MacBook Pro :: Crashed And Stopped Working - Internal Hardware Not Detected?
Aug 27, 2014
So recently my Mac crashed and stopped working as explained there: Major crash?
I was thinking, as everyone, that this problem was coming from the hardware. So I got a new one, and tried to install it. BUT the problem is still here! It just doesn't detect my internal hard drives anymore!! (For the ones who didn't read the original thread, the flashing folder with a question mark on it was appearing each time I was starting my mac, and I couldn't repair the disk since it wasn't detected.)
What could prevent my hard drives from being detected??
Info:
MacBook Pro (13-inch Mid 2012), OS X Mavericks (10.9)
I had my computer plugged into some external computer speakers (nothing where I had to downlaod any software, I have used these speakers before), and when I removed them, all of a sudden the built in speakers weren't working. I tried to adjust the vollume, but I get the volume image with a little "forbidden" circle and cross underneath. I tried adjusting the settings in System Preferences, but when I got to the audio settings there was only the one "Optical digital-out port". I then updated my computer, but still no luck. Lastly I went to Utilities and to Audio Midi Setup to reset everything to the default settings, but I am unable to adjust everything. It's all that lighter shade of grey that tells me I can't select it.
My internal speakers in my PowerPC G4 just magically stopped working! It recognizes them in system preferences. And yes, the volume is up. I dont know what happened. The headphones do work. I havent tested external speakers yet, but that's next on the list.
This may appear to be a hardware issue, but I'm of the opinion that it will prove to be a software problem, so I'd appreciate it if the topic was left here. Over the past couple of days I've had problems with getting the internal speakers on my 1.33ghz PB to work while I've been logged into my user area (the only user area on the computer). When the computer is initially booted up I hear the usual boing! but once I'm signed in I can't get any sound out of the speakers. I've been to 'Sound' in System Preferences and checked that all of the settings are correct and that Mute isn't selected, and everything appears to be ok. I've also tried inserting a movie DVD to see if this changes anything, but the DVD starts a plays the video, but still no sound.
I haven't dropped the computer, or spilt water on it, so I would think it is almost definitely a software issue (backed up by the fact that I get the initial BOING!! sound). I never play the speakers at full volume so I would very much doubt that they'd be shot either. I've tried shutting down and restarting the computer, but this does not always fix the problem. A perfect example of how erratic the problem is that when I booted the computer around 10 minutes ago there was no sound - tried playing music in iTunes and nothing... I've just started iTunes and wahey - music playing through the speakers! Also, last night while playing a DVD, the sound was perfect for a good 20 minutes or so, but then all sound from the speakers was lost and only the video was running.
My internal hdd isn't detected anymore while booting. What happened: after plugging in an USB-printer my macbook freezed immediately and I had to shut down by pressing 5 seconds on power button. I pressed power on button and my internal hdd isn't detected anymore while booting (question mark is blinking).
After replacement by a new ssd and booting via USB the new ssd isn't detected, too.Is the internal SATA3 cable broken or is it a defect of some kind of SATA3 controller assemled on mainboard?

When accessing the website; 'WhatUsersDo', which is used for testing websites, you are required to provide an audio recording of your thoughts about the website which you are testing, However, I am unable to submit an application to become one of the testers, as it is saying that I need to enable a microphone before I can continue with my application (as you are required to take a practice test during the application).
I have looked through other forums, and my microphone is working fine.

My Mac Pro, used very little as yet in this life following a fortuitous acquisition from my former company, is failing to recognize one of the three hard disks. I have a 320 gb system disk running Snow L, and two 500 gb disks which are currently empty of data. Following boot, the second of the 500 gb drives isn't available - it doesn't appear on my desktop, or in Finder, or in the side bar when I launch Disk Utility.
The system profile information returns a single line saying there was an error when trying to detect information about my disks - it doesn't give me information on any of them. In its previous life this disk was a mirrored RAID array (with the other 500 gb drive) used a shared file server for standard office documents etc in what I would call a modest load environment - it was no media studio!
I installed 10.5.7 yesterday. Immediately after the installation was complete, my Apple bluetooth keyboard stopped working. Went into Bluetooth system settings, and it said that there was no bluetooth hardware found... (it's built into the machine!!)...
Also, every time I start iTunes, it gives some weird error about Adobe Flash player. I'm not at home now so I don't have the exact wording of the error with me, sorry...
My headphone jack was working just fine until this morning when I opened my computer. It's plugged in, but the sound keeps going through the head speakers. I have done the system preference check to make sure it is not muted.
Disk Utility Disk Warrior Drive Genius 2 TechTool Pro 5
When I tried to rebuild the hard drive on each one, they all gave me the result, "failed," basically, except TechTool Pro 5, which said it completed it with no problems, but obviously it had no idea what it was speaking of because the external hard drive still did not mount on the desktop. I chose basically every thing that each program offered me that might help the disk, but I think it's finally dead. I've had to rebuild it about 3 or 4 times now and it's only been a year or so...
Quicklook has stopped workingon my MacBook Pro OS 10.6.8. Pressing the space bar on a file yields nothing. Is there a way to update or reset it so it starts working again?

My Macbook has suddenly stopped having internal speakers in the sound preferences.When I turn it on, it plays that familiar synth chord sound to say all is ok, but it wont play any audio. So videos and itunes etc play but the sound isn't produced.When I try to turn the volume up or down, the indicator says the volume is up full, but I cannot adjust it. Underneath the volume measurement there is a little sign in white like a no entry sign, meaning that adjustment of volume is not available.I gues this must mean that the speakers have been disabled, but can't figure out how to enable them.
during SW to my mini-mac wireless key board the keyboard stop responding. now i have left without an ability to work with my wireless keyboard. is there any why to reset the keyboard to default setting so it will come to live again..
Recently my 2 month old (+/-) rev B MBA USB stopped working. When I plug in a thumb drive, DVD drive or anything, the power light on the usb peripheral comes on, but the drive does not mount. I am running SL, and until last week I had no issue.
The i key has stopped working on my 2011 Macbook Pro. i've tried taking the key off and cleaning underneath, pressing it hard, pressing on the side, tried turning off text to speech...
All the other keys are working fine. Tried to book a genius bar appt but there are none available and i can't afford to pay for tech support!
Not sure why, but all of a sudden have no sound effects. When I go to System Preferences all the alert sound effect choices are grayed out. When press the volume buttons, can't adjust settings and there's a strike-out symbol underneath the bars.
My USB Drive on my Macbook Pro stopped working. I have done power downs, resets, and still not working. thinking a driver is not there. Running OS X 10.7.3 . Looking for some options before taking it to hardware repair for service.

I plugged in the charger after not having my computer charging since the morning. My charger did not work and pluged it in to other sockets around the house. I then tried my sisters charger, which was working for her computer. The odd thing is that after I tested it on my computer it no longer worked for my sisters computer. This is so confusing and I don't want to pay $160 on two chargers.It is the L style charger and we have had both for about less than 6 months.
i bought a macbook pro, OS X lion, version 10.7.4 a month ago. one of my USB port suddenly stopped working. i am a new mac user, so i have very less idea about mac.
MacBook Pro stopped working all of a sudden. There was battery left, but it shut down completely and won't even charge..out of nothing. MBP is just a few years old.
I'm trying to do a video chat through ichat and the other person can't hear me though she can see me just fine. I'm doing this through OS 10.4.9, not XP.
It's not a bandwidth issue because I switched from wifi to a direct connection with my cable modem and the stats say I'm running around 100% on audio.
I tried recording sound on garage band, but it picks up no sound.
In system preferences the sound input is set on "internal microphone/built-in," the Input volume is on max, but the Input level meter does not move at all.
Installed MSOffice on my MBP with SL already installed. Office immediately wants to be updated with a "critical update" which is 200+ MB. Nearing the end of the update I get a message that says the update had a technical error, and it then shuts down. After this nothing in Office works.
Then I tried to post a message on MS's Mactopia forum and it won't let me log in. So I can't post, and I can't create a new account.I dragged the corrupted Office to the trash (their uninstall program wouldn't work either). Reinstalled Office and everything works. But it's not updated.
I have been using the line-in on my MBP to record with my guitar/bass for about 3 years. I use Logic Express 9 to record. All of a sudden, the line-in no longer works and I get this awful clicking sound the entire time.
I noticed a couple of days ago that my sleep indicator has stopped working. When I shut the lid the computer goes to sleep.... when i open it back up after 30 seconds or a minute msn tries to reconnect and i heard the cd make that little noise that it does... anyone know of anything i could try to make it work again?
This is my first mac, it's a Macbook Aluminum Unibody 13" 2.0GHz... this is the only problem I've encountered.... I know it's pretty minor, but I like things to work as they're supposed to, especially when they're this new.
I went on vacation for 1 month and when I came back my mac wouldn't charge! In the corner it would say "Not Charging" and and the battery lights do not turn on when I press the button on the battery itself. The mac only works when I have it plugged in. Do I need a new battery? It's a 13" white macbook, about 2.5 years old. It has the Intel processor but not the Core2Duo.
I'm sitting here typing a paper and my illuminated keyboard goes out when its set to be on all the time. I try adjusting it manually and it won't let me. My controls also stopped working on adjusting brightness. When I click increase volume, it brings up my dashboard. I did not spill anything on my laptop. It just started happening out of nowhere. I also tried restating and its still not working.
