The only thing I know to do about this one is cuss.
Before you do that, though, look inside the PCMCIA slot (I assume your "PCI" cards look more like credit cards, which are actually PCMCIA cards, PCI cards look like a traditional computer card) and see if you see anything that looks funky. You should see two rows of pins. If one pin is missing, bent, or if something's there that doesn't look like it belongs (maybe some foil or a wire stuck on the pins), that could explain your problem. Correcting it will likely involve dissassembly of the computer, which isn't for the faint of heart, as there are many pieces and always at least one elusive screw or impossible-to-dislodge part, not to mention all the short cables that must be plugged in with you holding your mouth right. :deveous: Why can't they make these things easier to work on? Since you say you use Windows ME, I doubt Sony will accept it back for warranty, and would likely charge you a new VAIO's worth to fix it. First, try to fix it yourself, have a friend do so, or take it somewhere like a Computer America and have them work on it. If that don't work, get a new laptop when you run out of profanity. :wink:
