Comment 4 for bug 1439492

Po-Hsu Lin / Anthony Wong, as per http://www.dell.com/support/home/us/en/19/product-support/product/vostro-3546-laptop/drivers an update to your computer's buggy and outdated BIOS is available (A05). 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

Once the BIOS is updated, and the information above is provided, then please mark this report Status Confirmed.

Thank you for your understanding.
