T43 1871 motherboard replacement question

hey, i posted before about my USB going dead,
I am getting a PCMCIA card to remedy the situation for the time being, but for the long run, i have another possible solution to my problem.
Will an IBM T43p motherboard fit in a T43 1871 case? from an initial look it looks like it has the same ports and looks about the same size..
Also will be 1.73 centrino work in it?
Solved!

Yes, it will fit and PM 740 will work, however, you'll have to get a different fan/heatsink.
Please be advised that T43p boards tend to run very hot due to V3200 GPU, and you might be in for a rude awakening after an Intel-based unit. If your frame is a 14", it will run even hotter.
I'd strongly suggest getting another Intel-based board for your T43, but it's your call.
Good luck.
Cheers,
George

T43 1871-CTO fan 26R7860 replace with 26R8197

Hi all,
I have a 15" T43 1871-CTO (Product ID: 1871Y2G). I am very pleased with it. I bought it used two years ago. Now my fan is very loud and is causing me headaches. So I bought a replacement fan 26R8197 from IBM. When I opened the computer there is:
26R7859
FRU FAN SHORT
26R7860
Is this (26R7860) an original fan for this laptop? Is it possible that it should be 26R8197 from the start?
Also, screws don't look like the correct ones (according to the service manual).
Next questions:
- there are five black stickers (look like stickers) in the box. What should I do with them?
- about the grease? How can I tell that the grase is already applied on the heatsink?
Current FRU does not cover the GPU (that on the right is GPU, right?) which this new FRU can cover. Do I need to remove or do anything with these heatsink spare parts (FRUs)?
Thank you for your help.

Welcome to the forum!
That "short" fan is not the original one. Take a look at the bottom picture on this page, that's what your setup should look like:

IBM (at least around here) pre-applies thermal grease.
Good luck.

Which Motherboards can i use to replace T43-1871-AB9

Hey again,
im in the market for a new motherboard as i am experiencing a southbridge failure. Now i have found several around but i am wondering what models i can use my current is the
T43-1871-AB9
Any help would be appreciated.
thanks a lot.

You can use any T43/p motherboard, they will fit in your base.
If you get one with ATi graphics, you'll need a different fan/heatsink, but that's about it.
Hope this helps.

(T43-1871-AB9) Trying to Identify the problem......

Ok,
As in the subject of this thread, i have a (T43-1871-AB9) and i am experiencing some very strange intermitten problems.
Every so often my computer will freeze out of nowhere sometimes when the computer is doing nothing at all, and sometimes when the computer is under stress (IE : Playing a game).
I've already come to the conclusion my southbridge chip is no longer working as my onboard USB do not work anymore. I purchaced a PCMCIA card to remedy this problem.
I fear my Motherboard may be the problem. I have tried several different things to fix my problem including replacing ram. ( i was using 2; 1 gig dimms and now am using 1; 2 gig instead - i have installed this into my main slot under the keyboard.)
Sometimes after i freeze i an unable to start up my computer.. Sometimes it freezes at the bios splash screen, sometimes it stays black and sometimes it freezes at the "Windows 7 Utlimate" Pre boot loading screen.
Just for some background the only way i can get the computer to boot after that is to make a change... usually i add a secondary dimm to the "expansion bay" to boost it up to 3 gigs ( yes i am aware that i can only use 2, but this seems to remedy my problem.) When it happens again i remove the extra ram and it boots just fine... so... perhaps someone has a clue where my problem is and if i need to replace my motherboard...
thanks a lot..

You can't re-ball the Southbridge chip by yourself, special equipment is required.
The only place that I know of that offers that type of service is GPU Medics (formerly known as Superior Reball) but they've gotten a lot of mixed reviews. You'll have to do some research and decide for yourself.
And of course, a motherboard swap is always an option.
Good luck.

R61I Motherboard Replacement

Afte rmany years my R61I 8918CTO 08/03 has given up the ghost due to the infamous
Nvidia Quadro NVS 140M.. GARBLED DISPLAY PROBLEM that Lenovo and Nvidia know about and of course refuses to fix now.
I have the 15.4" wide screen with 1900 max resolution, 1394 firewire, bluray writer and T9300 chip so it was a very expensive nice laptop that still does everything I want. I have taken very good care of it over the years and it is in excellent condition. Right now it is brick due to the GPU chip. Now my question is what is the Motherboard number without me taking it apart to get it before I have a replacement board and what motherboards replace it? AFter research I see if I can get the same motherboard after 08/08 it should be good. Or is there another motherboard with a better GPU chip I can use? I know this is an old laptop but it will cost over $1000 to get the same thing now just slightly faster with more memory I do not need so I would like to fix this one.
I have found what I believe is in the laptop either 42W7791 or 42W7882 both with the Nvidia chip. I cannot find a replacement with the Intel chip.
Thanks!

Post 08/08 boards are rare. You can contact forum member TuuS, he may be of help finding you a proper board.

There's the possibility of fitting a T61p planar (Nvidia Quadro FX570M) in your R61i case, but the frame needs modifications and there are other disadvantages. Source (german only): http://thinkwiki.de/R61i#T61-Board_im_R61-Geh.C3.A4use
Regarding the Intel boards, you can try to get one of the following FRU numbers listed below, there might be more, I got those from the hardware maintenance manual (you can download it from here: click me!)

Missing PCI serial port driver on elitebook 2560p after faulty motherboard replacement

Hi,
I have the following issue, after a faulty motherboard replacement on my elitebook 2560p with Win XP, I find a question mark in the device manager list reporting that a PCI serial port driver is missing.
Browsing device properties I can read:
PCI serial port - PCI bus 0, device 22, function 3
and
PCI\VEN_8086&DEV_1C3D&SUBSYS_162B103C&REV_04\3&B1BFB68&0&B3
I've already tried locating driver without success in SP38312, SP45131, SP53918, unzipping the files and trying to locate manually the driver inside the folders with the windows driver update function.
can you help locating the correct driver?
thanks a lot in advance

My '08 17" macbook pro motherboard replacement has issues

my mac had its motherboard replaced by the recall a couple years back and since i got it back it has been restarting on it's own, if have too much pressure on the keyboard or if the surface under (table) isn't perfectly level.
ONce it restarts - it won't stop until it's level and been powered off and on several times.
I had been living with this problem for the past 2 years as of this february (I believe) until it stopped for 24hrs 3 weeks ago and I was forced to buy again.
My buddy told me it could be because apple hired a 3rd party company to handle the replacements of the recalled motherboards and they neglected to tape a cable that causes the power surge to restart my mac or that they didn't solder the connection.
How can i fix this issue?

Sorry, let me clarify.
Yes, it was the Nvidia GeForce 8600M GT recall
It works, but suffers from restarts when moved from one location to another and must be restarted over and over until the power from the surge stops.
I want to figure out how to fix myself (I do alot of iphone repairs and can handle small fixes) or if needed through apple or a 3rd party.
I need it fixed completely, because I'm sending this to my computer illiterate mother.

Lenovo B560 motherboard replacement

Hi,
My dear laptop died on me about a month ago. It wouldn't do anything when pressing the power button and the power led would not light when connected to power. Tried with or without the battery, no led, no power. I checked with another cable and I checked my cable on another laptop and it worked so the issue has nothing to do with the power cable.
I took the laptop to my universities repair shop for a diagnosis and they said the Motherboard is dead.
Any suggestion where I could find a brand new motherboard replacement in the UK?
Thanks,

Qosmio F10 won't recover after motherboard replacement

Hi,
I'm having a problem with recovery on my Qosmio F10. It won't boot from the CD, I get a message 'media test failure check cable'.
I tried everything I could find here about this problem with no result. Then I read somewhere on this forum that recovery cd wouldn't work if the laptop has been serviced and has a new motherboard. This is excatly the case.
I had a new motherboard and CD/DVD drive put some time ago.
How do I make it work again?
A.

> Then I read somewhere on this forum that recovery cd wouldn't work if the laptop has been serviced and has a new motherboard. This is exactly the case.
Who has replaced the motherboard? The ASP?
Well, usually the Recovery CD should works after the motherboard replacement.
I presume the parts were replaced with exactly the same parts and therefore there shouldnt be a conflict between the Recovery CD and the new motherboard.
Did you try to boot from another bootable CDs like Win XP or Linux? Check this!

Everything is not working fine, and a pop with sparks is not a normal result from turning on a power supply. If you got it from Tiger send it back and get this one.
I talked to the rep earlier, but I had to go to a meeting. When I called him back he said he was on the phone with Intel to make sure my CPU would work with that board. I know it will work so I have no clue why he called them. He didn't seem to concerned about the PSU though. I told him that the PSU popped and made sparks and it didn't phase him at all. I already told him I wanted to exchange the RAM with different kind and I wanted a new PSU. When I give him the new RAM and the PSU I want I will give this one a try.
Thank you for your help.

HP G5056EA motherboard replacement

Hi Guys,
I'm replacing my motherboard as its dead, no sign of life when power cable is plugged in, it shows that charger is plugged in by illuminating power sign on the led screen where hdd light, power on lights are.
so assuming need a new motherboard. I've bought new one now struggling to open the laptop to get it out. I have removed
every possible visible screws from the back but it seems like one or two screws are holding it up from the middle of the laptop which It seems like they're screwed from below the keyboard.
I would apprecaite if someone can show me how to get this motherboard out, I'd really appreciate it.
Thanks in advance.

I don't think I will ever receive reply from HP tech support as I have rang them and they were unable to help me.
So far I have bought 18 laptops for my business and guess what all of them had one or the other issue. 2 of them needed motherboard replacing within 2 months,
Based on my experience with HP products and especially HP tech Support, I would never recommend anyone to buy any HP product from now on.

Thinkpad T400 Motherboard Replacement Advice

I accidentally dropped my T400 into water(Fell from a table into a water container). The service technician who checked it told me that motherboard's not working and has to be replaced. Now I am not sure whether to invest in the motherboard or buy a new one(I had a core 2 duo P8700 which is a decent processor and these days you get and i3's and i5's from $600).
Couple of things here is
1) T series right now would be outside my budget range.(student)
2) I am not sure if I would be happy with the lower end thinkpads/Dells/HP.
So any suggestion at thi\s point?
Would replacing a motherboard be worthwhile(The technician told me it would be around 300- 350 range.
Should I go with a new one or should I get the motherboard replaced?

Ouch...
What else is broken on it? Did any other parts survive the dunking- the screen, hard drive, RAM, battery, keyboard/UltraNav, fingerprint reader, speakers, or other motherboard modules such as WiFi and Bluetooth?
It might be a good idea to try to score a used one through the usual channels- they're around that costly (less than $450 anyways)- and just write off the other one, depending on how many other parts still work.
How much water did it fall into, anyways? Was it a full 5-gallon jug, or was it just an inch or two of water that killed it?
