Update: Read the followup here
My Thinkpad that I bought used a year ago has the dreaded memory slot failure that results from a design error in the memory slot design found in almost every T30 manufactured. What happens is that after some time of usage and heat generation one of the memory slots cease to function. Since the T30 only has two slots from the beginning, this severely restricts the amount of memory that can be installed now. 512 MB of Ram is getting a little to slim because I heavily use VMWare on my computer, running one guest operating system as well as my Linux host system.
IBM did replace these faulty motherboards for a time, warranty or not, but that service ceased in the middle of 2005. Since the warranty on the machine expired in May 2006 and I bought it in August, I’m a bit annoyed of having to live with this problem. The previous owner apparently did not know about the free replacement if still under warranty.
After having spoken to a lot of support technicians on IBM/Lenovo the last week there is apparently no chance whatsoever of me getting a free/cheap motherboard replacement. I have tried to use stacked paper under the memory cover, but this does not work well enough. I finally called the Swedish spare parts office at Lenovo to find out what it would cost to replace the motherboard, just for the fun of it.
Luckily, the guy on the spare parts division was just the person I needed to talk to. This was an experienced, friendly technician who works more with the actual machines more than talking to the customers. He really knew about the problem with the model and confirmed what I had observed. He explained the problem to me:
- First, there is to little space between the memoy cover and the memory modules, not giving the modules enough space to cool
- The small space also means that having the laptop in your lap puts pressure on the memory modules themselves
- There is a minor design error in the hard drive sled which is located just above the memory that also contributes to overheating
- There is a blue plastic shock damper deep inside the computer that puts too much pressure on the memory modules from underneath, eventually loosening the solders between the memory slot and the motherboard.
He told me that what I could do is to get the machine to an experienced solderer to solder up the connectors on the motherboard. He pointed out the group of connectors that is affected. The problem can be seen if looked through a magnifying glass and pushing on the memory slot. Let the solderer put on quite a lot of solder, preferably of the lead-based type and not the silver-based one since lead makes the solder more soft and flexible. He also sent me the new type of hard disk sled and a new design memory cover for free!
This solution will last some time, but the main culprit is the blue plastic shock damper. Even with a re-soldered motherboard it will just be a matter of time until the solders get loose again. What really should be done is to take apart the whole machine to get deep inside, remove the plastic shock and put it all back again. He told me it would be a big job to do, and since the machine probably will last another two years without it. Still, I’m not sure what to do here.
For all of you out there who have a malfunctioning T30, there is still hope outside the warranty. If your warranty is out; Sorry, no free replacement form the support team. Document MIGR-44772 does no longer exist on the Lenovo servers since they apparantly have removed it. (MIGR-44772 was an internal IBM/Lenovo document describing that the T30 owner shoud get a free repair).
Most of all I am happy that I was able to speak to a guy at the spare parts division that really knows what he is talking about, and that he sent me these parts for free. He even gave me the address to a local shop here in Västerås that is really good at doing these soldering jobs for a low price.
This afternoon I am going to the shop to check out what they can do. Right after that I am buying myself a new battery that my job pays for. Finally being able to work unplugged! Wee!

Hello, would you be able to tell me exactly where the group of affect connectors are, on the motherboard? I had a look myself will the motherboard out completely, even using a magnifying glass – I was unable to spot any broken solder joints. Any response will be appreciated.
Thank you.
I would like to echo Heston’s comment. My T30 began exhibiting the memory slot problem a few days ago. I too, completely disassembled it and was unable to visually locate anomalies of any sort, even under magnification. I cleaned the innards thoroughly, put some fresh thermal transfer compound ‘twixt the cpu and heat sink–which made quite a noticable difference in heat output and fan usage btw–but I still have the slot problem.
Usually, the computer will not boot at all without a couple of bits of cardboard in the right spot. Right now, interestingly, I have non-corrugated cardboard–a few mm thick–directly on the plastic memory connectors themselves, not touching the RAM chip boards at all. This seems to work well for me and certainly does not contribute as much to ram cooling problems.
It seems obvious that I have the T30 slot syndrome, and I would like to effect a permanent cure–I’m quite capable of doing the soldering myself, even on smd’s–but I can’t find anything obviously wrong. Exactly what and where and how many things should I be soldering? Is there an image available?
Thanks
Greetings from Finland! I have repaired a few T20/T30 series Thinkpads using a very fine-tipped soldering iron (a Metcal, a Weller will also do) and a stereo microscope. In my opinion the memory slot repair procedure does and should not need application of any extra solder as mixing different solder metals (conventional tin-lead mixture used in older Thinkpads or lead-free tin-silver-copper solder used in newer Thinkpads) is not recommended, and it is rather difficult to tell which solder has originally been used. Actually the needed amount of solder metal is already there in the joints – the only problem is that there are cracks that do not conduct electricity any more.
However, it is advisable to use liquid soldering flux applied to the solder joints with a small brush or a “flux pen” prior to re-heating and melting of the individual solder joints one by one. The flux penetrates the cracks in the old solder joints and it will help to remove the oxide layer in the crack when the existing solder melts, producing a good-as-new solder joint.
As spotting all the broken memory module slot joints is by far not easy even for a professional with the best available equipment, it’s best to fix all the solder joints if you decide to go that way. There are as many solder joints to “flux and re-solder” as there are pins in a memory module. That is, 144 joints for a T21 or 200 joints for a T30, and you’ll need to double this number if you are going to use a memory module in both slots! But it can be done, given some time and patience.
This repair procedure is suitable for a skilled electronics hobbyist with access to the tools mentioned above. If you don’t have a stereo microscope, you can also use a jeweler’s loupe, good loupe glasses or a very good magnifier for viewing the work area. However, most likely you can’t spot ANY of the micro-fractures of the solder joints unless you have a decent stereo microscope with a magnification between 10X and 40X. Of course, a very steady hand is also needed for this repair job!
Hope this helps someone
I just found out about this problem when I got an addition RAM chip for my T30. Installed it, and presto, no extra memory!
After a quick search I found this page and the entry on Thinkwiki.
I have temporarily “solved” the problem by rolling up a rubber band and placing it between the chip and the RAM cover. The area of contact between the band and the RAM chip is quite small, so it shouldn’t cause much trouble with heat dissipation. It is working quite reliably, surprisingly enough, though I will eventually need to do something a little more thorough than this…
My my my. I am really distressed about this. One of my memory slots stopped functioning about 2 weeks after i purchased my Thinkpad T30. It was used and i got it about 2 months ago. I thought the fault was with the RAM chip. i changed it, and it still refused to work. I run applications that consume lots of memory, and i am really frustrated. This page has given some info and how to fix the problem. But I live in Ghana and I have no idea where i will find someone with the experience required to fix the problem.
Well, I also got this problem with my t30. I went to the local service (I live in Russia) and they re-soldered all connectors of the slot. Now it works. They charged 50 Euro for this job. But, I still worry because it could happen again. That’s why I would like to make some steps to prevent it. You wrote this “What really should be done is to take apart the whole machine to get deep inside, remove the plastic shock and put it all back again. He told me it would be a big job to do, and since the machine probably will last another two years without it.” What do you mean under “since the machine probably will last another two years without it”? Does it mean that the machine will only work two years and that’s it? Would you please explain. Because I’m about to take this blue plastic away and would like to be sure that it will cause no damage and the machine will function without it
and without any problems. Thank you!
@berlinmoskau:
I can only recite what the spare parts guy at IBM told me, but here is my understanding of the situation. He told me that re-soldering the modules will be a good fix for the problem, and that it will last a long time with only that. However, to make the machine last even longer with that repair, you need to remove the shock absorber. He assured me that it is a really difficult task and needs exact understanding of the machine. He told me the solderings will last “2-3 years” until they wear out again if the shock absorber still is there, since the memory modules will be exposed to prolonged physical stress. Removing the blue thingy should make the fix almost permanent.
Take a look at the maintenance manual for the T30. It should be available on the IBM homepage, and it describes every step of disassembling the computer.
I can only assume that the computer will work without the shock absorber, since that was what he told me (and it sounded like he knew what he talked about).
Be sure also to replace the memory slot cover with the newer, more robust type that reduces physical stress on the modules when the computer is in your lap.
Hope this helps,
Jonathan
Well, I took apart the hole machine and would say it wasn’t so difficult. You just should be careful and that’s it. I found the blue plastic under the motherboard. And now there is another question. This article http://www.thinkwiki.org/wiki/Problem_with_failing_memory_slot says that it would be a good practice to place a well-supporting soft padding (thick adhesive tape etc.) between the installed memory modules and the memory panel/door that covers the modules, preventing this problem from occurring again after a few years. This means that the the both slots will be pressured to the motherboard and will be fixed. That’s right. But! In this case it doesn’t make sense to take the blue plastic away because it also make pressure and the slots will be pressed from the both sizes and will be unmoveable. What do you think is the point to take away the blue plastic in this case?
Since we are talking about T30, I’d like to ask whether somebody knows something about the bluetooth daughter card? I want to install it because as far as I understand there is a slot for it. But in my machine there is a modem card in this slot. I found a card (bluetooth & modem together), it was in T41 and wonder whether it will pass in T30. If anybody has an idea I would be glad to hear it. Thanks.
I have not yet done the surgery on my computer.I would advise against putting padding on the modules, since the whole point is trying to keep them cool and not affected by external pressure. Therefore we also remove the shock absorber, to decrease physical stress.
berlinmoskau: Regarding the bluetooth question, I ‘m pretty sure the card from T41 would fit, but you need to hook up bluetooth antennas. Correct me if I’m wrong, but most of the T30 models doesn’t have antennas installed. Shouldn’t be too hard though, you just need to lift off the keyboard, attach the antenna somewhere and run it through a hole close to the fan assembly to connect it to the card on the other side of the board.
I’m now off to find an electronics repairer that can solder these freakin’ solder joints. Thanks 2 Jonathan, (søta bror:)), for enlightening me with how to solve this issue, I thought it was a lost cause until I found this page. Even the thinkpad forums (forum.thinkpads.com) did not have any info on this. Maybe its time to open a thread there…
polarity, I guess you are right. There are no extra antennas for blutooth. But there are antennas for WiFi. It means that the extra antennas must be installed and I think they should be layed under display (but probably it is not necessary). Anyway I think I’ll try to do it and as far as I have any results I’ll leave here a report.
Jonathan, thank you for this very useful post! It helped me to repair my T30 (which I like very much in spite of this problem with the slot. Anyway it functions again).
So I found an experienced solderer that did the job for me, and guess what? The Thinkpad is still dead… Suggestions anyone? I refuse to give up on it..
First of all you should realise that there could be another problem than one with the memory slot. You write your ThinkPad is dead. What do you mean, what are the symptoms? Secondly, the master must be must be experienced in computers repair as well.
There could be to answers: your ThinkPad has another problem or your solderer is not enough experienced in computer repairs. Did he solder all the contacts or only some of them? In any case, describe what is happening with your ThinkPad and how it all began. Hopefully we find out what the problem is.
Andrey
tnx for that usefull site. one of my t30 is working with only 256mb now. i searched the web for solutions and found a commercial site, where they offerd repair for that problem. now i will do it myself!
btw: bios update worked fine without windows with the cdrom method.
I also own a T30 and was affected by the memory slot problem about a year ago. Only the front slot was affected, which from what I can gather is the most common case. I “fixed” the problem by installing a 1Gb module in the rear slot. Contrary to specifications this actually works and the full 1Gb is recognised. My model is 2366-R7G (P4 2GHz) with BIOS 1IET64WW (2.03b). The memory module was bought from Crucial and is officially for a Thinkpad T42 type 2373 system. Part number is CT433386. It’s a 1GB, 200-pin SODIMM, DDR PC2700. You may need to flash-update your BIOS; having said that my BIOS is quite old (see above) and recognises the memory just fine. No problems 1 year down the line. By the way, I wouldn’t have known you could do this without the forum at http://www.thinkpads.com. Highly recommended.
berlinmoskau, my T30 is not fully dead. It boots up every now and then, and after the solder job it seems to boot up easier than when on battery. Also, after soldering the memory slots detect both sticks (512×2) when it is able to boot.
The solderer had never soldered a laptop before, but then again, who has? But he is a pro, soldering microchips for some kind of industrial machines. He checked the joints for cracks but could not see any, so he re-soldered all the joints with flux. He also said that there was way too little solder in the joints originally, and figured that it could be a contributing reason to this common problem, eg. the joints crack easily and lose conductivity.
I also took the laptop apart so that he could check the inductors on the underside of the motherboard to see if they had any cracks in the joints. Loose inductors has been a problem in the T23′s (fixed one a year ago), and I’ve read posts by people experiencing the same problem in T30′s. The inductors were not loose in this case, but had a few very tiny cracks. He did not think this could cause a problem, but re-soldered them just in case. Turns out he was right though..
So, now I’m gonna call IBM to see if they can do anything about it even if it is out of warranty. If that fails I’m gonna keep my eyes peeled for a working T30 motherboard. If all that fails, I have a half working T30 w/DVD burner and 60GB 7200rpm hd for sale if anyone’s interested:)
Spot-on information. Same problem here with two Thinkpads T20
Hi Jonathan: First of all I would like to thank you for your very valuable site as I too am the proud owner of two “Dead” T30′s due to the RAM issue. Been using the cardboard to get by. Anyway my question is does the Mobo have to come out to do the soldering or can it all be done from the RAM access compartment ? I have had alot of experience soldering and am going to give this a try. I don’t have much to loose as one unit has one dead slot and the other unit has two dead slots. Thanx for your help.
Hi FH, I have a T30 type 2366 97U with the front slot not working. I tried a 1 GB module in the back slot and it worked. You made my day! The module that I used was a Kingston, KVR333X64SC25/1G. Its description is: 1 GB 333 MHz DDR non ECC CL 2.5 SODIMM which seems to be similar to the one you used.
@Kawasaki: Sorry, I haven’t dared to re-solder the board, but I guess it could be done from the memory compartment.
T30 – DIMM COVER PLATE Compatible Part Numbers:

Thanks to all for the excellent comments to clarify this issue.
I discovered the problem with the front socket on my T30 while upgrading memory. I am able to boot with memory in the “bad” socket by applying pressure to the RAM compartment cover in the area of the front socket using my finger during POST. Going to BIOS first (pressure no longer needed) shows all memory is onboard. When OS restarts, it too shows all memory present and diagnostic memory tests run OK. All memory persists even after going to standby and back!
Applications have not encountered any [memory] errors yet, so I’m wondering why pressure on the “bad” socket is needed only during BIOS boot? Is my socket bad only in a [soldered] connection used in the POST process? That seem like a rare coincidence.
Am still thinking of having connections resoldered, but have a workaround… for now.
Is the “blue shock absorber” the one between the speaker unit and the hard drive?
Leon:
Maybe not so rare. I, too, have only had to apply pressure on startup for the memory to be recognized. I had assumed that there must be a presence-detect line that wasn’t getting good contact. Now I know why.
My T30 had a pretty scary fall the other day — about a four-foot drop, landing flat on its lid onto a hard floor — while running. I had feared hard drive head crash, cracked or swirly LCD, and case fractures. But a sector scan finds no bad sectors, screen is still beautiful, the case has no new fractures, everything seems to be fine; as it turns out, the only apparent damage is that my memory slot problem has suddenly gotten worse. Pressure during POST still allows that front slot to be recognized, but I get frequent BSODs during operation. If I take the stick out of that front slot, it runs fine (albeit slightly more sluggishly).
Rather than trying to solder, or paying to have soldered, 200 tiny joints, I figure I’ll squeeze a little more life out of this 7-year-old machine by just replacing my 512+256 MB sticks with one 1 GB stick for the back slot. If the back slot eventually goes, too, then it’s time for a new laptop (now if only Lenovo made them as well as IBM made them).
I see people here getting 333 MHz PC2700 instead of the 266 MHz PC2100. Does anybody know if that higher speed memory only works on the newer T30s with faster (2 GHz) CPUs, or if I can use that in my 1.8 GHz 2366-85U?
Hin and thanks from me too.
I’ve invested in a new T61 (at a bargin price 9.995 sek incl 3Gb). After have seen how much RAM will affect the performance I went back to check how much mu old T30 had installed, and the BIOS info told 256M, even though I had 2×256 chips installed. When I removed the extra it still showed 256…..
I then did a Google search and found this info.
I will now invest in a 1GB chip and install as the primary one and hope this will do the trick.
Feedback. The 1gb chip (cost 560 sek) did the trick. The T30 runs as never before. Once again thanks for the info.

Hey guys i have a t30 and wanted a gig of ram hey serprise! the front memory slot is dead, i have a couple of these units cheap as x-tech computers so i will be experimenting with blue spaces and needle soldering irons, but i dont think any1 has clicked on to the bios upgrade yet! i found the bios update allows the unit to accept 1gig ddr ram sticks, so i flashed the bios on 1 of the units, threw a 1gig stick in the good ram socket, saide a prayer and it works! i know its a work around, but if im able to repair 1 of these thinkpads, that means i can load it with 2gig! awsome:) hope that bit of info is useful.
thanks for this helpfull info,now i know why tiger direct never emailed back.took me 3 yrs.when i first realized the problem it was past warranty. i have two 256s in there now,it is only displaying 256 in sys info, and wonder if the 512 i just bought will work?? sure i would love 1g but i dont think it will work.plus the 1g memories are way hard to find and i think they dont want you to try to use one because of the heat.
I had the memory slot problem. Sent it to Hammerhead Technology. They fixed it and I couldn’t be happier. Hammerhead has all the expensive flow soldering technology to fix the problem the properly and have done the procedure many many times. The price is right too.
I wana ask a question from here before.
Paul MartinPosted Friday, July 4, 2008 at 01:14 | PermalinkIs the “blue shock absorber” the one between the speaker unit and the hard drive?
Anyone?
kcmojo:
as far as i can remember there is only one blue shock absorber present, so yes, that would be the one.
Update on my T30 situation:
It’s been in use for about half a year now. gave it to my sis and told her never to turn it off, just put it to sleep:) It still detects both memory sticks, but it still has a hard time turning on after being turned off.
I’ve seen videos and posts by people who reflowed the solder in the ATI chips in the T40s with hair dryers(!) I wonder if this method can reflow the soldering in the T30s memory slots… Anyone care to try??
Link to T40 hair dryer reflow:

Quick and cheap way to go around this issue: My T30 type 2366 has 1) this memory symptom on one of two memory slot 2) so XP was crawling with 256MB of RAM. From opening the memory slot found that the memory socket stand slightly higher than the case and likely have touched the memory cover. So any physical contact to the memory cover will disturb the memory sockets and loosen solder joints. Workaround: 1) To get around the memory deficit with 1 working memory slot, I updated the Bios and the embedded controller found on IBM website and stick in a 1GB PNY PC2700 that was on sale at BestBuy for $43. 2) Kept the memory cover from touching the socket by partially covering the memory slot. This is done by leaving the side opposite to the screw afloat and tape in place and screw in the screwed side. Used a black electrical tape to cover the gap. This method works great and my nephew and niece enjoy playing on the computer now that it is usable to play online games. Enjoy!
Hi, Guys,
does anybody can navigate a pictorial / video for removal / installation of MB on T30 IMB THINKPAD?
I have dissassembly by IBM but it is schematic drawing.
could you,please, e-mail a website?
Thanks.
Just discovered problem on my T30 and trying to find best solution, will open ram door and look for broken connections tonight
My front slot has 2 cracked connections on the last few solder joint, I moved my 512M ram stick into back slot (took out 256M) and performance is great. Now I want to fix it all up ie repair solder joints, 5400 drive and a gig and it should be terrific.
Touched up the last solder joint on the RAM slot contacts. Very minimal solder originally did not help. Anyway all is well now and it see both sticks. Machine is lightning fast surfer now and I am not even going near the hard drive for now.
@burns334:
Good you fixed it! Hope the memory slot continues to work.

I came across your site, while I was searching to solved the IBM Thinkpad T30 2366 booting problems. Finally, found it’s the DVD/CD-RW and HD failure and not the memory slots cracks. I replace the HD and also bought a new Thinkpad T30 DIMM Cover Panel Memory Door 26R7892 for $1 at Ebay, excluding SHIPPING. (The seller and I are in CA, I paid $4.90 for S&H). This is a new slightly “raised” door. I like to share it with your viewers
http://cgi.ebay.com/IBM-Thinkpad-T30-DIMM-Cover-Panel-Memory-Door-26R7892_W0QQitemZ360228402702QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item53df49360e
Disclaimer: I have not relation or connection with the Ebay seller.
I may have this issue in a T42 p used laptop I recently purchased and just bought memory for that isn’t recognizing. Any new info on this issue since it is May 2010
Using a flux pen, a 1/64″ conical tipped iron at 30watt and .015″ diameter silver-bearing solder I successfully resolved the issue by adding additional solder to the outer row of connections on the rear facing dimm slot.
Apply flux to every pin.
Apply heat to each pin right before it connects to plastic and feed a tiny bit of solder at the start of the pcb smd pad.
Don’t be too scared of creating jumpers, the flux and existing solder from the factory keep things lined up well.
I can confirm this is a memory slot issue as I have had a troubled t30 for 2 years. Applying pressure to the memory slots by sticking a wedge between the slots and the memory cover plate is a temporary solution in my opinion.
Thanks for your web site, I have an old T30 with this problem. Following the advice here, I took my common soldering iron and pointed the tip with a file. Then using a magnifying glass to look through, I simply touched each joint for a few seconds to melt the solder, resetting the joint. It seems to have worked, no need for additional solder or flux.
Been through a lot with the T30. Memory slot problem is fixed by:
1. Replace memory cover with steel cover with raised area for memory chips.
2. Do not remove shock absorber for hard drive. Instead apply pressure to 2nd memory chip from inside with a shim. the shim is made with 2 face shock absorber tape wrapped in electrical insulated tape.
3. Install this shim to the thickness to get the Bios to recognize the memory.
I currently have 1.5 GBytes running with 1 GB in the 2nd slot and 512 MBytes in the bad slot. Two memory chips are better because they reduce the thermal concentration to do over activity on the one chip.
I also have a 320 GByte Western Digital Scorpio Pata. Getting this to work is more tricky. Key is to create three partions about 105 GBytes each. There is a Bios problem with the T30 and it will not support above about 128 GBytes. If the partition is too large it will never find windows; but do not fear, just reduce the partition size with the drive in an external USB drive container.
Keep the C drive small and it will defrag a lot faster. Also schedule Microsoft backup to automatically backup the system files on one of the other partitions. Use a flash drive or 2nd hard drive to back up critical files. Note you cannot copy partitions trivially in Windows as there are absolute drive paths, so creating a backup partition is really not as easy as it seems.
I operated with the 1 GB kingston for awhile but started having memory problems in that slot until I shim’ed the 2nd slot with the old 512 GB RAM. One problem is the hard drive and memory together can run very hot.
One other thought. Putting the hard drive in an Ultrabay 2000 might alleviate all of these problems and distribute the heat throughout the computer better. Seems ok until you need to run a CD program then the hard drive has to move moved.
The T42P is the fastest thinkpad that takes a PATA drive if you need to upgrade and want some kick.
Nevertheless with these suggestions, you ought to be able to get more out of the T30 war machine.
To find loose pins, use a scope and fine probe to see which ones move slightly. They will be a long the edge.
Reflowing the solder improved reliability. Just put the fine soldering point on top of the pin and push down for good attachment.
I was able to get the slot working by cutting a piece of closed cell packing foam to fit over the connectors (but not the actual memory as I am concerned about the heat issues) I was able to see the 2 gigs that I installed and this machine has gone from something I was ready to throw in the swamp, to a new friend.
Thanks to all for the ideas that led me to the solution.
Thanks for the post.
Brought the T30 to work and re-flowed the memory socket joints and I am back to 1GB !! Added solder to a few that seemed lacking. Could see cracking on some but only when I went up to 400x mag.
Symptom was 2x512M installed and only 512M recognized. Neither 512M dimm would be seen alone (boot failure ?).
How do you know if your IBM ThinkPad is a T30? I was just given this computer in January and, since having problems with it in the past couple of months, have looked up and down for information about it. All I come up with are:
Machine type: 2366
Model: 85U
Serial: *******
Can I assume that ALL 2366-85U’s are T30′s? Or, is that a false assumption?
Here’s a thought; if the cover is pressing on the memory, causing the problem, how avout putting a spacer under the edge of the cover, so it sits up a bit higher. This should keep the problem from re-occurring.
