JONNALAGADDA Srinivas, as per http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?os=4063&lc=en&cc=us&dlc=en&sw_lang=&product=5277771#N1570 an update to your BIOS is available (F.24). 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
Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Thank you for your understanding. ** Summary changed: - Screen brightness set to maximum on every boot on HP Pavilion dv6 TR7040x + [HP Pavilion dv6-7040tx Entertainment Notebook PC] Screen brightness set to maximum on every boot ** Changed in: linux (Ubuntu) Importance: Medium => Low ** Description changed: - My laptop is an HP Pavilion dv6 TR7040x.
