And they said it was on its last legs.

Mi Problema

The button on the old trackpad was dead This is my wife's old macbook pro that the apple store said was on its last legs. I had previously replaced the upper case and battery and everything went well except that %#*@ right speaker cable. I now use the MBP as my main computer

Mi Solución

The repair was simple and your guides are good.

Mi Consejo

Don't believe the Apple reseller. They charged $70 to say the mac was not worth repairing and broke one of the lugs on the old battery as well.
