Can't run hardware test to resolve charger light issue.

I've got a macbook pro 17" early 2009 model w 2.93 processor (5,2) with mountain lion (osX 10.8.2) installed on it.
My chargers work but the light cuts in and out, regarless of which charger I use.  I want to run the Apple Hardware Test.
I've tried option-D on start, which I'm told won't work on this model.  I've also tried D on start.  In both cases it just boots to the login screen.
I tried downloading the Apple Hardware Test image for this model from Apple and after converting the image discover it has folders, but there are no files in those folders (yes I turned on hidden file viewing)
How does one run the hardware test on MBP 5,2 once mountain lion is installed.

The original installation DVDs are indispensable for many reasons and can be a challenge to replace. Contact Apple. Explaining to them exactly what you need is the tough part. They will charge a nominal fee for replacement DVDs.
You will need your MBP's serial number - it is printed on the rear case near the display hinge.
In the meantime try an SMC reset. It may fix the problem.
Resetting the SMC on Mac portables with a battery you can remove
Shut down the computer.
Disconnect the MagSafe power adapter from the computer, if it's connected.
Remove the battery (to remove the battery - click here: MacBook or MacBook Pro).
Press and hold the power button for 5 seconds.
Release the power button.
Reconnect the battery and MagSafe power adapter.
Press the power button to turn on the computer.
Still having problems? Replace steps 6 and 7 with the following: 
  6.  Reconnect MagSafe power adapter.
  7.  Press the power button to turn on the computer,
  8.  Then reconnect the battery.

  • Can I run hardware test and repair a disk with Leopard using 10.3 DVD

    Hi,
    I'm trying to decide whether to partition and clone Leopard to my external or partition and install Tiger on the external.
    My iMac came with 10.3.6 install and hardware test DVD's and they (Comp USA) gave me a Tiger drop-in DVD. I upgraded to Leopard through a family pack DVD (when I told my friend I would by one of the install's I thought I would get a DVD, but you only get an install license, oh well). By the way, Leopard runs great in my rev A iMac G5.
    I'm trying to figure out which os to use on the external as a safe-boot incase something happens. If I clone Leopard onto a partition for backup/boot, can I still use the Disc Repair (not permissions) and Hardware Test from the 10.3 or Tiger DVD's to maintain that permission should something bad happen? The way I see it, i'll be able to repair permissions on both the main and external drives using Leopard's disc utility, but I'm not sure if I can repair a Leopard disk or do Hardware Test on that disc using an earlier version of OSX install/Hardware Test DVD's.
    Will earlier versions of OSX repair a Leopard disk and be able run Hardware Test?
    Thanks for the help,
    LowBb

    Yes, that seems to be the case, but I didn't do good enough research when he asked if I wanted a license for Leopard. For some reason, I had it in my mind that a Family pack came with multi DVD's for people. Maybe that's why he sold me a license so cheap. I thought I was getting a bargin, you get what you pay for.
    So, I have the hardware test DVD's that came with the iMac and the Tiger drop-in is just an upgrade with no Hardware Test, you are correct.
    But: (let me make sure I have this right) I should not use the 10.3 DVD's or the Tiger drop-in to repair a disc (not permissions) on a hard drive running Leopard. Is this what you are saying? I kind of thought this would be the case. If it is, I'm going to install MY stuff that I have the DVD's for on the external as an emergency boot disc.

  • Can you run Hardware Test from older DVD?

    Hello,
    My mini2,1 came with OS 10.4. I have the two original system discs. SInce I bought it right before 10.5 was released, Apple sent me a single Leopard Upgrade disc. Does anyone know if the Apple Hardware Test is on the 10.5 upgrade disc? If it isn't, can I run the test from Disc 1 of the original 10.4 DVD's even though the mini is now running 10.5?
    Thanks in advance.

    Excellent. I found the hardware test on the original 10.4 OS X Install Disc 1. Glad to know that the test on the DVD is for my specific computer hardware, and that the current OS on that machine does not matter.This was not clear to me and I could not find an answer on Apple's help pages. And that explains why the hardware test isn't on the 10.5 upgrade DVD.
    Thanks BD and Niel.

  • Can not run hardware test on nMP

    I have Mac Pro late 2013, 6 cores, 16 Gb RAM, Yosemite. I have followed Apple instructions how to run hardware test. Both using D and Alt D at startup. Unplugged devices, plugged devices. The only thing I see is a row of languages and option to shut down or restart with black background I check English and hit return. After that nothing happens. Is there somone who could explain ?

  • Can't run hardware test

    I have a Mac Pro early 2008, os 10.3.3. It is running two monitors, a 30 inch cinema display and a nec multi sync ex231. The video card is nvidia quadro 4000. Recently both monitors are going black after the computer has been on for a short amount of time and I have to manually shut down  and restart. I get a message about no DVI.  This is increasing with more and more frequency.
    I would like to run a Hardware Test. I am shutting down the computer and holding down the D key after the startup chime but before the grey screen appears but hardware test does not appear. It just goes to the screen where I choose a user. Any help please? Thanks.

    AHT is only installed to the Mac when using the original OS installer. I you have migrated via updates it can still be installed, however it is removed when 'clean installing' newer OS's since the disk is erased. The grey OS disks will have instructions printing for starting AHT on the relevant DVD.
    You can find a list of downloads & instructions for finding out your model info (it is easier than searching on Apple.com for them). Only use the ones linked on Apple.com.
    https://github.com/upekkha/AppleHardwareTest
    Try burning it to a CD in Disk Utility - I had limited success with that so I made a script to copy it onto a USB stick…
    https://gist.github.com/drewreece/2e5eed7dbfbd5dd7e929
    It should also be possible to copy the .diagnostics folder back onto the system disk, but that also failed for me too.

  • Can't run hardware test because probing never completes

    I start the hardware test, it tells me probing will take about a minute and I can't do any tests until it completes, the blue bar goes about 95% of the way and stops, I go away and come back half an hour later and nothing has moved. Has anybody seen anything like this?
    Is it because I have an Acer monitor and a no-name three-button optical mouse? Does the Audioworks speaker system plugged into the headphone jack have anything to do with it?
    I wanted to do a hardware test because a particular application gave me kernel panics. Apple support walked me through erasing the disk, reinstalling the OS, and recovering my settings and data from Time Machine. I did not reinstall the offending application and I have not had any more kernel panics. But I still can't run a hardware test.

    I have a workaround, but not a real solution. I unplugged the no-name mouse and then started the hardware test from the applications install DVD. Probing completed, the hardware test completed, and the final report was "no trouble found."
    It's now Apple's problem, because a hardware test should either report trouble or no trouble, but should never hang, no matter what hardware is connected.

  • Can't run Hardware Test at all. PLEASE HELP!

    When hold 'D' during startup, nothing happens.
    When I insert my installation DVD and perform the same task, my MBP ejects the DVD.
    When I try and use the option + D command, and try and connect to my network, the password isn't correct.  This password has worked for everything else I've ever used over said network. 
    I'm officially out of options, can someone please help?

    I'm using a disc that I got from the Apple Strore because I lost my original.
    Retail installation DVD & the System DVD are 2 different types of discs.  The System DVD is machine specific which what you need to run AHT.  Per the KB Article I linked:  "If you updated your Mac to OS X v10.8.4 or later, use the system software disc or USB flash drive that came with your Mac."
    You can get replacement System Install & Restore CD/DVDs from Apple's Customer Support - in the US, (800) 767-2775 - for a nominal S&H fee. You'll need to have the model and/or serial number of your Mac available. 
    If you're not in the US, you may need to go through the regional Apple Store that serves your location to find the contact number. Here's a list of links to all of those - http://store.apple.com/Catalog/US/Images/intlstoreroutingpage.html Another resource:  International Support Phone #s.

  • My 2006 iMac running Snow Leopard won't boot even after erasing and re-installing Snow Leopard (via my MacBookPro), either from the HD or DVD drive.  Can't get it to run Hardware Test.  Disk Utility says disk OK - files are there. What can I do?

    My 2006 iMac running Snow Leopard won't boot even after erasing and re-installing Snow Leopard.   I erased and re-installed by putting the iMac in Target Disk mode and usin my MacBookPro as the host.  But after numerous attempts I still can't get it to boot either from the HD or DVD drive.

  • Running hardware test

    Hi,
    my intel imac has been acting balky lately- running a bit slow at times. It recently started "blacking out"- shutting down somewhat randomly and being slow to restart. I'm trying to run the hardware test from the installation cd's that came with my machine, but I'm unable to get it to run.
    I've tried using installation disc 1 (my machine came w/ version 10.4.4 of the OS), installation disc 2, holding down "c", holding down "d", holding down "apple-d" etc to no avail. Any ideas how I can get the hardware test to actually run?
    I just want to try to diagnose the random shut downs.
    Thanks!
    Jason

    have your tried starting up in safe mode ?

    I suspect you have hardware problem with a fan sensor. Doing a software install will not help the machine needs to be taken in for service. If you run Apple Hardware Test in Extended Mode it should reveal the error code. If it does not then run AHT an additional 2-3 times to be sure in Extended Mode. Each pass will take about 30-60 minutes.

  • Why can't I run Hardware Test?

    I am trying to figure out if I have a hardware issue and was told to run the Hardware test.  my iMac is the late 2010 model and shipped with Mac OS X (10.6.4) and currently upgraded to Mountain Lion 10.8.3.
    I have tried running test by restarting and pressing "D", option "D", and both ways with and without the original applications install DVD in.  But every time I just get the login screen that I normally get.  Am I doing something wrong? 
    This is above my pay grade, but I am having trouble running Adobe's Illustrator and a colleague using the same set up said they had the exact same issue and it turned out to be bad RAM.  So, I am trying to run the hardware test to determine if I have a hardware or software issue.
    Thanks in Advance,
    Rob

    See this thread and baltwo's directions, which will enable you to start the AHT directly from the boot volume, that is if the AHT (.diagnostics) isn't already present.
    https://discussions.apple.com/thread/4427984?start=0&tstart=0
    But first, using the starting suggestion there, unhide hidden folders and see if you have .diagnostics in the given location. If you don't, then proceed with the rest of the suggestions, but be sure to use the corrected Terminal command later in the thread.
    Still, disc 2 and the D key should work. Don't know why it isn't.
    Also, if you just want to test the RAM, get Rember. But close all applications first. It may be necessary to run several loops before it finds anything.

  • Running Hardware Test from second Mac?

    My wife has a 2.4 GHz Intel Core 2 Duo iMac. It has a faulty DVD drive - actually a disc has been stuck in there for some time and we haven't been able to get it out. That is not our current issue, although it makes troubleshooting much harder.
    Her iMac is getting slower and slower and I promised I'd run some tests. I can't run the Hardware Test on that machine from the original install disc because of the faulty DVD drive. I'd like to run the test remotely from my MacBook Pro but can't work out how to do that. I have tried booting her Mac in Target mode where I can run Disk Utility on my machine and repair her hard drive but when I insert her original Install Disc in my laptop there is no Hardware Test visible on it. I have tried to get access to my DVD drive from her iMac but 'DVD or CD Sharing' being turned on in 'Sharing Prefs' on my machine doesn't seem to bring up any shared discs on her computer. Maybe it's still trying to access her faulty DVD drive?
    Is there anything I can do here to run some hardware tests on her machine? I'd like to do that before I start doing clean installs of the Mac OS on hard drives etc. I'm a bit stuck.
    Thank you

    Five ways to eject a stuck CD or DVD from the optical drive
    Ejecting the stuck disc can usually be done in one of the following ways:
      1. Restart the computer and after the chime press and hold down the
          left mouse button until the disc ejects.
      2. Press the Eject button on your keyboard.
      3. Click on the Eject button in the menubar.
      4. Press COMMAND-E.
      5. If none of the above work try this: Open the Terminal application in
          your Utilities folder. At the prompt enter or paste the following:
            /usr/bin/drutil eject
    If this fails then try this:
    Boot the computer into Single-user Mode. At the prompt enter the same command as used above. To restart the computer enter "reboot" at the prompt without quotes.
    Running the AHT doesn't make much sense for fixing slowness. If the computer is working, then there is no hardware failure. See the following:
    Things You Can Do To Resolve Slow Downs
    If your computer seems to be running slower here are some things you can do:
    Start with visits to:     OS X Maintenance - MacAttorney;
                                      The X Lab: The X-FAQs;
                                      The Safe Mac » Mac Performance Guide;
                                      The Safe Mac » The myth of the dirty Mac;
                                      Mac maintenance Quick Assist.
    Boot into Safe Mode then repair your hard drive and permissions:
    Repair the Hard Drive and Permissions Pre-Lion
    Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    Repair the Hard Drive - Lion/Mountain Lion/Mavericks
    Boot to the Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND and R keys until the Utilites Menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD disk icon and click on the arrow button below.
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
    Restart your computer normally and see if this has helped any. Next do some maintenance:
    For situations Disk Utility cannot handle the best third-party utility is Disk Warrior;  DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.
    Note: Alsoft ships DW on a bootable DVD that will startup Macs running Snow Leopard or earlier. It cannot start Macs that came with Lion or later pre-installed, however, DW will work on those models.
    Suggestions for OS X Maintenance
    OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep.  Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger.  These utilities have limited or no functionality with Snow Leopard or later and should not be installed.
    OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive.
    Helpful Links Regarding Malware Protection
    An excellent link to read is Tom Reed's Mac Malware Guide.
    Also, visit The XLab FAQs and read Detecting and avoiding malware and spyware.
    See these Apple articles:
      Mac OS X Snow Leopard and malware detection
      OS X Lion- Protect your Mac from malware
      OS X Mountain Lion- Protect your Mac from malware
      About file quarantine in OS X
    If you require anti-virus protection I recommend using VirusBarrier Express 1.1.6 or Dr.Web Light both from the App Store. They're both free, and since they're from the App Store, they won't destabilize the system. (Thank you to Thomas Reed for these recommendations.)
    Troubleshooting Applications
    I recommend downloading a utility such as TinkerTool System, OnyX, Mavericks Cache Cleaner, or Cocktail that you can use for removing old log files and archives, clearing caches, etc. Corrupted cache, log, or temporary files can cause application or OS X crashes as well as kernel panics.
    If you have Snow Leopard or Leopard, then for similar repairs install the freeware utility Applejack.  If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line.  Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. Applejack does not work with Lion and later.
    Basic Backup
    For some people Time Machine will be more than adequate. Time Machine is part of OS X. There are two components:
    1. A Time Machine preferences panel as part of System Preferences;
    2. A Time Machine application located in the Applications folder. It is
        used to manage backups and to restore backups. Time Machine
        requires a backup drive that is at least twice the capacity of the
        drive being backed up.
    Alternatively, get an external drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
      1. Carbon Copy Cloner
      2. Get Backup
      3. Deja Vu
      4. SuperDuper!
      5. Synk Pro
      6. Tri-Backup
    Visit The XLab FAQs and read the FAQ on backup and restore.  Also read How to Back Up and Restore Your Files. For help with using Time Machine visit Pondini's Time Machine FAQ for help with all things Time Machine.
    Referenced software can be found at MacUpdate.
    Additional Hints
    Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
    Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
    Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
    Check for applications that may be hogging the CPU:
    Pre-Mavericks
    Open Activity Monitor in the Utilities folder.  Select All Processes from the Processes dropdown menu.  Click twice on the CPU% column header to display in descending order.  If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar.  Click on the Force Quit button to kill the process.  See if that helps.  Be sure to note the name of the runaway process so you can track down the cause of the problem.
    Mavericks and later
    Open Activity Monitor in the Utilities folder.  Select All Processes from the View menu.  Click on the CPU tab in the toolbar. Click twice on the CPU% column header to display in descending order.  If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar.  Click on the Force Quit button to kill the process.  See if that helps.  Be sure to note the name of the runaway process so you can track down the cause of the problem.
    Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file.

  • I want to run hardware test on my Power Mac G5 but it isn't working.

    What I tried:
    I have the original install disc 1 which came with the machine in the optical drive (which is the usual one). I printed the hardware test guide which is on the disc, disconnected everything but mouse, keyboard and monitor. I tried to boot, pressing the Alt/Option key, but the "system picker" or boot menu won't show up. What happens is what somebody described as for "old world" macs: my system boots with no finder window open and without the white screen and apple logo (which usually shows up during startup).
    I also tried something I found in a user manual pdf for Power Mac G5 on the apple archives: Booting and press-holding C (btw it's strange that this manual says something different than the manual on the original disc). What happens here is that my machine is booting from the original disc but it boots in Installation mode. I looked at every drop-down-menu I could find there for several times but there is definitely no hardware test, since this is thought to install Mac OS 10.4.
    I also tried the Intel-way and holding D during boot, but no surprise, it only booted the first drive (like it should on a pre-Intel).
    But something about this all is very strange. Yesterday night I tried all these steps above and when I was close to fall asleep in front of my monitor it suddenly worked and I made it finally into the hardware test. If I remember correctly, I was holding down the C key, but as I said a was pretty dizzy and can be mistaken. I ran hardware test once enhanced and it stopped during ram, giving me an error code I wrote down. But since I made it into the test and was so tired, I thought "lets continue tomorrow" which was my epic fail for this year, I guess. Today I repeated every step, every way I tried but it just doesn't work; and I read sooo many forums and Q&A's.
    By the way here is my error code which appeared after 49 minutes (to proof I didn't dream this):
    "2MEM/1/4: DIMM3/J14"
    Why do I want to do this?
    Around the 1st of September this year my Power Mac G5 didn't boot anymore (the fan speeding issue). After reading a little online I came to the point that its either my Ram memory or its my graphics card or its Pram or NVram. I resetted Pram and NVram, I also replaced battery and then it booted again for one day but on the following day it didn't. I repeated every step but the battery replacement since it was a brand new one. It can only be Ram memory or my Graphics card (which is the standard one for this machine).
    Since then my Power Mac was rarely in use, only two or three times in Firewire Target Mode to access some of the data. Yesterday I wanted to do this again; booting it in FT mode but I must have connected my keyboard too late during booting and my machine surprisingly booted just fine! I was so stoked about this! Then I wanted to find out why it didn't work for a while and started several steps. Ran maintanance scripts, repaired the system volume, checked for enough free space, checked my Ram and then I stumbled on the interwebs over the hardware test which is delivered on the original install disc 1 and I never heard about this before (strange enough). What followed is written above.

    Sorry for the German but I think you still get it. The PPC was delivered with 10.4 and I bought it used from a friend with his original Update disc to 10.5 and I updated to the max, 10.5.8. I have 2x 1TB drive (similar ones) together as a Raid0 and three partitions on it. (I know now that it doesnt make that much of a sense).
    Yeah so I really want to find out why my machine didn't work for three months but since it is so old and I'm a student, it doesn't make any sense to me to go to an Apple store or similar to have it expensively serviced since there is no guarantee that these guys really help you (heard some stories about the local stores here).
    Is there a way to re-access the hardware test and run it to the end?
    As you might have noticed, I'm pretty desperate. I would soooooooo appreciate it!!
    Best,
    Erik

    "2MEM/1/4: DIMM3/J14"
    Replace the memory in the DIMM 3 slot.
    If you are running Mac OS X 10.5 you can use this program to test your G5's memory:

    It will subject your RAM to a more thorough test than Apple Hardware Test.

  • Hard drive issues; how to run hardware test

    A couple of weeks ago my hard drive experienced what I would call "minor crashes". The computer booted up to the grey box with the question mark, and would do nothing more. The hard drive also made unpleasant noises. I think I got it back by resetting PRAM, but it happened a second time, and then a PRAM reset again got it back. Needless to say, I'm nervous about this drive.
    I have Apple Care until January '09 (this is an '06 Intel machine) and figure I should try to move on figuring out what's up ASAP (both because I don't want a drive failure, and because I only have a few more months of Care).
    I'm guessing that I should run the extended hardware test, but I can't seem to get it going using the Leopard disk I used to upgrade the OS. Do I need the original install disks (which I can't find, of course!)? What else can I do to determine if I have an issue that calls for hard drive replacement? If I need a new hard drive (it now seems small at 250gb anyhow), will I be able to do it myself (assuming Apple Care won't take care of it)?
    Any insights welcome. Thanks!

    Give it a try, if not you'll need to dig up your Disk 1!
    +Some Intel-based Macs ship with Apple Hardware Test and Mac OS X 10.4.x preinstalled on the hard drive. If an Erase and Install installation of Mac OS X 10.5 Leopard is performed using a retail Leopard installation disc, Apple Hardware Test will be erased and not reinstalled on these Macs.+
    +If you're in this situation and need to use Apple Hardware Test, simply start from the DVD that came with your computer (not the Leopard installation disc) while holding the "D" key. Apple Hardware Test will run from the DVD.+
