Tristan Strange, as per http://support.hp.com/us-en/product/HP-ENVY- TouchSmart-15-j100-Notebook-PC-series/5401191/model/7264959/drivers an update to your computer's buggy and outdated BIOS is available (F.65). 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 ** Tags added: bios-outdated-f.65 ** Description changed: - After sending a number of MIDI notes out of my NI AudioKontrol 1 sound - card my system locks up completely and needs to be hard reset. + With my HP ENVY TouchSmart 15-j144na Notebook PC, after sending a number + of MIDI notes out of my NI AudioKontrol 1 sound card my system locks up + completely and needs to be hard reset.
