Yung Shen, as per http://www.dell.com/support/home/us/en/19/product- support/product/inspiron-15-5551-laptop/drivers an update to your computer's buggy and outdated BIOS is available (A03). 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, if the problem is still reproducible, and the information above is provided, then please mark this report Status Confirmed. Otherwise, please mark this as Invalid. Thank you for your understanding. ** Tags added: bios-outdated-a03 ** Package changed: linux-lts-vivid (Ubuntu) => linux (Ubuntu) ** Changed in: linux (Ubuntu) Importance: Undecided => Low ** Changed in: linux (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-lts-vivid in Ubuntu. https://bugs.launchpad.net/bugs/1499665 Title: [SynPS/2 Synaptics TouchPad] TouchPad not working after installtion Status in linux package in Ubuntu: Incomplete Status in xorg package in Ubuntu: Confirmed Bug description: During installation touchpad works perfectly, but after trusty(3.19) installed, and restarted, touchpad unable to use anymore.
