Specs: windows me - 2000
I own an IBM Thinkpad i1492 for 10 years. During the Last summer my keyboard keys , are sometimes out of order... there are certain keys of the area (a, z, q, y, h, n, m, j,u ) that Do not apply the character. These keys apply in the same series of the keyboard. Furthermore, sometimes the keys are fine!!! Keyboard, or motherboard replacement?

Might just be a poor connection to the motherboard.

This is What I thought at the beginning, and I tried to connect it once - again... Unfortunately this didn't fix the problem. Furthermore, the problem, appears to be periodic as the keyboard was working fine for several months and now it is faulty again. Also, the fact that the keys that do not function are in the same column, means a kind of keyboard or board lock. I have to say that the keyboard is in a good condition, and I had never spoiled any kind of liquid (as water or tea etc).

It's sure a lot easier and cheaper to try a new keyboard then a motherboard. :-)

Thinkpads are known to have better, longer lasting components than most laptops, but laptop keyboards do not last forever. They are a frequent replacement item and you can get relatively inexpensive new clones of your keyboard on the web. However, you need to determine the right keyboard part number - it's probably on a label on the underside of the keyboard - find yourself a service manual for how to remove the keyboard, and find the part number on the label.

Thank you. I have already found a compatible new IBM thinkpad i 1400 keyboard... All I need to know, is :
1) Is really the keyboard the problem?
2) Is in the new keyboard pack included the wiring tapes(to connect)?
3) Is in the keyboard pack included the trackpoint (tape plus touchpad)?

"I have already found a compatible new IBM thinkpad i 1400 keyboard."

There are many possible keyboards that will fit, but they may not be the same as the one you have now - that's why you should determine the part number of the one you have.

"1) Is really the keyboard the problem?"

If you had a lesser laptop, your keyboard would have been no longer usable years ago. The usual thing is the pads or contacts under the keys just plain get worn out. Typically, the keys you use the most become unreliable first - they may work for a while by you simply pressing the key harder.

I don't know if the keyboard controller is a chip under the keyboard in it's wiring, included with the keyboard, or a chip on the mboard. You could try a known good USB keyboard with your Thinkpad - if it works fine, replacing the built in keyboard will probably cure your problems, and there's probably nothing wrong with the mboard regarding the keyboard.

"2) Is in the new keyboard pack included the wiring tapes(to connect)?"

Probably - usually that's obvious in at least some of the pictures of the replacement on the web.

"3) Is in the keyboard pack included the trackpoint (tape plus touchpad)? "

If whatever your talking about is built into the keyboard, if you search using the right part number, it will have it.

If you mean the touchpad "mouse", that's a separate item, it has it's own part number, it's probably on the bottom of it on a label, it will probably come with whatever cable it needs.
