hi sandie, if you select this link first of all and follow the prompts for your serial number and such to make sure your laptop definately falls under the category for the update
Acer Product Advisory
once you download the firmware it installs just like a driver, hopefully anyway, it should on a new model like yours, otherwise you have to write it to cd and reboot and select the cd when given the option from startup.
if it installs just like a driver it should restart by itself, flash the bios, job done.
download it first of all and see what it says, any trouble just come straight back, shouldnt be any bother at all though :)
