MacBook Pro :: Crashes When Not Connected To Power?
Apr 29, 2012
Updated to OSX Lion. Now everytime I'm not connecting it to the power adapter, sooner or later the screen flickers and it crashes or freezes straight away. It's usually caused when I'm using the browser to open a flash site, which is probably heavy on graphic processing. Or watching a video on quicktime or youtube, even when it's not using a flash player on youtube. Or working on a graphic heavy processing apps like Photoshop. It's updated with latest software updates.

I've tried deauthorizing and reauthorizing the computer, deleting the com.apple.iTunes.plist file, restarting, connecting at different times... nothing seems to work. I've got the most recent updates on both iTunes and iphone. iTunes works fine on its own, but just gives me the spinning ball whenever I connect my iphone.

I have recently discovered that my MacBook Pro (2009) with OSX Lion does not go to sleep when the power cord is connected. It does not matter if I close the lid or select sleep from the Apple menu. All that happens is that the screen is powered off, the SIL is solid and I can hear the HDD/fan. I have not changed any of my power settings recently and it has not been a problem previously. If I disconnect the power cord the MB goes to sleep as supposed to (the SIL led starts flashing).Â
Doing some research I have found other users with somewhat the same issues when VMWare Fusion is installed. I have done some further testing and it seems that if I disable the virtual machine's Network Adapter and quit VMWare Fusion the MB goes into sleeping mode when the lid is closed even with the power cord connected. Enabling the Network Adapter again prevents the MB to go into sleeping mode when the power cord is connected. This even applies when the VMWare application is shutted down.Â
My guess is that the Network Adapter somehow prevents the MB to go into sleeping mode. The workaround is of course toggling the Network Adapter on and off but the virtual machine has to be running in order to do so. Not being that familiar with network settings on a Mac is there any other way to get around the problem?Â

Just want to make sure.
Because one of my adapter for the shaver is dead just by leaving it connected to the power outlet for 2 weeks.
I wonder what you guys do with your MagSafe Power Adapter.

My macbook has developed a problem where when the lid is shut and the power is connected it wakes up from sleep and then goes back to sleep and repeats this process every 30-60 seconds.
What's weird is it doesn't wake from sleep and get stuck in this loop when�the lid is open and the power is connected and I select sleep from the Apple menu�when the lid is shut and the power is NOT connected and is running from the battery
I recently updated my mac to Snow Leopard and put in a new HDD and since doing so the problem has been occurring.

My battery just went down to 7 percent charge even though it had been connected to the power adapter for quite some time. At least a few days. I didn't notice that the battery wasn't charging. Now it says it is charging again, but every once in a while I notice it has gone to not charging.Â

I recently bought a Macbook Air and needed some tips to keep it's battery healthy. Now I know that the battery has limited cycles before it goes down to less than 80% charge capacity. But if I keep my adapted connected as much time as possible, to reduce the number of those cycle counts, will it harm it battery? What is best way to keep the battery running healthy for long time - charging it once a day or using it with adapted connected most of the times?

My MacBook Pro 13" (Mid 2010) doesn't go to sleep, when I close the lid or when I try to activate sleep under the Apple menu. I haven't changed nothing in the system preferences. I already tried the following:Â unplugged all USB devices plugged and unplugged external display closed all applications (except of Finder of course) resetted all energy saving preferences deactivated bluetooth checked share options (everything is deactivated)Â
Then I unplugged it from the power supply and after I closed the lid, it went to sleep. Then plugged in power supply again and sleep didn't work.

Just got my new 2.8 with 5870. From the start it gave me some trouble getting it to turn on. I kept trying different plugs and such throughout the house and randomly I got it on. It was working good but I noticed that waking it from sleep the machine will click and the sleep light goes out and a red led behind the grill comes on briefly. I try pushing the power button to hear another click and the red led flashes. These problems seem intermittent and sometimes it will sleep fine. Im using 2 acer monitors connected via 2 vga-mini display adaptors.

I started to have problems with a used PowerMac G5 that I bought on December last year. The computer came with dual G5 at 2.0GHz, 8GB and 160GB Sata hard drive. The computer was running Leopard 10.5.8.
Once in my home I erase completely the hard drive and installed Leopard from scratch and ran software updates. At this point the computer was functioning good, sometimes crashes when I tryed to import images on iPhoto or Aperture, but appart from this nothing more. Few weeks ago I installed a new hard drive, the disk it's ok and doesn't give problems. The problems started two weeks ago, when computer crashes constantly and at any time with any reason, kernel crashes reports sometimes reports for Safari, other times for iTunes, others for uTorren, mdworker and mostly by Unknow application. I must to restart the computer by force shutdown, that only put thing worse. I was looking for documentation about solve my problem, but there is not so much responses.

I want to keep an old PowerMac G5 just for browsing the internet, etc. and I am about ready to install a wireless modem. Can I still purchase an AirPort card or Bluetooth capabilities to connect this computer wirelessly (and how complicated is this!), or will I still need to use an Ethernet connection to the modem?

I have just unpacked and connected my brand new 21.5" iMAC. When I hit the power switch on the bottom left hand side on the back nothing happens... I have checked power cord a number of times and no luck. One main question is - should the poweron button depress a much when I press it as I can feel no decernable movement/depression.

My G5 Power Mac Dual 2.0 run well. But I want to start the system from the dvd. Every time I try it, the mac crashed by starting up. On the screen you read. please start again.... If the Systems runs from Hard disc it runs perfect. And you insert the DVD, there is no problem. I tried two different System DVDs 10.4 and one 10.3. All run normal, but when I boot from it them the Mac crash every time. The same when I boot with "alt" and change to dvd start.

I have a G5 DP 2.0 and have been using it's built in ethernet port connected straight to my BT home hub (adsl/router) for years. Any way I add into the mix a netgear 1000Base layer 2 switch and the G5's ethernet doesn't work, reconnect straight to the router and all is fine. Now tested with new cables and tested on every port on the switch. By the way the port light on the switch don't light up when G5 attached. Now have tried the switch with a g4 and all is fine on every port and supprisingly I've stuck a PCI card in the G5 and that works as well. Just can't work out why the built in won't work through the switch but will direct.

I'm running a 400MHz Power PC G4 with 256 MB SDRAM and Mac OSX 10.3.9 on the net via wireless and it is SUPER slow. My Mac Geek buddy suggested I install a new hard drive (as it's only got its original 20gb hard drive) as it may increase the speed. Does this sound feasable? The Hard drive isn't full and the mac will only be used for net use as I've given it to me Mum.

I only ever want to use bluetooth when my Macbook is attached to a power supply (the 24'' cinema display power in particular, as my the Macbook is in clamsell mode and i want to use my wireless keyboard and mouse). Is there any way to automatically toggle bluetooth on/off when it is attached to the display. I tried to play with automator, and i found how to turn bluetooth on and off, but couldnt find a way to trigger it.

I've been fighting bad sleep crashes for over a year. Sometimes it would freeze when it started sleep, sometimes when trying to wake from a sleep. I've spent countless hours researching the problem, reading everything on the boards. I tried resetting the PMU, turning off Bluetooth, removing all USB, and all of the other suggestions. Nothing alleviated the problem. Last week I replaced the lithium battery on the mother board because it wasn't keeping the correct time. So far it is sleeping and waking perfectly for the first time in ages. No more freezes or jet engine fans. I have my fingers crossed. Power Mac G5 dual 2 GHz, purchased June, 2003

I try to open an exported Keynote '08 document.
Here's what happens: I create a Keynote '08 document and export it as Power Point. If I either double-click or try to open from within PPT '08, I get a crash stating that PPT has encountered an error and needs to quit. This happens EVERY time with EVERY single exported presentation. Oddly, it never happened in PPT '04.
Has anyone else had this issue?

My IMac crashes sometimes very suddenly, like in a power failure. It doesn't force quit or shut down, it just goes like somebody pulled the plug. It's usually possible to start it up again after 30minutes or an hour. The plug and lead seem to be fine. I tested it on another mac. The obvious suspicion would be overheating, but how can that be caused so suddenly (and how can I fix it)? It's an IMac Intel core duo, 20", 2 ghz, 2gb ram from 2006. I'm running Mac OS X (10.4.11) 2006.

I just bought myself an entry-level MBP 13". Coming from PB 12" 1.5 ghz, this is a major upgrade for me, and I am happy about it. However, there is one thing that I cannot figure out.
I have been a happy user of Dell 2209WA, which works perfectly with my PB. Today, I connected the monitor to my brand-new MBP via Mini DisplayPort to VGA adaptor. After connecting it, I closed the machine and woke up using my mouse. Immediately after that, the monitor said "Entering Power Saving Mode." I clicked the mouse, then the picture was sort of blurry. Then the monitor kept on entering power saving mode... As for the picture quality, even after I opened system pref. and detected the monitor, it was still not good. I'm totally bummed, because I really like the monitor.

Was activating FileVault on a new MacBook Pro until I received a message that it paused because it thinks the power adapter is not connected...even though it was. I unplugged the power adapter for about 12 seconds and then plugged it back in. But the error message persists. FileVault hasn't completed its process and not generated an encryption / recovery key. If I reboot do I risk being unable to access my Mac?

Why can't I hear my music keyboard when it is connected thru the Analog Audio line-in port? Looking at the System Pref. - Sound menu - in-put - Line in Built-in Audio, I can see activity on the input levels when I press the Kawai piano keyboard but no sound is heard. All other sound systems- I-tunes etc are operating properly.

I consider myself very good at all things Mac. But this one has me stumped.
I've just arrived home with a WD My Book Home Edition 1TB external drive. Formatted for Windows it mounted correctly via FireWire and USB.
First things first: I formatted it for the Mac... Mac OS Extended (Journaled), two GUID partition tables. So far so good. Each partition is recognized, each mounts like it should.
Time Machine then backed up my Intel iMac... again, everything's normal. No odd or unusual behavior.
Here's where things get strange.
For whatever reason I formatted the drive via USB. But my intention hereafter is to connect via FireWire... I need each USB port for peripherals.
But the drive isn't recognized through FireWire. I'm asked if I want to initialize it. When reconnected through USB the drive mounts again.
What's going on? Why is the drive recognized when connected via USB but not when connected via FireWire?

I have a late 2009 Mac Mini with 8GB of OCZ 1333 RAM and an Intel X25-M 160GB SSD. Running 10.6 fully updated and installed from scratch.I have been getting out of the blue crashes while the system is most of the times idle. Can it be the RAM? It's reported fine as 8GB 1333 DDR under the system info. The Intel SSD runs latest firmware.
This is the log from the last crash which happened a little ago.

The little icon on the lower right corner of my XP partition shows that I am connected to my internet, and the connection is very strong. But when I open up Firefox or Steam or AIM, it all says I'm offline and asks if I would like to connect. I tried restarting, repairing the connection, and almost everything else I can think of.

I have a 13" MacBook Pro and it is not connecting to the internet! Airport says im connected to my internet connection, but safari won't load the internet. I tried Firefox and still, the same result. I resetted the modem and the router, but still nothing. The internet connection on my other computer works fine. So I got on the Windows partition and it connects to the internet! So it's just OSX that won't let me connect cause my Windows partition works fine.
