Disable Dell Inspiron 1545 quick set buttons (revised)

Dell Inspiron 1545

I wrote at an earlier blog, a way to disable media quick set buttons, but this does not disable the entire shortcut buttons on the top.  The buttons that usually are function keys are by default for media, battery meter, wifi, brightness, extension monitor or projector, etc.

I thought I already solve the problem, by disabling the Quickset on the msconfig.  But that wasn't the solution, since I again accidentally pressed the wifi on/off key and I was again cut off from the network by accident.

The solution is in the bios of the laptop.  Do the following:

1. Access BIOS upon start-up of the laptop
2. Look for the 'Function Key Behavior' setting in the System Set-up (BIOS) utility.
1. The following are the options in the Function key Behavior settings:
1. Multimedia Key First - This is the default option. Press any media key directly.  For function key, press <Fn> + the required function key.
2. Function Key First - Press any function key directly.  For Multimedia, press <Fn> + the required multimedia key.

Note: Multimedia key first option is active only in the operating system.  During POST, press <F2> or <F12> directly.

Source of this solution is from the dell community (USA).  Here is the link of the forum: http://en.community.dell.com/support-forums/laptop/f/3518/t/19281847.aspx

Problem was solved, I was able to press the function keys directly no more need to press <Fn> key.
