The bottom half of my trackpad stopped responding to touches.

The bottom half of my trackpad stopped responding to touch.  The button still works fine, a USB mouse works fine, and the top half of the trackpad works fine.  Any ideas of what the problem could be?

I have the same problem.  My clicking works but I cannot drag.

  • Magic trackpad stops responding on wakeup after upgrade to Mavericks

    I have a 27" iMac purchased in July 2011.  I never had any issues with the trackpad before upgrading to Mavericks.  I upgraded a few months ago and started having sporadic issues with the trackpad.  When the iMac woke up, everything seemed fine at first.  About once or twice a week, after it had been working for about a minute (just enough time to start web browsing), the trackpad would suddenly stop responding.  It then progressed to being more consistent (every other day).  The cursor was still visible and the keyboard still worked.  The trackpad was still on but apparently not connected.  I thought it was the batteries, but new batteries didn't help.  I could get the trackpad to work again by using Spotlight to open the Bluetooth System Preferences.  The trackpad worked immediately when Bluetooth preferences were opened (nothing needed to be changed; it would just start working).  However, it would stop responding after about ten minutes.  It was interesting because even if I left the Bluetooth System Preferences open, it would still stop responding after about ten minutes.  I could use the keyboard to make the preferences window active and it would immediately work again.  It would then work again for a few minutes and then stop.  I found that removing the trackpad and re-connecting it would cause the trackpad to start working again more consistently.  It would only stop if the iMac went back to sleep for an extended period (overnight). 
    For anyone else with this problem, helpful keyboard shortcuts are cmd + spacebar to open Spotlight, type bluetooth, use the arrow keys to go to Bluetooth system preferences (hit enter), use the arrow keys to go down to the trackpad, press spacebar to unconnect, again to confirm, and then after the trackpad is automatically rediscovered, press spacebar again to pair it.
    This went on for about a month, when I had what I suspect was an unrelated problem.  The trackpad started acting as if it was being held down (left click was always being pressed).  I took it into the Apple Store and they confirmed it was broken.  I was a little disappointed since it had basically expired about a week after my AppleCare expired, but luckily the folks at Apple took care of me.  (Thanks Apple!).  At that point I had a brand new trackpad. 
    The issue had gone back to happening every other week or so.  I thought it might be interference, but I've since physically moved apartments and all the objects around it. It's been a couple months now and it's back to happening every couple of days or so.  Since the trackpad is brand new, I have to think this is a software issue.  I've noticed the following consistently:
    1) It only stops responding if I've put it to sleep (I usually do so with a hot corner, but I don't have any reason to believe that's related) and haven't used the computer for more than 12 hours.
    2) It'll always work right when it wakes up.  It'll stop fairly consistently 1 - 2 minutes after waking up.
    3) Time Machine seems to be busy doing something when the trackpad stops (the little icon is spinning in a circle if I have a Finder window open).  Uncertain if it's always doing something or if it's coincidence that I've noticed it more recently.
    4) As mentioned above, opening the Bluetooth System Preferences will always get the trackpad to respond, but then it'll stop after a few minutes.  Unpairing and reestablishing the pairing will fix the issue for awhile (at the very least until the next time the iMac sleeps).
    5) I may be imagining this, but before upgrading to Mavericks, I think it used to show the message that the trackpad was connected when the iMac woke up.  I no longer see that message unless I remove the connection and setup the pairing again.
    I've seen lots of people with various issues with Bluetooth connectivity and Mavericks.  I'm on 10.9.4.  No one seems to have exactly this issue.  If anyone has any suggestions, I'd appreciate them.
    Thanks!

    Please read this whole message before doing anything.
    This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
    Step 1
    The purpose of this step is to determine whether the problem is localized to your user account.
    Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
    While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
    Test while logged in as Guest. Same problem?
    After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
    *Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
    Step 2
    The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
    Please take this step regardless of the results of Step 1.
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
    Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    Test while in safe mode. Same problem?
    After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

  • I recently bought a new PC and when I transferred my photos a number of them became distorted- the top half was ok but the bottom half were color shifted.  Also a number of them the top and bottom don't line up.  How can I fix this?

    I recently bought a new PC and when I transferred my photos a number of them became distorted- the top half was ok but the bottom half were color shifted.  Also a number of them the top and bottom don't line up.  How can I fix this?

    Hi, I see I haven't had any responses but these problems haven't been fixed.
    I still haven't been able to transfer purchases from my phone to my comp so consequently have stopped purchasing on my phone.
    I bought a couple of albums recently via itunes on my comp, and tried to tranfer them to my phone via a playlist, but the sync often crashes. One album transferred except for one song, and the other hasn't at all. What happens is that when I autofill from a playlist it often hangs for ages on the first song and then I have to quit the application altogether as nothing happens for ages. Basically, the whole Itunes software freezes. 
    After this I find it hasn't transferred any songs, but they do appear greyed out on my phone, which means it has transferred some basic data such as the titles, but not the song itself. When I try to repeat the process to complete the transfer Itunes tells me that it can't transfer because the songs are already on the phone, but they are not!! I can't click or remove on the greyed out items, so now I have a couple of almost full albums on my computer that I can't tranfer or install on my phone, and a whole bunch of greyed out songs on my phone that I can't play or remove!
    The rest of the problems as above still stand. I downloaded the latest itunes OS updates but nothing's changed. I haven't done the very latest iphone update yet though because it says you need to make sure your stuff is backed up, and I don't want to lose the purchases I made on the phone that I can't transfer to my comp. I'm planning on uninstalling itunes completely and reinstalling but I have little faith that this will fix the issue.
    Can someone please help at all?? I'm so sick of this!

    Apple also offers an out of warranty or not covered under the warranty "repair", which pays for an exchange at a discounted price.

  • :( The bottom half of my iPod is now fully blank :(

    Yeah. It was in my pocket but when I drew it out, there it is. The bottom half of the screen is gone, but everything else works absolutely fine. What am i gonna do now?

    I had the same problem. The bottom half of my screen was illuminated, but blank. When I turned the nano on, a hazy barcode looking image (hence my screen name) appeared in the bottom half of the screen. Then it turned blank. Everything else worked.
    Only yesterday, I took my nano to Apple's store in Soho (that's downtown Manhattan) and exchanged it for a new one. No argument. No discussion of a warranty. Just polite, friendly service. A word of advice. Apple's "Geniuses', as they are styled, require "appointments". You can sign up online at home. When you arrive, you must sign in and wait to be called. I didn't have an appointment, so I made one. Fortunately, it was for only one hour later. I appeared at the appointed time, had to wait around 30 to 40 minutes, and then received friendly, professional service. The brand new nano was exchanged for my old one, right then and there.
    Another word of advice: Refer to the problem as a "screen anomaly". I read a message from another poster who telephoned Apple tech support and spoke with several tech reps. They referred to the problem as a screen anomaly. It may help. Good luck.

  • Why did my Firefox window minimise to half size, with the bottom half of the screen showing the window underneath the Firefox one?

    Today the bottom half of my Firefox browser window just drew up to the halfway point on my screen, and will not maximise again. I tried taking Windows back to a point 2 days ago, but the problem remains.

    Not sure what happened, but the problem disappeared by itself.

  • Touchs creen on the bottom half not working

    i have a strange probglem on my phone and the bottom half of the screen wont work and the top half will, i cant answer any phone calls i cant open the ipod or anything on the bottom i wish i had put them on the top rows now and the top rows will move about so i can turn it off but the moment i lock my phone the only way i can access it again is if it tiurn it off and on again, thank god the turn off thing is on the top lol, its a stupid problem to have but has anyone ever had somehing like this? could it be solved with a restore? this would be a great time for the springboard to be able to switch sides. maybe 3.0 will fix it?

    thanks for your replies, its good to know im not the only one who has had or having this problem.
    i will try a restore, im trying to avoid this because i have app store apps i dont have saved in itunes after i had to format.. but if it makes my iphone work its definatly worth trying.
    i think its still under worranty if the restore does not work putting to dfu mode and restore, ill take to store see if they can replace it. but hopefully by then ill be able to buy a new iphone maybe get the 16gb..
    thanks will post results if it works

  • I have read all of the discussions about headset echos, my echos are heard by the caller when i hold the phone by the bottom half. The echo disappears  when I change my hold position.  Anybody else having this problem? Fix?

    Don't hold it like that. You're creating an 'echo chamber' due to the position of your hand/neck/face. It's not a technical issue. I hear this when I talk to my wife and she cradles the phone against her shoulder.

  • On the top left of my computer screen there are what look like the bottom half of small grey and white squares stacked on top of each other. They form a line about three inches long and I cant seem to get rid of them.  Is my computer dying or being hacked

    On the top left of my computer screen there are what look like the bottom half of small grey and white squares stacked on top of each other. They form a line about three inches horizontally along the top and they cover half of the regualr bar (so half of the apple sign int he corner is covered) and I cant seem to get rid of them.  Is my hardrive crashing or being hacked?

    I have never seen DEVELOP on the menu bar for Safari, hence my query regarding testing. 
    What OS are you using and what version of Safari?
    If you want to check your HDD, Open Disk Utilities>First Aid and run Verify and Repair.
    The only remedy that I can think of that may work is an OS reinstall.
    I seriously doubt that your MBP is being hacked.

  • Help! I have a flickering white screen but I can still turn on my IPod Touch! It is a white flickering but the bottom half of the screen is unseeable. How do I fix it?

    Help! I have a flickering white screen but I can still turn on my IPod Touch! It is a white flickering but the bottom half of the screen is unseeable. How do I fix it?

    Try the follwing to rule out a software problem:
    - Reset. Nothing will be lost.
    Reset iPod touch:  Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Restore from backup
    - Restore to factory defaults/new iPod
    If you still have a problem then you likely have a hardware problem and an appointment at the Genius Bar of an Apple store is in order.
