Samaneri Vimala, as per http://support.hp.com/us-en/product/HP-15-d000 -Notebook-PC-series/6529963/model/6663727/drivers an update to your computer's buggy and outdated BIOS is available (F.10). 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 ** Tags added: bios-outdated-f.10 ** Attachment removed: "RfKill.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1413443/+attachment/4308417/+files/RfKill.txt ** Summary changed: - Touchpad HP Pavilion not working + [HP 15-d006au Notebook PC] Touchpad not working ** Tags added: regression-update ** Changed in: linux (Ubuntu) Status: Triaged => Incomplete -- 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/1413443 Title: [HP 15-d006au Notebook PC] Touchpad not working Status in linux package in Ubuntu: Incomplete Bug description: Touchpad on HP Pavilion 15-D006AU not detected after the kernel upgrade I'm using Ubuntu 14.10 --- ApportVersion: 2.14.7-0ubuntu8 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: santi 2188 F.... pulseaudio /dev/snd/controlC0: santi 2188 F.... pulseaudio CurrentDesktop: Unity DistroRelease: Ubuntu 14.10 HibernationDevice: RESUME=UUID=89f01e88-cb44-46d4-947a-00b49c706f4f InstallationDate: Installed on 2015-01-19 (2 days ago) InstallationMedia: Ubuntu 14.10 "Utopic Unicorn" - Release amd64 (20141022.1) MachineType: Hewlett-Packard HP 15 Notebook PC Package: linux (not installed) ProcFB: 0 radeondrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.16.0-23-generic.efi.signed root=UUID=a047ce07-afb9-4d4b-bd99-01610ceb6eab ro quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 3.16.0-23.31-generic 3.16.4 RelatedPackageVersions: linux-restricted-modules-3.16.0-23-generic N/A linux-backports-modules-3.16.0-23-generic N/A linux-firmware 1.138 Tags: utopic Uname: Linux 3.16.0-23-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo _MarkForUpload: True dmi.bios.date: 11/13/2013 dmi.bios.vendor: Hewlett-Packard dmi.bios.version: F.07 dmi.board.asset.tag: Base Board Asset Tag dmi.board.name: 2192 dmi.board.vendor: Hewlett-Packard dmi.board.version: 41.18 dmi.chassis.asset.tag: Chassis Asset Tag dmi.chassis.type: 10 dmi.chassis.vendor: Hewlett-Packard dmi.chassis.version: Chassis Version dmi.modalias: dmi:bvnHewlett-Packard:bvrF.07:bd11/13/2013:svnHewlett-Packard:pnHP15NotebookPC:pvr0975100000405F10000620180:rvnHewlett-Packard:rn2192:rvr41.18:cvnHewlett-Packard:ct10:cvrChassisVersion: dmi.product.name: HP 15 Notebook PC dmi.product.version: 0975100000405F10000620180 dmi.sys.vendor: Hewlett-Packard To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1413443/+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
