My MacBook Is Very Problemic Power-Wise

At random instances in the time I've had my MacBook
(since September), I shut my MacBook down, but when I
close the lid the sleep light goes on, and the
battery runs dry. The only way I'm able to turn it
back on after one of these instances is by removing
and putting the battery back in. Needless to say it
annoys the crap out of me.
If you are pressing the power button and shutting the lid as soon as the screen goes dark, you may be putting it to sleep in the middle of shutting down, which makes it go into a state of neither proper shutdown nor proper sleep.

Even worse, since about a week ago, my computer will
turn off in the middle of me using it. It then takes
three to five attempts for it to turn back on and
boot up.
Does this happen on battery only or also when plugged in? Some people have battery issues where the machine will shut down without warning while still showing 25% charged or so. Mostly this seems to be getting solved by replacing the battery (unless it's simply due to not having the battery calibrated).
There were some earlier issues with spontaneously shutting down that were mostly solved by a firmware update.

Very strange power problem...

Hey guys (and girls ofcourse),
I'm having a very strange power problem with my late 2007 2.2Ghz santa rosa macbook.
Can you guys help me determine what the problem could be?
Here's what happened prior, when the macbook was still working. I got home from work, plugged my adapter into the wall, and it started charging. I left it on the table, and when I came back from the diner table I continued working, but suddenly noticed my macbook wasn't charging anymore. (the orange/green led wasn't lighting up but i was able to work on battery power)
I thought it was the poweradapter, so I went to the apple store the next day to lend one to test it. That didn't work, so it's not the adapter.
So then I started thinking it must be the magnetic DC connector. So I ordered that from the guys at ifixit, (since it's out of warranty) but I replaced it and it's not working.
I don't think it's the logic board, because I was able to continue working until I ran out of battery power. And I also don't think it's the battery connector, because if i'm not mistaking, the macbook can run without battery as well, but mine can't anymore.
Now I can't get any life out of my mac anymore...
Might there be something I overlooked?
Any suggestions are definately welcome!
Thanks a lot.
Timo from Belgium.

Hi Timo,
I think i have the same problem, my mac is not working without battery in it. and it wont charge it.
i wrote a post here http://discussions.apple.com/thread.jspa?threadID=2105648&tstart=0

Hi there Rlong50,
You may want to try force closing all open apps and resetting the device as an initial troubleshooting step. Take a look at the articles below for more information.

You may want to try this.
Solution A
Start up your MBP while pressing Option (alt)|, Command, P, R until your hear 3 chimes rather than 2 as indicated by apple. This worked for me the first time.
Solution B
Start your MBP while pressing Option (alt), Command, S
Hold until you see the computer automatic routine. When it finally stops type the following followed by "return":
fsck -fy
It will probably indicate some problem related to "pcscd.pub" (should be 16 instead of 17). I haven't figured out what this means but somewhere in the Internet i read it is related to scan cards...
More importantly this routine will fix any problems with your HDD similarily to disk repair. When it ends, it will tell you if it has fixed/modified anything. If it has, run the routine again by typing again "fsck -fy"
Lastly, reboot by typing "reboot" (followed by "return")
Solution C
Start up your MBP while pressing option (alt), command, S
hold keys until you see computer commands scrolling
when the routine stops type the following, each line followed by the "return" key:
mount -uw /
chmod 775 /
chmod 1775 /
reboot
After which your computer should reboot on it's own.
Each of the above has worked for me at one time or another. Once your computer has rebooted from the DVD you can reinstall OS X. If your problems started after installing 10.5.6, then I don't suggest updating until 10.5.5.
I'm very very disappointed with my 2007 MBP, it started to give me problems after 1 year. had to change the HDD and lately when I isntalled 10.5.6 it suddenly refused to start up., My previous Mac laptop (2003 866Mhz) worked for 4 years without a hitch. Ironically I've had to use it to access the internet and find solutions for my current MBP.
best of luck

Has your Macbook Air overheating problems been solved?

Hi All,
Has there been a solution to the Macbook Air overheating problem for you?
I'm considering selling my MBA but want to see first if there has been any new updates on this issue.
I have a Macbook Air with the specifications as follows:
Model: MacBook Air 1.6GHz Intel Core 2 Duo
Production year: 2008
Production week: 15 (April)
OS X Version 10.5.7
Have had the computer for about a year now and it has been constantly overheating and becoming more or less unusable when doing so. Have been hoping upgrades to the software would solve this eventually but that does not seem to have happened.
As I'm writing this room temperature is about 20 degrees celcius. Laptop sits on a table with power cable plugged in. Not running any external screen. There is no video streaming or music playing. Only the Firefox browser and a few more idle apps are active such as Mail and Skype (in the background). Even under these conditions the fan is currently running loud at 6100rpm and the Macbook Air is very hot underneath.
CPU temperature is currently 54 degrees Celsius. Both cores seem to be active.
Now, as an experiment I will head over to YouTube to watch a video and open up Microsoft Word in the background, a perfectly normal usage for a computer this new. This is what happens:
The computer starts to become painfully slow. After for example clicking an item in the browser there is a 1-3 second delay before the click actually becomes effective. It's now so hot underneath that I would not want to keep it in my lap. It is hard to use the mouse pointer properly as it does not update in realtime, I have to assume where it will land based on my movements. When scrolling, the spinning wheel icon becomes active. Everything is now happening in slow motion.
Video is lagging heavily. I can only see probably 1 out of every 10 frames or less of the video. All applications running are very slow. CPU temperature is now 64 degrees celsius. Fan is at 6200. Computer is now unusable for me. When I scroll a page in the browser it takes about 2-3 seconds before anything happens. Changing tabs takes 5-6 seconds after I click them. I will have to shut it down before re-starting and resuming work. When room temperature is even higher on a hot day needless to say everything gets a lot worse quicker.
Is this normal for Macbook Air's? If that is the case they are more or less unusable for most types of normal 2009 year usage (video, audio, browsing, office work etc).
What solutions have you found? Coolbook? Software/Firmware updates? Hardware changes? Please let me know if you have been able to make your MBA not overheat under normal usage.

Hi Everybody,
Thanks for your replies to start with.
I have tried to install Coolbook now and has it running. When using 'throttling' and letting it change CPU speeds (I think..) the problem still remains. When watching a video or other demanding task the temperature goes way up. Running a CPUTest (small or big) gets CPU temperatures of up to 84-85 C. Fan of course at 6200rpm all the time.
Right now, I have Coolbook set to 800Mhz and 0.9V. Apps running are Firefox, Skype, Mail and iTunes with no audio playing. CPU temperature at 56 c and fan speed (as usual) at 6200rpm. I can use the computer now. It is still lagging and not very fast at all. Sometimes text appear 1-2 seconds after I have written it on the keyboard.
So Coolbook has made a difference for me, but only when putting the CPU speed down to 800MHz. I wouldn't call reducing the CPU speed to half a 'solution' though and will not keep that as a long term solution. Reducing voltages for higher CPU-speeds 0.9875V for 1600MHz does not work, it still heats up massively.
Have used the MBA for the whole day today and can't recall a single time the fan has not been around 6200rpm except right after boot.
Thanks for the tips on upgrading to 10.5.8. I will try that right away and let you know how it works out.
Have also considered buying some cooling device but just as you say that feels like a bit of a last thing to resort to.
I'm surprised Apple hasn't responded stronger to this. Had this happened in the car industry we would have seen thousands of cars being sent back to the garage to be fixed.
If this only has to do with some specific production weeks then the right thing to do would be for Apple to let those people have their computers either fixed or replaced.

I have a MacBook pro that has power issues and will not start but the hardrive is fine. I do not want to lose all of my files so I was wondering if it's possible to transfer my hardrive from a older Macbook pro to a new one if I were to purchase a new one? Also, the software is not updated as the computer hasn't worked for about 2 months.
Also, if it is possible to transfer the hardrive, would my iTunes music transfer as well? It is not saved in the cloud.
Thanks for your help, it is much appreciated.

You computer is probably perfectly repairable, but if you want a new one anyway, it is perfectly possible to transfer the data from the faulty one.
But it would be a mistake to simply put the old HD in the new computer.
These are the steps:
Remove Hard drive from faulty computer. (very easy on Unibody MBPs, do-able but not so easy on older MBPs)
Put it in a cheap enclosure
Connect it the new computer
Boot up new computer.
If the new computer has never been run before the Setup Assistant will ask if you want to import your apps, data, settings etc from either another mac, another HD connected to the Mac or a Time Machine back up.
Obviously chose the second option (another HD connected to this Mac) and follow prompts.
If the new computer has already been run (so Setup Assistant doesn't run when you boot it up), you will need to use Migration Assistant...or run the installer again so that Setup Assistant runs again.

My macbook is very slow

my macbook is very slow, what can I do about it?

Things You Can Do To Resolve Slow Downs
If your computer seems to be running slower here are some things you can do:
Start with visits to: OS X Maintenance - MacAttorney;
                                  The X Lab: The X-FAQs;
                                  The Safe Mac » Mac Performance Guide;
                                  The Safe Mac » The myth of the dirty Mac;
                                  Mac maintenance Quick Assist.
Boot into Safe Mode then repair your hard drive and permissions:
Repair the Hard Drive and Permissions Pre-Lion/Mountain Lion
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
Repair the Hard Drive - Lion/Mountain Lion
Boot from your Lion Recovery HD. When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Restart your computer normally and see if this has helped any. Next do some maintenance:
Suggestions for OS X Maintenance
For situations Disk Utility cannot handle the best third-party utility is Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger. These utilities have limited or no functionality with Snow Leopard or Lion and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems. For more about malware see Macintosh Virus Guide.
I would also recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc.
For emergency repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. There is no confirmation that this version also works with Lion.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
     1. Carbon Copy Cloner
     2. Data Backup
     3. Deja Vu
     4. SuperDuper!
     5. SyncTwoFolders
     6. Synk Pro
     7. Synk Standard
     8. Tri-Backup
Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
Referenced software can be found at CNet Downloads or MacUpdate.
Additional Hints
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
Check for applications that may be hogging the CPU:
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time, then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file.

MacBook Pro suddenly loses power, returns after a few seconds

Hello,
I have an issue with my MacBook Pro, in that it sometimes (once or twice a day) completely appears to lose power. The screen goes black, and also the keyboard illumination goes out. It looks like a complete loss of power. However, after a few seconds, the machine can be awoken again, and nothing has been lost. The only thing I have noticed when this happens is that the wifi connection seems to sometimes - but not always - drop.
Could anyone help me is to what could be the problem? My previous MacBook had a problem with the screen connection, but given the keyboard lights going out it has the impression of a power or sleep issue.
Thanks in advance.

HELP! My Macbook Air won't power on!!

I have plugged it up and the power cord's light is green. It has ben a week and it still won't power on. What do I do now?

Were you able to find a solution... My wife's Air is doing the same thing I have tried all the KB suggestions of key combinations etc.. The power supply is green but the Macbook Air will NOT power on. Frustrated because I have a Dell laptop and never have had any problems as this Mac. So far she has had the Hard Drive fo so we replaced with a SSD $145... Then the hinges went $150... Then the LCD went $150 now it will not power on... from the looks of things it could be the Logic Board $850. There is no way I am sinking more money into this inferior product... I think Apple should be replacing this free of charge...This was all after the warranty was up...
Let me know if your problem has been resolved...

My MacBook Air has problems connecting to a saved network when I first open it.

My MacBook Air has problems connecting to a saved network when I first open it. When it idles, the connection gets lost and even clicking on the network won't connect it. Then I have to turn off wireless and turn it back on for it to connect. My boyfriend's MacBook Pro does not have this same problem and this problem started maybe 2 months ago and nothing about our internet or router has changed, and its only my computer having the problem. Its a 2013 MacBook Air and my softward is: OS X 10.9.1 (13B42). Please help!

Hello, nheredia05.
Thank you for visiting Apple Support Communities.
There are a couple steps that I could recommend trying. Power cycle the router and test to see if the behavior persists. Next, try an remove this prefered network from your list and then add it back again. Make sure all firmware updates have been processed on the router side and the settings have been optimized for performance. If the issue still persists try the steps in the second article.

Macbook pro goes into power save mode with dell sp2208wfp monitor.

I have a macbook pro and am trying to connect it to a dell sp2208wfp monitor, I am using a hdmi cord and it goes straight to power save mode. My mac works on my roommates monitor and his PC works on my monitor but my mac doesn't work on my monitor. I've read the other forums and have found nothing. One guy suggested plugging the mac into a power source still nothing, any solutions before I try and sell this thing on craigslist?

Had the same issue a few months ago when I tried connecting to external monitor, it is only possible to run external displays from a Macbook Pro while the power cable is attached, if you try and connect to external display without having the charger attached the external display will flash your desk top for a second and then your Macbook Pro will go to sleep. Hence connect your charger every time you wish to connect to external display, its not a problem with your Macbook Pro, it's just the way of Apple. Hope that helps.

Hi, my MacBook Air is not working anymore if it's not connected with the power cable. It's pretty new so I can't imagine that the battery is dead already. Why can't I use my MacBook Air without the power cable even though I charged it for hours?
