Intermittent problems Intermittent system hang problems can be due to a variety of causes that have nothing to do with a hardware defect, such as cosmic radiation, electrostatic discharge, or software errors.
FRU replacement should be considered only when a problem recurs. When analyzing an intermittent problem, do the following: 1. Run the diagnostic test for the system board in loop mode at least 10 times. If no error is detected, do not replace any FRUs. Rerun the test to verify that no more errors exist. Undetermined problems If the diagnostic tests did not identify the adapter or device that has failed, if wrong devices are installed, or if the system simply is not operating, follow these procedures to isolate the failing FRU do not isolate FRUs that have no defects.
Verify that all attached devices are supported by the computer. Verify that the power supply being used at the time of the failure is operating correctly. See Power system checkout on page Visually check each FRU for damage. Replace any damaged FRU. Remove or disconnect all of the following devices: a. Non-ThinkPad devices b.

If the problem does not recur, reconnect the removed devices one at a time until you find the failing FRU. System board b. FRU replacement notices This section contains notices related to removing and replacing parts.
Read this section carefully before replacing any FRU. Screw notices Loose screws can cause a reliability problem. In the ThinkPad computer, this problem is addressed with special nylon-coated screws that have the following characteristics: v They maintain tight connections. Tighten screws as follows: v Plastic to plastic Turn an additional 90 degrees after the screw head touches the surface of the plastic part:.
Cross-section v Logic card to plastic Turn an additional degrees after the screw head touches the surface of the logic card:. Cross-section v Torque driver If you have a torque driver, refer to the Torque column for each step. If you have a torque screwdriver, tighten all screws firmly to the torque shown in the table. Never use a screw that you removed. Use a new one. Make sure that all of the screws are tightened firmly.
Retaining serial numbers This section includes the following descriptions: v Restoring the serial number of the system unit v Retaining the UUID on page 68 v Reading or writing the ECA information on page Restoring the serial number of the system unit When the computer was manufactured, the EEPROM on the system board was loaded with the serial numbers of the system and all major components.
These numbers need to remain the same throughout the life of the computer. If you replace the system board, you must restore the serial number of the system unit to its original value. Before replacing the system board, save the original serial number by doing the following: 1. From the main menu, select 1. Set System Identification. Select 2. The serial number of each device in your computer is displayed; the serial number of the system unit is listed as follows: v Serial number Write down that number.
Note: The serial number of the system unit is also written on the label attached to the bottom of the computer. After you have replaced the system board, restore the serial number by doing the following: 1. Select 1. The algorithm that generates the number is designed to provide unique IDs until the year A.
No two computers in the world have the same number. When you replace the system board, you must set the UUID on the new system board as follows: 1. From the main menu, select 4. Assign UUID. A new UUID is created and written. If a valid UUID already exists, it is not overwritten. The electronic storage of this information simplifies the procedure to check if the ECA has been previously applied to a machine.
The machine does not need to be disassembled to check for the ECA application. From the main menu, select 6. Set ECA Information.
To read ECA information, select 2. To read box build date, select 5. To write ECA information, select 1. To write box build date, select 4. If the system board is being replaced, try to read the ECA information from the old system board and transfer the information to the new system.
If the system board is inoperable, this will not be possible. Be sure to observe the following general rules: 1. Do not try to service any computer unless you have been trained and certified.
An untrained person runs the risk of damaging parts. Any such FRUs are listed at the top of the page. Remove them in the order in which they are listed. Follow the correct sequence in the steps for removing the FRU, as given in the drawings by the numbers in square callouts.
When turning a screw to replace a FRU, turn it in the direction as given by the arrow in the drawing. When removing the FRU, move it in the direction as given by the arrow in the drawing.
To put the new FRU in place, reverse the removal procedure and follow any notes that pertain to replacement. For information about connecting and arranging internal cables, see Locations on page When replacing a FRU, use the correct screw as shown in the procedures. Before removing any FRU, turn off the computer, unplug all power cords from electrical outlets, remove the battery pack, and then disconnect any interconnecting cables.
Attention: After replacing a FRU, do not turn on the computer until you have made sure that all screws, springs, and other small parts are in place and none are loose inside the computer. Verify this by shaking the computer gently and listening for rattling sounds. Metallic parts or metal flakes can cause electrical short circuits. Attention: The system board is sensitive to, and can be damaged by, electrostatic discharge.
Use only the battery specified in the parts list for your computer. Any other battery could ignite or explode. When installing: Install the battery pack along the slide rails on the left and right sides of the battery-pack slot.
Then make sure that both battery latches, a and b , are locked, as in the following figure. Note: When you release the switch in step 1 , the lever pops out. In step 2 , pull the lever a little to release the device from the bay. The hard disk drive is sensitive to physical shock. Improper handling can cause damage and permanent loss of data.

Rename the bookmark. Delete bookmark? Cancel Delete. Delete from my manuals? I suspect it is a memory OR motherboard problem. The laptop works no problem if placed on a flat non-moving surface using the touchpad but it will lock up if the trackpoint mouse is used. I removed the extra memory module, etc, but still not improvement. Thanks so much for this tutorial! Put both so-dimms into a T The T42 booted beautifully into XP Pro.
Been using the T42 a lot for the past couple of days, with no lockups or blue-screening. Thank you for the really great advice. I never thought I would remove my entire keyboard and be able to put it back and the laptop still works!!! Now my laptop is asking me to install new hardware. I am not sure what to do now. I am not sure this hardware is on the list the computer has for me to select. Any suggestions. Your laptop detects new hardware after upgrading the memory module?
It was working properly until yesterday, when a blue screen says out of memory. Now, when I took the 2nd memory out 1Gb , It works fine. When I put the module in the notebook, It do not start. Do you know what could be wrong? Thanks in advance. I have done this procedure at least 10 times in some t40s Some of hem worked aswell but some did not function anymore when I plug the jack it flashes de battery led once, and if I push the power button it flashes again but no power comes. I have a T41 laptop.
It had 2X MB memory cards when I got it. I then put the MB card back in the bottom slot and put the 1 GB card in the slot under the keyboard and it worked fine and recognized all 1. Found the following ram available on some site. I just worked on a T43 type which takes DDR2. Other than that, the instructions above are correct for this machine.
The www. This machine does have a slightly backlevel BIOS v1. I tried restalling XP on the Laptop but even during the installation process it would freez.
Please help me what could cause such a problem. There is no simple answer to your question. First of all, I would suspect the laptop memory. If you have two memory modules installed, try removing them one at a time. Test the laptop with only one memory module in place. This way you can find the faulty memory module. If you have only one memory module installed, try replacing it with a known good module.
My T42 does the same — Pulled both modules. Tried booting with 2 1GB PC modules, no go. Each 1Gb Module works in each slot. I have a T42 Series laptop that I got a number of years ago and I use it for business travel. I love this computer and recently had it set up with all of the newest operating systems as well as Picasa picture viewer and several adobe applications for my work. In doing all of this I had the gentleman who set the computer up take all of the big RAM using graphics out that were slowing down my run time but the computer is still slow.
I would love to know how much RAM I can put into this computer and if it will make it faster because now it is a 2 cup of coffee computer just to watch it start up.
You can install up to 1GB memory module into each slot. It depends. If you have only MB installed, upgrading it to 2GB will definitely make your laptop faster. Hi, i have an T42 and my laptop has ram and 60Gb of hard disks space. I had this laptop since and now after all these years the computer has become slow, i like my laptop because its small and light weight.
Now i would like to know if i upgrade the ram to 1 or 2 GB would i be able to run smoothly windows 7 or vista, and is there any way i could also change my hard drive.
I have a ThinkPad T42 myself and really like this laptop. I have 1. Go with 2GB if you can. I believe you can safely upgrade to a GB hard drive and maybe even GB drive. Can you recommend where to purchase and what specific memory disks I might need? These days you can purchase laptop memory everywhere. In a local electronics store or Internet. If you have more money than time, go to the store.
If you are ready to wait for a few days, buy it online. All you need to know is the memory size and type. I guess you want to get 1GB module. What harddrive do you recommend? Will the computer automatically recognize the new memory or are there additional steps once the memory is installed? There are many different brands out there. I cannot recommend any particular brand. The new memory module should be detected and configured automatically.
No additional steps needed. I changed the memory in my T42 and now am having trouble with my screen going in and out I removed nothing but the keyboard. I have a IBM T The bio is showing 2gb installed. Any idea why it is locking.
