2366-96U System Board Replacement and CPU Upgrade

#1 Post by Doodd » Fri Nov 18, 2011 3:30 pm

First time posting and need help. My system T30, Type 2366-96U. system board, FRU 91P7212 (Replace with FRU 91P7698). CPU Intel Socket 478, SL6FK, 2GHz, OS WinXP. With security chip. My T30 died and not sure if the system board memory slots cracks or the CPU overheat. The fan, the copper plate excessive burnt areas at the edges between the fan. I am now waiting for a used upgrade CPU 2.4GHz SL6VC, bought from Ebay.

1. Can I replace Type 2366-96U, system board FRU 91P698 with system board FRU 91P789 Without security chip.

2. Can I replace Type 2366-96U, with any system board Type 2366-XXX

3. Since I bought a Intel SL6VC CPU (2.4GHz), will it work on the replacement system board either, FRU 91P789 or any Type 2366-XXX

I have found a 2.4GHz fan FRU 91P88908 and will buy later.

This questions may have been asked umpteen times, I am new and find it difficult to navigate in this forum. Please do excuse me. Thanks

Welcome to the forum.
Both mobo P/N do not exist.
For T30 there are 2 groups of mobos, the standard one (26p8205 w/o and 26p8328 with sec-chip) for CPU up to 1.9GHz.
For 2.0GHz and higher you need the 'motherboard 2' group (91p7211 w/o and 91p7212 with sec-chip).
Lower CPU will work on any of the 4 mobos.
Physically any mobo will fit in any T30.
You can swap a mobo with for a mobo without sec-chip, hardly anybody ever uses that sec-chip in a T30.
I would advise strongly against the 2.4GHz CPU, it runs way too hot.
2.00GHz is the perfect happy medium.

Thanks for the quick respond and appreciate the information.
Below that's where I found the mobo P/N. According to you my
mobo will be in group 2.

http://support.lenovo.com/en_US/product ... MIGR-42335

If the P/N does not exist, how come Ebay selling 91P7698 and
91P7689, can you please explain? I am not a computer geek.
I should have ask the seller these P/N 26p8205 w/o and
26p8328 or 91p7211 w/o and 91p7212.

OK, I'll take your advice and not use the 2.4GHz SL6VC, but
to use it to test my existing board when it arrive.

Can you advice whether the 91P7689 mobo (Ebay below) falls in
group 1 or 2. I almost bought it, but came here to check it out.
if my existing mobo is bad, I still need to find one in Ebay, ASC
or elsewhere. I now understands security chip.

Thanks again

Those P/N do not exist, next time please check for typos, especially with IBM P/N or FRU numbers!
1 digit missing or 1 digit wrong makes quite a difference.
The (correct) P/Ns in your last post are replacements for the original T30 mobos.
91P7689 = standard w/o sec-chip
91P7698 = type 2 with sec-chip
Be aware that lots of mobos have only one RAM slot working, so (if not specified in the ad) ask seller if both slots work 100%.


The mentioned eBay auction has been re-listed.
It is for an IBM-refurb'd mobo, so it should fully work.

I've bought stuff in the past from this seller and was very pleased. YMMV.

Thanks, he is very helpful. This mobo FRU 91P789 is motherboard 1' group or assembly 1 mobo, and advised me not to buy for 2.4Ghz CPU. That was before RealBlackStuff explained to me.

I have bought both fan and CPU (not with me, I'm overseas), undecided if I should go ahead, buy for testing. I'm having problems with this T30. Most of the time (99%) will not bootup, just plain screen. I could use this mobo to test, like swapping parts.

Any suggestion where to find a mobo 2' grouping that cost under $40. Thanks again everyone. :-)

Honestly, I'd rather have a Type I planar coming from a trusted source than having to go out of my way - or my mind - to source a Type II board.

The difference in performance between 1.9 and 2.4 is really not that huge. There are many other bottlenecks on T30 that can't be removed that I really wouldn't sweat over the issue of not having the most powerful CPU available.

My $0.02 only...

The problems is not that want to upgrade to 2.4. My existing CPU 2GHz. This T30 was OK, till last year it will not bootup and I thought the mobo bad. I look for a mobo. Unknown to me being new, might as well upgrade, bought a 2.4GHz and used fan.

I don't have the CPU or fan with me now to test. I don't have the slightest idea, whether the mobo, CPU, or the keyboard is bad. The push "on" button tends to stuck when depress and remain "down" position on one side.

How and where do I begin to troubleshoot? I don't think the memory slot is bad as it did start once last week for a few minutes. In BIO, it correctly indicate the ram installed. It could be the memory slot, I did insert a cardboard depressed the ram and installed back the cover.

Can you suggest what should I do beside throwing it away. I would like to use it as spare. Thanks.

Addition info. The T30 given to me free, and I bought new 80Gb HD preloaded to factory and 3 preloaded CD. Lately 2.4GHz CPU and a fan. I have already invested far too much to throw away.

I never said that you should throw anything away...

My first shot would be to remove the RAM from both slots, and try booting with one slot populated at the time only.

Let us know if intermittent booting continues when only one slot is used.

Good luck.

I had already tried that several times, including using original ram (forgot to include brand new 2X500 memory), with and without cardboard, still the same. I'll try again later just to sure. Thanks

I remove the Ram, did exactly only one slot. I also tried again switching from 512MB (new) to the original 256MB, same sequenced. Same no booting - 5 lights momentary on and off with only the "power" light remain on.

I did another test, removed the 160Gb HD, two partitions ("C" "X"). Hook it up with external USB cable to another laptop. Format first with Partition Magic version8 and again with WinXP. Reinstalled, and it did bootup. I have forgotten to “bootup from CD”. I immediately inserted T30 recovery CD. Too late it hung. I tried to reboot again, the same black screen. I need to clarify "black screen" mean plain black, but if I switch off the room-light, the screen is "lighted" with only the "power" on. It seem every time (not always once in a while) when it momentary boot up, was when I removed, switched or do something with the HD. I hope I am clear and need your advice to go further. Thanks.

Walking away is easy for me since no one responds further. Future newcomers, clueless as me may have similar problems. These vintage get older and more T30 may need to rejuvenate, I may offer some insight how I overcome some problems.

The T30 running on and off, the problem is the keyboard, needs to be replaced. Once booted it will continue to restart without problems so long you do not switch it off. The CPU and everything are OK, except the TPfancontrol - "APC" reading as high as 90C, during PC5 testing. The fan needs replacing. The edge’s copper sheet between the fan duct is excessive scored, when disassembled, cleaned the fan of the heavily restricted with "stuff".

With PC-Doctor 5 testing, many keys not working. To boot the computer, external power must be disconnected and start with its battery. It may bootup with few tries, wait for a few hrs or days to bootup. Once on it will restart repeatedly. Once bootup I immediately attach the external power to saved the battery life.

I refer to, t30engstg_67p4720.PDF, nowhere any indications how begin troubleshoot. The manual shows the "date" need to reset almost every time the battery and memory remove. Numerical error "0251 : System CMOS checksum bad". The rear (2) slot "may" also bad and I have 1Gg slot 1 and Belarc indicate 1024MB and 256MB slot 2, which seem odd to me and need to find out more.

I am open for questions and need especially to thank RealBlackStuff for the initial contact, you are highly praise for your knowledge in NGs. Your navigation link helps me to find TPfancontrol utility and not forgetting ajkula66, for the memory check. I still have a long way to go to rejuvenate this T30. Anymore advice will be most welcome. Thanks again. Excuse my typo. :-)
