No dialtone error on Thinkpad T42

[Melvyn]

Hello,

This is my first post, so excuse my ignorance (maybe).

I've buyed a Thinkpad T42 2373 M1U from ebay 2 weeks ago. It came good. I used it for 2 days before formating and I got connected with dial up.

I don't have recovery CD, drivers cd, etc. Nothing but all drivers were at Partition D:\

I rebooted and reinstalled a new, fresh copy of Windows XP Profesional with my previous laptop's cd (a Dell OEM windows XP CD). Everything got ok. Installing drivers I found 2 folders with modem's stuff. I installed from there. After that I got to IBM site connected via ADSL. Software Installer did it's job. No working with Software update. Everything is up to date.
My modem is recognized as: ThinkPad Integrated 56k modem.

The Problem:
The modem gets "no dial tone" error when trying to connect via dial up.

I tried disabling "wait for tone before dialing" and nothing.

I have years working with computers, I've solved almost everything, I don't want to open this notebook losing warranty and I'm sure that can be solved with 3 clicks because I was getting troubles with Bluetooth and that got solved renaming a file.

I'm sure theres an issue with IBM drivers and Microsoft drivers.

Somebody with similar experience?

For starters, you purchased an IBM. The very last thing I would do is install a Dell recovery CD to it. Try to get a proper set of recovery CD's here or on eBay and do a proper job of recovery. I have not seen an IBM ThinkPad (ever) that would not light up the modem out of the box.

In the meantime, right click on My Computer and select Manage. In Manage, select Device Manager. In Device Manager, expand modems. Right click on your modem and look through the tabs for normality and for the tab that says the driver is installed and working. Then under Diagnostics, query the modem. See what answer it gets, and let us know here.

You could have a defective modem, or the driver may not be correct or installed properly. Good luck. ... JD Hurst

Hmm, I only read the top half of your post and see that you did post the query results. Sorry about that. It says it recognizes the modem, so maybe there is a hardware problem (bad modem, bad connector).

I have a T41 and the modem file I downloaded and used does not look like yours, but I may have a different modem.

Then under Diagnostics, query the modem. See what answer it gets, and let us know here.

The query is in the last post.

My Dell's CD is just a Windows XP Profesional CD. It don't install dell tools, no dell's drivers, nothing. Just a fresh copy of XP. Anyways I have another cd (windows xp sp1 in spanish) original from microsoft. I installed at other partition and the result is the same.

With Bluetooth was similar and it got solved deleting or renaming the bth.ini file at c:\windows\inf, so I suspect that a similar solution can be posible.

Query result:
ATQ0V1E0 - OK
AT+GMM - +GMM: ThinkPad Integrated 56K Modem
AT+FCLASS=? - 0,1
AT#CLS=? - COMMAND NOT SUPPORTED

Sorry I did not read all the way to the bottom. My apologies.

Also, I was on my Desktop (different modem), so now I am looking at my Laptop. I get (on Query)
ATQ0VIE0 Success
AT +GMM H.324 video-ready rev. 1.0
AT +FCLASS=? 0,1,8
AT#CLS? COMMAND NOT SUPPORTED
and so on.

So this is similar to yours, and so I am starting to think hardware problem. ... JD Hurst

When you do a New Modem Connection, are you selecting the correct modem? My New Connection wizard offers me All Available, 2 SafeNet miniports (you won't have these), and Agere Systems AC'97 Modem. The default selection is not the modem. So I am just checking that aspect with you. ... JD Hurst

I've configured dial up connections hundreds of times. It's the correct way.

The matter here isn't user configuration, it's hardware. Like Bluetooth. My knowledge can't find the right answer as "remove theese files installed by windows"

hehe

It's a thinkpad issue, I'm sure.

Hello,

Solved! (almost)

Two months after original post, I've reinstalled windows (several versions) and Linux on another hard drive to test with/without updates, drivers and so on. Always no dialtone. 5 cables were tested, all of them works with desktop pc, none with thinkpad.

Well, today I was trying again and "discovered" that Thinkpad modem is good, in a way:

When I connect from wall to desktop pc and from desktop pc to thinkpad I get dialtone and can connect. I've tried a lot of combinationes with the cables and it works with everyone.

I can use that when pc desktop is shutdown (either with no power)

wall line -> desktop pc -> thinkpad = Good connection.
wall line -> thinkpad = don't work.

So, it's a cable compatibility issue.

Some light to help me in final solution?

Edit: So, it looks like a RJ-11 / RJ-14 issue (or something so)
