Okay...
Well the Bios update was definitely NOT a good thing to do. My right arrow is also not responding.
Itook the laptop apart, searching for a switch or jumper on the motherboard to get back to the old BIOS... if anyone has a dump of the original version, please pass it to me, thanks

Also, while I was at it, I switched the minipci card and added the Atheros chip I bought. Well.. After setting up drivers in win xp, I was able to see my AP but no chance of getting connected... Don't really know waht to do anymore...
If any of you has an idea...
