Keyboard & Trackpad not working but USB are...
Hi - 2007 white Macbook, 10.6.8...
Today the machine appeared to keep freezing completely... after numerous checks (including booting in 10.5), it transpired it was the keyboard and trackpad that weren't responding, not the OS. I know this because I plugged in a USB keyboard/mouse to check and they work fine.
That said, the onboard keyboard & trackpad do work upon boot up for anything from 1 to 10 minutes. Then they just stop responding and I have to resort back to USB again. I can see others who've had similar problems but I can't find a solution.
It doesn't appear to be a fatel hardware error because they will always work on boot up for a limited time. All updates are applied and disc permissions repaired.
Anyone know how to solve this? Appreciate the help - stars all round, thanks.
It doesn't sound like a fatal hardware issue but I think your Top Case Assembly or the connection cable are going bad. The top case is basically the plate containing your keyboard, trackpad, and power button.
The fact that it works via USB basically confirms that, but there is the outside shot that the connector on the Logic Board could be the problem....
Before you take it to an Apple Store, try to boot it up from your software discs that came with your Mac (disc #1, you can do this by restarting your Mac with the disc in and holding down the C key after the startup chime) and see if the problem occurs. If it does, I would have an Apple Service Provider or an Apple Store replace your Top Case for you.If it's okay on the discs, run your Disk Utility on the software disc and reinstall the OS.
I hope this helps!

All of a sudden my keyboard and trackpad don't work on my Macbook. USB keyboards and mice work fine. I took off the keyboard and tried it on another Macbook and it worked fine. Don't know if any recent updates or firmware changes have been done. Any ideas of how to fix or is this a motherboard issue?
Hi today we were having a yard sale. A family member needed to use a computer and used mine. When i got it back from they left in a hurry.
Well I opened it clicked a few things with my "wireless mightymouse" and went to type keyboard did not work so i tried the track pad. So i found this post looking on the web. looked other placess. thought i would shut it down as soon as it went off it immediately turned back on. so i tried again. no luck so i took out the batery unpluged it. Then it would not turn on. Apple is sending a box by monday. I told them i think it is a logicboard="motherboard" problem.
But till then im going to a computer store to obtian my data off my MacBook -
Keyboard/Trackpad not working in BootCamp
I installed Windows XP SP2 on a BootCamp partition, but the keyboard and trackpad on the laptop doesn't work. Only external, USB keyboard/mice work. Any ideas how to get the keyboard and trackpad to work?
After struggling with this for way too many hours last night, here's a trick that finally worked for me. I found it in the support forums of the excellent WinClone utility (which I used to copy my BootCamp partition from my MacPro to my MacBook Pro).
Basically, following these steps to change the Trackpad ALSO fixed the keyboard. I then had to re-install the BootCamp 2.1 update, which gave the function keys back.
Good Luck!

-In device manager notice that in the mouse and pointing devices section there is only the usb mouse that you have hooked up.
-Under Human Interface Devices you have an Apple Trackpad listed change this driver to USB Human Interface Device
-Properties
-Driver (tab)
-Update Driver
-"No, not this time" (radio button)
-Next
-"Install from a list or specific location (Advanced)" (radio button)
-Next
-Dont search, I will choose a driver to install" (radio button)
-Next
-USB Human Interface Device
-Next
-You'll now notice a "Trackpad Enabler" under mouse and keyboard section
-Change the HID device BACK to trackpad driver using the same steps as above- (you will get warnings that the driver isn't "digitally signed" continue anyway and it should then start working. -
My macbook pro 13.3 inch i7 late 2011 edition has previously encountered unresponsive trackpad and keyboard. To solve that, I used to open the back cover and then close it. It has been working fine since that. Yesterday, same thing happened, this time I noticed that bluetooth icon is showing a cross sign across it and keyboard and trackpad were unesponsive. After some time , everything worked fine and bluetooth sign was back to normal. Then , suddenly it went back to the problem. I shut it down by holding the power button. When I booted it again, I could not login because keyboard and trackpad were not working. I attached a HP mouse it didnt work. I opened the back cover disconnected the battery and then connected it again, didnt worked. Since then , I have tried many things and nothing has solved the problem.
@sanjampet
As you suggested I reset the smc, in the first boot nothing worked. In the second boot, it all worked like a charm. I thought that my problem is resolved now. To test it, I shut it down properly. Next morning, I powered it on, all things i.e, keyboard, trackpad, bluetooth etc. worked and I thought that problem has been solved. When I was just going to visit apple forum to reply you, the same problem reappeared. A sawtooth cross over bluetooth icon, keyboard not working, trackpad not working,no usb mouse working which worked well when it was fine. I reset smc so many times again and again but same problem continued. Isn't it a problem of the firmware?
Next time when it will work, I will update its firmware.

My Macbook Pro keyboard and USB keyboard will not work. However, the trackpad and USB mouse will work. Any help?
This is quite frustrating, since it randomly occured as I was browsing the web. It seemed to happen out of nowhere. I cannot login to my user account because I cannot type my password.
Any help will be appreciated.
-MattIf you have another Mac, boot the non-working one into Target Disk Mode (holding down "T" at startup). Hook up the two Macs via a Firewire cable. The non-working one will mount on the other Mac as an external Firewire HD.
Next, download the 10.5.6 Combo update from here:
http://www.apple.com/downloads/macosx/apple/macosx_updates/macosx1056comboupdate .html
Run it. When it asks you for a destination, choose the other Mac that was mounted via Firewire. When it's done, unmount the computer and restart it. The keyboard and mouse should work now. -

Apple USB keyboard does not work with one internal usb port
Hi everyone,
hope someone can help me to solve my problem. I have a MPB13 retina late 2013 since something like 3 months. I have additional screen (dell), usb wired keyboard (apple) and BT magic mouse.
Since a few days, my usb keyboard does not work well. It only want to work properly when plugged to the rights side usb port internal port and not anymore on the left one. It also work on a usb external concentrator. Before, I had no problem, it worked perfectly. There was no problem such as cofee on it...
After searching the web on such problem, I tries a few things such as:
I tried the keyboard on another computer (windows): works fine
I tried usb stick and external DVD reading on the left internal usb ports: works fine
I switch the MPB off and turn it back on: the usb keyboard still does not work on the left usb port
I tried the SMC and PRAM reset : nothing
Any idea ??
Thanks
