Hi, I bought my new thinkpad t60p widescreen 15,4 , when comes to me I recognized Two very strange problems, one of them is that sometimes it is a problem with the keyboard when i reinstall it almost all keys works correctly but when I press "k" it shows "\k" and all the time, when I press enter it shows "," and when I press backspace it shows "]" what is it ? I change to the new keyboard and problem is the same.

Welcome to the forum!
See if the keyboard testing utility below tells you anything interesting:

Make sure your region settings match your keyboard. If your operating system is set to a polish keyboard and the system has a usa keyboard layout, you could get unpredictable results.

It is not a problem with keyboard, keyboard is ok, something wrong is with thinkpad... Unfortunately I don't know what, sometimes, it works ok, but almost always it is a problem with some keys....

I also think that's very probable that you have a software issue. It happens me from time to time that I inadvertently hit the left Shift+Alt together and then WinXP will switch the keyboard layout from German to English, so that if I type "Z" it will become a "Y" (among other characters switching positions).
