The mainline kernel resolves the bug. ** Description changed:
I have a lenovo T500 and when booting on battery the Ethernet card does not work. If the laptop is on AC it does. If I plug the AC in after boot the Ethernet card begins to work and remains working even if the AC is removed. Ethernet works if the acpi=off is added to grub. - --- + --- ApportVersion: 2.9.2-0ubuntu5 Architecture: amd64 AudioDevicesInUse: - USER PID ACCESS COMMAND - /dev/snd/controlC0: cprofitt 2009 F.... pulseaudio + USER PID ACCESS COMMAND + /dev/snd/controlC0: cprofitt 2009 F.... pulseaudio DistroRelease: Ubuntu 13.04 HibernationDevice: RESUME=UUID=96605a0a-95c6-4f73-a82b-9b283b3313fe InstallationDate: Installed on 2013-01-13 (82 days ago) InstallationMedia: Ubuntu 13.04 "Raring Ringtail" - Alpha amd64 (20130111) MachineType: LENOVO 2081CTO MarkForUpload: True Package: linux 3.8.0.16.31 PackageArchitecture: amd64 PccardctlIdent: - Socket 0: - no product info available + Socket 0: + no product info available PccardctlStatus: - Socket 0: - no card + Socket 0: + no card ProcEnviron: - TERM=xterm - PATH=(custom, no user) - XDG_RUNTIME_DIR=<set> - LANG=en_US.UTF-8 - SHELL=/bin/bash + TERM=xterm + PATH=(custom, no user) + XDG_RUNTIME_DIR=<set> + LANG=en_US.UTF-8 + SHELL=/bin/bash ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.8.0-15-generic root=UUID=860735d2-7dc0-4a91-a04e-67b5d5bbdc40 ro quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 3.8.0-15.25-generic 3.8.4 RelatedPackageVersions: - linux-restricted-modules-3.8.0-15-generic N/A - linux-backports-modules-3.8.0-15-generic N/A - linux-firmware 1.104 + linux-restricted-modules-3.8.0-15-generic N/A + linux-backports-modules-3.8.0-15-generic N/A + linux-firmware 1.104 Tags: third-party-packages raring Uname: Linux 3.8.0-15-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo vboxusers dmi.bios.date: 12/14/2011 dmi.bios.vendor: LENOVO dmi.bios.version: 6FET92WW (3.22 ) dmi.board.name: 2081CTO dmi.board.vendor: LENOVO dmi.board.version: Not Available dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Not Available dmi.modalias: dmi:bvnLENOVO:bvr6FET92WW(3.22):bd12/14/2011:svnLENOVO:pn2081CTO:pvrThinkPadT500:rvnLENOVO:rn2081CTO:rvrNotAvailable:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.name: 2081CTO dmi.product.version: ThinkPad T500 dmi.sys.vendor: LENOVO ** Tags added: kernel-fixed-upstream ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1165248 Title: Ethernet does not work on battery To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1165248/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
