I have just bouth a new battery pack, thinking the other was not charging because was damaged. My bad surprice is that the brand new one, don´t charge also.
My laptop is a IBM thinkpad T40, and it works ok with the AC adaptor. Also worked ok the battery till got discharged. Seems that there is a bug on the power section that doesn´t allow chargint the battery. Do you think is any solution for me?
I think otherwise I would have to replace the maiboard, what would be quite expensive, or maybe buy a external charger.
Any genious here could give me a light?

My laptop doesn´t charge "nothing" the battery. IT continues on 1% anymore.

You have to take the laptop apart. There is a fuse on the battery terminal board that has blown. I bet that if you get he instructions or some one that knows how to take the laptop apart you could find it and resolder a new one on. OR if your comphy taking the laptop apart you could do it. Im sure you could search google for dsimantling pictures or even call ibm OR go to a authorized service center to get a tear down book. Im certified for many laptops so i don't need them but if you need help just ask.

Does the battery information show up in power manager? Left click on the battery icon in the task bar, and select launch power manager, then click on the battery information tab.
i fix a lot of ibm laptops, there are chargers out there.

there are a few models where the pcb for the charger can be removed without replacing the mainboard. but im sure that model
is not the one😉
ibm is bad for that.

The battery icon on Xp shows 0% charged. Yesterday showed 1%.
I have opened it. Have to removed the modem board, and a little board that conects to the lcd to can see something. It has some IC, and could see a fuse F2, I couldn´t see anyother fuse, but this one seems ok.
I have checked also the backup battery and is ok also.
It seems not easy to repair for some with no experience on this, would need a miracle, or maybe some service.
Any of you could repair it for an aforable price better than bying another used one on ebay?
I´m opened to repair myself, but I think I would need a guy who know this model and the jungle components there.

Do I need the IBM battery charger? Or could build a charger with a current AC at 10.8V plugged between pin + - of the battery? If this just work ok, would quite easy to do...??
Since your ac adaptor works and the battery has been replaced I think its safe to eliminate those items.
I don't work on IBM's but that does not matter much.
It sounds as if the dc / inverter pcb, whatever IBM calls it has failed.
Its job is to take the power from the adaptor and invert if necessary and channel it to both the battery and the motherboard.
Some computers (usually older models) have this board as a daughter board which seats on the motherboard. Other models have it integrated into the motherboard. If it is separate then you can replace just the dc board otherwise its a motherboard replacement.
Some companies will do a repair / exchange with your old motherboard so you do not pay full price.
In any case, maybe you should see your friendly neighourhood IBM service centre so they can confirm the issue.

Here's a possible solution
Most laptops have a power jack with internal mechanical switch that can become damaged when the unit moved and pluged in to the power adaptor. This is a common problem. It does require unit dismantling and solder work. Maby even part replacement if too badly damaged. This will prevent batery for being connected to the charger during operation with the power adaptor pluged in.
Best of luck

That is old technology.
You need to defiantly replace the Inverter board for the battery. Its the plug that the battery will plug into on the laptop. Id phone ibm if you can and get that part explain to them its a older laptop and it is not under warrantee they will sell you the part OR look on ebay. 😀

But seems that the inverter is built-in the motherboard. No adicional board on the input.
Please reply to the question of charging the battery. Can build a charger with a 10.8 V AC conected to the +/- points of the battery? or need the oficial IBM external charger? Do it need to use all the 5 pin of the battery to charge?

YOU need a special charger its not a simple positive and negitive. the battery has many pins for thermal checking charging speeds to see how fast and slow it is charging & it's discharge rate.. you will have to start searching ebay for a new main board i bet its about 50$ ish.. Or look on the board for main fuses. Post a picture of it so i can look.

The only camera I have, is too bad and only takes photos ok with a dictance of more than 1 meter.
I´ll try to find a photo on internet.
The maiboards I´m seeing on ebay all are used and over 100$, I´m not sure about how secure can be buying a used board..

Well i buy more things on ebay than i do in a store. So its pretty secure. Use paypal and you wont get hozed over.. Also send me some links to these main boards..
email is jase @ jasesspace. com
I have acces to the componets, but my camera can´t focus that.
I woul need someone who can get access to schematic or experience on this mainboard.
I have tried 3 fuses that are ok. Don´t know if there are any on the backside of the maiboard. I can see also two TPC 8014 and one TPC 8109, maybe could be there the issue?
Or do you think I would better go for another mainboard on ebay?

Buy the mainboard BUT make sure you can return it if it has a problem. IOW I would be careful about buying a board from an individual. Again, try IBM, its an older board so there are probably no more computers under warranty, therefore the price will be more reasonable. If not IBM, perhaps a third party dealer on the net that does repair / exchanges. Most manufacturers give a 90 day warranty on the parts they sell (but they may want to install it themselves).
Also bare in mind how cheap some notebooks are nowadays. If the board costs say $250 and you can get a new computer with a warranty for $399 then I would find the extra $149, just something else to confuse😉 I mean consider😉
Or maybe a good used notebook.
You can always put the hd from the defective notebook in an external enclosure so you will still have your data.
Forget about the diy battery charger, its not that simple and its not something to play around with.

I have bought a maiboard that comes with processor, and base. Just to conect hd, pcmcia, ram etc, to work.
