Troubleshooting and Diagnostics 

ze1000 Series Troubleshooting and Self-Repair Guide 

•  Many countries impose a blackout period after a modem repeatedly fails to connect to a service 

provider. The number of failed attempts and the period you must wait before trying again differ 
from country/region to country/region: check with your telephone company. 

 

For example, if you are dialing from Italy and fail to connect to your server or cancel the 
connection, you must wait one minute before dialing that number again. If you dial before then, 
you will get an error message that says “delay.” After the fourth failed connection, you must wait 
one hour before trying the number again. If you dial before the hour is up, you will get a message 
that says “black list.” 

•  Check the telephone number you entered, including any digits required for outside access or long 

distance. 

•  In Control Panel, open Phone and Modem Options, and check the dialing options—look for 

duplicate digits for outside access or long distance. 

•  Make sure the number you’re calling isn’t busy. 
•  If you have call-waiting, disable it—see Windows Help and Support, and contact your telephone 

company for information. 

•  Make sure you’re using an analog telephone line. You must not use a digital line. In a hotel, ask 

for a data line. 

•  Try another telephone line, preferably one normally used for a fax machine or modem. 
•  The modem at the other end may have a problem. Try dialing to a different modem. 

•  The host modem may not support a 56K (V.90) connection speed. 
•  Connection speed depends on several factors, such as the condition of the telephone line. Try 

connecting another time. 

•  Make sure you’re using an analog telephone line. You must not use a digital line. In a hotel, ask 

for a data line. 

•  Make sure the telephone line goes directly from the notebook’s modem phone jack to the 

telephone jack on the wall. 

•  If you have a single telephone line for voice and modem use, make sure no one else is using the 

line and that the phone is not off the hook. 

•  Try another telephone line, preferably one normally used for a fax machine or modem. 
•  Contact your Internet Service Provider (ISP). It’s possible that service may be unavailable 

temporarily or that your settings are incorrect. 

•  Restart your notebook and attempt another connection. 
•  Download the latest modem driver from the technical support area of the HP notebook Web site 

(www.hp.com/notebooks). 

•  Run the modem diagnostics:
