Cat 5 connected to laptop. Appears as unconnected and won't connect to LAN. Cables have been changed and tried on other connections. All other laptops/computers work on same cable/connections. I have tried disabling, re enabling, deleting the internal network card, updating to no avail. Anyone have any ideas?

Confirm you have the right driver detected for the card... I had a few HP laptops that would detect a AMD network card as intel and would have the same issue.

If that's not it, sounds like the card is bad

You ready to perform surgergy on your laptop? It really sounds like your video card is shot. If it's not hardware, you might have your port disabled. I've heard of certain viruses doing this on occasion.

Good luck!

This has nothing to do with video.

Sounds to me like it's a bad port on the laptop. There are USB ethernet adapters, and PCMCIA ethernet cards you could get to replace it. USB is usually the cheaper route (I think they're about $35).
