Ibm Thinkpad T23 Boot Problem

Hi guys!

I also have a T23 with a fan problem. The laptop won't boot at all, I get a FAN ERROR on startup, I don't hear the fan running at all... It did that to me 3-4 times before but after a couple of reboot it was OK. But now it'S dead...

I took it apart last night and checked the board and there was nothing loose. I put some pressure on the magnet and it's not loose at all.

What can be the problem? The board or the fan?

Do some of you know how to test the fan, what voltage do I have to send to it to test it and what are the 3 wires going to it? Wich one is positive and negative...

Thanks for your help!

Ive had the same problems as described here by a few people. Ive taken it apart and the solder joints on the little "magnets" seem firm. however ill reattach them and see if that does the trick.

please le me know if anyone found any other weak spots on the MOBO!

cheers guys, great help, i hope to report back with some success.

Run PC doctor. There is a file available on the Lenovo site that combines all three diagnostic discs onto one bootable CD, but this is all I can find at the moment.

Now I'm suffering the same problem. People in forum told me it's the problem of the fan. Too much dust has gone inside which stops the fan from running normally.
The solution is to clean the fan, and then reinstall it.

i have a T23 and when i try to start it up nothing happens i mean nothing no lights no fan not a thing i took it a part and don't see any problems i tested it with a multimeter its geting power but it don't do anything and that one magnet is still on the board please help

Lonely,
You try to remove the battery installed and then reboot. Sometimes loose battery may cause boot faliure.
Another cause might be the input current.
If not, the problem must be on the mother board.You'll need to consult the technician.

I Know what is wrong with the Thinkpad.
The problem is the built in thremal sensors.
If thea malfunction the pc wont start.

I had the same problem a few days ago and was already considering selling this off on eBay and getting a new laptop.

Now I have hope. I disassembled the system, and sure enough, one end of the connection was broken, and the other readily broke off when I touched it.

My soldering skills aren't *that* great, so I will have to wait a few days for a person who is good with this to do this for me.

Hopefully I will be able to put all the many pieces together again.
(By the way, anyone know what this little component actually does?)

I agree, this seems to be a manufacturering problem with IBM and they really ought to do something about this.

Just to update, once the piece was resoldered, the T23 booted up very
nicely (in fact I am using it to post right now).

Thanks again for the original poster of the images/solution to this problem,
it saved me lots of $$ and time/hassle to be able to fix the problem myself.

Thanks to twmspro and everyone for this super information. I had similar problems and found after dismantling the tp that the same soldering repair was needed. Got an iron from Radio Shack at 8:45Pm and fixed it. Some what sloppy soldering but I haven't soldered for a long time! Put it back together and worked fine except...The machine now shuts down after 10-30 minutes of operation. I think it's overheating, the air coming from the fan is hot as is the bottom of the computer near the cpu. I did not replace the thermal grease (neither RS nor I had any last night). Could that be the problem? Thanks in advance for the help.

I have the same exact problem however I have an IBM R50P. Is the magnet placement the same? I checked the component that looks like the one above and it seem intacted.

Hi,

Here is one for you, I have a beep message and no boot up on my daughters T23 model 2648. It is either 1-3-3-1 or 3-3-1 do you include the first beep? and then it drops out leaving the power light on and the fan running?! Have whacked in a boot disk but nothing. It is running xp pro and I have forgotten the spec as we have 3 laptops here and 5 at work!

Any help or advice would greatly appreciated. I have not been inside the machine yet.

yes, I'm sure you include the first beep.

1-3-3-1 has something to do with ram on Ibm Thinkpad T23

Also, the error codes at the bottom of this site might come to some use to some people.

I had the exact problem with my T23, i spent 5 days and didn`t figured. After a google search i found this forum and with twmspro`s informations i resolved it. My IBM works again.

@twmspro many thanks from over seas!

I have the same problem. Has anyone contacted IBM about this problem? Any responses?
