Suggestions

Make sure notebook’s modem is properly connected to wall telephone jack. Check cables.

Verify settings in Control Panel. Make sure parity, speed, word length, and stop bits match on sending and receiving modems.

Restart notebook.

Run Windows modem diagnostics or modem troubleshooter in Windows Help.

Open Device Manager. If modem is disabled, enable it. If it has a conflict, try disabling another device.

Use analog telephone line, not PBX or digital line. In a hotel, ask for data line.

Try disabling error correction and data compression.

Download latest modem driver from technical support area of HP notebook web site (see page vi).

Check number you entered, including digits required for outside access or long distance.

Check dialing options in Control Panel—look for duplicate digits for outside access or long distance.

In foreign country, modem may not recognize dial tone. In Control Panel, disable option that waits for dial tone.

Disable call-waiting.

Check for excess line noise or static (often difficult to eliminate on international calls). Contact telephone company if needed.

Disable call-waiting.

Eliminate extra connections in the line. If possible, connect directly to wall jack.

Try another telephone line, preferably one used for a fax machine or modem.
