MacBook Pro :: Mid-2012 Keyboard Not Working?
Dec 3, 2014
My son's MacBook Pro Mid-2012. Definite signs of liquid spilled on keyboard. Wouldn't start.
Plugged in external keyboard and power supply. Mac came out of safe sleep -- battery discharged. External keyboard works fine. Trackpad works fine.
Computer completely functional, save for most keys dead on internal keyboard.
Powered down. Tried to restart but power key unresponsive.
Installed new keyboard. Computer powered up. Keyboard still messed up in same way -- some keys work, most don't, though power key now does work. External keyboard works fine.
Reset PRAM and SMC. No effect.
Short hardware test showed nothing. Still awaiting results of long test. Backed up all data while I was at it.
My son has a number of shady apps. Torrents, etc. Can imbedded viruses cause keyboard flakiness?

I just bought a new 2012 aluminum Wireless keyboard and the function keys do not work properly. I am currently running OS 1.5.8. I would expect most keys to match the icons on the keyboard. I do not want to upgrade to Snow Leopard or Lion. I have installed an aluminum keyboard upgrade 2.0 and this did not help. I just want the the keyboard functions to match the icons on the keyboard.. Volume up...volume down...

I'm using the macbook pro 2012 retina. The HDMI out to an external monitor works stopped working recently and only works if I'm connected when rebooting. This might have happened after a software update.

I purchased iStat menus for my MBP (no r) mid 2012 and it does not seem to work right. It seems to install ok without any messages popping up but once installed where I get the chosen options onto the menu bar I have a problem. When I click on say CPU or any of the others, a window shows the details but when I then click in that window, at the bottom on EDIT I get a message saying: Tried uninstalling iSta menus and reinstalling but no go.

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.

I'm yet to figure out a pattern, but my Macbook Pro's keyboard will just stop working for several minutes at a time at random points in time...Even if I hit caps or num lock, they don't turn green. Sometimes it'll just happen once every few hours, but I was in class the other day and it would work for a minute, then not work for a few, than work for another minute, etc.

I recently spilled a protein shake over my mb pro. It spilled on the right side, but I quickly cleaned it with a wet tissue and dried it up. The problem, now, is that the illuminated keyboard isn't working..only a few random keys are working and the rest aren't..
What should I do? I have a 1 year warranty left, but I'm not sure it'll be covered.

just came home from Apple Store today with new computer and superdrive, which is not showing up when plugged in. When I put a CD in it reads it for a few seconds then spits it out. I am on the road so getting to an Apple Store will not be easy for the next week.

Yesterday I had a Leopard software update which included new keyboard firmware. I did the update and the keyboard continued to function normally. This AM I booted my MacBook Pro and discovered the keyboard no longer responds to inputs. However, the MB does responds to an external USB keyboard.
Now I don't know if I have a sudden hardware problem or the MB keyboard is not working as a result of the firmware update. Has anyone else experienced a similar problem? Can I go back to the earlier revision of the keyboard firmware?
Hmmm - while writing this I just realized I have a bootable image of my system made a few week back on an external drive - I'll have to try it.

I just got a generic usb keyboard to use with my mbp as schoolwork is taking its toll on the keys and I wouldn't mind preserving it a little better. This keyboard is the dynex from bbuy that's labeled in windows crap but was cheap and works fine on the mac. Unfortunately, everytime the mbp comes out of sleep, the keyboard is unresponsive and i have to set it up again in settings.
Just hoping there's a simple fix and that it's not terminal

I just bought the new 13 inch Macbook Pro. However, at the time the keyboard worked, until I used Migration Assistant and transferred all my data from my old 13 inch plastic Macbook over the network. Now, my mouse works on my macbook, but not my keyboard, so I need to plug an external keyboard to make it work. It also freezes my whole mac if I try typing something into the URL bar on Safari using the internal keyboard.

About ten minutes ago, I noticed that whenever I'd type something, the "y" key would start randomly inputting in the middle of the text. I walked away from the computer to put something away and I saw that the "y" key was pressed multiple times. It looked like this: "So today I went to the yyyyyyyyyy" Soon after, the "m" key started to fail, then the "u", the "j" and now the "7". Sometimes if I press them repeatedly, symbols will come up, or if I press the "m" key, it will type " cxkv." This is a MacBook Pro, the smallest one, bought December of 2011 as a Christmas gift.

My roommate spilled wd 40 on my keyboard and now some of the lights don't work. If I want to fix this issue, what do I have to replace. I searched threads and some people say just the keyboard and some people say keyboard and upper case. So what exactly do I need to replace?

About a month ago, I accidentally spilled water all over my MacBook's keyboard, the mac was turned on, and I notices the keyboard wasn't working correctly; one time before that, I was taking a bath and I had my macbook in the bathroom for music, when I went out and tried to use it, the letter "p" on the keyboard wasn't working correctly, I just turned it off and a couple hours after it was working perfectly!
So I did the same thing this time, let it dry for some hours, and it didn't worked, then let it dry for several days and it still doesn't work! So I removed some keys and try to clean the keyboard with comp air and it didn't worked still. I want to know if there's a way i could log in to my macbook without having to type in the password, like using a remote keyboard or something, please, i love my macbook and i really need to use it for homework! (I study high school and need to record edit, etc music,videos and pics!)

My wife's macbook air (rev. A) just developed this weird problem. She is putting MBA into sleep mode on battery, and the next time when MBA wakes up from sleep mode, the trackpad and keyboard does not work at all. She restarted the MBA and nothing has changed. Luckily the logitech bluetooth mouse and the usb port is still working. We are running OSX leopard dual boot with Vista ultimate 32 bits using bootcamp. But because the "option" key is not working, we don't know how to boot into windows. It is only 8 month old and we have bought the three year apple care. However, she is in China now, I am not sure if the warranty service there is as good.
What do your guys think the problem might be and what should I do about it? She don't have a superdrive with her and if we want to re-install OS, we don't want to lose the windows partition.

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 Pro 15" 2.4 GHz, 3 GB 667, running 10.6.2. Last week my keyboard started acting up, the first thing to go was the "M" key, the key would "work when it wanted to" so to say. This was a little frustrating, but it would come around after typing around the key (on the keys near the M) and I could complete my work. Just one day later the "T" key started to act up at the same time, and shortly after that the entire 5tgb row was working "on and off". I bought a replacement keyboard and carefully installed the keyboard. For 2 days the keyboard worked without a hitch, but now my problem is back, the M key no longer has any issues, however the 5tgb row is starting to work less and less. I want to think this is some sort of connection issue from what I am reading, however it is a "heat" issue as well.
The keyboard will work fine for the first 10 min the computer is on, and then it slowly starts to fade away on me working "on and off" or as it wants to. I have read as much as I could on the internet, however most people I found with problems were due to spilling etc. I have not spilled any liquid on the machine. One thing that I will note is that the motherboard was replaces about 4 months ago by a company that I have had very good luck with, iresq, they had the board replaced because the problem was a known issue with something in the machine, I didn't ask many questions because they got it done for the cost of shipping. Does anyone have any suggestions or has anyone got any idea's for what to test or replace on the machine to get it working correctly? I am at a loss as if it is a connection issue I would believe the mother board would have to be tampered with.

My cat slept on my MacBook last night and now the keyboard isn't working properly ... Some keys don't do anything at all and some keys do things they shouldn't... Any clues on how to fix this? I called the apple support line and we don't think it was anything to do with the settings in 'universal settings'. I'm not sure what else to do and this is one time I do wish I had a man in the house?! Or at least someone else who has half a clue! I rely haven't had many problems with my MacBook 'till now. I'm operating on Mac os x 10.6.8 Also, 2 cats free to good home. Or anyhome, it doesn't even need to be 'good'!

I have a MBP on OS X version 10.6.8, the mid-2009 model. The problem: I can't get my keyboard to light up. When I press on the F5 and F6 button I see the image of the keyboard light pop up on the screen but it has a line through it telling me I can't do it. These feature worked a couple days ago, and I didn't change any settings since then. I have tried everything. I made sure the settings were right and reset them. I have tried to update my software which told me I was up to date. I have put my laptop in a pitch black room. I have covered the sensors. I have done an SMC reset as well as a PRAM reset. None of these things worked. I did download the LabTick app, which then I was able to light up my keyboard but I don't want to have to use a 3rd party application. I would like to have my keyboard adjust automatically. I have uninstalled LabTick.

Earlier I cleaned my Macbook keyboard with a wet wipe, brushed over the keys (pressing them down whilst doing so). Firstly when I went to go back to using my MacBook the trackpad at first decided to use right click only functions, after a bit I managed to get this working fully again. However the keyboard did nothing but work a bit but the keys not doing the functions they were assigned to do. So I rebooted and tried to login but couldn't because the keyboard wasn't functioning resulting in me having to get a USB keyboard to sign in. For a while the caps lock light worked, but now has completely died and doesn't work even when pressed on the USB keyboard. The keyboard is still active as occasionally when I go to try and use it for example a key that doesn't actually control the brightness ends up controlling the brightness?
I've run diagnostic checks and it's all been passed. Absolutely no idea what's going on? If I have to reinstall Lion i'm more than happy to do so but i'd rather not if I don't have to? Perhaps I damaged the keyboard itself when going through all the keys pressing them down? Although it's pretty unlikely the liquid from a wet wipe could get in right?

I'm trying to get the hash key on my UK MacBookPro (Lion 10. 7. 4), unfortunately, the standard alt + 3 keyboard shortcut is not working. Whenever I hold down the combination, nothing happens. The same occurs if I was to press alt + 2-7. Oddly I can get the special characters for alt + 1, 8, 9, and 0. I've tried resetting the keyboard, with no avail. When I use the character viewer, the hashtag is above the 3.

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..

One of the keys on my keyboard are not working. The letter "b" isn't working for me.(I had to copy+paste the letter.) Is there any solution? I restarted my computer and even followed to apple instructions in hopes that it would work. However, the key still doesn't work.
