MacBook Pro :: Won't Start, HDD Spins For 5 Seconds Then Cuts Off?
Feb 18, 2010
I am trying to repair a macbook pro for a friend, I think it's the logic board, but I wanted to check with you all before I go buy one. When the battery is fully charged, I press the power button, I hear the hard drive spin for about 5 seconds then stop. The superdrive on it is broken so I can't try the restore disk. I ordered Pram, I am going to replace that. I tried two different hard drives and I know they are both good, I tried them in the macbook and through a usb port, and the same thing happened both times.

I'll cover the background to when this started happening.
I took my macbook out of an outer case to clean the shell itself.
I used wet ones which have alcohol so I wasn't worried, but also wasn't careless.
I once got a screen that said I needed to restart my computer. So I did.

I have a 30-inch cinema display and a Power Mac G5 (quad). Last night I was toying around by trying to boot an old 450 MHz G4 connected to my G5 via firewire ( I need to do some work on the G4 and it doesn't support my big display). So I connected it to my G5 via firewire target disk mode, then selected the disc (which has 10.2 on it) in the Startup disk preferences via System Prefs. Then I tried it and got a kernel panic. Alright, so it didn't work. Oh well. But now that everything is disconnected and my G5 is back to it's normal state (meaning the G4 isn't connected at all), when I start up, my display acts very weird. I get a few flashing colors blocks at the beginning, then it blacks out. Then when I login, it goes black again, then pops back on. So I'm trying to figure out what I did to my baby and how to fix it.

I have a Powerbook G4 17 that I have been working on. I recently replaced the screen and verified that it worked prior to buttoning it back up. When buttoning the powerbook back up, I nicked two wires with screws. One was part of the LCD wire that comes from the LCD itself. The second was the airport wire that is wrapped around the screen. I wrapped them back up with a cover and preceeded to get using my comp again. Once finally put back together, I could not get it to turn on.

I have two user accounts. On my one account (the main one) Safari works fine but on the other account just today it started loading real slow. then once it finally pops up with the home apple screen and you click anything, the wheel spins and spins for like 3 min then safari quits unexpectedly. When i click to report to apple and then send it, again the wheel spins for a long time and then it says it was unable to send to apple please check internet connection and try again. But, there is nothing wrong with my internet connection because if i switch to my other account internet works just fine!

So my girlfriend boss wanted me to fix her computer. So I brought it home turned it on, and it didnt chime but it booted to the gray screen with apple logo/ slashed circle/and folder with a "?" So I made a USB Mac OS x bootable drive (FLASH) held down alt (try using a windows keyboard its fun) was able to select option and install a fresh copy. all seemed well was running really hot so I poped of the screen. HOLY MOLY! this thing is CAKED with dust, and I am not kidding it has literally piles of dust. So I ran updates, and did firmware updates. Turned it off for the night. Â
The next morning I went to radio shack and got Dust remove spray, opened it up made sure I was carful taking off the screen, and blew the sucker out. now its NICE and CLEAN. then i made sure I plugged everything in and turned it on. Drive spun like normal, Optical checked for a CD, and fans are also running normally. but no chime, no nothing stays as silent as normal but doesnt budge, it is like it hangs. Â

I've got a strange issue with my PowerMac dual 1.8GhZ and I can't figure out where it's coming from.Last Saturday I experienced a Kernell Panic while using Safari and the Dictionary (MacOS 10.5.1).Since then, whenever I try to start my computer, it shuts itself down while the grey screen with the Apple logo is on screen. However, this isn't always the case:I can use my computer 'normally' if I press the option key at start-up and manually choose my startup disk.
I can boot from a Panther or Tiger installation disk, but not Leopard.If I try the hardware test the computer shuts itself down in the middle of the test.TechTool works and didn't find any issues with my computer. Nor did Disk Utility.I tried to erase both my internal hard-drives and do a clean install of Tiger, but the problem is still there (I have to press option at startup).I tried to reset the PRAM and Cuda/PMA. Doesn't resolve the issue.When I tick 'Restart automatically after power failure' in Energy Saver my Mac will indeed restart, meaning it thinks there was a power failure.Any idea what it might be? And why it only happens in certain situations?Do you think it's a hardware or a software issue?

After it bounces in the dock, It takes an additional 30 seconds for the window to open. I haven't done any updates or added any add-ons in the past few weeks, but this just started about a week ago.

I have a G5 iMac - 2.1 ghz, 20", 250gb hd and 3gb ram, but it has been having problems starting up and it is also going to sleep midway through a task or at random times totally unprompted.
It now almost never starts up first time (I keep the iMac mains power lead always connected and the mains electricity supply turned on at all times now)- sometimes I will get the 'Start-up Chime' and then the cooling fans start spinning very loudly and then after a few seconds the iMac stops the start-up routine, but often when I try to start-up I don't even get the 'Start-up Chime' and I have to leave it for some time before trying again.
I can also now only get the iMac to run as a Firewire Target Disc by starting up with the T key held down and then using an old G4 (400mhz) Powerbook Titanium as the screen/keyboard by using the iMac HD as the startup disc for the Powerbook but this is obviously just a temporary work around.
I have also tried backing up all my data, and reinstalling the Mac OS X onto the iMac but the iMac still will not start-up normal and I still have to use it just as a Firewire HD.

my macbook pro has started to just cut out randomly. I have had this with an expanding battery and haven't had the money to replace it yet, but I don't know if this is part of the issue. When my computer cuts out, it is as though the power cable has been pulled out and the whole system just shuts off in an instant. I know that the power cable has definitely not come out, though.

I am using a Mac Mini with a Realtek USB wireless dongle to connect to the internet. The software and drivers appear connected perfectly and i see the wireless utility and I can access my wireless network, which says signal strength 100%. I connect to it and it accepts the wireless key. Says connected. Then after a few seconds the connection is lost and it says 'Disconnected'. A few seconds later it connects then disconnects and this continues indefinitely but Safari never allows me to access any webpages.Â

I'm really interested in MB Air but it's little bit expensive toy for me. Do you think there are any chances for a price cut (after releasing the second generation)?

the display's started cutting off unexpectedly. It started a few months ago with random restarts, which I thought were caused by a bad hard drive, but it turns out permissions errors, stacked up over the years, really can bork your computer. I replaced the hard drive (didn't mind opening her up, since she's well out of warranty), but the problem kept occuring - only with the screen going dark randomly. I thought the new hard drive was dying, too. But here's how it's been going down lately. About twice a day, the screen will go black. Not just the backlight; it's as though the display has been turned off. I can't wake it from the display sleep, but it's not for lack of hitting the space bar repeatedly. Keyboard backlight stays on for a second, and then goes dark, at which point, I'll force a shutdown and try to restart. All of which is messing with my data; I've been doing a permissions repair pretty much daily now, and there's loads of 'em to repair. I noticed today, when it happened earlier, that my hard drive is still spinning, and USB peripherals retain their power. So what is causing my display to cut out like this, and how do I keep it from happening again (at least this frequently) until I can afford a new MacBook?Â

The audio on my macbook pro cuts out after a few minutes. It sounds like all the low end is removed. I still hear audio but it is MUCH lower and sounds filtered. I can barely hear it maxed out. Nothing attached (no external drives, no speakers, etc) and it's only a few days old.

I've connected my Macbook to my Samsung TV via HDMI and it works great!
I've been using the TV for it's speakers and screensaver so I'd like to be able to put on iTunes and have my slideshow play on the TV while I have guests over.
It works great, but if I don't touch the macbook for 20 minutes, the signal to the TV cuts out. The Macbook isn't going to sleep, because I've adjusted those settings accordingly. I feel like the TV is stopping the connection for some reason. As soon as I touch my macbook, it resumes playing and everything.

I have a fairly new 17" Unibody MacBook Pro, and recently my AirPort signal cuts off after about 30 minutes. I could just be on Facebook, and I will loose the signal after 30 minutes, and then I got to reselect my network. It becomes very annoying if when I try uploading videos to YouTube, having to start uploading all over about 3 times. I took it to the Genius Bar on Saturday, and they couldn't diagnose the problem, and they said they have to send it out to depot, but i can't afford being without my machine till June. I've tried restoring the default settings on my AirPort base station, but that didn't effect the problem. Could there be a problem with the AirPort card in my machine?

in the last week or so I've begun having a problem with the WiFi connection on my MBP. While using the Internet, web pages will no longer load, my mail client can't connect to the mail server, etc.When I use the terminal to ping Google or any other site, I get the message that the server can't be found.In the menu bar, the WiFi icon indicates a strong connection, but when I open Network Preferences, it says that WiFi is off.When I click, "Turn WiFi on," the menu bar icon goes to the empty fan icon but WiFi refuses to turn back on again.The only thing that I've found to work is to restart, and once or twice now that hasn't worked either.
One other thing I noticed was that this last week Network Preferences had identified my fitbit tracker USB syncing dongle as a network device and had added it to the list of devices on the left side of the preferences pane.This happened after I had already begun to have problems, and after I deleted the syncing dongle from the list, WiFi came back up again with no problem.This is a MBP with a 2.7 GHz i7, eight GB of RAM, running 10.7.4.Can you offer any solutions or suggestions for further troubleshooting?

I just tried to play a legit DVD and it won't play. It accepts the DVD, spins for a bit then spits it back out. I've tried several ones. All legitimate dvd's (not burnt ones) and none of them work. I've played DVD's on here before.

Here is what is going on with my MacBook:
-If I insert a music CD, the CD drive spins it and makes noise. It does not open iTunes or even show it on the desktop. It is not recognized. Then the computer ejects the disc.
-My iDVD software seems to have taken a crap. I am prompted every time the computer boots up that iDVD has quit unexpectedly and gives the options of "relaunch" "cancel" or "report to Apple".
-This is the weird part: I was going to reinstall Leopard OSX from the disc. The computer reads the discs and the "X" screen pops up. I then try to go through to reinstall the software as it tells me that it will restart.
It restarts and then ejects the disc when the Apple logo pops up. Therefore I cannot reinstall the software. Does this sound like a software or hardware problem? Can the fact that iDVD is not working mean that my CD's would not play? Does anyone have any ideas on what I can do here? I am desperate and would like to know what other approach I should take before I put a new drive in.
White MacBook, 2yrs old. 500gbhd, 4g RAM.

I installed the latest update 10.7.4. After the nice progress bar finished, I just get a nice Apple logo and a spinning wheel of death. Rebooting gives me a new progress bar and a new spinning wheel of death. OPTION-start does not really help, since there is no DVD drive on the MacBook Air Core2 to reboot from.Â

A while back I was running low on hard disk space so decided to upgrade my hard drive. Went ahead and upgraded to 320Gb. Then after some time, I noticed that the hard drive was making a large spinning noise so I thought it was a bad drive and RMA'd it. I just recently got the new drive and installed it and the drive was making that same loud spinning noise. Now I'm frustrated with this and want to get to the end of it. I'm thinking it might be the rubbers are out of place that holds the drive.

My hard drive crashed after about a year and a half. So I bought a new one and installed it myself. When I turn on my mac now and hold C with the install disk in the drive it just spins for a while below the apple and then goes to the gray please restart your computer screen.

I've just noticed trying to upgrade from 10.5 to SL that my Superdrive is acting funny. Anyone that's heard a superdrive knows that when you put a disc in the machine it spins up to a first "plateau" and then spins up to full speed. In my case, it spins up to the initial plateau and then spins down again. It will do this cycle maybe 3 - 4 times and then sometimes spit the disc back out. Occasionally it will continue this spin-up-spin-down cycle until I restart and hold the click button (eject does nothing). I am screwed (I'm just out of warrantee). Its a real shame - I use the optical drive so infrequently that I would never notice there was a problem until it's too late. This is a 2009 15" MBP, 2.66 ghz with 4gb ram running 10.5.8. I have a MATSHITA DVD-R UJ-868
