Check out this link. There seems to be more than just one cause for this error message.
Hope this will help.
Windows Me
HP 7920 Pavillion PC
new hard drive installed (Maxtor 80 GB)
worked fine for two days BUT could not get on to secure websites - (email, other sites fine)
while downloading Windows Me Critical and other updates, pop up asked "wish to remove Lucent Win Modem". I answered "NO" and everything installed fine. From that point on could not sign on to internet (MS 9.0)
Everything else on the PC still works fine.
Error Code is 630 "port disconnected due to hardware failure". MSN said they could not help and call HP. I did, they wanted money and the person I was speaking with did not sound competent.
Any idea what the problem is? And can I fix it?
