If not, 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.
Daniel van Vugt, as per http:// www.dell. com/support/ troubleshooting /us/en/ 19/Product/ optiplex- 990 an update is available for your BIOS (A17). If you update to this, does it change anything?
If not, 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.
Thank you for your understanding.
