T440s: computations and trackpad

Hi guys,
Four quick questions for you regarding t440s, which hopefully will help me decide if to buy this model:
1. In your experience, can you do computations on this ultrabook (assuming 12GB)? e.g. Eclipse, Visual Studio, Matlab, etc.
2. Trackpad sound when pressing it down: how bad is it actually? Can you tap on the trackpad, without pressing it down, similar to Mac? 
3. How would you rate t440s trackpad compared to Mac?
4. Most reviews seem to refer to a Windows configuration. How would that change for linux?
Thanks!

I will answer this one:
2a. Trackpad sound when pressing it down: how bad is it actually?
It is louder than I would prefer, but it is not uncomfortable.  If I was in a room with several other people using the same trackpad, it might get annoying.
My trackpad was defective to begin with - it was very loud.  I had it replaced and now it is more tolerable.
2b. Can you tap on the trackpad, without pressing it down, similar to Mac?
Yes you can just tap your finger without pressing it down.  And you can tap two fingers apart to trigger a right click.

  • Keyboard and trackpad unresponsive after computer is woken from sleep or battery runs out

    I am having problems after my battery runs out completely or when I open my macbook  a day later with the battery charged. If my battery runs out, after I plug it in and turn it on, the first thing that appears is the login page and there is a dark grey background instead of my normal blurred background, and the user picture is shifted to the right. After I enter my password a small white bar at the bottom loads and my normal login page loads, but this time my keyboard and trackpad are unresponsive. I have to wait for the display to go to sleep, close my macbook and then open it for my keyboard and trackpad to work. Sometimes I have to repeat this process more than once. The same thing happens when I wake up my computer with full battery after a nights sleep, and instead of being able to wake it up just by opening the lid I have to turn it on with the power button. Please help I know this isn't normal behavior. I have already reset the SMC and PRAM with no success and this problem was there before and after I upgraded from Mavericks to Yosemite.
    Thanks

    if any one ever has this problem, i figured it out. you have to reset the PRAM AND NVRAM. to do so...
    hold down the command+option+P+R keys before starting the computer and wait for 2 start up tones. done and done.

  • Keyboard and trackpad freeze and randomly become unresponsive

    I've got a MacBook Pro (15-inch Early 2011) running Mac OS X 10.8.2.
    Since a few weeks ago at random intervals my keyboard and trackpad become permanently unresponsive. I don't recall any particular cause or change that would have caused this to start happening.
    What happens is that the trackpad and keyboard will stop functioning completely. The computer, display etc. would continue to function properly:
    The clock keeps ticking.
    If music were playing it would continue etc.
    Internet connectivity (via an ethernet cable or WiFi) continues to work as well (a download will continue, and even resume if I disconnect and reconnect the ethernet cable).
    Presssing the power button will bring up the shutdown dialog as usual (but I can't use it, obviously, so a forced shutdown needs to be performed instead by holding down the power button longer).
    .. but the keyboard and trackpad are rendered inoperable, as if they were no longer connected.
    I've made no progress in finding out what could possibly be the cause of this. A few observations:
    It has never happened while not using the keyboard (e.g. watch a DVD with TV series for a few hours, and afterwards the keyboard would always be fine).
    It always happens while actively typing (e.g. while in the middle of replying to an e-mail).
    It is not a temporary problem, the keyboard and trackpad will not become responsive again after some time (the computer isn't particulary occupied with calculating something big, no beachball and no busy mechanical noises).
    It does not happen progessively. It works fine and snappy one second, and I'm touching a dead keyboard a split second later.
    I tried connecting a USB keyboard but that doesn't seem to work either (I'm mentioning this since some of the linked threads below close with that as a solution).
    Possibly related (although I haven't found anything in these threads):
    Keyboard causes trackpad to not function properly
    Keyboard and trackpack freeze
    Keyboard and Trackpad Unresponsive
    MacBook Pro Keyboard & TrackPad freeze! Totally Unresponsive!
    MacBook Pro inbuilt Keyboard and Trackpad freeze when not connected to bluetooth devices?
    I've crawled through some log files in /var/log (via the shell and through Console.app) and found a couple things that may be relevant, although they seem unrelated. Etiher way, I was surprised by what I found. All sorts of errors with regards to Bluetooth and USB stuff. I'm not aware of using either. I haven't used bluetooth in years and though I sometimes charge an iPod by USB, I haven't had any problems with that, and this keyboard/trackpad freeze has also happened on sessions where I started the laptop and never even touch the USB ports in the time leading up to the freeze.
    Sample log from when it happened. It last happened at 21:04:xx:

  • Mid 2011 Macbook Air - Yosemite keyboard and trackpad stopped working, the only button that worked was the power button, only one USB port works.

    I have a Mid 2011 Macbook Air.
    Upgraded to Yosemite last week.
    Three days ago I was using my Macbook Air for the first time since upgrading to Yosemite. I had been using my Macbook Air for approximately 30 minutes, I was using safari and the keyboard and trackpad stopped working (would not respond). The only button that worked was the power button.
    I rebooted and they were still not working. I plugged in a USB mouse and external USB keyboard, only one USB port would work (the Left USB port if looking at the screen) so I had to swap between keyboard and mouse.
    After logging in there is a bluetooth icon at the top of the screen with a sawtooth line through it. Bluetooth is unavailable and the bluetooth icon is missing from the system preferences menu.
    If I run a hardware test by holding D (on USB keyboard) at startup it says that no problems are found and at the conclusion of the test the keyboard and trackpad start working again. When I log on the bluetooth is working again.
    I shut down the Macbook Air and when I started it again the keyboard and trackpad and right side USB ports were all not working again. I logged in using the USB keyboard and mouse and the bluetooth not available sawtooth icon had returned.
    I ran the hardware test again and at the conclusion of the test the trackpad and keyboard started working again.
    I have tried deleting com.apple.Bluetooth.plist and com.apple.Bluetooth.plist.lockfile from /Library/Preferences/ and tried resetting SMC and Power Functions but this did not fix the issue. The only thing that seems to work is running a hardware test - obviously I don't want to do this every time I use the computer.
    I do not believe any hardware is faulty/damaged - I think it has something to do with bluetooth/Yosemite.
    I do not have the Macbook with me at the moment, if you have suggestions that I can try or additional checks/info you require please let me know and I can get back to you.
    Thanks,
    John

    Hi!
    I have exactly the same problem, and I can't find any solution.
    I can't even track down the root of the problem: the Bluetooth/Wifi module? The trackpad? The keyboard/top case? The logicboard?
    I've tried all the usual: SMC/PRAM reset, clean install, kext cache clearing.
    Any suggestion is greatly appreciated!

  • Keyboard and trackpad stop responding briefly

    I have a late 2012 (current generation) MacBook Air with all software up to date.
    Every so often (sometimes multiple times per day, sometimes not at all) my keyboard and trackpad will stop responding to input for 1-10 seconds.
    This has been happening since the computer was new.
    Every time I go to the Console after I regain control I see the following:
    [date] [time] Dock[processID]: no information back from LS about running process
    There does not seem to be any prerequisite to that line, sometimes it's the only output written in the last 30 seconds.
    Does anyone have any idea what's going on here?

    If this were happening to me I would suspect a third party software conflict.

  • Trackpad and trackpad button often unresponsive in Mavericks

    This is an offshoot of discussion about a mouse right click not always working since upgrading to Mavericks.
    I said using the trackpad and trackpad button on my MBP often doesn't effect the computer; I have to repeat those actions multiple times before anything happens.
    Drew Reece offered some suggestions for my issues:
    First, I came to Mavericks from Snow Leopard because I'd tried Lion and Mt. Lion but found my old laptop (early 2008 MBP v4.1) ran way, too slow.
    Before going whole hog on Mavericks I read a lot, then installed it on an external drive (spinning, connected with FW800) and played with it for a few days.  I used Migration Assistant to make the move, which segregated software that was not compatible.  Mavericks was slow for a few days, but did gradually speed up.   However, that was when I first ran into the issue with the trackpad and button not registering with the computer's display.  I also ran into the problems with Mail not liking my 3 Gmail accounts but actually solved that using by booting in safe mode, thanks to another poster here.  Not sure why - I attributed it to Spotlight indexing the drive - everything about the computer was very slow and extremely funky while in safe mode; no way I would want to judge the OS based on performance during that boot.  It was awful.
    I did update a lot of applications to Mavericks-ready versions while I was using 10.9 on that external drive.
    When I felt comfortable, I wiped my NBP hard drive and did a clean install of Mavericks, followed by repeating the same software updates.  Then used Super Duper to just bring over User folders from that external drive.  Because SD restores the Spotlight state there was no "break-in" period so Mavericks ran reasonably fast right away.  I wasn't ready for iCloud deleting my Address Book data but, fortunately, I replaced everything from the external drive's Users/me/Library/Application Support/Address Book folder.
    So, per Drew's suggestion, I ran EtreCheck:

    I don't see anything that mentions software - good or bad.  And I don't see anything else that indicates a problem but maybe I just don't know how to read this report?
    Sorry about the length of this but I wanted to addres all Drew's suggestions.  And I'm still seeing those intermittent trackpad/button issues.
    - thanks

    I'll try to break down each of these sections & point out any bad signs below.
    Hopefully the color helps…

    Red items are loaded at the system level
    Blue items are loaded at the user level
    The other stuff gets loaded into apps like Safari - they are internet plugins.
    Cleanup:
    All the usual caveats apply, backup before you modify the system, delete the items (or move them to another disk or folder if you are worried about deleting the wrong thing) but ensure the originals are gone or updated.
    Use the Finders "Go menu > Go to Folder…" to open the hidden ~/Library (your users library).
    Reboot for the system changes to take effect.
    How to find updates:
    The critical launchd jobs & kernel extensions use reverse domain notation e.g.
    at.obdev.littlesnitchd.plist means look at http://obdev.at for 'LittleSnitch' updates
    You want to try to update or remove all the system level items.
    Startup Items: Stored in /Library/StartupItems/
    Startup Items have been discontinued by Apple since Mac OS 10.4. They are responsible for making changes at a system level. Remove them all or spend time ensuring ALL related software is up to date. You need a very good reason to have anything installed in here.
    Kernel Extensions: Stored in /Library/Extensions/
    Kernel Extensions also load third party code, but they insert it into the 'core' of the OS. These can be safe, however you must ensure the related tools or apps are up to date, otherwise the system is basically built upon quicksand. Remove them all & see if the OS works better.
    Your LittleSnitch is out of date for example, how about hardware monitor or Rogueamoeba's software?
    Launchd jobs: several types
    LaunchAgents          - Stored in /Library/LaunchAgents
    LaunchDaemons       - Stored in /Library/LaunchDaemons
    User LaunchAgents   - Stored in ~/Library/LaunchAgents
    These are all background jobs, they are not necessarily bad, but if they are loading old code it could be doing untold damage to the performance & stability of the entire OS. Focus on the System level jobs (the ones inside /Library - the system level) also remove ['failed'] jobs.
    EtreCheck gives a status on launchd jobs…
    [loaded]                  - a running job
    [not loaded]            - jobs that are set not to run, basically harmless, remove them unless you plan to use the associated software (if it is up to date)
    [failed]                    - jobs in a crashed or unknown state, it could be forking processes or using all the system resources, remove these.
    User login items:
    Applications and helpers that are managed inside 'Systems Preferences > Users and groups > Login Items tab'.
    These are loaded at the 'User level', consider removing all of them whilst you troubleshoot.  When you decide to re-add them ensure the software is up to date.
    3rd Party Preference Panes: & Internet Plug-ins:
    /Library/PreferencePanes/ and ~/Library/PreferencePanes/
    /Library/Internet Plug-Ins/ and ~/Library/Internet Plug-Ins/
    Once again these items all must be up to date, or remove them from your system. If the prefpanes manage additional software use the uninstaller or see the developers site for uninstall instructions.
    Read the list of Internet plug-ins carefully, there are often duplicate Flash player versions that won't help stability, it's just wasted space too.
    Don't forget to also update Safari's extensions in it's preferences (if you have any).
    Re-run EtreCheck after cleaning up to see if items have returned (some apps will reload the background jobs when re-opened, so either update or remove the software).
    Hope that isn't too daunting, the OS should be better if there are less old items running at the system level.

  • Intermittent keyboard and trackpad freezes in 10.5.2 (not again!)

    Hi all,
    I'm having a major issue with my MacBook Pro built-in keyboard and trackpad. This issue is incredibly reminiscent of the previous widespread keyboard/trackpad freeze problems, documented in a number of threads, such as here:
    http://discussions.apple.com/thread.jspa?messageID=5860606
    http://discussions.apple.com/thread.jspa?threadID=1196400
    http://discussions.apple.com/message.jspa?messageID=6103438
    http://discussions.apple.com/thread.jspa?threadID=1190210&tstart=0
    What's special about this case is that these issues began very recently, well after I installed Mac OS X 10.5.2, which I recall is supposed to provide a fix for exactly this issue. I've never had a problem with this MacBook Pro notebook before, so this is incredibly unnerving.
    The issue is frustratingly intermittent, but frequent. Sometimes the entire keyboard and trackpad locks up (freezes) and won't acknowledge any input whatsoever. Other times the keyboard and/or trackpad appear to get "choppy", sometimes the keyboard will miss a key causing a typo while typing or the trackpad will suddenly stop moving the cursor. Other times the keyboard will repeat keys by accident, causing maaaaajor typos (kind of like that).
    What's really weird is that I'm seeing the floating "eject" bezel appear (the symbol that you see when you hit the keyboard's eject button) very frequently, when my fingers are nowhere near that key and I'm sure it's not pressed. This even happens sometimes when I'm not using the keyboard at all, just the trackpad (most often while scrolling with the two fingers gesture).
    I've troubleshot this in a number ways. Here is one such troubleshooting session's activity log that I kept while performing the troubleshooting:
    ---- CLIP ----
    MacBook Pro Keyboard Freeze problems troubleshooting log
    * Symptoms are a frozen keyboard and trackpad, that is, no input being recognized by the keyboard or trackpad. Not even the light of the caps lock key lights up when the issue is present.
    * Restarted computer. Issue recurred moments after logging back in and beginning to type.
    * Restarting, zapping PRAM. Issue is gone for a little while but has recurred.
    * Found a single line at the time issue began again in the "All Messages" log shown by Console.app that reads as follows:
    4/24/08 Apr 24, 8:58:15 PM kernel USBF: 551. 7 IOUSBCompositeDriver[0x65b7280](IOUSBDevice) GetFullConfigDescriptor(0) returned NULL
    * Restarting computer again, trying to boot in verbose mode. Can't!! Keyboard wasn't recognized even at this stage! Can't log in either, keyboard unresponsive at login screen.
    * Restarting again (via external USB mouse). Login window comes up and keyboard input is acknowledged. Very strange.
    * Keyboard input lost once again after using the keyboard for a short period of time.
    * Restarting, zapping PRAM again, and Logging in as Leopard's "Guest" user to try and isolate issue...no good, just seconds after logging in, the keyboard and trackpad freeze again.
    * Restarting once again, this time everything works. Noticed that the keyboard backlight is not lighting up in low-light situations. Trying to change the light level with the keyboard keys always results in the keyboard backlight bezel showing up with a prohibitory symbol. This is looking more and more like a keyboard driver issue.
    * Repairing disk permissions, no problems reported. Verifying disk itself, no issues reported. Issue persists.
    Observations and Lessons learned:
    * This issue began slowly, with freezes sometimes happening hours apart from one another, however it accelerated quickly. Now sometimes only mere seconds after logging in, my keyboard is frozen and sometimes the keyboard is even frozen at boot time, so that start up modifiers are not even recognized!
    * Zapping PRAM helps, sometimes, but only for a short period of time.
    * No other traditional Mac fix seems to affect the issue (repair permissions, etc.)
    * The issue occurs regardless of whether or not any peripheral devices are attached to the system.
    Perhaps unrelated, but interesting (and new!) to note:
    * The Bluetooth menu item reports that "Bluetooth: Not available", the Bluetooth System Preference pane is not visible, and System Profiler reports that "No information found" about Bluetooth.
    ---- END CLIP ----
    I've yet to try resetting the SMC, or doing a clean install, but from the copious amounts of users who reported similar errors in the threads I linked at the start of this post, those options only sound marginally hopeful.
    Some of these issues (like the weird eject key suddenly firing on its own) have been present for a little under a week, but the freezing is brand new. The only system-wide change I've made in the last week was installed the MacBook Pro EFI Firmware Update 1.5.1, which was successful (verified in System Profiler; my boot ROM version reads as MBP31.0070.B07).
    So mostly I want to know if anyone else using OS X 10.5.2 is also experiencing this problem. Also, though I'm grateful I could actually use my built-in keyboard to type this message (even with occasional missed keyboard presses, GRRR!!!) my only reliable workaround is an external keyboard. Which is a decidedly annoying thing indeed.
    Help?!?
    Thanks!
    -Meitar Moscovitz
    P.S. AUGH! Just as I was typing that last sentence the keyboard froze again! So I'm actually finishing typing this post via a VNC session. So, so, so so frustrating!

    I wanted to post once again with additional information just in case someone else is also having similar problems. Unfortunately, I'm almost certain that this is probably bad firmware or bad hardware, not a software issue at this stage. Here's why.
    KERNEL PANIC! Take a look at the backtrace and you can clearly see that the Trackpad is to blame. Also, in the system configuration report, not the boot ROM version string, which indicates that I have indeed updated to the latest firmware provided by the recent release of MacBook Pro EFI Firmware Update 1.5.1.
    Here's the Kernel Panic log and system configuration I reported to Apple:

  • My wireless keyboard and trackpad won't connect and i can't sign in

    my wireless keyboard and trackpad won't connect and i can't sign in. yesterday I tested it with my mac air and it worked fine. i deleted the connection from my mac air and tried it again. then it worded. howerver, i shut down my computer correctly and tried it again today. now the same problem again.
    HELP!!

    no, just a usb mouse. but I found an old usb bluetooth hardware. this made it possible for me to make it work. but as soon as I remove the hardware it says "no bluetooth available"! I re-istalled mountain lion but still the same problem.
    additionally I deleted/reset the PRAM. still the same problem.

  • Keyboard and trackpad freeze after being idle for a few minutes

    I have a early 2008 MBP and just today the keyboard and trackpad freeze after not using it for a few minutes.  I was at work when it happened.  I plugged it in and started doing something else and a few minutes later came back and i couldn't move the mouse or do anything with the keyboard, but processes were still running.  For example, I have a fan speed app that sits in the toolbar, and it was still showing current fan speed.  So I restarted it, and it did it again.  So the next time it happened, I closed the lid and opened it up and it fixed it.  It's happened several times now after a few minutes of non use and I just close the lid and it fixes it.  Also, there was a period when I was using my computer for a couple of hours non stop and it didn't have a problem.  Only when I'm not touching the keyboard or trackpad does it do it.  since this keeps happening i have verified the disk in disk utility, done a hardware reset with cmd+opt+p+r, ran through system profiler to see if there were any problems with no results, and it still does it.  Anyone have any ideas?
    It should be noted that not only does the battery not work for more than about 2 minutes, the left I/O board appears to be dying.  The power chord takes a considerable amount of wiggling and adjusting before it finds a place where it will actually charge. The audio out and the USB on that side are the same way. So I am aware of that problem. Also, I have had to take out the right side fan multiple times and disassemble and oil the bearing because it's going bad, which requires taking the top plate off, but I haven't had to do that for over 6 months. In my mind if the problem was caused by taking the top plate off, that would fry the entire top plate, which happened once when a technitian at a local company took the computer apart for a waranty repair.  All of these problems considered, I don't think they would have anything to do with the fact that the mouse and keyboard suddenly won't work after about 5-10 minutes of sitting idle. I have done nothing different since yesterday that would explain why it does this. 
    Also, I can't do anything with the install disk because the CD drive is dead.  But that's mostly because it was a piece of garbage to begin with.
    Any Ideas would be helpful.

    After doing some more digging I was watching processes in Activity Monitor to see if I could see what process is failing.  I think the problem with with Chrome. It only happened when Chrome was open. And since then I reinstalled it and the problem has so far gone away.  So, I think the problems is solved. 

  • Why does my Macbook pro keyboard and trackpad randomly become unresponsive forcing restart in OSX Mavericks?

    Randomly when using OSX Mavericks, since installing yesterday, my mid-2012 Macbook Pro keyboard and trackpad freeze and become unresponsive.
    The computer is still running whatever I was doing, the computer does not crash, i just cannot control it and the only way I have found as a fix is to restart.
    This never happened in Mountain Lion.
    Can anyone help?

    Very similarly.
    Mac Mini late 2012. i7 CPU, 16GB ram. 12GB unused.
    After installing Mavericks, it seems to grind my system to a halt. It is still running (I can move the cursor and activity monitor updates processes) but every application I try to launch results in a colorful waiting sign. It even can take a minute or more before an application shows "any" sign of starting.
    I tried to open a terminal session (so I could manually kill a process) but the terminal session did not even process. It timed out after 5 minutes.
    Acitivity monitor shows 90-95% idle and I have no idea what's causing it.
    I have already rebuild disk and reset permissions (all seemed fine) 3 times.
    I've rebooted over 8 times since last night. I cannot use my Mac anymore reliably.
    Please help.

  • Built-in Keyboard and trackpad become unresponsive randomly

    I've been researching a lot on this but no case seems to apply to mine.
    Out of nowhere, about once a day, the built-in keyboard and trackpad of my 2010 MacBook Air will stop working. The only thing that works is the power button, which brings up the power dialog in which I can't do anything. I can also do a hard shutdown.
    However, if I connect an external mouse and keyboard, they work. With just a restart through them or a hard shutdown, the built-in keyboard and trackpad start working perfectly. This makes me think it's a software issue, and thinking about it, this didn't happen before 10.8.4.
    I ended up resetting the PRAM, the SMC, and finally erasing my disk and reinstalling OSX. After that, I have ONLY installed Google Chrome, nothing else, and it's still happening.
    I don't live in the U.S, so taking it to Apple is impossible plus the issue is not easily reproduced, not to mention the computer is almost 3 years old.
    Any ideas? Thanks!

    The next time you have the problem, note the exact time: hour, minute, second.
    If you have more than one user account, these instructions must be carried out as an administrator.
    Launch the Console application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
    Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
    View ▹ Show Log List
    from the menu bar.
    Scroll back in the log to the time you noted above. Select any messages timestamped from then until the end of the episode, or until they start to repeat. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V).
    When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
    Please do not indiscriminately dump thousands of lines from the log into this discussion.
    Important: Some private information, such as your name, may appear in the log. Anonymize before posting.

  • Keyboard and trackpad unresponsive after sleep

    I've had this problem a few times since I got a refurbished MBA a few weeks ago.
    In preferences, I have it set to require a password when waking up. Most of the time, this goes fine, but sometimes I get the login screen with my username and the cursor blinking in the password field, but there is no response when I touch the keyboard or try to use the trackpad. I try pressing every key and combination I can think of, including the Force Quit combo (cmd-opt-esc). Nothing.
    It also sometimes just has a black screen, and again nothing I do causes any response. In those cases, if I close the lid and then reopen it after a few seconds, I get the login screen, but the keyboard and trackpad don't work.
    The only solution has been to turn it off and on again with the power switch, which is obviously not the most efficient way to wake up a sleeping computer.
    Any suggestions?

    Try resetting your SMC and PRAM.

  • Keyboard and trackpad unresponsive on newest MBP retina (late 2013)

    So I literally ordered the late 2013 model the day it was released (October 23nd) because I had been waiting for it forever.  I got it October 25th.  That SAME DAY I used it, it started having problems.  While I could be scrolling on tumblr or Facebook, the keyboard and trackpad would randomly just stop responding.  It wouldn't move at ALL but the computer still works fine.  One time I was watching Pirates of the Caribbean and the keyboard and trackpad froze just the same without me touching anything.  I had to hold the power button down for 10 secs (the only button that worked) to shut off the computer which also LOST everything I had open.  This has been happening EVERY SINGLE DAY since I used it except one.  I called apple support and they couldn't figure out what's wrong either because it can't be anything I installed since I've only had it for a day when it first happened and all I had was google chrome installed.
    The tech guy from Apple support told me to do the force quit shortcut on the keyboard if it happened again (which it did, as always) and it obviously didn't work because the keyboard was just not responding to begin with.
    This kind of stuff started happening the FIRST day I got my computer four days ago, and it's been happening almost every single day; I don't think the problem is any programs I installed.  I'm thinking I got a faulty computer, which would be very unfortunate because final exams are coming up and it would be very inconvenient for me to send it back and wait for another one.  I also just put decals on it and that would go to waste as well.....
    I waitressed every single night of the week for a month (and counting) in order to buy this for school and I was quite excited to have gotten it...but already problems are coming up with the computer that I spent so much money on.....this is really disappointing.  What should I do? The apple support people aren't fixing the problem and there's no apple store near me and it would suck to have to send it back to wait for another because I have exams right now....and also the money I spent on the decal.

  • My macbook pro keyboard and trackpad lock up randomly

    In the last day or so, my mac has started locking up the keyboard and trackpad randomly.  It happened to me a couple times yesterday completely at random times.  Once when I was playing a game, and another time when I was just browsing the web.  I had Mavericks 10.9.3 at the time of the first lockup, then updated and the second lockup occurred under 10.9.4.  I have a 15" mid-2012 macbook pro. 

    I have to hard restart the computer by holding down the power button.  Closing the lid like in the issue with the retina mackbooks does nothing. 

  • Sometimes the keyboard and trackpad freeze

    I have seen some occurences where the keyboard and trackpad will stop responding on my MacBook Core Duo (1st generation).
    It usually lasts around a second but i had at least 2 occurences where my only option seemed to force a reboot (the Power button does work). I haven't tried closing-reopening the screen to put it to sleep, this just came to me...
    I've searched around for this issue and haven't found a solution to it. Any suggestion? Thanks!
    (The MacBook is 1 year + 10 days old, and yes, i have bought the AppleCare package!

    Hi sholby, welcome to macbook forum,
    Try to reset your PRAM and SMC:
    http://docs.info.apple.com/article.html?artnum=303319
    http://docs.info.apple.com/article.html?artnum=2238
    Also how much ram you have on your macbook, for standard ram of 512 is not good enough and make macbook temporary unresponsive (beach ball) due the lack of memory and become responsive again after they done finish computing.
    But if it was hardware problem and after you reset your macbook the problem still persist, do call apple to check it out.
    Good Luck
