  • Keyboard track pad freezing

    My keyboard and track pad freeze when no movment is done for about 50 seconds
    but it only does it when it is not connected to the internet or when anything is connected to the usb port I really mean anything (mouse, camera, hard drive)
    After it freezes I can un freeze it by pluging anything into the usb port or close the lid and put the computer to sleep then open it and it will be unfrozen.
    I have tried
    Hardware test (extended and normal no problems found)
    Archive and instal
    Turning off put hard disk to sleep when ever possible
    It's almost like if the computer is doing nothing the track pad and keyboard freeze
    can anyone help

  • Keyboard & track pad have a mind of their own

    My G4 ibook 1.33 had developed a problem with characters moving at random, and the trackpad doing what it wants, when it wants. This is confusing to try and describe but I'll try. Bought this ibook in October 2005.
    When I scroll through a page, it starts to highlight for no reason.
    When moving over a hyperlink, it will click on it without me pressing on the trackpad clicker.
    When signing into my e-mail, it will jump from screen name to password in the middle of my typing the screen name. Very erratic.
    Example:
    The screen name is: [email protected]
    password is: mypassword,
    What happens is that in the middle of typing the screen name, it will jump down to password, and sometimes actually click on the login button.
    It will look like this: Password: johnsm password: [email protected]
    This will also happen when I'm writing a paper, or e-mail. Sometimes my e-mail will be sent before I'm finished. It has a mind of it's own.
    Does not matter if "Ignore accidental trackpad input" is checked or not. I've been keeping my palms off of the area around the track pad while typing lately, thinking that it might be a sensitivity problem, no change though.
    Just had major work done by Apple due to a failing firewire port.: Repair was:
    Product serviced by replacing the following: 630-759, PCBA, MLB, 1.33GHZ, Better, Q72b, NT EEET:43.
    I also described the problem above to the Apple tech before I sent it out, but it's still exists. He mentioned open firmware problem might be present.
    I puchased the ibook in October, 2005
    Ran hardware test from original CD, passed, no problems.
    Software up to date.

    Hi Nyj Shooter,
    Have you tried changing your Trackpad preferences? Try going to System Preferences - Keyboard & Mouse - Trackpad. Try changing your settings around a bit. Under Trackpad Gestures, make sure Clicking, Dragging, and Drag Lock are not checked. Also under Trackpad Options, select Ignore Accidental Trackpad Input.
    I hope that helps,

  • Mac Book Pro Keyboard, Track pad not responding at login page

    URGENT! URGENT! I´m currently in the middle of the amazon shooting a documentary and my Macbook Pro boots up to the login page but I cannot nothing appears on the login line when I type, and my track pad in not responding. Keyboard and track pad dead. However, I can hit the control-apple-power button and get the shutdown-restart-sleep sceen. I plugged in my usb mouse and that works--track pad does not.
    I have rebooted, with power supply, without power supply; removed-replaced battery; still the same problem, boot to login screen--now keyboard, not track pad.
    Any suggestions?

    I also have this problem. After closing my MBP to put it into sleep mode, I opened it a few hours later to resume work and the machine was locked up. I shut the machine down by holding the power key for 5 seconds. Now, every time I try to restart, the login screen appears (after a very long boot time) but the trackpad and keyboard do not respond.
    My summer internship final project is due in 3 days and I am desperate. Please help!

  • MacBook Pro Keyboard / Track Pad issues.

    Help, I am unable to log into my computer, my keyboard and track pad do not respond.
    I had been having problems with an external DVD drive not mounting in 10.5.2. Console would she errors that it would not mount. Under the device manager I would see the drive as usb to IDE with the title of what ever disk I had loaded.
    I read on the board here a possible solution that did match one of the error messages I received about 'IOUSBFamily is unable to enumerate a USB device.' That I should delete the IOUSBFamily.ktext file under /system/libraries/extensions. Along with the kernel cashes file.
    After doing that I restarted my system. Once the MBP loads to the sign in screen I am unable to do any thing else except use the power button to force the computer to turn off. The keyboard and track pad are both unresponsive. However I am able to get the keyboard to respond before the computer starts up, for example resetting the PRAM with holding Command - Option - R - P until the computer chimes again. I am at a complete loss as to where I can go next. I am unable to reinstall OS X at this time or take the computer to a Genius because I am deployed to Iraq. I also would really like to not loss all my data on it.
    Any help is very much appredicated.
    Thank you from Iraq.

    "I am unable to reinstall OS X at this time"
    Why? Because you do not have the System Install DVD with you in Iraq? You really need it to troubleshoot.
    If you have any 3rd party utilites with you like DiskWarrior and/or TechTool Pro, see if you can boot from them.
    I just checked, there are no Apple User Groups in Iraq or Jordan.
    Hopefully, someone else will chime in here with other solutions (if any).

  • A1260 keyboard/track pad on A1226 for multitouch?

    Hi Jim,
    Always good to increase the knowledge base. Thanks for sharing that.

  • Mac Book Pro 15inch i7 - Keyboard and track pad lockup/freeze/stop working

    Hi Everyone,
    I am new to the forum and have bought my first Macbook pro about 2 weeks ago.
    I have been using Macs for years at work but never had my own until now.
    The problem I am facing is a little concerning since the machine is only 2 weeks old.
    When it wakes from sleep, the keyboard or track pad simply dont work, so I am unable to enter my password to gain access to the machine.
    Another strange thing I noticed if I click APPLE and then ABOUT THIS MAC.
    Nothing happens.
    Is there anything I can do to repair this or run a diagnostic of some sort?
    An external wacom tablet plugged in works and a mouse too, but the internal track pad and keyboard does not, on waking from sleep mode.
    Any help and suggestions would be greatly appreciated.
    Thank you
    Bobby

    to anyone looking for a solution to the problem of the Macbook Pro keyboard and trackpad not working freezing or locking up. here is a rather through issue.
    http://gigaom.com/apple/the-curious-case-of-the-missing-macbook-pro-keyboard-and -trackpad/
    After paying nearly £2000 for a machine that is starting to give me problems, I feel like I would rather return it and get my money back, until this problem is addressed.
    With so many people having this problem for over 2 years, Apple has done nothing about it.
    I had the impression Apple was always really quick to respond to hardware flaws.
    Any tips on what I should do? I am still in my 90 day warranty...

  • Mouse, Keyboard and Track pad Freezes

    After upgrade to Lion everytime my iMac goes to 'Sleep', the mouse, keyboard and track pad freezes and cannot wake the computer up. After waking the computer with the power button on the back, these devices still will not response or work. I know there is a option in the Bluetooth system pref. to check 'Allow Bluetooth devices to wake this computer". Make no difference to me when this is checked. Anybody have the same problem as me?

    I'm facing a very similar problem .
    My MBP keyboard freezes eventually during the day - sometimes for a minute, sometimes for much more than that. Mouse continues to work just fine.

  • Random Track Pad/Keyboard Freezes

    Help!!
    I have a white Mac Book that I just purchased last year. All of a sudden I get random track pad and keyboard freezes. Example, just a few minutes ago I went to see if I had any new e-mail. I moved my finger around on the track pad and nothing happened. Now mind you, I could see my scree and my screen saver was still running but the track pad did not do anything. I tried using the space bar, enter, etc. but NOTHING worked. When I hit the power button it pops up with the message did I want to shut down, but of course I couldn't move the cursor to select anything.
    Now, the totally odd thing about all this is that I had my computer at work when this happened - I had a remote mouse/presentation control hooked up. that continued working! So, I thought maybe IT was interfering with the track pad somehow so I unhooked it. The track pad still didn't work.
    I used to SWEAR by Apple products, but I'm starting to think I was wrong. I hope someone can help me out....

    It sounds like you may have had a peripheral (the "remote mouse") that doesn't play well with other devices. Did your system possibly enter sleep while the remote mouse was connected? Furthermore, did you install any third-party software to allow that remote mouse to operate?
    If this problem continues to happen you may have to disconnect any USB-based peripherals that you have attached to your MacBook and see if the problem goes away. Also, if you installed any third-party software to support the remote mouse you may have to uninstall it to get your MacBook working again. If the latter, check to see if the product came with an uninstaller utility.

  • Macbook Pro keyboard and track pad freeze

    I have tried about 15 times now to post this due to the following problem
    Today my keyboard and track pad have suddenly frozen. In appears as if the OS is fine and running but I can't input any kind of key or cursor movement. I have to restart it. Is this common? It's bad news because I have work to do and I can't just get used to using the save command every 30 seconds. That's why I switched to Apple; I was sick of this and similar issues with PCs. Anyone. . . Ideas??

    This happened twice to me in the last five months. I had to take it in for service; the first time, they replaced the keyboard, and the second time, they replaced the entire logic board. The problem hasn't come back so far.
    If you need the computer urgently, it should work if you plug in an external keyboard and mouse. However, I think you'll probably have to take it in for service in order to get the problem fixed.

  • MacBook Pro Keyboard and tracking pad issues

    I bought a refurbed macbook pro from Apple about 10 months ago. I've loved everything about it . . . until now. Yesterday I turned it on and started having keyboard issues. First the y key wouldn't work, then the rest of the keys followed. At that point, it was still starting up normally, but then the tracking pad would only "right click" on items on my desk top, so I couldn't open applications.
    Now it will only open up in safe mode and it makes a noise like I'm pressing all the keys at once at start-up. Nothing happened to it between Saturday night when it was working perfectly and Sunday morning so I'm mystified. I brought it to the genius bar this morning and they also couldn't see what was wrong. Genius said something about how some keys looked "stuck" but mentioned it didn't looked like anything was spilled on it or anything.
    The only "weird" thing about it is that the hing between the screen and the keyboard has always been a little loose but I didn't know until my husband bought a new pro a few months later and I felt the difference. The genius didn't seem to think that would mean anything.
    They told me it would be at least $280 to send it out, diagnose, and fix it. Considering it's less than a year old, I'm a little reluctant (and poor) to do that right way especially since he had no clue what the problem might be.
    I'm planning on trying another Genius Bar to see if they might have a better idea (hey, it worked with my ipod once) but I've been combing the message boards to see if anyone has had a similar issue. I found an older thread that talked about 2008 pros haven't issues with the keyboard and trackpad freezing due to a "faulty pressure connector" so I might try that solution when I get home. But any other ideas would be greatly appreciated! Thanks!

    Welcome to Apple Discussions!
    If you bought your Mac from Apple 10 months ago, it should still be covered by the 1 year warranty and as long as the problem was not caused by accidental damage of some sort, it should be repaired at no cost to you. Was the store aware that you were still under warranty?
    You can even upgrade to 3 year Applecare if you do so before the first year of ownership is up--definitely something to do if your Mac is having troubles already.
    When you see the next genius, make sure they know you are still in the 1 year warranty period, and if you can, upgrade to 3 year Applecare.
    You can also call Applecare on the phone and tell them about these problems and ask them for a case number, which will at least establish that they started while you were still under warranty. If a problem first occurs under warranty, Apple will honor the warranty until the problem is fixed, even if the warranty runs out in the meantime.
    Good luck!

  • MBP keyboard and track pad not working

    Today the keyboard and track pad on our mac book pro laptop just stopped working. The mouse connected to it by usb continued to work but we can't type or anything. We tried the ^F6 keyboard shortcut but it did nothing since of course the keyboard isnt working. And it is also not the number lock key. The computer was working fine all day up until now. It is just under a year old. Any ideas?

    I'm having the same problem. It appeared yesterday and then magically "repaired" itself. My MBP was fine today. Tonight the problem is back. No response from the keyboard and track pad. Track pad works fine using a USB mouse. My problem appears at start up. The cursor is in the usual upper left hand corner. It can't be moved. Restart, sleep then restart do not solve the problem.
    Suggestions?

  • Track Pad Freeze

    I placed an online order from apple.co.nz for a Macbook Pro Core i5 on the 16th of April 2010.
    The Macbook Pro was delivered to me on the 20th April 2010.
    I turned the Macbook Pro on and entered in the required details.
    The Macbook Pro then loaded into MAC OSX.
    I used the Macbook Pro form 5 minutes and found that the trackpad had locked up and was unable to move the mouse or click.
    I rang apple support and the instructed me to turn off the Macbook Pro.
    They told me to hold down a combination of keys to do a hardware reset, and then to turn the Macbook Pro back on.
    The Macbook Pro track pad worked for another 5 minutes and I again rang apple support, again they instructed me to turn the Macbook Pro off and hold down another combination of keys.
    I then turned the Macbook Pro on, and the track pad worked for 5 minutes then failed once again.
    I again rang apple support who know wanted to see if it was a hardware or software problem.
    I was instructed to boot the Macbook Pro from the Mac OSX dvd. The Mac OSX install started and after 5 minutes the trackpad failed again.
    Apple support said it was a hardware fault and that I had to take it to a apple service depot.
    I took the Macbook Pro to the apple service technician on the 21st of April, and they said they would order the parts in and let me know when it would be ready to pick up.
    I waited till the 26th of April and heard nothing from the apple service tech. So I called. He said the part hadn’t arrived yet. Again I had to wait.
    I got a call from the apple service tech on the 27th April saying that Apple had told them that there are no parts available and that I would have to arrange with apple to return the Macbook Pro and arrange a replacement. They said I had to come and pick the Macbook Pro up and organise it all myself.
    So I picked up the Macbook Pro on the 27th April and rang apple. They said that a courier can be scheduled to pick it up on the 29th of April. I said that I will be away on that day and asked if I could drop it into the courier depot. They said that I cannot do this. I asked if they could pick it up on the 28th, again apple said that this was not possible. They said for me to pick a date for pick up so I said the 3rd of May and the apple employee said that it was all booked in, I asked for an expected time for pickup, they said between 8am and 6pm... and that was all they could tell me, and I had to be there to sign something.
    So the 3rd of May was yesterday, I wasted a whole day of waiting for someone to pick the package up, and no one came.
    For starters, the Macbook Pro should have been in full funtioning order when it arrived, and now I have been waiting 2 weeks for something to be done with the defective device. The fact that they are being so slow and difficult when I am just trying to get a working Macbook Pro.
    WHAT CAN I DO!!!!!
    I again contacted apple asking why no one had picked the package up, no answers!
    I now have to wait another 2 days for it to be picked up....

    I have this issue also.
    I have a 2008 MacBook Pro. It's worked flawlessly since but in the last few weeks the trackpad freezes randomly. Only way to get the mouse back is to fold the screen down and reopen. Then everything is fine.
    I'm also running OSX 10.6.3

  • My old MBP (2005) often crashes, freezes or shows grey screen at start up. Also track pad often does not work. I have re fomatted the HD and reinstalled system but to no avail. Genius bar says possible faulty HD, but suspect logic board, any ides any body

    My old 17" MBP (2005) often crashes, freezes or shows grey screen at start up. Also track pad often does not work. I have re fomatted the HD and reinstalled system but to no avail. Genius bar says possible faulty HD, but I suspect logic board. All checks out OK on the Apple Diagnostic bench. Can a Logic board go intermittant?? Any Ideas any body??

    Ive repaired 1000s of laptops over the years (translate: diagnose and replace parts).
    Its not that old, Ive owned 100s of laptops (most were free) ....some I still have are nearly 13 years old and still perfect, ....some extremely expensive ones died in under a year.
    other than becoming obsolete at some point, there isnt really any "will spoil on" data like Milk for solid state computer parts, ....alas.
    You can have a $5000 laptop die in 4 months, and a junker one keep kicking after 10 years.... Ive seen that firsthand countless times.
    Common logic dictates that "very expensive = long life" in computers,..... but all the repair people will tell you just the opposite.
    I know you have a gripe, I get that all too well honestly .
