Alright, here is the dmesg output for the rc1+ kernel. It still says power state D0 instead of D3 (Hope I didn't mess up anything this time):
[ 65.241409] i801_smbus 0000:00:1f.4: PCI PM: Suspend power state: D0 I did a quick test (about 30 minutes) on battery consumption yesterday, which also resulted in about 1.3% drain per hour. I will try to do a more serious test, but I don't know yet when I'll get to that. ** Attachment added: "5.9.0-rc1+_dmesg.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1886920/+attachment/5406435/+files/5.9.0-rc1+_dmesg.log -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1886920 Title: Battery drain during sleep. System suspended before kernel suspends all tasks. Lenovo ThinkPad T460 Status in linux package in Ubuntu: Confirmed Bug description: The same as https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1825636. kaihengfeng closed that one "Because there's no response from the original bug reporter." and asked to file a report for all devices affected, so here I am, duplicating the report. On Ubuntu MATE 18.04, as well as after the update to 20.04, the battery drains about 1,25% per hour of sleep (if I just close the lid). $ cat /sys/power/mem_sleep s2idle [deep] tlp was initially installed on my machine. However, this behaviour also occurs if I $ sudo apt purge tlp acpi-call-dkms && sudo reboot now also, it occurs when booting from a freshly made MATE 20.04 live usb stick, so TLP shouldn't be the culprit. All the log files look in all relevant aspects similar to what was reported in the old report. I'm happy to provide log files from my machine, if any are necessary. --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu27.3 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: richard 1511 F.... pulseaudio CasperMD5CheckResult: skip CurrentDesktop: MATE DistroRelease: Ubuntu 20.04 InstallationDate: Installed on 2018-07-12 (735 days ago) InstallationMedia: Ubuntu-MATE 18.04 LTS "Bionic Beaver" - Release amd64 (20180426) Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 003: ID 04f2:b52c Chicony Electronics Co., Ltd Integrated Camera Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Lsusb-t: /: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/6p, 5000M /: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/12p, 480M |__ Port 10: Dev 3, If 0, Class=Video, Driver=uvcvideo, 480M |__ Port 10: Dev 3, If 1, Class=Video, Driver=uvcvideo, 480M MachineType: LENOVO 20FMS03600 Package: linux (not installed) ProcFB: 0 i915drmfb ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-5.4.0-40-generic root=/dev/mapper/ubuntu--mate--vg-root ro quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 5.4.0-40.44-generic 5.4.44 RelatedPackageVersions: linux-restricted-modules-5.4.0-40-generic N/A linux-backports-modules-5.4.0-40-generic N/A linux-firmware 1.187.1 Tags: focal Uname: Linux 5.4.0-40-generic x86_64 UpgradeStatus: Upgraded to focal on 2020-05-22 (55 days ago) UserGroups: adm cdrom dialout dip docker lpadmin plugdev sambashare sudo tty uucp _MarkForUpload: True dmi.bios.date: 09/21/2018 dmi.bios.vendor: LENOVO dmi.bios.version: R06ET64W (1.38 ) dmi.board.asset.tag: Not Available dmi.board.name: 20FMS03600 dmi.board.vendor: LENOVO dmi.board.version: Not Defined dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: None dmi.modalias: dmi:bvnLENOVO:bvrR06ET64W(1.38):bd09/21/2018:svnLENOVO:pn20FMS03600:pvrThinkPadT460:rvnLENOVO:rn20FMS03600:rvrNotDefined:cvnLENOVO:ct10:cvrNone: dmi.product.family: ThinkPad T460 dmi.product.name: 20FMS03600 dmi.product.sku: LENOVO_MT_20FM_BU_Think_FM_ThinkPad T460 dmi.product.version: ThinkPad T460 dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1886920/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
