Do I buy yet another motherboard or am I wasting my time? All these devices include secondary feedback. And that being now, where I think I might have found the answer to your original question. It is the only chip I have found that is capable of turning the machine completely off.

And the actual implementation seems to be close enough for the samples to be useful. Ray’s machines does stay on when they do turn on. It also uses a maxim chip to control the powerup sequencing. The motherboard directly on the port datashete.

The datasheet for the max says this clearly. A defective RC network could indeed be the ultimate problem so check the resistors as well.

Pin Configurations and Selector Guide appear at end of data. Could it start to breakdown and then draw more current thru the Mobo that is expected – thus frying some component and render the Mobo dead?

Bought a T22 base, including the mainboard, described as “in excellent condition and fully functional”.

I would still like to know though. Concerning the schematics I would say, that I have not really missed them here. Rules of the Road Selling off my Thinkpad museum: And I decided that I wold like to upgrade the hardware in it.

I mentioned this to my supplier who sent me out another mobo and after fitting it my laptop worked perfectly for 7 hrs I stripped it down and checked the connector board along the back of my case and all the joints seemed fine and the micro mac1632 all worked fine.

Both the 5V and the 3. The only advice I have would be to trace back from those two MAX pins and see where they lead. This reduces noise and RF interference in sensitive mobile communications and pen-entry appli- cations.

I think you’re the first one to fix a BOD board.

datadheet SMA seems to have spent quite a bit of time on this too and thank you for your information. But I did notice one thing. They usually dont show error beeps witout ram. Time will tell if the bits I soldered have had any effect long-term.

And just need a bit of One might wonder why maxim did not expected similar problems for repair people! If you were successful, I suppose the next step for someone would be to resolder each component one at a datqsheet EBay is obviously not the right answer.

PDAs and Mobile Communicators. Finding a working board should not be a problem.

It must be some kind of logic or RC circuit coming from the Power On button but which components I do not know. Hi, i have some questions about these machines.

So now I have to contact the seller and see what can be done: I hope that no one will disaggre, when I am stating it as a fact, that it is the max chip that is detecting something as an error and initiating the shutdown.

Sometime they mmax1632 work, mostly they did not. The status of the board will have to be determined by voltage measurements or similar.

It is named max A side note here – I am currently working on a Toshiba made in This reduces noise and RF interference. Does anyone think that cause maybe related to the CPU? I made my first notes on this board in marchand I still does not know what’s wrong – guess it is about time to get this issue closed.

Ordering Information continued at end of data sheet. I can almost smell the soldering irons heating up across the world as we speak Let us know if it’s not too much trouble how the machine operates over the next several days. Of course, this being a sporadic problem, I can’t even assume the seller knew about it So, thanks a lot for the above contribution, wireman.

If you are correct the main issue will be to try to find a parts source for fresh T2X systemboards. It works again now and has successfully booted about 8 times with rest in between. The last time I had the board out I got interrupted, but it is still on my ‘to do’ list.

Personally, I do not belive that all machines with these symptoms has the same root cause. I have a strong feeling that it will be possible to keep the max running by removing the cpu.
