I'm considering buying a used MacBook Pro (early 2008) from a seller on eBay. The seller disclosed "Sometimes the machine shuts down after startup" but adds that he does not know why.
Does this sound like something anyone has encountered and if so, was it serious?
My computer started to shut itself down without warning at around 10% battery power when my battery was bad. I bought a new battery, which works fine, but the problem persists. The computer does never tell me that battery is low or anything; it simply shuts down at 10% without warning and I can't seem to be able to do anything about it.
Info:Mac Pro
This started about 2 days ago, there was no apparent signs of such a thing going to happen.
My MacBook suddenly shuts down in the middle of my work. Shut down as in a sudden shut down, as if the battery was removed. There is no shutdown process, the whole screen just goes black. I've realized that this happens more recently when watching youtube videos, playing flash games etc.
Example : Computer dies in 10 minutes when watching videos/playing games. Computer dies in a few hours or NEVER when just typing, surfing.
It doesn't seem to be a battery problem. I've removed the battery and had my Macbook run on the Charger before, and it still died on me...

my macbook shuts off after initial start up

I have a late 2010 MacBook Air.Unfortunately, I'm in a country without an Apple store or any kind of official Apple support (no phone number to call).
2 days ago, I plugged in a little USB modem device (wireless is rare here) and my laptop shut down suddenly. It refused to restart at all until I did an SMC reset and then it was working fine (including with the USB modem plugged in).
However, the next day, the same shut-down occurred (when I plugged in the modem again) and now SMC reset is not doing anything. I've held down the start button for a very long time and there aren't any signs of life. The light on the charger shows that it is charging when I plug it in.

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.

I have a Macbook pro (OS 10.8.6), when I put it to sleep by closing the lid or explicitly choosing sleep option,it goes to sleep, but when I open the lid, the machine shutsdown. I have to press the power button for around 30 seconds to start the machine. In the logs I could find--Shutdown due to error code --79 and sleep failure shutdown.

View 1 Replies View RelatedIs it strange that my MacBook now just shuts down when it runs out of battery instead of just going into sleep mode? It's about two weeks old now. It used to go into sleep mode, but now it just shuts down once the battery is down. Also, I had the most wonderful experience with Apple. My first macbook (three weeks ago) had a small chip on the screen. When I finally noticed it, I thought it was a large piece of dust so it wasn't too terrible. I tried to exchange it at the local store where I purchased it, but it had already been four days and I had cut out the UPC for the printer and ipod rebate the day before and sent it out. So they recommended that I go see a mac genius and see if I can get the screen replaced because I could no longer exchange it or return it (risk losing my rebates).
So, a bit upset that I was too prompt about getting the rebates in, I scheduled an appointment with a genius. When I spoke to him, he just went to the back and got the manager. The manager said instead fixing the screen, he'd liked to give me a new macbook and instant reimbursement for the ipod and printer! (the rebates I sent in will be rejected since the mac has been returned). The new macbook I noticed has a much louder superdrive seems to be working hard every time the computer wakes up and when I open it, but that definitely beats a chip on the screen. But now it doesn't go to sleep after the battery gets low, but instead shuts off.
My Macbook shuts off immediately when unplugged and will not start up unless it's plugged in. This just started last night...I was using it while it was charging and then unplugged it when it got to 100%, and it immediately shut off. Prior to this, it seemed to be charging and running fine. It also runs fine plugged in.
I did some searching and tried some of the suggestions I found...shutting down, taking the battery out, holding down the power button for 5 secs, and replacing the battery...making sure the connectors were clean, downloading battery update, etc. Nothing helped. I also read an article about how the lithium polymer batteries will just quit suddenly like that instead of running down gradually. So I'm hoping all I need is to buy a new battery. But my question is this: Since the system profiler shows the battery health is "good," does this indicate something else is the problem? Or will it still show it's good after it completely dies?
Here are the stats according to System Profiler:
Charge Information:
Charge remaining (mAh):3955
Fully charged:Yes
Charging:No
Full charge capacity (mAh):3956
Health Information:
I am just now learning about these things, so apparently 1047 cycles is a good life for the battery. I just want to know that this is the only problem so I can order a battery and be done with it. Wish I could run it over to the Apple store and have them check it, but it's an hour and a half away, so if I do that, it'll have to be later in the week or next week. Naturally, I don't want to be patient and wait.
Upon hitting the power button, it got as far as the Apple logo screen (with chime), and then promptly powered itself down. 6+ subsequent tries have resulted in the same result; it never makes it past the boot sequence. We've tried resetting the PRAM and starting in safe mode, but we get the same result. It's also been plugged into the A/C adapter (and we've tried multiple outlets) so it doesn't appear to be a battery issue.

As soon as I unplug the power of my MacBook Pro, it shuts down, and all of my unsaved stuff is lost.
PS Is the battery user replaceable? I am using the Mid-2010 model.
