Trackpad and keyboard not working, tried fix, other suggestions?

Hi there, now as for your latest question. The answer is NO! It's virtually IMPOSSIBLE to test it with a voltmeter that you may already have. Do this instead, attach a wireless mouse and when it shows active then go ahead and enable the keyboard viewer via the system preference pane. From there you should be able to use the keyboard displayer screen and if everything works then you know for a fact that your keyboard connection is defective. The trackpad itself may also be defective as well, you should use your installation disk to run the "Utility hardware test" and let the machine find the problem for you. Chances are, you need to replace the trackpad alone provided that your keyboard cable has not been compromised in ANY way (nor has the keyboard itself been exposed to any type of a liquid spill). Do understand this, the answers you see are solely depended upon the accuracy of the problem being explained/reported.

"Congratulations on getting the keyboard working by replacing the flex cable. I'm going thru a rough period where I've had 3 different Macbooks with keyboard/trackpad problems. I replaced 2 entire top cases (2007 Macbooks) and the problem went away, but now it's come back on one of the Macbooks.

Power button works, but keyboard and trackpad don't work once computer has booted.

With the 3rd Macbook, from 2008, it's a slightly different problem: the power button works and the Macbook boots fine, but the keyboard and trackpad don't work; external USB and Bluetooth keyboards and mice work. I thought it was a bad keyboard, but the keyboard from this Macbook works on another Macbook; and a working keyboard doesn't work on this Macbook.

So it looks like the Macbook has some problems re. the connection to the logic board. Do you think?

Any ideas greatly appreciated.

I've taken lots of Mac portables apart over the years, but these Macbooks seem to have very fragile keyboard connectors, whether it's the flex cable or the connector on the logic board.

How hard is it to replace the keyboard flex cable?

Where can you get instructions and/or video? Doesn't seem like they have it here - just the entire top case replacement.

I have a 2007 Macbook keyboard that I use when I have to replace keys. It suffered water damage, but all the keys have worked, so I don't know how badly it was damaged. If I could, I'd like to try the flex cable from this keyboard to try to repair the other one. If not, I'd try to find one or two on eBay."

"can anyone confirm that this is the correct part to fix this?

"That is the part that I used to fix mine. I was really happy with everything from the company too, I got the part fast.

best of luck."

"My keyboard and pad stopped working after hooking up the portable to my large monitor and external keyboard - not the first time, been doing this for years with THIS computer -

anyway, I just took out the battery for a couple of seconds, placed it back in, and it's now working fine!!"
