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.
I have a macbook mid 2007 that shuts down immediately after it is unplugged from AC. I've tried the battery on another machine and it works fine as well as trying a known good battery in this machine.Also I've tried a known good AC adapter. Other things I have done are run the hardware test which shows no errors, reset the smc and Pram, repaired permissions etc. the battery appears normal in the menu bar and says it is fully charged.Also it Appears in system information as normal.coconut battery also appears normal with 275 cycles.I'm hoping the problem lies in the Battery Connector with Sleep Switch and not the logic board. Anyone had any experience with this problem?
One other strange thing is that after unplugging the AC the system shuts down immediately, but once you plug it back in it starts without the power button being pressed.
I used Bootcamp to install Vista on my Mac Book Pro 2.4 Ghz (April '08). It has been working very well until Dec 2008. While running a PC game on battery, Vista operating system would just shut down unexpectedly. If the machine is plugged in, it would work fine. Currently the problem is getting worse; when I boot up into Vista on battery, it would shut down in about 2-3 minutes.
Initially I thought it was a battery problem. I booted up into Leopard and checked the battery information in System Profiler. I didn't see any problem. 332 cycles and condition is "Good." In addition, Leopard works just fine on battery.
I have a 3 1/2 year old Macbook, my Applecare has ran out. About six months ago my computer began shutting off immediately when unplugged. (Was letting my roomates use the computer, came home one day and it started doing this.) I believe that my battery is OK, it performs between 97% and 99% consistently. When I do the battery test, all of the lights light up.
I've read through the forums and it seems a lot of people are having this problem, but their batteries are bad. What are some options/solutions to this problem? I am willing to invest money wisely into the computer to keep it running smoothly for a while.
I hadn't been using sleep mode on my iMac G5 for a while (but it always worked previously to me setting it to "never"), and now yesterday when I turned the sleep mode back on, it has decided it wants to shut down instead of sleep. But it's not a nice shutdown...it just powers itself off, as if it was unplugged. It always boots back up with no problems.
I discovered my iMac shut down and to start. I feared it had been fried in an electrical storm the day before, though the whole house is surge protected, and a printer on the same plug was unaffected. I tried unplugging briefly, still no luck. I tried hitting the start button ( on the iMac itself, not the keyboard) a few times over a couple of days with no luck, and unplugged it in prepartion to cart off to a repair shop, fearing the worst. A couple of days later, I plugged it in for one last try before taking it to the car and, bingo, it started! Everything was fine, everything in its place.
A couple of weeks later, I once again notice the computer is turned off and will not restart. I uplug and replug - no luck. I unplug, let it sit, and try it again about 24 hours later.
Whenever i put mac macbook pro to sleep, it only stays sleeping for about half an hour and then wakes itself up. It does it whether i close the screen or manually put it to sleep. When its awake, the system is running but the screen is dark unless i click a button.
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.
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?
Information: PowerMac G5 dual 1.8GhZ Mac OS X (10.5.1)
My comp. has worked perfectly, Then I installed some updates, Itunes i think? And the comp. Shut down, and when it restarts it works for a min or two, then freezes, and i get the beach ball, that just spins around and around forever.
if I don't try to open anything, or do anything when i restart it, it will just shut down, and restart, then when it comes to the Grey screen with the apple and the little circle below it, the circle looks all pixilated, and just freezes
that is the version its on (Taken two days ago, and sent to a buddy for other reasons completely)
This has been a great computer - bought new in 2004. Recently started to click "off" as it was just powering up. I thought there was a bug - so did a clean and install for OS X - but still does it. The only way to start computer is to hold the Options & Alt key and P and R key at start up until I hear 6 dinging noises of start up (why six is the magic number I don't know. But it is the only combo that works!). Once it is up and running no problems.
My Mac attempts to start up and automatically shuts down on it's own. It continues to start and stop for several minutes and finally boots up. Once it's up it works OK. I've had it in to the Mac store and they tell me it's probably the power supply, but after leaving it on all weekend it seemed to work OK so they didn't do anything. After I brought it home it is still acting in the same way. It's only on trying to start up that it cycles through the start - stop action. Once I turn it off it's the same problem on trying to start again. Does this sound like a power supply problem?
when i start my imac it shows the apple logo, then the circle starts spinning and after a couple minutes it just shuts off. BTW i have windows on it as well so when i hold option it lets me open windows but not os
Recently my macbook pro battery stopped working, i took it to the apple service and battery has to be replaced which they will do so soon. They told me i can still use it on the power cord. However when i started it up the screen has a spinning wheel and a loading bar underneath the apple logo, which it never had before, and when the bar is 1/3 done the computer just shuts down every single time at the exact same place.

Fairly new MacBook Pro with OXLion. When I try to turn on the computer, the startup noise and screen appear (grey loading screenwith apple icon). A loading bar at the bottom of the screen fills about a third up, then the computer shuts down again.
My battery needed replacing for a couple of months before i dropped it from about knee level onto a sidewalk. After the drop I got the not charging icon. I thought maybe the battery had just finally died. so I did not panic about the no charge. The laptop works fine when plugged in to power with the old battery on or no battery at all. Not at all when unplugged.
When I put the brand new battery on the lap top, the computer shuts down halfway through boot up. I tried holding the power button down through boot up reset, as well as removing all power (plug and battery) and holding down the power button for 10 seconds reset.
When you unplug power from your MBP, the battery icon is supposed to show the battery level. Right now, mine shows the plug icon and if I click it it says power source is the power adapter. It's sitting in my lap not plugged in.
I usually use my laptop at a desk plugged into an AC outlet. Well I was going to be away for a week, so I unplugged it, when I came back, the battery went from 97%, not charging to 12% when I booted the laptop up again.
Also, can one continue using a macbook laptop if the battery is dead, but run it through or plugged into an ac outlet all the time?
I got up and tripped over the power cable and It popped out (thanks magsafe! ) but the computer immediately shut down. I plugged it back in and started it up to see my clock was messed up. I changed the clock and redid the update. Everything seems to be working now but I was just wondering if anything else could have happened?
last night I installed firmware 10.5.8 on my 2.4GHz Penryn MBP and ever since then, I am unable to use Wi-Fi when my computer is unplugged. When my computer is plugged in I am able to use Wi-Fi, but the second I pull out my power cord, it immediately stops.
I purchased my mybook 500gb external hard drive the same day I bought my mac. One day I accidentally unplugged it. Now when I plug it in into the usb hub, it won't pop up mybook icon on my screen. How do I get it to work again?
Every time that I unplug my MacBook it immediately shuts off. I have read similar stories but there is no black or red "x" on my battery icon. I have tried to take the battery out and put it back in but it didn't work. The light on the plug in is green and I'm not sure what is wrong.
