ibook track pad not working...

[M. Kadioglu]

Hello Group. I  discovered that the ibook I  just bought on eBay 
recently has a defective track pad connector. The connector is not 
soldered on the logic board but completely loose. The unit is past its 
warranty service period and Apple refuses to replace the logic board 
unless I  spend $295. I  went ahead and had the legs soldered on to the 
logic board. Now the connection is like it is supposed to be. However, 
now I  have completely lost the little trackpad action that I  used to 
have... The "System Pereferences-Mouse" control panel no longer 
displays/recognizes that I  have a track pad. I  have checked against 
another ibook, and found the connector to be soldered correctly, and 
the track pad is also not defective as I  was able to install and test 
it on another ibook. So it appears to me that I  have either bad 
soldering, or the logic board/track pad functions are no good, OR.... 
there is some kind of software that I  need to reinstall so that the 
track pad can be recognized. I  am running 10.2.6 at the moment, and do 
not have OS9 on the problem iBook. Any tips would be greatly 
appreciated. Matt.
