While suspended the screen is in fact off, and the relevant LEDs enter a "breath" mode, indicating a suspended state, but there is an audible mechanical "tick" sound coming from the bottom, where I suppose the fan is located, and the laptop produces heat (gets hot if it's in a closed environment like my backpack) At first I thought it was a "lid closed" issue, but after further experimentation turns out that it's not a lid issue, but rather a suspension issue; suspending from the power button has the same result I could not reproduce this behaviour on Windows (I am dual booting, Windows Fastboot is off btw); suspending works properly; tested it, no "tick" sound, no heat. P.S. for what it's worth, my Thinkpad x13 Gen 1 on ubuntu 22, same kernel version on AMD Ryzen Pro 7 4750U, has no issues with suspend. Attaching system specs below. Please let me know what other info I need to provide Thanks. --- ProblemType: Bug ApportVersion: 2.28.1-0ubuntu3.1 Architecture: amd64 CRDA: N/A CasperMD5CheckResult: pass CurrentDesktop: ubuntu:GNOME DistroRelease: Ubuntu 24.04 InstallationDate: Installed on 2024-09-29 (3 days ago) InstallationMedia: Ubuntu 24.04.1 LTS "Noble Numbat" - Release amd64 (20240827.1) MachineType: LENOVO 21MCS06F00 Package: linux (not installed) ProcEnviron: LANG=en_US.UTF-8 PATH=(custom, no user) SHELL=/bin/bash TERM=xterm-256color XDG_RUNTIME_DIR=<set> ProcFB: 0 amdgpudrmfb ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-6.8.0-45-generic root=/dev/mapper/ubuntu--vg-ubuntu--lv ro quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 6.8.0-45.45-generic 6.8.12 RelatedPackageVersions: linux-restricted-modules-6.8.0-45-generic N/A linux-backports-modules-6.8.0-45-generic N/A linux-firmware 20240318.git3b128b60-0ubuntu2.4 Tags: noble wayland-session Uname: Linux 6.8.0-45-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sudo users _MarkForUpload: True dmi.bios.date: 08/07/2024 dmi.bios.release: 1.8 dmi.bios.vendor: LENOVO dmi.bios.version: R2LET27W (1.08 ) dmi.board.asset.tag: Not Available dmi.board.name: 21MCS06F00 dmi.board.vendor: LENOVO dmi.board.version: SDK0T76530 WIN dmi.chassis.asset.tag: No Asset Tag dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: None dmi.ec.firmware.release: 1.4 dmi.modalias: dmi:bvnLENOVO:bvrR2LET27W(1.08):bd08/07/2024:br1.8:efr1.4:svnLENOVO:pn21MCS06F00:pvrThinkPadT14Gen5:rvnLENOVO:rn21MCS06F00:rvrSDK0T76530WIN:cvnLENOVO:ct10:cvrNone:skuLENOVO_MT_21MC_BU_Think_FM_ThinkPadT14Gen5: dmi.product.family: ThinkPad T14 Gen 5 dmi.product.name: 21MCS06F00 dmi.product.sku: LENOVO_MT_21MC_BU_Think_FM_ThinkPad T14 Gen 5 dmi.product.version: ThinkPad T14 Gen 5 dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2083454/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
