Tim Chen, as per
http://www.dell.com/support/troubleshooting/us/en/19/Product/inspiron-14-amd-m4040
an update is available for your BIOS (A05). 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.
