Max Oropeza, as per
http://support.gateway.com/us/en/product/default.aspx?tab=1&modelId=3265
an update is available for your BIOS (1.30). 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
Thank you for your understanding.

on the top right of your screen doesn't appear.
