Question about IBM ThinkPad T42p Notebook

6 Answers

Any touch will freeze my laptop IBM Thinkpad T42

My IBM T42 thinkpad would not start all of a sudden. The battery and AC power supply seem to be working fine. But everytime I start the laptop, there is a blank screen..the hard drive icon also does not blink.
However, if I persist and try starting it a a few dozen times, some time windows boots up and after a while everything freezes.

I was able to transfer all the data from hard drive through a SATA/USB interface. So, the hard drive is also good. The CD tray also works...so the laptop is getting power.

I suspect the problem is either to do with heat or some internal electrical connection. Would appreciate if someone could point me to some info on things I could try. Maybe a website that explains step-by-step or some general suggestions.

The laptop was working fine till 3 days back.

Thanks
Shashi

    I am having the same problem. Why is it that when you touch the to the right of the scroll pad, below the keypad, that it freezes up? What causes this?

    Does the recommended solution work? I can't wait to try it on my notebook.

    I have a T43 and it started to freeze up a few days go -- pretty much the same symptoms as described above. It seems that if I let the labtop cool down for a while, there's a better chance to start it up. So I suspect it's a heat related problem. But it still freezes up randomly even if I manage to start it up successfully. The notebook also seem to be sensitive to any slight motions.

    I have tried many things, including restoring the system to a previous good configuration, reinstalling windows XP, turning off start up programs etc. None of these worked. The fact that the laptop can freeze before or during startup seems to suggest this is not a software or OS problem.

    Any comments are appreciated!

    I have the same problem as described previously. Only rarely will the computer actually start up and when it does, it freezes shortly afterwards. I suspect a loose graphics card connection, as the hard drive and cd drive work properly.

    Putting pressure near the mousepad on startup seems to help.

    Well, dear all, as of my system is concerned, so the latest is, I have send the same for repair, i got it done perfectly. Now my surprise is why my RAM is being shown by my system as Half..earlier it used to show 764 and now only 504, I have 1 GB RAM installed in my system. Would any tell me whether I have been cheated by the repair center or its like my system is unable to detect the ram fully. Secondly, the ATI Radeon card is not been detected by the system, is it possible to remove it from the integrated mother board or that also is a problem with the system as system is showing new hardware found, VIDEO Controller (VGA Compatabile). Request you to kindly post some suggestions fast so that I can sue my repair centre if the same has something fishy?

There is a common problem with this machine; the mother board flexes and the processor mount partly separates from the motherboad. You tube posts a couple of solutions but they involve taking the laptop apart and applying heat from a heat gun to resolder the mount; it is not a solution for the faint hearted. Thinkpad/Lenovo might consider reparing the unit as it is basically a desgn/production defect but don't hold your breath.

This is an addition to the solution suggested by the person who recommended placing a thumb on the keyboard to right of the scroll pad just below the key board. I, too, have the problem described by everyone here. My computer freezes repeatedly. Sometimes it is during the first start up screen (the "IBM screen," sometimes while Windows is opening, sometimes when signing in and sometimes shortly after the computer is fully up and running. Occasionally - like others - I noticed that the movement of the computer seemed to affect this. However - I couldn't get the computer to function normally until reading the solution above. The one additional observation I have is that I don't believe this specific solution - "pressure to the right of the scroll pad" is necessarily the right solution for every computer, but some manipulation of the computer case or computer position IS the right solution. Thus, I've found that the computer works perfectly if I place a thin object (about 1/4") underneath the right, from corner of the computer does the trick. At another time I was using the computer on my lap and found that when the computer froze it would start again by slightly lifting the right front corner! Based on the comments here (and I tried several of the suggestions) plus my own experience, that this is not a software problem but rather something basically wrong (worn out, damaged) with the hardware. Thanks for the help to the person who suggested the pressure on the case.

I got a call this morning from somebody with this problem -- something I had never seen or heard of before.  I read what some people have tried, a few even going so far as to get out their soldering irons.  I'm not so adept with a soldering iron, so I looked for another solution.

Since the mother board is flexing -- and from what I've read, everybody has to push down in the middle or pull up on the corner -- I figured I'd try to stuff a piece of silicone in the middle under the keyboard to exert constant pressure.

Moving the computer around, flexing it this way and that, it no longer cuts out.

I`am having the same problem, except my screen it turns colors, and i would want to know how to fix this problem.

Posted on Apr 22, 2008

Try putting pressure to the right of the scroll pad just below the key pad when you hit the boot up button. If this works you are SOL. Not worth fixing.

SOURCE: IBM T42 does not start

And, a good day to you!
To start with, I have a couple of things for you to do so that we can get a little better handle on just what's happening.

First, let's remove the battery, all of the memory (both under the keyboard and on the bottom) and the hard drive. Then replace one of the memory modules in the slot under the keyboard, and see if it doesn't try to come up. Whether or not it tries to come up, go ahead and replace the hard drive and the other memory module and try to bring it up again.

While you have the keyboard out, check the area around the fan to see if it is crudded up with dirt and dust. If so, carefully clean that area.

This exercise may be all that is needed to get it fixed. If not, then continue on.

Secondly, I need you to try to power it on while you press down firmly (really press down) in the area just towards the front of the space bar and just to the left of the touch pad assembly. Hold it down while it tries to go through the entire power up sequence.

Then let me know what happened.

Ron-

Screen goes black when move or touch and start reboot


Operate your unit from battery, then use the unit with the charger plugged into AC. Try to recreate the failure with each power source. If it fails on battery only, you may have either an intermittent battery pack or poor contact in the battery bay.

My IBM T40 boots to a black screen with the "z"(light at top to right of power.


Try these steps:

1. Remove battery and unplug AC adapter
2. Press power on button for 30 seconds or so (one min is also too)
3. Attach battery and plug into wall
4. Power "ON" as normal

If you are still getting the "Z" and a black screen then I would have the video card or hard drive looked at and replaced. Start with the video card and then look at the hard drive

My previously healthy Thinkpad T42, will not post.


Hi,
The Thinkpad T42 doesn't have a reset button on it like the older IBM's used to.

There could be a problem with the battery. With the machine turned off remove AC power and then the battery. Plug in AC power again and see if the laptop will boot without the battery.
If it boots let it load up as normal and then shut it down again, reinsert the battery and try to boot it up. If it boots fine, if not then there is a problem with the battery.

Please post back if you need anymore advice.


Good luck.

Whops that sounds like a Mother Board Issue Common to IBMs.

What happens when you try to reload the O.S ? I would imagine it still shuts down. If over heats the computer will still turn on but not stay on, will shut down when the sensor on the CPU detectes excessive heat > 75 degrees F .

The problem is somewhere in the Power Supply flip flop Circuit System on the Motherboard most likely but thats academic!

You really cannot "repair" them, only replace them and usually that does not pay; the board costing more than the Computer is worth and Installing it is really a "Factory" Operation.

3. Put back the battery and plug back the AC adapter
4. Power ON the laptop as normal.

My T42 suddenly wont recharge the battery or wrk off mainsadapter


If the Laptop wont work off the power adepter, it also will not charge. The adepter could be bad (even if showing a power light) or the connector on the laptop could be broken. The best test is to take the battery out, attach the power adepter and try to start the computer if it starts, your battery is at fault. If nothing, suspect eh charger first. Be sure the pin on the Laptop power connector isn't bent or broken.
