manadi, as per http://support.lenovo.com/us/en/products/laptops-and- netbooks/thinkpad-w-series-laptops/thinkpad-w541 an update to your computer's buggy and outdated BIOS is available (2.21). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?
If it doesn't, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report. Once the BIOS is updated, and the information above is provided, then please mark this report Status Confirmed. Thank you for your understanding. ** Tags added: bios-outdated-2.21 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu.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/1437386 Title: Unable to boot LenovoThinkpad W541 Status in linux package in Ubuntu: Incomplete Bug description: I tried to boot my Lenovo Thinkpad W541 using a bootable USB(having Ubuntu 14.04 image). I could see the welcome screen where I can choose to try or install Ubuntu. Choosing either one causes a freeze. Initial boot screen shows the following error (which maybe the reason?): "mmc0 unknown controller version(3), You may experience problems" I cannot run "apport-collect" since this problem stops me from booting. --- ApportVersion: 2.12.5-0ubuntu2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: ubuntu 2803 F.... pulseaudio /dev/snd/controlC0: ubuntu 2803 F.... pulseaudio CasperVersion: 1.336ubuntu1 DistroRelease: Ubuntu 13.10 LiveMediaBuild: Ubuntu 13.10 "Saucy Salamander" - Release amd64 (20131016.1) MachineType: LENOVO 20EGS01600 MarkForUpload: True Package: linux (not installed) ProcFB: 0 inteldrmfb ProcKernelCmdLine: file=/cdrom/preseed/username.seed boot=casper initrd=/casper/initrd.lz quiet splash -- maybe-ubiquity ProcVersionSignature: Ubuntu 3.11.0-12.19-generic 3.11.3 RelatedPackageVersions: linux-restricted-modules-3.11.0-12-generic N/A linux-backports-modules-3.11.0-12-generic N/A linux-firmware 1.116 Tags: saucy Uname: Linux 3.11.0-12-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo dmi.bios.date: 02/26/2015 dmi.bios.vendor: LENOVO dmi.bios.version: GNET72WW (2.20 ) dmi.board.asset.tag: Not Available dmi.board.name: 20EGS01600 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: Not Available dmi.modalias: dmi:bvnLENOVO:bvrGNET72WW(2.20):bd02/26/2015:svnLENOVO:pn20EGS01600:pvrThinkPadW541:rvnLENOVO:rn20EGS01600:rvrNotDefined:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.name: 20EGS01600 dmi.product.version: ThinkPad W541 dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1437386/+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
