Keyboard and Trackpad Not Working, Power Button works good.
MacBook a1181 keyboard and trackpad is not working at all. First, the trackpad stops working then after several days the keyboard also stops working without any ideas what cause them to stop working. macbook works fine with USB keyboard and a mouse. I order the "UPPER CASE with KEYBOARD" here at iFixIt. When i received the keyboard i immediately replaced my uppercase.... but still keyboard and trackpad is not working.. What specific parts in the logic boards (chips which control the uppercase) to check or inspect?? is the problem repairable?? i need help.
Update
Macbook 13" 2.0Ghz Black/Penryn...... i'll post the serial number later.. i order uppercase with keyboard with part number 186-044-3.
Update
the last three figure of the serial number is 0P2 and the part number for the uppercase i ordered is 186-044-3.
Is this a good question?

Are your symptoms exact the same with the new uppercase? Would you give us the last three figures of your serial number and the part number of the uppercase you ordered? Thanks

@ nicksmacan and Charles, thanks for the suggestions... i will try your suggestion and let anyone if this solve the problem...
STEPS that have been done prior to the problem but it does not solve the problem;
1.) SMC and PRAM reset. disconnect battery and hold power button for more than 5 secs. hold down CMD-OPT-P-R before powering ON for 4 consecutive restart.
2.) updates MAC OS X to latest 10.6.8 using USB keyboard and mouse.
3.) reinstalling MAC OS X with new HDD using USB keyboard and mouse as well.
4.) tear down the macbook. taking out the logic board from the case. cleaning thouroughly the logic board, inspect possible marking of defective electronic component such as sign of burn, reheating the logic board using hot air especially the surrounding the connector of the logic board to the uppercase.
5.) planning to try the suggestion of nicksmacan and Charles.. immediately give you response after doing their suggestion.

Today I have the same problems - even external keybard/mouse do not work. Just the power button works fine.
Did you solve the problem already?
Thanks
