IBM/Lenovo

From Wikipedia:

ThinkPad is a line of business-oriented laptop computers and tablets designed, developed and marketed by Lenovo, and formerly IBM. The line was originally sold by IBM until 2005, when a part of the company's business was acquired by Lenovo.

ThinkPad battery control

This article or section is a candidate for merging with tp_smapi.

Notes: tpacpi-bat is already covered in tp_smapi. tp_smapi#Supported laptops also already covers supported ThinkPads. (tp_smapi is already mentioned in the parent page at Laptop#See also, so it may be unnecessary to mention it here again to avoid duplication. (Discuss in Talk:Laptop/Lenovo#Removal of 1.1 battery control section))

For newer ThinkPads it is possible to set a stop and resume charge threshold with tpacpi-bat. A user-submitted list of ThinkPads compatible with tpacpi-bat is available here. For many older, pre Ivy Bridge, ThinkPads tp_smapi is available.https://linrunner.de/tlp/faq/battery.html#which-external-kernel-module-do-i-need-for-my-thinkpad

Note: Since kernel 4.17, newer Thinkpads can leverage the natacpi API (part of the thinkpad_acpi kernel module) via TLP. As a result, tpacpi-bat is not needed anymore (see also here). Moreover, on some new models, tpacpi-bat is not able to persist the threshold settings while the laptop is powered off (i.e., if laptop is on AC when powered off, the battery will ignore settings set via tpacpi-bat).

UltraBay devices

Ultrabay was IBM's, now Lenovo's name for the swappable bay. It is possible to hotswap a ultrabay by just releasing the UltraBay eject lever or pressing hotkeys such as Fn+F9. Consult ThinkWiki's page for detail.

Battery conservation mode

Battery Conservation Mode is a feature that limits battery charging to 55-60% of its capacity to improve battery life, being most useful when the laptop tends to run on external power much of the time. This works on many Lenovo laptops like IdeaPad and Thinkbook series. To check if your laptop is supported, try to set the battery conservation mode in the Vantage app on Windows. If it works on Windows, it can be enabled or disabled on Linux in the following manner:

  • First make sure the ideapad_laptop kernel module is loaded, with the lsmod command.
  • If it is, run the following command as root to enable Battery Conservation Mode:
    # echo 1 > /sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/conservation_mode
  • A 0 will in turn disable the feature.
Note:
  • Both the presence and implementation of this feature vary by model. Particularly, the name of the folder VPC2004:00 could differ.
  • If the above does not work on your laptop, you can try a different method described here, which may require some (further) trial and error.

If you use GNOME you can install the Ideapad extension to get an easy toggle (don't forget to configure sudo for it as well).

Special buttons

Some special buttons are not supported by X server due to keycode number limit, and may also not be recognized on Wayland. Listed below are the two most common ones, but others can be encountered.

Key combination Scancode Keycode
Fn+F11 0x49 374 KEY_KEYBOARD
Fn+F12 0x45 364 KEY_FAVORITES

You can remap unsupported keys so that they can be detected and mapped in X by creating the following configuration:

/etc/udev/hwdb.d/90-thinkpad-keyboard.hwdb
evdev:name:ThinkPad Extra Buttons:dmi:bvn*:bvr*:bd*:svnLENOVO*:pn*
 KEYBOARD_KEY_45=prog1
 KEYBOARD_KEY_49=prog2
Note: prog1 and prog2 map to KEY_PROG1 and KEY_PROG2 in /usr/include/linux/input-event-codes.h. You can use any key code with a defined value less than 255. The keycode hwdb expects is the lowercased text following KEY_ in the above input event codes header file. eg: KEY_COFFEE would be coffee.

Then follow the steps at Map scancodes to keycodes#Using udev.

BIOS/Firmware update

Lenovo provides support for firmware and BIOS updates via fwupd for some of their devices (ThinkSeries). For other devices Lenovo distributes updates solely as Windows installers. To install these updates without having to install Windows on the machine, you may try the following steps.

Warning: The following instructions can permanently damage your device. Continue at your own risk!

These steps were tested on a Lenovo Yoga 9 14ITL5 (Phoenix BIOS) but should be applicable to other devices as well.

To determine your current BIOS and firmware versions use dmidecode:

# dmidecode --type bios

When performing BIOS updates do not skip intermediary versions! If you are currently on version 1.1 and there are updates to versions 1.2 and 1.4, apply first the update to 1.2 and then the one to 1.4.

To update your BIOS/firmware:

  1. Download the Firmware/BIOS update for your device from the Lenovo Support page
  2. If your installer is compressed into an archive unpack it until you are left with the .exe file
  3. Use innoextract to extract the artifacts from the .exe file
  4. Follow Windows PE to create a bootable USB stick and use the directory with the extracted artifacts as overlay
  5. Connect your device to the external power supply
  6. Reboot into the Windows PE image
  7. Change directory to X:
  8. Run the installer: install.bat (for BIOS) or MEUpdate.CMD (for Intel ME Firmware)

The Lenovo UEFI BIOS update process clears EFI boot entries, and automatically recreates only those applicable to a Windows installation. If you use GRUB, for example, you will likely need to at a minimum add an EFI boot list entry for GRUB, and move it up in the boot priority in the BIOS. Alternatively, a new entry is automatically recreated as part of the GRUB installation process.

If you can boot into an EFI Shell (such as the one provided with an Arch live image), you can re-add a GRUB entry by examining your existing config:

# bcfg boot dump

then selecting the appropriate root file system, and navigate to the GRUB EFI image path, e.g.:

# fs0:
# cd \EFI\GRUB

If your pre-configured EFI entries stop at for example 4, you can add a 5th entry pointing to GRUB with:

# bcfg boot add 5 grubx64.efi "GRUB"

See Unified Extensible Firmware Interface#bcfg for additional details pertaining to using EFI Shell for boot configuration.

Advanced UEFI Options

Warning: DO NOT change any options without understanding the consequences or you may risk permanent damage to your device and potentially void your warranty.

Some IdeaPad and Legion models have some of the more advanced UEFI options locked. It may be useful to unlock them. There are a few known methods that may unlock the advanced options.

Button combination

  • Turn off OneKeyBattery mode in BIOS setup, if it is enabled, and save the BIOS settings.
  • Power down the laptop.
  • Type, with the laptop powered off: F1 1 Q A Z F2 2 W S X F3 3 E D C F4 4 R F V F5 5 T G B F6 6 Y H N.

If you notice the pattern, it is just going down the column from F1 to the letter in the last keyboard row, from F1 to F6. (You may need to replace some keys accordingly if you got a QWERTZ layout or similar alternative layouts).

  • Boot the laptop with F2 pressed to get into BIOS as usual.

EFI variable

On some pre-2022 models, you can create an EFI variable, 6ACCE65D-DA35-4B39-B64B-5ED927A7DC7E-cE! and set it to 1 to enable the advanced options. The userspace efivar can be used to create this variable:

# echo 1 > param
# efivar --name '6ACCE65D-DA35-4B39-B64B-5ED927A7DC7E-cE!' --write --datafile=param
# rm param

Patch EFI modules at runtime

The currently unmaintained tool SmokelessRuntimeEFIPatcher can be used to patch/inject at runtime. There are several patches provided here: https://github.com/SmokelessCPUv2/SREP-Community-Patches

For example

  • Download or build the SmokelessRuntimeEFIPatcher EFI binary, then store the EFI on the ESP, e.g. /boot/efi/efi/srep/SREP.efi
  • Find a suitable patch for your firmware in SREP-Community-Patches, save the patch as SREP_Config.cfg in the top-level directory of the ESP, e.g. /boot/efi/SREP_Config.cfg.
  • Create a UEFI variable for executing SREP EFI binary.
  • Select the SREP boot entry in the UEFI boot menu to run the UEFI setup utilities with the monkeypatched firmware at runtime.

Enable CPPC

To use the amd_pstate driver, CPPC must be enabled, see CPU frequency scaling#Scaling drivers for details on how to enable CPPC.

Troubleshooting

The factual accuracy of this article or section is disputed.

Reason: Lots of vague or unproven bugs/workarounds, poor writing (Discuss in Talk:Laptop/Lenovo)

Thinkpad E440

To resolve the touchpad not working after waking from suspend, create the following systemd unit:

/etc/systemd/system/touchpad-after-wake-fix.service
[Unit]
Description=Run command on resume
After=suspend.target

[Service]
User=root
Type=simple
ExecStart=/bin/bash -c "rmmod rmi_smbus && modprobe rmi_smbus"

[Install]
WantedBy=suspend.target


And then enable/start touchpad-after-wake-fix.service.

ThinkPad E485

Missing IVRS map in ACPI Table, add amd_iommu=pt ivrs_ioapic[32]=00:14.0 in kernel parameters. In order to get X to work correctly, add iommu=soft in kernel parameters (Linux 4.20 only). On Linux 5.2, add iommu=pt to prevent render artifacts on X. In order to get microsd (SDHCI) working, echo 'options sdhci debug_quirks2="0x8000"' > /etc/modprobe.d/sdhci.conf and change module load order MODULES=(sdhci sdhci_pci) in /etc/mkinitcpio.conf (line 7). Do not forget to run mkinitcpio -p linux afterwards. If WiFi does not work on RTL8822BE adapter models, create a file /etc/modprobe.d/wifi.conf and add the following lines: blacklist rtw_pci
blacklist rtwpci
. Then, install rtw88-dkms-gitAUR and reboot.

ThinkPad E585

To solve all these issues mentioned here easier just install the latest BIOS update from Lenovo support website. Missing IVRS map in ACPI Table, add amd_iommu=pt ivrs_ioapic[32]=00:14.0 in kernel parameters. In order to get X to work correctly, add iommu=soft in kernel parameters (Linux 4.20 only). In order to get microsd (SDHCI) working, echo 'options sdhci debug_quirks2="0x8000"' > /etc/modprobe.d/sdhci.conf and change module load order MODULES=(sdhci sdhci_pci) in /etc/mkinitcpio.conf (line 7). Do not forget to run mkinitcpio -p linux afterwards. Bluetooth does not work until a suspend/resume cycle occurs.

ThinkPad E595

Update the bios, if missing IVRS map in ACPI Table.

Bios update can help if Ethernet is not working.

MicroSD does not work out of the box, see #ThinkPad E585 to fix it.

Wake up from suspend broken on X.Org with kernel >= 5.2; works with kernel >= 5.6

Add acpi_backlight=vendor in kernel parameters to fix systemd warning Failed to start Load/Save Screen Backlight Brightness of backlight:acpi_video0

ThinkPad E15 Gen 2

Resume from hibernate will not work until intel_lpss_pci is added to MODULES() in /etc/mkinitcpio.conf. See Power management/Suspend and hibernate#Suspend/hibernate does not work, or does not work consistently for details.

After recovery from suspend, shortly thereafter, system reboots without user interaction. A workaround is available if you're willing to sacrifice suspend-to-ram for suspend-to-idle. The BIOS has two "Sleep State" options, called "Windows" (suspend-to-idle) and "Linux" (suspend-to-ram), which you can find in at Config -> Power -> Sleep State. If you change the setting to "Windows", this will change the state from suspend-to-ram to suspend-to-idle. You can see this if you run cat /sys/power/mem_sleep before and after the change.

The trackpoint and physical buttons will stop working after resuming from hibernate. Use modprobe -r psmouse followed by modprobe psmouse to get the functionailty back

Fingerprint reader is unsupported. Neither fprintd nor libfprintd-tod will work.

If the Fn keys do not work, to update the BIOS, download the "Bootable CD" of the BIOS Update, and use geteltoritoAUR to extract the .img from the .iso with geteltorito.pl -o bios.img downloaded.iso, then use etcher / mintstickAUR / dd to make a bootable USB. See [2] for details.

ThinkPad T440p

  • ClickPad: the whole trackpad clicks, and disabling the trackpad using older versions of synclient makes the trackpoint essentially unusable. This has been resolved in newer versions of xf86-input-synaptics.
  • Audio:
    • HDMI audio is the default audio output device. Consult the ALSA page for details on changing the default.
    • As the X100e/Mini10, it's possible to mute the headset and speaker outputs separately to the master. Muting the speaker output improves bass output on the headset port.
    • If the system fails to wake from sleep, it can lose sync with the internal audio card and speakers/headphones may fail to work. In this case, put the system to sleep, and wake it again and audio functionality should be restored.
  • The fingerprint sensor is a Validity VFS5011, available in fprint.
  • thinkpad_acpi:
    • To toggle Fn-Lock, press Fn + Esc, this will toggle the LED on the keyboard. While the Fn LED is on all Fn functionalities work as intended out of the box.
    • Controlling the 'glowing I' LED is apparently not possible.
    • fan control does not seem to work.
  • Graphics and Video:
    • With the integrated GPU, xrandr can crash while attaching or detaching displays connected via the dock.
    • The built-in miniDisplayPort will sometimes spew I²C issues into the kernel log.
    • Hardware video acceleration is highly recommended as it performs significantly better than CPU decoding of large media files.
    • The BIOS should not be upgraded past version 1.14, as newer BIOSes cause memory corruption when used with Bumblebee. See Bumblebee GitHub
  • Connectivity:
    • Bluetooth is extremely fragile. The controller works fine most of the time, but can cause the system to wedge totally on sleep/wake cycles, especially if a connection was active at sleep. Disable the controller using bluetoothctl before sleeping.

ThinkPad X260

Panel Self-Refresh (PSR) can cause the screen to randomly freeze every few minutes. This can be fixed by disabling PSR.

See https://reddit.com/r/archlinux/comments/gu0a8a/ for more details.

IdeaPad Y700

The subwoofer needs https://gist.github.com/BXZ/48cd8173807676a1402cf4bc7928c0c0 to get it working.

IdeaPad 3 14IIL05

Touchpad fixed in recent kernels(or is it systemd, i have lost overview)(1-2 months ago or so i think and the date now is: 19.03.2023) so diregard the below if you have updated your system recently

Passing pci=nocrs as kernel parameter fixes the touchpad. Unfortunately this also disabled my wifi(it was seen by iwctl but never presented a station no matter what i did). I see others online also have this problem(various posts on stackexchange etc). I finally managed to fix it by also passing pci=realloc so the full line is:

pci=nocrs pci=realloc

for getting both wifi and touchpad working.

Note: I am using refind as boot manager(holy cow so much more straight-forward and less confusing than grub2) and i seem to recall being unable to boot with pci=realloc using grub2. This could just be me dreaming though so it probably bears testing first.

Everything else works, except the brightness keys -- which sometimes work, and sometimes do not. I have not figured out in which instance they work or not yet. I managed a fix which was to bind ctrl+f11 and ctrl+f12 in KDE to be able to set the brightness(up/down) all the time.

  • UEFI:
    • to be able to disable Secure Boot (necessary for dual boot, not needed for Linux only), you have to switch from "UEFI first" to "UEFI only" (or something like this) in UEFI setup menu; the Secure Boot option appears then on the Security tab
    • after UEFI update having Linux and Windows installed, the Linux bootloader ceased to be the default one, UEFI started to load Windows by default and it was impossible to select the Linux one in the UEFI boot menu and in the UEFI setup - reinstalling the bootloader helped; having no access to a boot media that supports UEFI, a solution might be also replacing the Windows EFI bootloader file with a Linux one temporalily, in order to be able to boot Linux from HDD
    • for the UEFI update, a Windows OS is needed
  • Touchpad:
    • Synaptics - works after installing Synaptics drivers from repo, possible to change behaviour (like reaction for double tap) according to your wish
  • Video:
    • in laptops with dual video card (Intel and ATI) - detects both, Intel is active as a default, not checked if it's possible at all to switch between them

Operation with a HDD caddy

When you install an SSD in the place of the HDD and you want to have your HDD still inside the laptop, it is possible to install it in the place of the optical drive in a special "HDD caddy". The optical drive is of 9 mm height, but a 9,5 mm caddy (ultra slim) fits in the slot. A caddy with a SATA interface is needed. It is difficult to separate the front bezel from the original optical drive (and opening its case does not help, but brings a danger of making a mess in the opening mechanism; the only option is just to pull the bezel using a bit of force, but you risk breaking the latches).

While the HDD installed instead of the optical drive operates flawlessly in Windows, it was not going to work out of the box in Linux, at least in one case. The kernel tries to establish a connection with the disk, but fails to do it (SATA link down entry in /var/log/messages). The solution is to force a 1.5 Gbps transfer speed (instead of 6 Gbps) by adding a libata.force= kernel parameter. See [5] for details.

N200 (3000)

Sound: You may have to append options snd_hda_intel model=lenovo to /etc/modprobe.d/modprobe.conf for sound to work.

S21e-20

Tested with broadcom-wl-dkms 802.11 wireless driver

There is an issue with tpacpi-bat not reporting the right value for the stop threshold. This seems to be related to a buggy BIOS and can not be fixed application wise.

See https://github.com/teleshoes/tpacpi-bat/issues/44
