Benjamin Morgan, thank you for reporting this and helping make Ubuntu better.
As per http://www.dell.com/support/home/us/en/19/product- support/product/precision-m5510-workstation/drivers?os=biosa an update to your computer's buggy, insecure, and outdated BIOS is available (01.02.13). When you update to this following https://help.ubuntu.com/community/BIOSUpdate how does this improve the situation? 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. Also, you don't have to create a new report. Once the BIOS is updated, if the problem is still reproducible: 1) Please provide the output of the following terminal command (not perform an apport-collect): sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 2) Please make a comment specifically advising on how this improves the situation. 3) Please mark this report Status New. If it's not reproducible, please mark this as Invalid. Thank you for your help. ** Tags added: bios-outdated-01.02.13 ** Summary changed: - Backlight does not resume from suspend/hybernate + Backlight does not resume from suspend ** Description changed: - Using an internal 4k display.
