    Yes i have restart my computer but i havent thought to reboot it and then plug it back in
    *update* i just tried it and something came up saying there was no keyboard plugged in, when i plugged the keboard in my mac recognised it but i still cant type.
    Also i have tried using it on the current computer i'm typing on (also a mac) but the keyboard is still unresponsive.
    To make clearer my situation i was wiping the ketboard down while the mac was on. i then turned it restarted it and switched user acounts. i was typing in a forum when i noticed that i couldn't type certain letters and pressing n key also made my mac type m
    ex. i type the word can and comes out as canm
    thats when i tried restarting again, problem is when i tried to log back in none of the letters required for my password worked and soon none of the keys on my mac functioned at all.

    well i currently am sick with what could be the flu and there are other people in my house who use the computer as well, so i wiped it down with a disinfectant wipe, i usually use these wipes to disinfect the keyboard but i usually unplug it before wiping to prevent this kind of problem.

    this feels abit stupid to ask for, but have you shut down your computer and turned it back on?

    and since its a usb keyboard, have you tried it on either another computer or tried to boot your computer without the keyboard and then connect it when the mac is fully booted?

Im sorry to tell you that most likely you have gotten some sort of fluid down into the keyboard wich has shortcircuited it.

Why did you wipe it in the first place? did you try to remove something you spilled? or was the cloth you wiped with wet?

When i type on my macbook Air keyboard I only get special symbols but when I plug in a USB keyboard it works fine. I also noted that when I restart it, It asks me to chose the startup disk? Please help!!

From your description it sounds like your alt key on your keyboard is sticking. Try tapping it a few times to get it moving, or get a can of compressed air and blow it around the sides of the keys. If your Macbook Air is still under warranty or is under AppleCare arrange an appointment with your local Apple Store and have it repaired professionally. Hope this helps.

Some of the keys won't work and I can't log in Please help I have homework

If your keyboard has a key marked "NUM LOCK," make sure it is not enabled. This is a common cause of some of the keyboard keys not being recognized.
Not being able to inspect your machine personally, the only other option I can suggest in time for you to get your homework done tonight is to attach a separate USB keyboard to your MacBook and use it. It will work just fine, provided your problem is in the original keyboard and not in software. You may be able to borrow a USB keyboard from another computer in your house, or from a neighbor. It need not be an Apple keyboard.

How do i unlock my mac laptop keyborad

There is no keyboard locking facility on the Macintosh.
I suggest you attach an external USB keyboard to your Mac and see if it works. If so, your builtin keyboard may need repair. If not, you will have to be more specific as to what behavior you are receiving from your keyboard, and what state your machine is in when it occurs.

MacBook locked up, won?t close down

The first thing to try is this: It is a keyboard shortcut to shut down a mac laptop. Press the control key (ctrl) at the bottom and press the eject button at the same time (top button all the way to the right which looks like an arrow pointing up with a line under it). This should bring up a window asking if you want to restart, sleep,cancel or shut down. Click Yes to shutdown! If this does not work, here is the second option. Press the power button down on the upper right side,and just hold it down until the computor turns off. I have done this many times with my own computor when it has crashed with no ill effects, I have heard from Apple that it is not good for your computor and can cause problems, so I would only do this if the keyboard short cut does not work Good luck and if you find this helpful please comment!.

Hi - I have a macbook and seem to have locked the keyboard - if I plug a mouse in at the USB it works but the mouse on the macbook isn't responded, nor are any of the other keys - is there a simple...

Hello sarahscarah,

I've repaired a fair share of Macbooks with the same issue, but just to make sure it is what I think it is I'll need you to do a few things.

This issue is thought to be caused by a bent/warped ribbon cable that is located under the battery. This cable is what connects the trackpad and keyboard to the rest of your computer. To test if this is the problem do the following.

  1. Verify that an external keyboard and mouse will work with your Macbook when plugged in to a USB port.
  2. Connect your Macbook to your power adapter and plug into wall.
  3. Unlock your battery by turning the dial on the bottom of your Macbook with a coin.
  4. Remove the battery and set it aside.
  5. Press down on the exposed trackpad cable with your finger.
  6. While pressing down on this cable try typing on your Macbook's keyboard and moving the cursor with the trackpad.

If this works then you've solved it, you can place a piece of "Kapton Tape" over this cable to hold it down, but this is a temporary fix. You will probably need your trackpad and keyboard replaced. If your macbook is still under warranty take it to an Apple store, show them the problem and have it fixed or replaced. If its out of warranty you'll be looking at a $200-$300 repair to have the trackpad/keyboard replaced by a technician.

Here's a picture of the exposed trackpad cable for reference.

Hope this helps, if so please leave positive feedback. Thank you.

Keyboard on my MacBook laptop works intermittently. I re-installed OS X but that didn't fix it. Do I need to replace the keyboard?

It's possible you just have a loose cable.
Find any USB keyboard. Plug it into a USB port on your MacBook and use it. If you can use this keyboard and it doesn't fail intermittently, it's a hardware problem in your on-board keyboard or cable, not a software problem.

If it's a hardware problem, you're going to need to find someone who can open up your laptop and fix it, especially if it's under warranty.

Wiping a Macbook clean like NEW

You need the original Mac OS recovery cds to initialize the hard drive and reinstall the software. Aplle calls formatting the hard drive- Initializing the hard drive. If you don't have the cds, then you need to purchase the Mac OS cds. either Tiger or Panther (again, that is what Apple calls it's software)

If the unit still boots up but is having issues, you can click on the hard drive icon. , click on Applications. Click on Disk Utility.
Click on repair. The OS will repair any errors that it finds. If this works, great. If not you will have to use the Mac OS cds.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

I’m happy to assist further over the phone at
