MBP dies when I unplug power cord

Anyone have any ideas? The battery wasn't in the best shape, it had "check battery" for about a year now.
Of course, Apple refused to do anything for me, as it's out of warranty. Until last week I was getting maybe an hour out of it. But ever since upgrading to 10.5.7 last week, as soon as I disconnect the power-cord, 1 sec later, the laptop just dies, requiring a reboot.
Tried resetting PRAM and the PMU/SMC. Reinstalled 10.5.7.
Here's the bat info:

Why did you wait so long for help?
Try the following:
HD/System/Library/SystemConfiguration & look for a file called batteryupdater.bundle. Select Get Info for the file.
If its version number is 1.2 or 1.3 you should be fine If not, or if you cannot locate a batteryupdater.bundle file (by using Spotlight, searching manually or using a 3rd party search feature) then download an update from Apple's website & install it. *If installing has no effect, you probably need a new battery.*
Your battery may be replaced for free. Take your computer to an Apple Store. _The staff will be able to check to determine if your model MBP qualifies for the free battery program._
MacBook and MacBook Pro Battery Update 1.2 Or you can take your case up w/Apple Customer Relations - 1-800-767-2775.

Macbook shuts off instantly when I unplug power cord.

Hello everybody.
This afternoon while I was watching a movie on my macbook, (it was on battery power, about 3/4 full) it just shut off. I could not turn it back on, so i plugged the power cord back in, it turned on fine, but whenever I unplug it it shuts down, even though it recognises the battery and charge level and all.
The thing is, when it shuts down it's not like if there was no battery, the screen dims, the battery icon changes to the one it has when its on battery power, and about 1-2 seconds later everything just shuts down. I'm just out of warranty (about 2 weeks ago). Do you guys think this is a hardware issue? I've gone through all the updates i have found on batteries and even reset the power management thing (where you turn the computer off with no battery and hold the power button).
Thanks for any help

After reading and resetting everything with Keyboard I still get blank white screen. The only way I can boot to Mavericks is unplug power cord, push and hold power button while plugging power cord in. Fans at full speed.

After reading and resetting everything with Keyboard I still get blank white screen on 2nd? page of boot. The only way I can boot to Mavericks is unplug power cord, push and hold power button while plugging power cord in. Fans run at full speed, machine boots then runs normal except the dvdrw will not . The mid 2011 IMAC had the same problem with LION. I changed hard drives, formatted, and installed a clean install of latest os x mavericks. Any help would be greatly appreciated.

Use the uninstaller provided with the Sophos software. You can uninstall CUDA via the preference pane. Be sure you remove the com.nvidia.CUDA extension which is located in the /System/Library/Extensions/ folder. Not sure if Fan Control has an uninstaller so you will have to do it manually:
Uninstalling Software: The Basics
Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash. Applications may create preference files that are stored in the /Home/Library/Preferences/ folder. Although they do nothing once you delete the associated application, they do take up some disk space. If you want you can look for them in the above location and delete them, too.
Some applications may install an uninstaller program that can be used to remove the application. In some cases the uninstaller may be part of the application's installer, and is invoked by clicking on a Customize button that will appear during the install process.
Some applications may install components in the /Home/Library/Applications Support/ folder. You can also check there to see if the application has created a folder. You can also delete the folder that's in the Applications Support folder. Again, they don't do anything but take up disk space once the application is trashed.
Some applications may install a startupitem or a Log In item. Startupitems are usually installed in the /Library/StartupItems/ folder and less often in the /Home/Library/StartupItems/ folder. Log In Items are set in the Accounts preferences. Open System Preferences, click on the Accounts icon, then click on the LogIn Items tab. Locate the item in the list for the application you want to remove and click on the "-" button to delete it from the list.
Some software use startup daemons or agents that are a new feature of the OS. Look for them in /Library/LaunchAgents/ and /Library/LaunchDaemons/ or in /Home/Library/LaunchAgents/.
If an application installs any other files the best way to track them down is to do a Finder search using the application name or the developer name as the search term. Unfortunately Spotlight will not look in certain folders by default. You can modify Spotlight's behavior or use a third-party search utility, EasyFind, instead.
Some applications install a receipt in the /Library/Receipts/ folder. Usually with the same name as the program or the developer. The item generally has a ".pkg" extension. Be sure you also delete this item as some programs use it to determine if it's already installed.
There are many utilities that can uninstall applications. Here is a selection:
    1. AppZapper
    2. AppDelete
    3. Automaton
    4. Hazel
    5. AppCleaner
    6. CleanApp
    7. iTrash
    8. Amnesia
    9. Uninstaller
10. Spring Cleaning
For more information visit The XLab FAQs and read the FAQ on removing software.
Be sure to remove your two Login Items. Finally do this:
Reinstall Lion, Mountain Lion, or Mavericks without erasing drive
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.
Repair
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. When the process is completed, then quit DU and return to the main menu.
Reinstall Lion, Mountain Lion, or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
     Note: You will need an active Internet connection. I suggest using Ethernet
                 if possible because it is three times faster than wireless.

Macbook Pro: both external screens go off when unplugging power cord

Hello!
I have my Macbook Pro set up with two external screens one connected thru HDMI and the other with Thunderbolt, I keep the lid always closed. I always have the power cord plugged in but when I for whatever reason unplug the cord both screens go dark and don't seem to "wake up" anymore. When I plug back in the cord I have to open the lid first to make the login window appear but after login my screens are switched. When I close the lid again it goes back to my original set up. The same when I turn on the Macbook and don't close the lid after it right away, the screens are switched until I close it.
Any idea on this?

As this article points out, there are very stringent requirements for using a MacBook in "closed clamshell" mode. #1 is to have the power adapter plugged in:

PB freezes when unplug power cord from laptop but not power outlet

Hi. Been having a dilemma with my PB for awhile. When I unplug the power cord from the connection in the PB, my laptop will work fine for a few minutes but always freeze at some point. By 'freeze' I mean the cursor will not move and the keyboard, trackpad, etc will not respond at all. I can restart it and continue to work until it will (always) freeze again. Strangely enough, if I unplug the power cord from the wall outlet but leave it in the side of the PB, I don't have any freezing problems. I'm not that savvy with Apples yet since I made the switch but I've tried resetting the pram thing but to no avail.
Any suggestions?
Thanks!

IBook screen goes black after unplugging power cord

I originally posted this topic in the wrong discussion group for iMac G4, the computer is actually an iBook G4.
My wife's iBook bought about 2 years ago shows battery 100 percent charged. But when she unplugs the power cord the screen goes black. Can not be restarted until she plugs in the power cord. It seems like it might be the battery. She got extra batteries when she bought it. Is there a way to tell if it is the battery before having to replace it?

Did you check on the status of your battery using "About this Mac" under the Apple on the menu bar? Click on "More Info..." and select Power under Hardware. It will tell you capacity and cycle count.
You may have a dead battery.

When to use Power cord...

Should I keep my Mac plugged in with the power cord or is it better to only charge it when the battery life is low. I have heard before that its not good to leave the charger plugged in all the time. or does that not matter.

If you keep it plugged in, it will prevent the battery from gaining excessive cycle counts, which can be a determining factor of a batteries lifespan. However, cycle count is a highly debated topic because there is no perfect evidence for either argument. At any rate, it's probably best to keep it plugged in, if you let the computer under 50%, plug it in, if you wait till it gets too low and plug it in it will generate more cycles. I keep mine plugged in most of the time, unplug occasionally.

Black screen when plug the power cord

Hi..
yesterday I bought a new laptop : hp 15-r138
When I plug the power cord - or unplug it .. the screen turn black for a second and then goes back to normal ..
Is this OK ?
Thanks

I've heard of this. Where when you do the update, if you let the screen go dim, or something you can't get it back because you can't see anything due to those controls running in the background at this stage of installation. I'm pretty sure you need to plug it into an external monitor to get it back maybe?

Radius sleeps after unplugging power cord

After my Radius is fully charged, when I unplug the power the laptop will immediately sleep. When I wake it up, it runs fine for hours on battery, as expected. Why on earth does the laptop sleep when unplugging the power?
It's really inconvenient because if I'm playing music while it's charging the music stops when the laptop goes to sleep after I unplug it!
I cannot seem to find the right series of options in the power control panel to prevent the laptop from immediately sleeping when I disconnect the power cable.
Please advise.

If you can't solve your issue and no one in the community can help, contact support to speak with a tech support agent at (800) 457-7777.

MBP random shutdown even with power cord plugged in

My MacBook Pro (original) has now randomly shut down 5 times since I installed 10.5.6 the week before Christmas. 4 of those 5 times happened with the power cord plugged in, the green indicator light on and the installed battery fully charged. I have two batteries and it has happened with each of them at least twice. Yesterday I got my first shutdown while on battery only. After each shutdown I was able to restart the computer and it operated normally, even the one on battery only.
These shutdowns are fast and complete. There is no warning of any kind. The screen just goes blank. It is not sleeping, there is no pulsing light on the front. Using the start key begins the process from scratch with the Apple "startup chime."
The occurrences have gotten more frequent. The first two were within 24 hours of when I installed 10.5.6 and they happened within several hours of each other. Both of these were with the power cord attached and fully charged batteries. I swapped the battery after the first one. When it happened again, I swapped them again.
The next time I had the problem was 1/30 (last Friday). The only significant software installation I had done between installing 10.5.6 and then was to install iLife '09 on 1/28. All software updates had been installed in a timely manner. Friday the laptop was plugged into external power and the battery was fully charged, but I don't know which battery was installed.
2/1 I had an issue where my computer couldn't locate the OS file on startup so I did a archive and install. It operated normally since then until yesterday, 2/4 when I had two shutdowns. The first I had the computer on external power and a fully charged battery. The second was the ONLY time I have had the shutdown occur while on battery power only. I was on a flight when the second shutdown occurred. I had used all the power in the battery that was installed when the first shutdown happened (down to about 11 minutes remaining). I then swapped batteries without shutting the computer down. The system rebuilt itself normally and I began working on iPhoto. About an hour later it just shutdown. I was able to restart the computer normally and used it for another 45 minutes or so before I shut it down for landing.
I called Apple Care this morning and they advised me to get an appointment with a Genius. I resist being without my laptop but will try this and let them look over the console log to see if they can find anything.
I have done all the basics, reset the PMU, zapped the PRAM and repaired disk permissions. The next thing I am going to do is to calibrate both batteries. I doubt this will have any impact on the issue because most of the shutdowns have occurred with external power connected. I just haven't done this in a while.
Any ideas out there? Anyone have a similar problem?
I have another issue on my Mac Pro since installing 10.5.6 and my wife's iMac G5 has a completely different issue since installing 10.5 (I didn't install this OS until last week so I could get the new iLife on it). Seems like this latest OS version is a bit buggy or at least incompatible with a lot of Apple's products in different ways.
Fight On!

UPDATE:
Service was due and now that I saw the machine fail 4 times in a day doing the same process I knew I could duplicate the issue on demand. That's a big bonus.
Called Apple Care yesterday morning and the guy I spoke with read over the notes on my case after I told him what happened the day before (black friday, 4 shutdowns). While he didn't transfer me to a Product Specialist, he did talk to one for quite a while (I was on hold for about 20 minutes while he did this). He said I could ship it to Apple and they would look at it or I could take it to an Apple Store or Authorized Service Center. Thinking this was the next step I had secured a time at the Carlsbad Apple Store for late that afternoon (my usual & closest store, Escondido, was booked all weekend). They told me to take it in and reference the case number. The Product Specialist thought it sounded like a logic board and would duly note that diagnosis in the case history.
After the conversation ended I decided to make sure I could cause the failure. So I started the process (threw out the face.db from the iPhoto Library package and opened iPhoto whereupon iPhoto begins a scan of the images for faces. Having over 12,000 images gives it a lot of work). This time I decided to monitor the workings of the laptop using iStat Pro (freeware widget download & I recommend making a small donation it's so good). I kept track of the processes at 5 minute intervals, the CPU usage, numerous temps AND the fan speed. The latter seemed to be the critical. Shortly after the fan speed got to 4700 the shutdown occurred. It took 36 minutes from the time I started. The fans kind of confirm to me that it could be the logic board.
I took the laptop to the Apple Store and started the process in front of the "Genius." He read through the case as well as the printed copy of this thread and other notes I brought from previous shutdowns including the data I mined from iStat Pro. He was unimpressed and thought it was a non-issue. I guess that's only fair because I was unimpressed with him. He figures it's my system because of a software conflict somewhere. His answer was to do a clean install and reinstall all the software from the original disks. I told him I have spent over 50 hours on this issue to date and that what he was suggesting would take at least that much and guarantee nothing if it's a database issue...duh! Disagreement. Oh, and he also doubted it would fail just from making it work.
43 minutes after starting the process, well after my "Genius" went home for the day (I was his last appointment), the failure occurred. The "Genius" he handed me off to was working with someone else next to where I was sitting. When the fans hit 4700 rpm I told her it was going to happen soon and as I finished my sentence the failure occurred! Cool.
They have the machine and I'll let you know what they do.
Fight On!

Switches off when I unplug power

This last few days I have started experiencing a horrible problem. When I unplug my power supply with battery fully charged (battery less than a year old) the computer loses all power and WILL NOT start up without the power supply.
When I plug it back in it will restart has reset time to 1970, etc.
Why would this happen out of nowhere and how can I resolve it?
All help very much appreciated.
Thanks,
David

Hi David,
It does sound a bit suspicious. Here's a couple of things to try first. Post back if it doesn't change.
Resetting PowerBook and iBook Power Management Unit (PMU)
1. If the computer is on, turn it off.
2. Reset the power manager by simultaneously pressing and then releasing Shift-Control-Option-Power on the keyboard. Do not press the fn (Function) key while using this combination of keystrokes.
3. Wait 5 seconds.
4. Press the Power button to restart the computer.
Resetting PRAM and NVRAM
1. Shut down the computer.
2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
3. Turn on the computer.
4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
6. Release the keys.

Won't boot up unless I unplug power cord first

After shutting down my iMac, if I leave the power cord plugged in like overnight, I cannot boot up. It sounds like the computer is already on because I can hear the fans whirring and hear a click, but I do not get the ping and the screen stays black. But if I shut down the computer and say within 5 minutes try booting up again, there is no problem. I took it into the Apple Store once and they kept it for a week but they said they could not recreate the problem. Is there a problem with unplugging the computer after shut down every time. I am still under warranty until December 2010.

Hi, 2 ideas:- (1) go the SMC & PRAM reset route. (2) Take it to your local Apple Approved Service Agent..

PRAM -> http://support.apple.com/kb/HT1379

MBP temperature when on battery power

Is it normal that my MBP runs so hot when on battery power that I cannot even use it on my lap? It seems like most of the heat is coming from the area below the top 3 rows of keys (if that makes sense) and not the battery itself.

Yes, the case is a heat-sink; Apple call them "notebooks" not "laptops" and warn against having them against your skin.
"Do not leave the bottom of your MacBook Pro in contact with your lap or any surface of your body for extended periods. Prolonged contact with your body could cause discomfort and potentially a burn"
MacBookPro_UsersGuide page 107
Actually, you don't want heat near the battery itself as that's not good for li-ion, that should feel relatively cool?
