I have a problem that I think I have diagnosed...my Sony VAIO is shutting off whenever it changes power states, however this only happens when there is a Linksys network card plugged in. I have 2 different Linksys network cards (different models); both seem to cause this problem. I have no other PC cards in my house though, so before I run out and buy a new NIC, I'd like to ask...do you think it's the PC card slots themselves or the Linksys cards? Any experience?

Thanks...
