MacBook Pro :: Computer Shutting Down With No Warning?
May 23, 2012
I have a late 2006 MacBookPro, OSX10.5.8 . The machine will run fine on battrey power to a bout %50 or %60 and then just completely shut down. No going down to %20 or %30 and a warning etc ... This has only started happening in the last month or so. The battery is about a year and a half old, 198 cycles and shows about 3200mAh at full charge. I do understand the batteries in these things are only good for a bout 300 cycles. What I don't get is th lack of warning of any kind.
I have a 15 inch Macpro running Mac OS X Lion, version 10.7.3. It keeps shutting down without any warning. The screen just goes black and I have to press and hold the power button for a while till a hear a sound to turn the system off. This is happening like, more than 5 times a DAY.
When I shut down last night before my Mac went off, I got a big black box in the middle of the screen telling me to hold down the power key for a few seconds in 4 different languages. Did that and Mac went off.
"Warning your computer may infected" on a new tab popped up, and just recently Ive been having many popup tabs with random things on them. When I tried to exit the Warning page, I got the warning that I may have two trojans on my computer.
I just replaced my battery and now my computer shuts down randomly no matter how much battery power I have. Most recently it shut down with over 70% battery life. I followed the instructions on the new battery, but I can't figure out what is causing this type of issue based on my settings that didn't change from the original battery.
I was using my Mac (Macbook Pro 15" screen) and tried opening a file in GarageBand, at which point a warning message came up saying something about a midi file and something not being allowed, and then froze, resulting in me having to switch the computer off from the power button and restarting (Sadly I didnt realise that this would be the start of a whole host of problems and didnt make a note of the warning message). After rebooting I got the 'stuck on the blue screen with the Apple logo and infinitly spinning wheel' problem that i've seen in a few posts. having tried numerous suggestions posted with no change I ended up taking it to the genius section of an Apple store. When i got it back they said that it may have been a corrupted file, and that they re-installed and reset the starting programs (Something along those lines, I cant quite remember). I can now get onto the computer and use it, though some new problems have arisen.......
I have a Macbook pro 2.4Ghz Intel Core 2 Duo witch i bought before 1 year before 3 days it started to doing this problem: i choose shut down and instead of that it restarts. I did the command option P R thing to reset but didnt work also does that when im going to safe mode. i also try to clean install my operating system but still nothing happens the problem is there i did also a hardware test and everything is ok verify disk : ok permissions ok: i dont know what else to do?
I have a ibook G4 that's been randomly shutting down. It started doing this maybe about a month ago but it's started getting really bad lately. At first it would shut down if I unplugged the adapter. Not every time I unplugged it, but probably about 50% of the time. When I press the battery button all of the green lights would light up. About half of the time it will start up again if I just hit the power button but the half of the time I have to reset the pRAM. Lately this same thing has been happening except when the computer is still plugged in. And when in say shutting down I mean essentially instantaneously. One second it's on and then the screen goes black and it makes that turning off noise. Not a chime, but like all the fans and hardware are coming to a stop.
For the last few months, my MP has had a strange quirk. When I select Shutdown, the computer restarts instead. Then, at the login screen, I select shutdown and it will then turn off. I've tried disconnecting all USB and Firewire connections (except keyboard and mouse) with the same results. It does seem to be time related. For example, if I start up the computer, get to the desktop and then shutdown, it turns off no problem. However, after its been running for a bit it will do the restart thing instead.
For the past two nights, my iMac has randomly completely shut down. I set it to sleep before going to bed. When I woke up, it was shut down. And the weird thing is that it was shut down, and when it started up, no applications or anything were open. Generally, I'll shut down and it keeps everything open and running, then when I turn it back on, everything is where it was. I don't know if I lost documents or anything... or everything. I've never seen this before since getting Lion.
I checked my energy saver schedule... I had it set to SLEEP at midnight. But it is never set to shut down or start up. And even if it was, why are all the apps closing when it shuts down?
I don't know if this has been discussed here but all of a sudden my iMac, running Snow Leopard, 10.6.1) keeps waking up all on it's own. I believe this started after the latest update of Java and Super drive firmware (I believe these were the latest updates).
Is there anything I can do short of shutting the computer down.
I have a MacBook which has recently been shutting down when it feels like :/ this all started a week or two ago (well not the shut downs but other issues that I'll get too), basically the fan I think has been knocked as it is bumping the top or something as the whirring is getting loud and it sounds like every now and again it hits something
Also CPU usage seems to be averaging out at 20% for Safari and 100% for HD Video where as it used to be very small amount for Safari and 30 - 40% for HD.
I recently installed Leopard. On my way to bed I saw that there was an update to be installed. I clicked install, but the install took to long (and was being executed in a special screen after the shut down of the computer, so there were no annulation options) and I was so annoyed with the length of the installation that I shut my computer down. A big no, so it seems, because the next morning when I booted my computer, the login screen appeared. I set up-auto login, so seeing a login window was strange. When I entered my correct password, I first saw a blue screen and then returned to the log-in screen. There appears to be no way for me to log-in.
Things I've tried: safe boot, booting with the install DVD (I checked the harddrive for any problems, there were none) and booting while pressing an interesting variety of keys. With the same result: none. I tried doing the root-user thing, but to no avail. I think I don't have root user selected in finder. The updated I tried to install was the last one seeded by apple, I think it was the 10.5.3 update; there were three files to be installed. My computer is and intel iMac from the first quarter of 2007.
Last night my macbook air turned off without warning and wouldn't turn back on until I tried again this morning. A few weeks ago I had my battery and logic board replaced and since then it the screen has gone blue for a few seconds and then back to normal a few times, (in case this is related at all). Is there something I should do to make sure this doesn't happen again.
Now this didnt always happen but as of lately my unibody macbook runing Lion has been dying without warning that my battery is low. It doesnt even go to sleep, it completely dies.
I have a MacBook Pro, bought around two months ago.Recently I notice, it gives unknown sound like "Ding" and "Shung" when I am doing nothing with it (I am bad with putting sound in words).No new emails or messages from any softwares I installed.It happens even after I quit all the applications, and it's unpredictable.
I keep getting this warning that my disk is full, I am unable to download updates and even songs from iTunes. Also in the finder I apparently do not have any files because the my files section is blank. i have cleaned up the download folder and emptied the trash as well as performed a diskrepair. I tried to reinstall the software and was told again that the disk was full....What do I do?
When I'm working, sometimes it goes to sleep without any warning, also with a full battery. It never happens when the magsafe is connected. I noticed that when I wake the macbook again, in the battery icon (top-right), there is a "X" instead of it's capacity%.. Therefore I blame my battery for the random sleep. (the "X" dissapears almost immediately after waking up)
Here is a copy-and-paste of the console log: Code: 9/05/08 16:25:42 kernel System Wake 9/05/08 16:25:42 kernel Previous Sleep Cause: -60
When I let it go to sleep in a normal way, it says 5 in stead of -60. Does anyone knows the meaning of the -60? Google doesn't..
I bought a MacBook Pro September 2007, the last months I have experienced a sudden shutdown of it without any low battery warning. After browsing around the forums I found a app called Coconut Battery which I installed. This is what it showed me: What I can do to get my battery performance better? Do I have to invest in a new battery? And aren't the prices on those extreme?
