My system:

  • Windows XP, SP3
  • HP 6730b laptop

Here are the symptoms:

  • Neither the orange nor the green LED flash when I insert a network cable. The network cable has been verified as functional with another computer.
  • In Network Connections, the status is "Network cable unplugged" even when the cable is plugged in.
  • When I remove the cable, it claims that it is safe to remove the "Broadcom NetLink (TM) Gigabit Ethernet". (Which is on the motherboard.)
  • The WiFi is still working (thank goodness!)

I suspect this might have been caused by new drivers and support that was automatically installed when someone plugged in a cordless mouse USB adapter and then removed it without requesting Windows XP to deactivate it.

Any help is appreciated!

I would suggest disabling/uninstalling it in Device Manager, then grab (& install) the updated Chipset and USB drivers from the HP website followed by a reboot.

Next troubleshooting would be disabling it in the BIOS or even 'rolling back' the driver to the original HP ones (or even reinstalling them from your HP support CD's)

That would probably be a good approach, but I think the actual hardware has failed. Engineer due today some time so I'll let you know. – Bernhard Hofmann Nov 9 '11 at 14:43
Goodluck! Let us know the outcome! :) – HaydnWVN Nov 9 '11 at 14:47
The engineer had my laptop in a thousand pieces to replace the motherboard. Seems to be working fine now. I'll mark this as the answer to close this question. – Bernhard Hofmann Nov 10 '11 at 6:33
Thanks! Glad to hear it was resolved, definately a hardware failure - hope it was under warranty! :) – HaydnWVN Nov 10 '11 at 11:51
