Aptiva - Modem not detected with parallel device connected
Applicable to: World-Wide
On 2137 and 2138 machines with non voice modems some customers have had difficulty with the modem not being detected when a powered on parallel device is attached to the LPT port. To resolve the modem non detect problem, follow these steps:
1. Power off or disconnect any devices (such as printers, scanners, or zip drives) which may be connected to the parallel port on the rear of your system. Reboot your system.
2. When the system has completed the boot process and entered Windows, check Device Manager (Start - Settings - Control Panel - System - Device Manager) to see if the modem is detected. If the modem is detected, this power on sequence has resolved the problem. There may have been conflict between your parallel port and modem. We suggest turning the parallel port device on or plugging it in after the system unit is powered on. (If the customer does not agree that the modified power on sequence is an acceptable resolution, replace the modem.) If the modem is not detected in the Device Manager, proceed to step number three (#3)
3. Standard modem problem determination:
(Internal IBM Technicians Follow steps outlined in RICK Tool)
a. Ensure the phone line connected to the modem correctly.
b. Run PC Dr. diagnostics on the modem.
c. Ensure that under Modem Properties, the "More Info" button on the Diagnostics tab displays correct information.
d. Uninstall and reinstall modem the drivers.
e. Reinstall latest version of the modem drivers.
f. Restore the original config.sys, autoexec.bat, win.ini, and system.ini files
(IBM Business Partners: For further assistance with modem problem determination please visit http://www3.pc.ibm.com/support/ and create a user profile. From there you can access our Knowledge Base and follow question / answer format problem determination. )
If these steps do not resolve the problem proceed to step number four (#4).
4. The edge connector of the modem may be corroded or dirty. Cleaning the connector with a red pencil eraser removes the corrosion or dirt. Follow these procedures:
a. Go to Start - Settings - Control Panel - Modem. Highlight and remove ALL installed modems.
b. Shut the system down.
c. Remove the cover from the system.
d. Physically remove the modem from your system.
e. Clean the gold 'fingers' on the edge connector of the modem with a red pencil eraser. Light pressure is sufficient. Brush off any dust or rubber fragments.
f. Reinstall the modem in your system.
g. When you boot the system, it should detect the modem and install the necessary drivers. Only one modem should be installed in Device Manager. If this does not resolve the problem proceed to step number five (#5).
5. If the previous steps did not resolve the problem then it is possible that the modem is defective and will need to be replaced in accordance with the terms and conditions of the machine warranty.
