Hardware Test on MacBook pro shows Error

After my MaBook Pro2,1 - Intel Core 2 Duo - 2,33 GHz & 2 GB Memory - with 10.6.8
freeze on startup every time, only running in "Save Boot" mode
i choose do perform a hardware test with the version 3A116 on a earlier Mac OS Install Disk.
The test (3 times) shows an error code (after 1. test i switched memory cards), i am not able to interprete this:
4SNS / 1 / 400 000 00 : TBOT
Does someone know the code?

Forget the code yoyu have a hardware problem. Only Apple, or a AASP, knows the codes and what they mean. Take it to a genius bar.

Apple Hardware Test on Macbook Pro Core 2 Duo (early 2007) with no DVD?

Hi,
My Mac is keep on freezing and I would really like to know what is wrong with it. (I did PRAM NVRAM reset 100 times... didnt help.)
I can't find my OSX Tiger DVD which was included when i bought my Macbook Pro in January 2007. So I've been reading through forums like crazy trying to find another way to run AHT (apple hardware test). So far I came up empty.
So my question is: If I upgrade from Lion (which is my current osx on this machine) to Mountain Lion, will I be able to use online AHT (option + d)? Or more general: is there any way to run AHT on my machine or any other way to find the broken component. or should i just throw it away?
Thank you.

Take your machine into your local Apple Store or an AASP and they will run free diagnostics. If there's a lot that needs to be done on your machine to get it back up and running, ask about Apple's flat-rate repair pricing. For less than $350, you could have a machine that is almost like new.

Hardware Test on MacBook Pro running Mavericks not working, Help!

Hi Folks,
I am hoping someone can help me get the Apple Hardware Test working on my Mid-2012 MacBook Pro (model 9,1) running OS X Mavericks v10.9.5.
It came with Mountain Lion pre-installed. I successfully ran Apple Hardware Test when I received it by holding D while powering up. No problem. Since then I have done nothing involving OS X other than installing Mavericks.
Recently I have installed some RAM and wanted to test it. I find the Apple Hardware Test no longer works. The mac simply boots into the username screen as usual.
Here's what I've tried:
0. Reading instructions on Using Apple Hardware Test - Apple Support. Ensured Mac was plugged in, and confirmed I pressed D prior to grey screen, and confirmed I held it down. No effect.
1. Pressed Option-D while powering up. No effect.
2. Searched for .diagnostics directory in /System/Library/Core Services/.diagnostics
It didn't appear to be there. (I don't know why, I can only guess that the upgrade from Mountain Lion to Mavericks must have hosed it)
So, I found instructions on how to obtain the AHT .dmg file for my version of MacBook Pro and downloaded it.
It's at this link by the way:
http://download.info.apple.com/Apple_Hardware_Test/022-5879-A.dmg
Then copied the .diagnostics directory from the .dmg into the /System/Library/Core Services/ directory on my HDD.
Tried again, pressing D after powering up. No success. Option-D, same thing.
So, I don't know what else to do. IEverything I have read indicates the test should run. It doesn't.
Can anyone help?
BTW: I don't have an install disk. System came with Mountain Lion pre-installed and I subsequently upgraded to Mavericks a while later.
Thanks in advance,
- BS

How to obtain apple hardware test for MacBook Pro (15-inch, Mid 2009), how to obtain apple hardware test for MacBook Pro (15-inch, Mid 2009)

I no longer have the software disk (OS10.5) that came with my MBP in July 2009. I only have the $10 Snow Leopard disk from Apple, which does NOT seem to contain any Apple Hardware Test (AHT). I have tried starting while holding d or option keys to no avail. Does neither my laptop nor OS 10.6 install disk have AHT? If not, can the appropriate AHT be obtained? My wife has an older MacBook & her original 10.5 install disk, but it will not launch AHT in my MBP. Any suggestions?
Thanx

I like the advice to contact Apple and simplky pay for a new AHT. I did that, giving them the serial number of my MBP and indicating it was a June 2009 model, 2.66 gHz Core 2. However .....
I received yet another Apple FedEx shipmet with yet another different Mac OS X Leopard install DVD; this makes three in all!! Just as with the 1st DVD, these two will NOT mount on my desktop, are NOT seen by Disk Utility (or by Drive Genius) and cannot boot my MBP laptop in either of 4 different modes: (1) start-up with "d" (2) start-up with "option d" (3) start-up with "option" (4) start-up with "c". Apparently none of the disks I received have Apple Hardware Test on them, although that is what I paid for in early December. It may be that the last two disks really do have Mac OS X Leopard on them, but because I am now running OS 10.7.5 (purchased from App store with no AHT), the disks cannot be seen by my laptop.
          The two most recent incorrect DVDs I received have the following part numbers:
                    SRF2Z691-6037-A [indicated on packing slip 10.5 Retail-International]
                    SRF2Z679-6341-A (indicated on packing slip 10.5.6 Retail (PCrly 09) In]
          I happen to have MacTracker app 7.2.1. It indicates that my laptop is a MacBookPro 5,3 model A1286 EMC2325 and requires Apple Hardware Test 3A171. Apple never sent me the correct AHT.
          I suspect that Apple's cost to ship 3 incorrect DVDs by 1- or 2-day FedEx vastly exceeds the $17.44 price I paid for a working version of AHT for my computer, but have yet to receive.

I have Mac Pro 2010 model and it's giving heavy fan noise,so run the Apple hardware test but it's showing the Error: 4SMC 1 40000000 please help me in this issue.

My MacBook Pro shows a grey screen at start-up how do I fix this problem?

My MacBook Pro shows a grey screen when I try to login and won't go onto my homepage. Why has this happened and how do I fix it?

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. 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. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

Wi-Fi: No Hardware Installed Problem - Macbook Pro

After connecting Wi-Fi and surf online about 20 minutes, Wi-Fi is stop. Can not turn on and turn off. It shows "Wi-Fi: No Hardware Installed". I shut down the computer. Leave about 20 minutes. Then power on the computer. Wi-Fi is working well again. But after surfing online about 20 minutes (Especially when watching streaming movie), Wi-fi is stop again. Problem is repeating. I have tried several way to solve by reading post. No way work to solve this problem. I have faced this problem since Snow Leopard, now on Lion. Still facing problem. If somebody know how to solve, Please..

Dear,
Had the same issue with my MBP (mid 2010) and tried everything.
The hardware test did not give any error and all kind of resets did not solved anything.
Finally, I just returned my Mac to the Apple store and got it back after 3 days and with a new WIFI card in it (and a bill of 250 €).
I'm absolutely convinced that there is a link between the upgrade to Lion and the 'broken' WIFI card but Apple keeps denying it.
So, Mr. Tint, no choice: bring your Mac to the repair shop and pay.

My macbook pro shows blank screen when I started..help me..

My macbook pro shows blank screen when I started . (It's like in same state when power off. ) fan sound and hard disk is running. So i connected it Through external monitor via mini display to VGA cable. I can see everything on external monitor. My display of Mac needs to change? How much it cost ?? I found so many forum discussion said that if nvedia card is faulty then its happen...let me know suggestions...I given it to apple care service station n they r telling yr display needs to change its cost me a lot.. I can't afford. And can't spend that much for 3 yr old version as new versions of macbook pro is cost vice reasonable.. can I have any suggestion?

If running 10.7 or later hold down Command-R at Startup.
This should invoke recovery Mode.
Choose Disk Utility.
Select your Hard drive. Inspect the SMART Status in the lower right of the window for "Verified".
Select the Mac OS X Volume (originally Macintosh HD) click (Repair Disk)
If errors, run again until it comes clean or gets stuck.
Report any error messages.

I ran a hardware test and this was my error

I ran a hardware test and this was my error#4MEM/40/40000006:B:1 C:0 R:1 - what does it mean?

Sure, your Mac Pro's memory is installed on two cards that you can remove, and subsequently inspect or remove the RAM. Read here to determine where it is and what to do:
http://support.apple.com/kb/HT4433
If you're lucky, merely removing and reinstalling the memory modules may clear the fault. If not, it is possible one or more of the DIMMs (Dual In-line Memory Modules) has failed or is no longer meeting the Mac Pro's requirements.
Memory is not difficult to install and is not terribly expensive. Most vendors have a lifetime guarantee.

My Powerbook boots up every few times and the hardware test still gives me -9972 error

My Powerbook G4 15" aluminum 1.67Ghz 10.3.9 Panther won't start up.
(I did a backup on an external drive not long before it failed)
have gotten lost in my research on apple forums and knowledge base.
From the original install discs:
The Hardware test gives the error.
"2STF/8/3 ATA-100 ata-6-Master (-9972)"
The Disc utility does see my harddrive but fails to repair with the messge:
1 volume cannot be repaired,
'Invalid node Structure'
Disk 'no valid packets (-9997)'
I do have a useless partition from TechTool 4 and had successfully run the programs just before Powerbook failed.
aid everything was ok, with no warnings.
found somewhere a link to a hardware test code list, that said 9972 could be the cable (ribbon?) to the drive needed to be reset, replaced, or the harddrive replaced.
our local New Orleans 'official' Apple Tech guy calimed it was the harddrive and not worth replacing. he whined that it would take hours, tho the guys on ifixit claimed only half an hour.
i have since got a refurb MacBook (even older it turns out) with Tiger, but I miss my 15 incher Powerbook. (on very tight budget)
the battery got zapped by lightning last year and have struggled with it ever since. it won't fully recharge.
Right now have got it on the AC without the battery to try to charge the backup battery.
I have managed to restore it several times after crashing, inspite of my tech guy claiming otherwise. but have never really opened it up besides just looking at the memory slots. just one filled with 512 card.
so any advice, or suggestions.
I've been messing with my Power book for like 10 hours and finally finished replacing the hard drive. (just installing the software and all the updates took almost 2 hours by itself) Now it boots up every few times and the hardware test still gives me -9972 error.
<Re-Titled By Host>

My friend. Do not despair.
Firstly, you have a backup. Kudos.
Secondly, i suspect the hard drive in the machine is more than just a few years old. Hard drives die. I suspect the hard drive is the issue, not the cable.
Thirdly, it is worth changing the hard drive and take the ifixit advice. Simple to change. If it will be your first time changing the hard drive, just be organized and follow the steps carefully.
Now, before we decided it is the hard drive we need to confirm this.
I would check if SMART reports favorable conditions for the drive. Disk utility can tell you.
If good then I would zero out the drive. This allows the drive to excercise every sector and will build confidence of a well prepared drive going forward.
You can then restore from backup.
The other option is to replace the internal HD with a new one, perhaps with more storage.
As an FYI, I replaced the drive on my powerbook G3 and it's faster, quite , has more storage and gives me some peace of mind. Worth the money. The little guy runs beautifully.

Krishnaraj7777,
you can try this: boot your MacBook Pro into Recovery mode by holding down a Command key and the R key as it starts up. Once the OS X Utilities menu appears, select Disk Utility. On the left-hand side of the Disk Utility window, select your internal disk’s boot partition (typically called “Macintosh HD”). On the right-hand side, press the Verify Disk button if it’s not greyed out; if it is greyed out, or if it reports that errors were found, press the Repair Disk button. Once the verification/repair is completed, exit Disk Utility and select Restart from the Apple menu to restart in normal mode. Do you get past the white screen now?

MacBook Pro shows up twice under Shared in finder sidebar once as PC

This just started today. I have my iMac and MacBook Pro networked through Airport Extreme. Today my MacBook Pro shows up twice under my iMac finder sidebar. First icon is itself (MacBook), second icon is PC. Both with the same name. Get info shows the second icon as PC Server. I cannot connect to the PC icon, which I'm assuming is a good thing.
Why would this suddenly happen, and how do I get rid of it? I've restarted airport, repaired permissions on both machines. Checked to be sure that only AFP is check under File Sharing on both. Network preference pane WINS shows no servers connected on Airport or Ethernet, etc.
Anyone?
Appreciate any help with this. I'm definitely not a networking expert

Ok, ive had this problem for ages and i think ive pretty much figured it out, your computer is showing your macbook over your network and through Bonjour (apples own wireless connection) Still not sure why it always shows it as a PC though, or as a server...
Anyway, I ive found where it originated from, if you go to System Preferences>Sharing, at the top you will see your computers name and underneath it will say "Computers on your local network can access your computer at:" and its name will be whatever the 'PC server' is called on your finder sidebar, in your case "tosha". You can test it by changing the name to something like "tosha1" by clicking the edit button, in may cases the extra shared computer will disappear, but, after a while it will reappear and will now have the new name. =[
Sadly I dont know how to stop this but I suggest you take screenshots and go to an apple store, tell them about the problem and hopefully they will have an answer for you, they know everything! And even if they dont, check their machines to see if they have the problem, and if they dont, look at the settings and try and find why.
Im sorry I cant be of much help but im getting closer to the bottom of this and im sure its linked to bonjour! Ill keep you posted if anything else happens!
p.s. Im not a networking expert either! Im just as stumped as everyone else!

My imac is doing strange things:
-delaying between users: when closing session it goes to blue, then takes a while to appear users signin box, and then wont recognize mouse command to enter until a couple of minutes later... then everything seems alright until....
-it gets stuck between things, the rainbow wheel appears and its just delays there forever....
-and every now and then the mouse starts flickering and bouncing wildly onscreen.
I ran the appel hardware test and it detected an error:
4MOT/4/40000003:HDD-1233
Does anybody know what that means? HELP!

WZZZ answered about where to get iStat. And do check the SMART status. If it is an overheating problem due to a fan or logic board problem, your hard drive is possibly cooking itself to death. If so it isn't a faulty hard drive even though the hard drive might fail. So assuming it's a temperature problem, even if you are able to repair things on the disk with software, that is working on symptoms, not causes. I could be wrong however.
RE: AppleCare: Your iMac came with one year of AppleCare (Apple's warranty program), but within the first year you can buy 2 more years. You have to extend by the one year anniversary of purchase of the computer. Your 10,1 is too old to still be in the first year, and since you asked what it was, I'm sure you don't have it. Bottom line meaning is that whatever this problem turns out to be, you'll have to pay for it. Unless there is something like this. It is for 2011 iMacs with certain Seagate drives. You can put in your serial number for fun, but it looks like yours is too old. Lastly, some people have had Apple help them anyway if it is just out of warranty, but many have not. Your machine is one of these. Type in 10,1 in the search box. Is there an Apple Store near you? Just b/c it's out of warranty doesn't mean you shouldn't have it looked at by Apple. But no one here can say at all what Apple will or will not do.
Hope you get it taken care of!
