Mac freezing mouse and keyboard

What do i do??? Also note i am a total ignorant as far as laptops go so talk to me in intelligible language please!!!!!! Thank you!!! I had the same problem, with my early MacBook Air. I opened it and saw fresh milk. My 2-year old had been watching tinga tinga on it and must have decided that it was a good idea to pour milk down the key board.

In such case, there is only one thing to do, the distilled water trick. You take out the battery. Then you put your mac on a baking tray and rinse it with distilled water - humidity doesn't kill a computer, it's the salts that does or the milk. I repeated five time, submerging the mac every time, then drain and put in the oven at 40 C for 4 hours.

Plug back in the battery, and it's as good as new as is mine that I'm writing on now: Show 13 more comments. Sounds like you're on the right track. Though usually it would take a fall or rather hard jarring of the laptop to dislodge that cable it should be locked down. Another possible cause is battery swelling.

If this Answer is helpful please remember to return and mark it Accepted. There has been no unusual battery behavior. As far as a ribbon becoming loose, the laptop was sitting on my desk all day. I have this issue but with battery swelling, replaced the keyboard though and the cables seem snug and still no connection, any idea?

Of course you've read the other answers here and know about using a USB doesn't have to be Apple or Bluetooth keyboard for inputs. I had keyboard problems after messing about in system preferences trying to gett double click to open files in finder, complete disaster, thought I would have to have new key board as many keys did not operate.

Then I remembered what I had done in preferences: I solved the problem simply by disabling FirveVault. I did the SMC reset while my computer was on - it restarted and gave me several options, one of which was to disable FireVault. I was using an external keyboard due to the fact that my default MacBook Pro keyboard was damaged by water. After choosing to disable FireVault, My external keyboard was brought back to full functionality. I was so happy because i thought i was never going to access all my precious data. FireVault is not compatible with certain computer passwords, that was the issue.

There was absolutely no rhyme or reason why it stopped in the first place; I was literally just in the middle of typing a se. Thank you!!!!! You just saved my life!!! I'm working on my bachelor thesis and I almost got a heart attack when my keypad and trackpad stopped working.

After your help it's finally working: Thanks a lot!!!!! Show 48 more comments. My mothers MacBook Air 13" suddenly became unresponsive with both the keyboard and trackpad. I could get them to work momentarily after a SMC Reset. Then resetting PRAM made it a bit better, to the degree for less than a minute. Obviously not acceptable! The best tools for the whole job were a wired external keyboard and a USB wired or wireless mouse, because they allowed me repair and to orchestrate the process without freezing.

Why is my keyboard/trackpad not working?

Mostly it allowed me to narrow down the problem and the capability of troubleshooting it. As a side note is that this whole problem seemed to clearly be that the MacBook Air was thinking it had Bluetooth keyboard and trackpad peripherals nearby. It's never even been near one in it's life. When I'd look at trackpad in preferences, the onboard settings were gone! This was also the case for the keyboard.

I used my wireless bluetooth Apple keyboard to see if it would even see it. That's when I knew something was up. Usually I try everything before performing an OS restore but nothing would clean it not even an OS restore! But an upgrade and Presto! After all I went through I would recommend a possible fix that could save you lots of time.

It's the reverse engineering of my fix. I didn't try it because the machine is working perfectly after all I did. There's nothing to lose if it works and the process below will likely work if it does not. Personally I think Apple is avoiding admitting to a fix due to a Mud on the Face reaction. I was furious that a 1.

The Power key actually should be working when none of there other keys do. Details for doing so below. Here we go First off, obviously back up all your important files externally using the functionality allowed by the connected keyboard and mouse. So Apple owes me a couple six packs of beer after making me pay them 20 bucks to fix their fault.

Not holding my breath! Personally I think it's a firmware glitch somewhere on that particular hardware that is referred to as the Top Case.

Glad I know the fix so when mine packs up I won't be so terrified! Her's came VERY close to finding the recycling bin. Darn lucky they don't sell cars!!! You are the best thank you so so much. I can't express how freaking frustrated I was trying to type ASDF and thanks to these instructions it worked xoxo thank you!!! Dude, what if the keyboard isn't working at all to begin with?

All the answers did not work. I had to crate an account with Admin rights. Then I had to login with that account, and delete my account. Crate my account again and login with my account. I had to login into my iCloud and get my files back from my backup. This worked for me. Show 2 more comments. I have had this same problem occasionally, but I do believe that most of the posts in this forum are basically the same problem for the most part, that show up in various degrees of seriousness depending on the each machines' individual situation.

Which is why different fixes work for different peoples systems. I would like to say thank you to all the contributors to this forum, because using most of the tips has helped me to solve my systems problem. At least for now ;-. Had no problems at all until the original Factory installed apple battery decided to expand and swell the housing of the keyboard and trackpad.

But the machine is 8 years old. Not sure this is an excuse though. So now I am thinking that this is a hardware problem, that in effect also shows up as a software problem. This is why I believe the whole bluetooth message shows up while booting. I ran diagnostics. Hold down 'D' on keyboard before grey screen shows up. Not sure which versions of Mac OS this still works on, but it worked on mine. Mac OS X Lion The diagnostics came up with an issue.

The error message: Apple Hardware Test has detected an error. Finally i decided, that the problem is on the left side of the machine close to the where the battery ribbon cable plugs in. Because while booting the machine I decided to GENTLY press the cable connectors on the left side and the board itself, which suddenly brought the trackpad back to life. Then when I stopped pressing, the trackpad stopped responding.

Now I'm not sure if any of the circuitry has bad solder joint or a ribbon cable had a broken wire or if a short circuit on the board occurred. I repeated the exercise of pressing the connectors etc in STEP 9 since the problem didn't go away and on the first occasion. This time the Trackpad and Keyboard continued to work.

The complexity of circuit boards today and the amount of heat that is present around that side of the machine could indeed lead to circuits malfunctioning intermittently, which is why some of the solutions that others tried actually worked. In my case the last attempt of pressing the left side of the circuitry and cable connectors has been working for 24 hours.

With that said, does the other possibility still remain? I've had a keyboard problem a year ago while trackpad worked. It's been fixed by apple. What diagnostics did you use? I have this exact problem, my battery apparently is broken and isnt working right. I am bringing it into support now, thanks a lot The MacBook is now hardly one year old, and even if I am a power user, beeing a programmer and all, but this is not supposed to happen Apple!!! Show 4 more comments. Jim Blandford jimb There have been fixes discussed using adhoc materials to fix the issue, but I am not convinced it is an oversight that Apple should have a real fix for.

I am going to spend the day at the closet Apple store in the next few days and will report back. I'm also curious. Also, how is the battery swelling not Apple's fault?

My laptop is having this issue and the fridge method helps but only for a few days. I have never opened my laptop or bashed it on anything. The hardware should be totally fine. The trackpad and keyboard stop responding, and when I restart I get a prompt to connect bluetooth mouse and keyboard. It was working when I was in one meeting room, I closed the lid, I walked to my desk, I opened it, and it didn't respond. I'm in utter despair, after all the hassle I went through getting a replacement, and now it's happening to the new one!?!?!?! Are you sure it's a hardware issue? What OS's are you running on your system?

Also what are you running for apps. A drive that doesn't have much free space can encounter problems depending on what you are doing running. This is helpful in that it corroborates what so many others' stories have suggested. There are several lengthy threads on the Apple support site that run along the same lines.

What is lacking: I totally agree with Sara, Apple should step up to the plate and admit that this is a problem and provide a fix. I have a MacBook Air and always have it powered up, whereas all I have to do is open the lid and everything is there. Then one day in September, I opened the lid and the track pad and keyboard were er-responsive.

I am having this exact issue and am curious what to do I have totally babied this computer and it's only lasted one year!! Haseeb Payab. I have just faced the same problem. Everything was working fine before that. For the past 2 weeks whenever such thing was happening I was just shutting it down and turning it on again and was working. Now this option is not working too.

I am just wandering what has happened as I was taking good care of my system. I believe the only fix is going to replace the track pad ribbon cable. I will let ya know the results. I bought the ribbon cable off Amazon for 4. Emilly Calderon. My brand new MacBook Pro had this same problem, turns out hitting the outside of the keyboard and mousepad works too!

Next time try a hammer! This sounds like you have a loose connection within the USB connector on the logic board. This might be expensive as the connector may need more than replacing. Matthew Ewer. I plug USB devices in. Each time I plug something in or unplug something, it seems like there's a chance for the keyboard and trackpad to become either enabled or disabled. I have been having these issues for weeks and Apple is not helping. They say there are no hardware issues, and to reset my OS. Which helps the issue for about 12 hours until it starts back up again.

If I plug in an external and unplug it, sometimes that works like it just did now and sometimes it doesn't, but that is not a practical solution. I bring my laptop everywhere. Never been dropped, never been squished, only a few scratches on the front because of sitting in a bag. Apple needs to figure this out. I have the same issue here.

But in mine internal keyboard works just the trackpad, it does click and it's not moving. Cable connector on board is damaged with water spill, I cleaned up but no luck. Replaced touchpad and keyboard either not helping. I have MacBook Pro retina. Noticed when computer was operating at temps below 50 degrees everything worked great then as it warmed everything mentioned went wacky.

So swollen battery which cold temp relieves seems to be issue! Bad design cramping battery into the machines. Maybe I jumped to a conclusion it's possible a faulty circuit or bad solder point n not necessary related to battery. Just don't want to blame when it could be battery or entirely something else. I have the same issue my keyboard and trackpad totally disconnected on my MacBook Pro 13". I can get my keyboard and trackpad to work if I press down a few times on the laptop with both hands on either side of the trackpad pretend you're giving it CPR lol , so my only guess is that a ribbon cable is loose somewhere.

It's kind of irritating to do that every couple days because it keeps doing it, but at least I can use my keyboard. Your battery has swollen which is pressing on the keyboard from behind. You need a new battery. OK, have the fix for you and its a simple one! First, I will rundown my issue so there will be no question as to what the issue was! Started off by randomly losing my keypad and trackpak, mayby once a few weeks.

It gradually became worse to every day and having to reboot the Mac to sometimes get it back, sometimes it worked, some times it did not. Eventually i had complete failure. I reformatted my drive and installed a fresh OS, didnt work.

I checked my battery with Coconut to see if it was ok, and it was. I tried the fridge method to see if I had a swollen battery, did not change. Finnaly i decided to order the trackpad ribbon cable, to me it was the only thing that made any sence since it wasnt a software issue, or a hardware issue.

Works great and right away. Saved my self Below is the link if you like! Amazon ribbon cable for Macbook Pro 13" Retina early I use it for movement and all of the sudden my character starting running sideways as if I were pressing it. I was thinking of overheating the battery but I use a cooling fan external which helps a bit.

Temperatures does not seem to be that high, around 60 degree C. Some games are hard on laptops as the heavy graphics cause them to overheat. You may want to use a good tempeture monitoring app like this one: TG Pro. You could have also worn out your E key by over doing it. I would encourage you to use a USB connected keyboard so if you kill it it won't be as costly as replacing the built-in keyboard. I turned it off and put it at a cold place and it came back.
