Do not install the below firmware on any system other than the 4780/4080 or it WILL ruin it!
This is at your own risk so if you're not confident in doing this, nobody is forcing you =)
Make SURE you're plugged into AC and have the battery installed when doing this.
First you need to download the .iso file and save it to your desktop:
Next put a blank CD in your CD burner and open up Nero Express:
Select Disc Image:
In the pop up box 2nd pull down menu select "all files":
Browse to your desktop and double click the "fnctrl.iso" file you have saved there:
Review it and burn it. The burner used here was the DVD-RW/CD-RW drive:
Now reboot your computer with the CD inserted. Right at bootup, push "F2" if you need to jump in the bios and set it to boot from CD if it isn't by default. It's listed under the "boot" tab and you just make sure the CDROM is on top of the list by using "+" after you highlight it. Then go to save and exit.
At this point, the computer should automatically flash itself and come to a screen telling you to remove the CD/Floppy and manually reboot.
Remove the CD and hold the power button down a few secs to shut it down, then reboot.
Now the fn key will work as the ctrl key and the ctrl key will work as the fn key so all that is left to do is swap the keycovers to reflect this:
carefully pull up on the top of the key with your fingernail or something like that to release the top half of the key. Then you can lift it off.
To put it back on, slide the bottom down into place first then snap the top into place.
EDIT
For the 4080, the keyboard is like the 5680 in that the keycaps come off opposite from the 8890 and 47XX:
Carefully pull up on the bottom of the key with your fingernail or something like that to release the bottom half of the key. Then you can lift it off.
