T22 trying to revive

[Lethos]

Hello thinkpad community:

I have to confess, that I shot my notebook to death.

I had a broken keyboard bezel so I wanted to replace it. Everything was ok, until I wanted to connect the backup battery. The connector at the mobo broke away.
So my question is, can I revive the mobo or do I have to replace it?

Now when I push down the power button the harddisk turns, and the dvd drive also is under power, but only the processor light flashs for less then a second no other lights are flashing.
Also I cant turn off the notebook by depressing the power button.

I would be very delighted for any answer, or tip what else should be broken except the mobo.


Excuse my bad knowledge of the english language.

Lethos, the backup battery alone shouldn't cause all those problems. You should only have the annoying problem of having to reset time and date each time you boot up, and of course all your BIOS settings will be lost on shutting down. It looks like you have other problems as well. The usual procedure is to disconnect all removable devices, including battery and try to powerup. I normally take out the memory as well just to make sure I get the 3-3-1 or 1-3-3-1 beeps. Can you not resolder the backup battery connection? Also, reseat the keyboard and if the problem persists try to powerup from a port replicator (to eliminate the keyboard/keyboard connector as the culprit).

Thx for an answer. I have already tried to power on the system without anything connected including ram and battery but there is no sound else as the typical power on "puff" and the short blinking or that light.

When the hdd is connectedit spins as there would be no problem, but the processor fan does no noise for example, the dvd drive spins also.

It seems for me that there are at least to electricity cycles, one which just powers on the externel things like hdd and so on, the other the mobo its selve, and this one needs the backup battery perhaps?

I dont think that the matter is the keyboard, but I will check that with a replicator.

I m sorry but there are no beeps or something like that the display doesnt turn on either.

Next time if I can bring this one back to life I think I wont turn the backup battery of

Yes, it doesn't sound like the keyboard is at fault. But, the BIOS is also not completing (because you don't get any beeps). The only simple fix is that you're right and that the backup battery needs to be connected. The "blink of death" is a well known and feared symptom but in your case you are getting some activity. Is the damage to the connector beyond repair? You should be able to have a look by taking out the keyboard.

I took the board out and cleaned it from all parts which are connected, including cpu and so on.

I tried to solder it but my tools were to raw, and my eyes to bad

There are just two thin metal connectors side by side with not more space between them then a peace of paper.

But what do you think: Do I have to lose faith in the mobo to repair it.
And do you think that cpu, fan, display and so on are still in a good condition?

An electronics repair place may be able to advise you on whether or not the damage is repairable. These multilayer boards can be tricky to repair properly. A replacement motherboard may end up costing you about the same - check the Marketplace forum. You should be able to resuse all the other removable parts.

ok, thanks it seems to be the only way to go.
what should be a good price?

Not sure about the market in the US. Your best bet is to place an ad in the Marketplace forum. In OZ, the price for a T22 MB is about $US50 or under (with CPU if you're lucky). Make sure you get a T22 and not a T20 or T21 MB.
