I want to apologize in advance if this is in the wrong section, I'm new to the forum. If it is I would kindly request that a mod move it to the appropriate area.
Long story short I dropped a textbook on my keyboard and it completely obliterated my fn key (it's the one to the left in the picture I've attached). The computer is reading the fn key as being pressed down, and this has caused problems because my arrow keys have functions attached to them (volume up and down/brightness up and down).
Yes, I know that Google is my friend. I tried KeyMapper and Mapkeyboard which supposedly can remap/disable keys. Neither program had the fn key as a mappable key. Mucking around in my BIOS looking for the ability to disable the fn key was also fruitless
I tried SharpKeys, and while it looked more promising I wasn't able to discern what the fn key would be in the registry lingo (if it was even there at all). I think this might be my best bet, but obviously I can't press the fn key to figure out what it's registry code is.
Obviously a physical repair is in order, but money is tight right now and with finals around the corner it's just not feasible. I need a functioning keyboard, and typing papers without arrow keys is supremely annoying.
If anyone can offer any help, it'd be greatly appreciated.
Thanks.
