MacBook :: Unibody Unexpectedly Shut Down / Won't Turn On
Mar 6, 2010
I have an aluminum macbook with a 2.4Ghz core 2 duo processor. I am the second owner, but I have owned it for about a year and taken good care of it. The other day I was browsing the internet internet and my macbook just turned off. It didnt give any warning or go through a shutdown sequence, it cut the power and turned off all of a sudden. I should tell you that it has done this once before, about a week ago. However, in that case I was able to turn it right back on without any issues. Now, on the other hand, I cannot get it to do anything. No chime, no gray screen. All that happens is the little white light on the lower right side flashes for a brief second. There is no screen activity, and as far as I can tell by holding my ear up to the hard drive it does not start to spin at all. I have attempted to reset the pram and smc, but I have no idea if it is resetting. It was not hot at all when it shut down, it had been sleeping and I had only just started using it. It was still cool to the touch on the case. Does anybody have any idea what could be causing this? I do not have the money to replace the logic board, so I am hoping it is something else.
I got my macbook during November of 2009 but two weeks ago it started shutting down by itself once I touch the magsafe of the macbook or remove the magsafe. All it needs is a simple touch and it shuts down. When it does shut down, the light indicator doesn't come on anymore. I have to keep removing the magsafe, and plugging it back in like 20 times until it starts charging again. So now I just let it fully charge every time I use it since any sudden movement will cause it to shut down. I will be making an appointment next week at the apple store because I had no time to go these past 2 weeks. I never dropped it and take good care of it. I am just wondering what might be the cause of this? I hope they do not take weeks to fix the mac since I have a lot of homework to do
My macbook pro unibody mid 2012 macbook pro won't turn on. I hear the DVD drive and see the indicator light. The screen is not on. I want to see if there is a fix. I can't afford a repair because I have no money.
Last night I was watching some videos on my computer and noticed that the fans were spinning, because it was pretty hot. Next thing I know the laptop just shut off. I didn't think to much of it because I just assumed the battery dided and needed to be recharged.
Well now I go to restart my Laptop and it will not turn on even with the laptop plugged in. Any ideas on what could be wrong? Is my laptop dead, what happened?
So everytime I try to turn my macbook pro off by clicking the shut down button it does the usual turning all software off and then going to the desktop with the dashbord going away and the little circle coming up but it just stays like that forever until I force it off by pressing down the power button. What should I do? I just got this laptop around 6 months ago

I was launching my sims game when I plugged in my portable charger in my MacBook Pro. As soon as I plugged it in, I heard a tiny poof and next thing I know the screen turned black. I held down the power button like I normally would and it wouldn't work. when I plug in the charger, there is a faint green light.
Recently my MBP (15" Santa Rosa) froze up. After having to force it to turn off it now no longer turns on. It will make the start up sound but it is very muted.
i have a macbook with osx and when i go to turn it off, all the icons disappear and i am left with just my desktop picture and that small little loading black thing. I don't what to do, i have tried waiting a long time but it never turns off, i usually end up having to hold the shut down button which feels dangerous to my comp.
What should i do... is it a virus or something else?
oh, and sometimes some of my programs wont shut down even after force quit.
I am seriously considering purchasing one of the new unibody MBP's with the new "7 hour" battery. Just a couple quick questions for you all: Do you get 7 hours when you turn wifi off, the screen down to 1/3 brightness, don't use the CD drive/etc, or does it actually last 6-7 hours in normal use (surfing web, screen really bright, backlit keyboard on)? Has anyone experienced a degradation in battery life after a bunch of cycles? I notice apple claims that the new battery will last 5 years, yet they don't warranty it for more than a year. That does not sound good to me. Opinions?
I bought an ibook a little while ago because I wanted a small, simple notebook and I love my home iMac. I found one for a good price on eBay and when it arrived everything seemed ok. I wanted to re-install the OS and set everything to my specifications because I was having a little trouble with some of the apps. Anyway, I went through the lengthy re-install and just as it finished counting down the seconds to completion, it shut down. I thought it might be in sleep mode because the little white light was on, so I hit a key and the light went off but nothing happened. Nothing on the screen, no HD noise, nothing. I'm at a loss because I really don't know much at all about hardware or software, which is why I liked the user-friendly Mac so much. The only thing that tells me it's getting power is the little green light at the power connector. I tried a PMU reset (there's no reset button on my model so it was a button combo of shift-ctrl-option-power I think) but that didn't do anything.
tonight I started having trouble with my intel iMac (running OSX 10.4.11). I'm having issues with two things (bolded for those skimming):
Out of seemingly nowhere, my iSight light turned on and now wont turn off. The only program I had open at the time was Firefox. When I try to open up PhotoBooth it says this:
There's nothing listed under USB High-Speed Bus in the system profiler either.
I've tried logging out of my user account, restarting, shutting down, unplugging and holding the back button for 5 seconds ...none of that worked. I tried resetting my Mac's PRAM and NVRAM. That didn't work either, and that's where a second problem appeared: when I try to shut my computer off, it freezes. I have to shut it off by holding the back button.
Is repairing the permissions and/or disk worth a shot? Or should I just take it straight into the Apple store? I hope it's not a hardware issue because I just recently had a new hard-drive installed after it broke down on December 15.
I used to just closed my Mac instead of pressing the shutdown button; I tried this time but I cannot shut it down anymore, also my keyboard cannot control the volume or turn on the keyboard-light. Also I remember there is like a back-up shortcut (or something like that don't know what is it exactly named) consisting of three keyboard button.
I tried the "search" box before making this thread. Would like to know if the power supply from a 2008 MacPro work on a 2006 MacPro. If anyone has tried this? My 2006 MacPro shut down suddenly and would not turn on. I use an APC UPS plugged on a power surge outlet. The Mac technician who examined the unit suspected it might be the power supply but Apple may not have in stock the power supply for the Ist Gen MacPro.
I have a 20" intel-based dual core Mac which i have had for about since early 2006, i haven't had any big issues with it until a few days ago when it suddenly shut itself down and refused to power back up. I ran through the checklist that Apple Support provides, including resetting the SMC by unplugging everything and waiting 15 seconds or so but none of it worked. Eventually I just left the power cord unplugged overnight and in the morning I plugged it back in.
After having the power cord plugged in for a few hours and the machine turned off, i tried pressing the power button again and to my amazement it powered back on! Immediately i ran the TechTool Deluxe software that came with my extended protection plan (now expired) and everything was fine. Later that night however, I had left my computer on for a few hours before returning to it and realizing it had shut itself off again. Now I am back to where I started, going through the checklist provided by Apple and am really starting to get concerned. Does anyone know of anything else I can do, short of taking it in to an Apple store? Or is something needed to be replaced?

I just got a Early 2011 Macbook Pro 15" i7 that has a broken scissor for the "x" key (I still have the black "x" key itself. Would the scissors from an late 2007 Macbook Pro 15" be compatible (I've got an old dead keyboard for it that had coffee spilled on it)?
My wife's iMac (about 4 years old, OS is pretty up to date) won't boot up. I turn it on, get the apple logo, gray-ness "curtains" down and I get that yucky "you must turn your computer off by holding down the on button" (or someting like that) in several languages.
Tried these, none worked:
(1) -Shut down your Mac -Disconnect the power cord -Press and hold the Mac’s power button for 5 seconds -Release the button -Reattach the power and boot the Mac as usual
(2) -Shut down the computer.
-Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously.
-Turn on the computer.
-Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
-Hold the keys down until the computer restarts and you hear the startup sound for the 3rd time.
-Release the keys and let your system boot up.
(3) -Power the iMac off -Power your iMac on and hold down the "Option" key -Choose your internal hard drive (Macintosh HD) and boot up your iMac
But I can turn it off, if I choose "Share my internet connection for other units". (I don't know, if this is the right text in english, because my OSX is in german)
2) Now Bluetooth is OFF:
But I can't turn it on, because the checkbox "ON" is inactive.
It turns only on, if I choose "New Unit"(?). Then there is a new window, that says, that this is only possible if Bluetooth turns on. If I say OK, bluetooth turns ON.
Back to 1)
What's the problem. Why is this f* checkbox for turning bluetooth on and off inactive?
This is not a hardware problem, because I can have stable bluetooth connections.
I did a smc and am pram reset. But it doesn't help.
I am getting a pop up "Are you sure you want to shut down your computer now?".
The one we get, if pressed the power button to switch it off?. The problem is not consistent and mostly I get if left inactive for some time(random). I have run the hardware test(installer DVD and pressing D) without any issue found.
Have Word 2004. Don't laugh; it's been working. When got new MBP, Office worked. (Well, can't recall if PPT ever worked with it.)Excel and Word definitely did work. Two weeks ago, Excel started working sporadically, then not at all.Right now(!!), Word suddenly stopped working. "Word quit unexpectedly" and "Excel quit unexpectedly."
I have read in at least one place in the forum that "any unibody macbook pro can take up to 1TB hard drive". As someone who has upgraded Dells and Thinkpads in the past this would make sense, i.e. Any hdd with same dimensions, access method (SATA?) and same spin speed would be supported.
The reason I ask is that I called Apple UK to have a family member's late 2009 13" unibody upgraded at an Apple store. Apple UK do not undertake hardware work and they directed me to a central London office who do their official repairs, and they said if the max capacity of that model when originally produced was 500GB then anything bigger "might use too much electricity". Would not upgrade beyond 500. Offered me £300 for the old one in exchange for a new mbp. As far as I was aware the bulk of the power drawn was down to spin speed not platter density. Upgrading from 320 to 500 is hardly worth their fee so it looks like a home upgrade.
As of a few days ago my MacBook Pro has been acting oddly. When I shut the clamshell and reopen it again a few minutes (or hours) later it's hot and makes sounds as if it is working hard at something but the display will not turn on. I usually end up turning it off anf then on again via the power button. I have a wireless keyboard attached due to damage to the laptop's own keyboard, but use the laptop's power button (which still functions). I've reattached, and reset, the keyboard a few times in case that was the problem but had no luck. It doesn't hinder my usage of the computer once it's on again but it is strange.
