Having problems with your Dell Latitude C640 Notebook ?

Modem problem i have error in modem that in device manager properties says modem is installed and working properly when i dial a phone number for net connection then answer that dial tone is not received and modem is not installed properly.


Answers :

Disconnect the phone line from the modem and connect a normal phone to this phone line. Lift the handset and check it you have a dial tone and see if you can dial out.
