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.

MacBook :: New Unibody Shuts Down Unexpectedly When TOUCH The Power Cable

Mar 14, 2010

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

Sep 13, 2010

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?

MacBook Pro :: Unibody With "7 Hour" Battery - When Turn Wifi Off - Screen Down To 1/3 Brightness?

Feb 13, 2010

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?

PowerPC :: Ibook Shut Off After Re-installing OS X Now Won't Turn On?

Jan 16, 2009

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.

OS X :: ISight Light Won't Turn Off And IMac Freezes At Shut Down?

Jan 7, 2011

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.

Mac Pro :: Power Supply Not Working / System Shut Down Suddenly And Would Not Turn On

Jul 1, 2010

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.

IMac Intel :: Unable To Turn On System / Shut Itself Down And Refused To Power Back Up

Jun 19, 2008

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?

IMAC-Intel (Early 2006)
Mac OS X (10.4.11)

Intel Mac :: Won't Turn On, Get Message "must Shut Down" Before It Boots U

Jun 5, 2012

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

MacBook Pro :: Unable To Turn Off/turn On A Bluetooth?

Apr 14, 2009

I have a problem with my 17'' MBP unibody:

1) Bluetooth is ON:

I can't turn it off. The checkbox is inactive.

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.

MacBook Pro :: Can Any Unibody Take 1TB

Jul 1, 2012

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.

MacBook Pro :: Shuts Off Unexpectedly

Jun 4, 2014

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.
