T30 powers on, no boot, no screen, no error?

hopefully someone can give me a few pointers on this. I'm guessing i may need a new motherboard but if there's something else to try...

The main symptoms are the t30 starts (all status leds blink) but then does nothing with only the battery led remaining on. The cpu fan spins. No hard disk activity. No screen (lcd or external). No beeps. It stays like this cpu fan spinning until you press the power again to switch off.

I've removed keyboard, bezel and memory and generally checked connections but it generally does the same.

tried some memory from another machine, it either powered down instantly or gave one beep-three beep-three beep-one beep error which indicated dimm or board. Refitted original memory 'cured' this.
On one occasion it gave four beeps cycled four times.

Anything to try or is it new mobo time?

Looks like new mobo. Check the part-number/FRU that you have now, and get the same type.
There are 4 different motherboards for the T30, so check carefully.
Get the HMM here: http://www-307.ibm.com/pc/support/site. ... MIGR-42308
Has all the instructions, part numbers etc.

It can be a loose memory socket.

Loose memory socket would cause the machine to beep.

This is likely a GPU failure which doesn't happen often on T30s, but will poke its ugly head out in one of 5,000 pieces or so...

I had a similar case where fuse 5 was blown.

My T30 just went South on me per above as well (except not even CPU fan). I'm thinking fuse as I heard a distinct 'tic' just as everything went black.

I figure I'd just swap the system board. Problem is, my model doesn't appear on the Lenovo site (2367-2UO). Nor can I seem to 'decode' the matrix to find the proper sys board part number. My T30 has NO security chip but DOES have the onboard ATI Radeon 7500 chipset.

Anyone know the part number for a ATI equipped (SXGA+) board without the security chip?

There are 4 mobos for a T30:
26P8205 standard without security chip (also under no's 91P7689 and 30L3057)
26P8238 standard with security chip (also under 91P7692)

91P7211 system board 2 without (also under 91P7695, 26P8422 and 93P3804)
91P7212 system board 2 with (also under 91P7698 and 26P8433) <<<<<<<<<< CHANGED

Look for the part number or FRU on your current T30 mobo.

Look up the list in IBM's tawbook, and see which T30 comes closest to what you have.
(see the forum with the FAQ).

All mobos can take XGA or SXGA+ and have the same ATI Radeon 7500.

Alas the wiki articles don't mention the 2367 models at all and it seems the link to the tawbook is no longer good (?).

Looks like I'll have to disasemble the T30 to find the proper PN#. What a PITA.

What's the difference between the standard system board and the system board 2?

westsailor:
I think that you are reading your model number incorrectly. 2367-2U0 does exist at the Lenovo site, but note that the last digit is a 0 (zero), not an O.

Original description: Based on 2367-88U: P4-M 2GHz, 512MB RAM, 40GB HDD, 14.1 XGA(1024x768) TFT LCD, 24x10x24x/8x CDRW/DVD, Modem(CDC), Ethernet(LOM), Li-Ion battery, WinXP Pro

Aha, that simplifies things.
The 88U has the System board 2.
These have different CPU-coolers amongst other things, and are the boards for 2.0GHz and higher CPUs.

Well, I still don't see any 2367-2U0 zero) on that product matrix

But that pretty much describes my (orig) config. I'm curious tho. I always thought I had an SXGA LCD since I was able to use 1280X1024 (and capable of going higher if I remember correctly, just too teeny on that 14" screen).

In any case, I really do appreciate the help in noodling this out. Although I just bought a T60 I do want to repair the ol T30. It's been a fine tool.

Thanks to your help... I know the exact PN# for the system board I need. I love this forum!

You can use either system board 2 with or without sec-chip.
Get whichever one is available and/or cheaper, as long as they are sys-2.

The sticker on my used replacement system board reads "fru 91 P 7695 ll PC", a system 2 board as best I can tell. I've been using origonal 1.8 cpu and fan(system 1) with no problems, I guess, because this is a downgrade to the system board. My question is this. What happens when a system 1 board, like origonal 1.6 is upgraded to a 2.2 or 2.4. Is there hardware failure or bios issues? Been wondering about this for a while. Thanks!

With the lower CPUs (under 2.00GHz), you can use any board.
There are differences in the board layout for higher CPUs (2.00 and up), but I could not tell you exactly.
I only have T30s with system-2 boards at the moment.
I don't think the higher CPUs will work on the lower boards, but I can't really say.
Don't think the BIOS would stop the use of higher CPUs on a lower board.

RealBlackStuff, Thankyou for the reply! Been thinking about upgrading a extra 1.6 MHz T30 I keep as a spare for the wifes 1.9 machine. 2.4 cpu's are often cheaply available on EBay, but the matching fan is always somewhat pricey. Guess I'd better wait before trying this mod. Has anybody out there tried this? My concern is the increased current draw thru those incredibly tiny components and traces. Thanks to Bill Morrow and RealBlackStuff for such a great forum!

Just in case, the 2.0 CPUs are the most common ones and are also the 'sweet spot' for T30s.
There's no point to go higher, you'll waste battery power and the extra heat is not pleasant either.

Bummer! I have a 2.4 GHz cpu and matching fan on the way for this 1.8/sys II T30. What you say about the 2.0 makes perfect sense. So, I'm thinking I'll go ahead and install them since i have them, investigate modding the heat sink similiar to what I saw in some T4x thread or site, download and learn to use TP Fan control utility, and rebuild a old battery pack with higher capacity cells. I'm definitely going to leave stock cpu's in wifes 1.9 and 1.6 T30's due to the points you made. Great advice. Thankyou!

Just to follow up my original post it would appear to be a faulty system board.

obtained a new board, fired up first time. Happy days! (and thanks for the advice)
