Disable Dell Inspiron 1545 quick set buttons

I happend to own a Dell Inspiron 1545 laptop and accidentally pressed off wi-fi on the quickset button.  This happend during an intense MMO game... I was trying to press 2 on top, but I think I accidentally pressed F2 which is by default the wi-fi toggle. 

At first, I thought the internet connection is down since it was raining hard.  But I tried another device that has wi-fi and was able to connect to the internet.  So, I thought my wi-fi card could be dead or need replacement which is a bad thing since, replacement for a Dell could cost me money.  Good thing Dell also has a diagnose tool for wi-fi and asked me to press the wi-fi button.  It worked, I have now wi-fi connection.

I didn't want that to happend again, and searched for a solution to turn it off, since I rarely use that quick set buttons provided by dell.  In fact, since I'm a developer, I often need to access the function keys; which is a hasle since I have to press 'Fn' (function) button to use it.  Anyway the solution is as follows:

1.  type on the run line in Win 7 "msconfig".
2. select the tab startup
3. look for Quickset checkbox, un-check it
4. click apply button (system will ask you restart to implement changes)

Remember, to save your files before doing this, the system will ask you to restart after making changes.

After the restart, my quick set buttons don't function anymore which is what I wanted.  I can still activate it thru the same process of running 'msconfig'.  I may just need to restart my computer again to activate it.
