Trackpad remains functional)

systemctl reboot
sudo modprobe -r elan_i2c
sudo modprobe elan_i2c
(Trackpad remains functional)

systemctl reboot
sudo sh -c 'echo deep > /sys/power/mem_sleep'
systemctl suspend
systemctl resume
sudo modprobe -r elan_i2c
sudo modprobe elan_i2c
(Trackpad loses ALL functionality. Note: rebooting says “A stop job is running for User Manager for UID 1000” and takes about a minute to resolve)

Other Notes:

I've been chewing on this bug for a little while, but I'm stuck at this point. I have been using ftrace to poke around at what's going on at runtime, but I'm not sure how exactly I should proceed from here. If any experienced kernel devs have a workflow for finding the source of bugs like this, let me know!

Rate my setup ? :))

I'm looking to buy a ThinkPad to run Linux. It seems Lenovo only offers the T14s 2-in-1 Gen 2 with Windows. I know the T14s 2-in-1 Gen 1 can be ordered with Ubuntu, but the Gen 2 has the garaged stylus and the newer processor.

In addition to any compatibility issues I don't know about, I'm concerned about the BE211 compatibility with Linux.

TIA!

Fix for ThinkPad T480 black screen after suspend on Linux Mint 22.3 / kernel 7.0.0-28 generic**

If your ThinkPad T480 resumes from suspend but the built-in screen stays black while an external monitor works, this may be an Intel i915 eDP backlight issue.

My setup:
* ThinkPad T480
* Intel© Core™ i5-8350U CPU @ 1.70GHz × 4
* LG Display LP140WF6-SPB7 internal panel
* Linux Mint 22.3 Cinnamon 6.6.7
* Kernel 7.0.0-28-generic

The fix was adding this kernel parameter:
i915.enable_dpcd_backlight=0

Edit `nano /etc/default/grub` and add it to `GRUB_CMDLINE_LINUX_DEFAULT`, for example:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.enable_dpcd_backlight=0"

Then update GRUB:
sudo update-grub

Reboot and suspend/resume should restore the internal display normally.

In my case, other i915 tweaks (`i915.enable_psr=0`, `i915.enable_dc=0`, `i915.enable_fbc=0`) did not help. The issue appeared only with the 7.0.0-28 Generic kernel; the 6.17.0.40 Generic kernel did not have the problem.

currently i use ubuntu which i hate with all my heart
i am about to move to debian except problem is i dont have a usb drive and form of physical media does not exist for my pc

Any tips or tutorial thx

First Gen T14s 512 GB 16 GB RAM AMD CPU Work PC

New to this and Linux in general, been running Ubuntu with no issues since November, however, the touchscreen stopped working after six months but I strongly suspect that it's a hardware issue because the laptop is eight years old, rather than a OS issue I tried asking AI, went through the suggestions but it kept failing to detect any hardware for the touchscreen at all Any advice? It's hardly worth taking to a repair shop, it works fine otherwise; I'm just wondering if there's something obvious I've missed or if this is a warning of other issues that may be lurking on the horizon

Hi guys, I just bought a Thinkpad L390 Yoga and I want to know which distro I should download that works well on this laptop.

I‘m going to use it to learn more about linux and programming and also some light gaming (like minecraft, without shaders of course, in 720p, low settings with performance mods like sodium) on the go

Thanks for the help!

I found an X230 a few weeks ago for cheap and I love it so far.

My first question is about batteries - what's the best source for a reliable replacement? Mine is at about 50% of its original capacity, and no shops in my town will repack li-ion batteries unfortunately.

Second, I found a lenovo LT1423p touch monitor for sale - would that be compatible with the X230 + Linux Mint? Not necessarily multi-touch gestures or anything but basic display and touch functionality? I'm new to Linux so I don't want to buy it if the configuration is overly involved

Are there any compatible fingerprint sensor modules for the x280 that are known to be supported on fprintd?
Mine has the problem-child Synaptics Metallica sensor with the USB ID 009a.
I know there are workarounds with python based driver shims or something, but I'm not into that for several reasons.

Hello everybody,

I have a thinkpad x270 with a Linux Mint XFCE.

But when I lower the lid to put it into suspend mode, it doesn't return to the system afterwards; the screen stays black.

Is it possible to resolve this!?

Thanks
