I have an Inspiron 8200 running XP Pro. I don't know when it happened (I usually connect to the internet via LAN), but XP can no longer detect the built-in modem. In My Computer>System Properties>Device Manager, there is no entry/icon for Modems. Background: last year, my 8200 had major problems with locking up on boot. It made three unaccompanied trips to the repair depot. (I finally solved the problem by reformatting and reinstalling XP Pro, software, and data.) So it may be possible that on one of those visits to repairland, the technician forgot to plug in a cable. My network connection works fine. I'm running A11 BIOS, and there is no setting to enable/disable the modem controller. Is there anything else to check before I crack the case and check the physical connection?
