Laptops :: MacBook Trackpad And Keyboard Not Working After Disassembly
Feb 8, 2010
I disassembled my MacBook to repair a jammed optical drive. I have two problems: the first is while testing that the optical drive now worked (I tested it will it was still partially disassembled, and it did work) I noticed the track pad and keyboard were not functioning. Obviously the power button works, and the machine booted fine, but the trackpad and the keyboard don't work at all. I had to plug a mouse in to move the pointer. I should note that yes, the trackpad cable was indeed firmly plugged in.
However, at one point when trying to reassemble the top case, the trackpad cable detached from the plastic piece that plugs it into the logic board. I removed the plastic piece, slid it back into place over the wires of the cable and then plugged it back in. So I'm wondering if this means I need a new trackpad cable? My second problem is that upon full reassembly, the machine will not turn on. The power button doesn't work when the top case is firmly back in place and the rest of the machine reassembled. I have no idea what might be causing this.
I'm a newbie to this forum and haven't been able to find a solution to my specific problem(s) after searching the archives. I disassembled my 1st generation MacBook to repair a jammed optical drive. Well, now I have two new problems:
The first is while testing my repaired optical drive (I tested it while the laptop was still partially disassembled, and the optical drive does now work) I noticed the track pad and keyboard were not functioning. Obviously the power button works, and the machine booted fine, but the trackpad and the entire keyboard don't work at all. I had to plug a mouse in to move the pointer.

So I'm wondering if this means I now need a new trackpad cable?
The second problem is that upon full reassembly, the machine will not turn on. The power button simply doesn't work when the top case is firmly back in place and the rest of the machine (screws, l-bracket, battery, etc.) is completely reassembled. I have no idea what might be causing this.
So my friend was using his MacBook and went to do something else. He came back and the screen was black, he hit space and nothing, tried the trackpad and nothing. He restarted by holding the Power button, and it go to the log-in screen, but he can't type anything, or use the trackpad. He has tired restarting several times and no luck. He also tried an external Keyboard/Mouse and that didn't work.
He did plug in a Flash drive and the light turned on, so the USB ports are at least getting power, but nothing is working.
Yesterday i was chatting on Adium !! then the keyboard stopped "working" or typing anything the CAPS lock not responding ! tried to use the trackpad but it's not responding too ... i use my MBA every day .. So ... i found out the problem is not with the hardware it's in the software and the only way to solve this is by reinstalling the Osx or something like that ... but how the hell am suppose to run the Osx dvd without clicking the (Alt) or the (c) cuz the keyboard is not working .... ooh ya y usb is still working am typing this from my usb keyboard (yes i tried using it with the installation) but it's not working .
I have a macbook air which trackpad and keyboard doesn't work.
I have searched the forums and tried the most. Here is a list SMC-ResetPRAM-resetCompletely Clean install of 10.9.3 (ongoing)Repaired permissionsChecked if trackpad settings were wrongClose-Open lid to see if that did the trick I have maybe forgotten something, but as you can see I have tried a lot.It all began after the computer being on for over 1 day.When in the login area the OS tells me that no keyboard was found after like 2-3 minutes. Other external devices works just fine. The funny thing is however, the keyboard works when starting up. It's possible to do commands, and if I hold option down to select a start disk the keyboard works here (I can use the arrows to select a startdisc), and when the computer is asleep I can wake it up by pressing the trackpad. So..
Basically I was using my Mac and it froze so I closed the lid. When I opened it again the fan was much louder than normal. It was still frozen and wouldn't respond so I switched it off from the power button. Then I turned it back on, but it wouldn't boot past the grey screen and the fan was still loud. I read some threads here and it said to boot it in safe mode using Shift, I did that and now I'm at the log in screen. However now the keyboard and trackpad aren't responding and the fan is still loud. If I get an external usb mouse and keyboard, any advice on what to do from there?
I have a 2 Gen MBA and today suddenly the keyboard, trackpad and even the USB port stopped working, I tried connect an external mouse but it didn't work, even other USB devices are not working !! I tried the display port it is fine, but I am not sure about the audio port. I tried the SMC reset but it did me no good.
I had bought the MBA from Apple UK but currently I am in INDIA for my winter break from UNI. I don't have my OSX discs at the moment they are back in UK, I tried calling the Applecare but they are closed being a Sunday, and I don't want the local Apple Authorised Service center to touch my air as I don't trust them (The appointment of these repair centers in INDIA is not upto the highest standards !)
The keyboard and the trackpad are working in the Apple hardware test, I was able to move around the cursor and even use the keyboard to select the various options, so I believe the hardware is fine.
So any suggestions what can I do in the meantime, I will call Apple Care in UK tomorrow. I am not back in the UK till the 26th January.
I was just using my Macbook normally and it came up with an error like IP was in use or something with the red exclamation mark. The my internet stopped working so I just restarted it. Now my Macbook is literally not working? I can turn it on but when I get to the login screen, my mouse or keyboard are not working! So all I can do is hold the power button to turn off. It appears OSX is still running fine though because the screen dims after a while and the flashing | in the name input bar is still flashing.
For some reason i purchased this three weeks ago. Everything was working fine. However today i guess i closed the lid and then when i opened it, the computer didn't wake up. So i just held the power button and restarted. It booted into Leopard fine but now the trackpad and keyboard don't work....
The trackpad and keyboard seem to be fine when i hold the option key too choose what volume to boot from. It seems for some reason the keyboard and trackpad lose its function once it boots into leopard.
I looked up forums and tried numerous things like VRAM wipes, SMC reset, tried external keyboard and mouse and they only work up until it actually boots into the leopard OS. Tried going through a hub and same problem.
I bought my Mackbook 8 months ago and I've been very careful with it, I don't use it much and It has never fallen but despite it all when I turned it on a few days ago the keyboard was completely unfunctional and today, when I was hoping it wasn't something permanent I found out that the trackpad isn't working either.
About a month ago my Macbook Pro keyboard and trackpad stopped working when the battery was in the laptop. However, when I take the battery out and keep it plugged into an wall outlet, there are no problems. A USB external mouse/keyboard work fine, but its not easy to bring them everywhere I need my laptop. This may not be relevant, but when the mouse and trackpad are not working, the screen still dims when I place my hands over the speakers. I have bought a new battery, hoping that was the problem, but it made no difference. I can't check to see if my software is updated, because my software update is also functioning incorrectly. It takes an average of 5 hours for the software update to search, and it always comes up with "no available updates."
It seems that during my afternoon class, I shut down my macbook and then when I went to use it about 10 minutes later the keyboard nor the trackpad works. Now the keyboard/trackpad is not defective as it works via the OSX install cd and it works in Windows Vista (dual booted) When ever I start up OSX it just comes up and the mouse is in the upper left hand corner, and the keyboard doesn't work at all. I have tried a pram reset by pressing command + option + p + r and that did nothing. When I am in OSX the only way to get out is to hold down the power button till the macbook turns off. What else could be wrong is there anything I can do, the nearest Apple store is about 80 miles away so I am trying to avoid that at this point as it seems like a software issue.
So recently my keyboard and trackpad stopped working after a restart, none of the keys or the trackpad worked, however, the power button works for some strange reason. I haven't installed any software previous the restart, it's strange why this is happening.
The keyboard and trackpad on my macbook cut out about six months ago and since then I've been using an external keyboard & mouse. I've only just got round to taking my computer in to be looked at at the genius bar, and what I've heard back is that the connections between the logic board and keyboard top section are damaged, and I've got a quote for <$400 for both to be replaced, which is apparently the only solution. The bulk of the cost is the new logic board, and seeing as it's only a connection rather than the processor itself that is damaged, I'm wondering whether it would be possible to have the logic board component repaired or replaced rather than replacing the entire thing.
Sometimes while using computer, the entire keyboard and trackpad suddenly go completely unresponsive and I can't do anything. The only button that works is the power button. It's so annoying because I have to do an emergency shutdown and I hate doing that. Is there any relief?
I got a brand new Macbook Air the other week. I noticed that sometimes, after folding the computer (with the OS running), then unfolding it - the keyboard and trackpad are not responding at the login screen. Actually if I press the keyboard it lights up properly but there is no access to the system. The only thing that works is the power button, so every time I have to power down the computer, then back on again.
I have some strange problem after updating my MacBookPro4,1 to 10.5.7. After a while (can be a few hours) the trackpad and keyboard stop working. When I then put the MBP to sleep and wake it up, both work again but only for about maybe 5-10 minutes. This can be reproduced (put to sleep, works for 5min, put to sleep, works for 5min, etc.) When I reboot it works again for some hours.
It happens randomly. After awhile the keyboard and trackpad stop working entirely. I have to use my might mouse to reset my MBP then it they work fine again.
Ok, after having no problems with my MB pro, I am suddenly having all kinds of problems. Today, my trackpad suddenly stopped working. Finger movements don't work, neither does clicks. Now my keyboard is not fully working. It is kind of 'hit and miss.' I had the MB charged and it was not plugged in. It seems to work if I type very slowly. The only other thing I noticed was that it was really lagging today. The busy pinwheel would come up when there wasn't hardly anything even open.
So it is a macbook pro 4.1 model running leopard 10.5.8. The keyboard and trackpad don't always want to work. I have been using a bluetooth mouse with no problems though. The DVD drive doesn't want to accept a disk, when you put a disk in it keeps trying to read but stops and then wont eject.
It seems that if the computer is on for more then a hour the keyboard and mouse stop working. Sometimes after restarting the keyboard and mouse work again, but sometimes it doesnt. I was wondering if reformatting would help. If so can I reformat by using the DVD drive off a IMac sharing the drive to format the Macbook Pro?
My macbook pro's (late 2008) keyboard and trackpad stopped working about a month ago. I've been trying to get it working again, but to no avail. It initially stopped working when I updated my software. It got stuck on the startup screen after restarting from the install, so I had to hard shut down and restart. When I turned it back on my keyboard and trackpad didn't work.
I restarted again and it worked. Since then it's been going in and out and now it's finally stopped working all together. Since I'm pretty sure it's a software issue I wanted to reformat my computer. Problem is that I can't hold down the option key to boot it from my install disk! And I had to type all this from my usb mouse, and type each key on the keyboard viewer.
I've probably had Bootcamp running for almost a six months and last week I got on my Windows like normal. But to my dismay my trackpad, mouse, and keyboard were not responding. It just seems completely random since I didn't change anything or do anything different. Anyone have any solutions besides reinstalling?
Today I was working with some work and put my laptop to sleep by shutting the lid. Less than half an hour later I opened it and the keyboard and trackpad were both unresponsive. I tried everything but nothing worked so I shutdown the computer by holding the power button down. I then restarted it and they still wouldn't work so I was unable to login. I have also tried an SMC reset but this was to no avail either.
After a few hours of uptime, certain keys on my keyboard stop working and I have to reboot: both command keys and the zero key. Sometimes, after the computer has been in sleep a long time, the keyboard and mouse don't respond at all. I can get the computer to wake up again by pressing the power key, but the mouse and keyboard don't respond, so I can't do anything except hard boot. This problem first appeared after the update to 10.10.1. (I'm dealing with it right now, so I'm getting the '0' through the keyboard viewer, but there's no way to access that from the password screen.)
Info: MacBook Pro (15-inch Early 2008), OS X Yosemite (10.10.1)
I just purchased a 15" MacBookPro (July 2010). I am not used to laptop keyboards so I was able to purchase a bluetooth Apple Keyboard with the Numeric keys. This bluetooth external keyboard was made by Apple and a local company had these brand new for $60. I was told they were the model that came with iMacs. Apple support told me that they should work fine but did not offer an effective solution. So at any rate about 70% of the time this Bluetooth keyboard works great.
But sometimes when you go to type something it starts repeating whatever key you hit so it you were to type and "a" an example the MacBookPro displays "aaaaaaaaaaaaaaa". Sometime just a few of the same character and sometimes it does not stop. I correct this by turning the power switch off on the Apple Bluetooth keyboard and then turn it back on and all is fine, for a while. Sometimes for a week or so then it will do it a lot for a while or just intermittently. The keyboard built into MacBookPro does not do this. I think it may be the Apple Bluetooth keyboard not the MacBookPro or its OS.
I was listening to music on my macbook with headphones one night and once I unplugged them my sound stopped working. There is no red light coming out of the headphone jack and when I go to the sound settings it says there are no output controls. I don't know what to do because everyone says theirs has a red light but mine doesn't.
I recently went out and got myself the 2Ghz macbook w/o the backlit keyboard. I suddenly realized how often i had used the backlit keyboard on my macbook pro 17" that i sold. I got the computer on April 8th and am still under the 14 day return period and was wondering if you guys thought that i could go to apple and return this model for the 2.4ghz model (extra $300)... and if it was worth it....
