This is the Paddy_solver and since you are not able to find the bios upgrade i am giving you a link from where you can download your bios update however before you would do it lemme tell you it can crash your motherboard as well i would say if your computer is working fine you better not do it if your computer administrator has said so please go for it.
Link to download :-http://support.acer-euro.com/drivers/utilities.html#BIOS
when the website would open you have to look in the middle of the page where it says "BIOS UPDATE TOOLS"
NOW BEFORE YOU WOULD INSTALL OR DOWNLOAD ANYTHING PLEASE MAKE SURE YOU SHOULD KNOW THE BIOS INSTALLED ON YOUR LAPTOP FOR THAT YOU HAVE TO ENTER THE BIOS EITHER BY PRESSING "DELETE KEY" OR "F2 KEY " ONCE YOU RESTART THE LAPTOP TRY IT BOTH THE KEYS ONE BY ONE IF YOU ARE NOT ABLE TO GET TO THE BIOS.
AND ONCE YOU WOULD SEE THE BIOS IT WOULD EITHER SAY "AWARD BIOS" OR "PHOENIX BIOS" ONCE YOU KNOW WHICH BIOS YOU HAVE THEN DOWNLOAD THE FILE ACCORDINGLY.
HOPE THIS INFORMATION IS USEFUL FOR YOU IF ANY FURTHER QUREY YOU CAN CONTACT ME AT MY EMAIL IE:-
Thanks and Regads
