Mac Book Crashing in while on battery

I have a 17 inch macbook pro - it is fully patched/updated and I have gone through and tossed cache files, finder prefs, reset vram/pram, rebuilt permissions and checked harddrive integrity. The only things I have not done is reset the pmu, which I am going to do after I send this. When I untether from the cord, I expereince hard lockups that do not even record anything in the crash logs (that I have ever noticed) I assume that this is a kernal panic severe enought to totally block any futher program logic. I can work for hours with the computer plugged in. I did let the computer run asleep on the battery for 2 days and it woke right up, though in a somewhat discharged state, it did lock up serveral times while recharging. I suspect that the battery is flaky on this unit - is there anything further that I can test/check or attempt to resolve?

I once experience this issue with my old Powerbook when I upgraded the RAM. I got some cheap RAM for free and stuck it in and it worked, until I unplugged power and I got a kernal panic.
Basically what happened to my Powerbook (and I'm assuming this is the same issue - that is if you upgraded your RAM recently) was in the energy perferences you can select what processor performance to use based on what the power supply was - high performance on power adapter and low performance on battery power for example; this is called processor slewing. Basically some kind of inferior RAM cannot handle it when the processor instantly changes speed.
I spend the money and got some nice Samsung RAM and the problem went away. Not sure if this applies to the Intel mac's though...

    Go to System Preferences>Displays and set the resolution to "Best for this computer" (or something to that effect).

  • My Mac book pro froze while streaming Netflix?

    Mac book pro froze while watching Netflix?

    How large is your hard drive and how much hard drive space do you have left?
    Please describe in detail all you have attempted to do in order to resolve the issue.
    It is very difficult to offer troubleshooting suggestions when the "os version" you are using is unknown as each os has their own troubleshooting solutions.

  • Why is my Mac Book Pro not charging the battery?

    I let my Mac Book get down to 4% and now its just taking power to stay up. When will it charge my battery?

    Keep it charging for a while.
    If you can, do not use the computer for a while.
    Let it charge.
    Best.

  • Mac book crashes after Itunes upgrade

    My Mac book will not boot now after upgrading to I-tunes 8. Has anyone else experienced this? What have you done to fix?

    absolutely! It happened to me when I updated Firefox, and I was able to correct it. Try holding CommandOption+PR all at the same time while booting up. The "ding" sound when you boot up will repeat while holding the buttons. I believe you want to hear the "ding" sound 3 times then release all 4 keys. This resets something known as "PRAM" which fixed it for me the first time. Since then, I updated to Itunes 8 and Quicktime 7 and now my laptop will not boot at all. I tried resetting the "PRAM" again and got nowhere. Let me know if you solved your issue.

    Can anyone tell me what this means and how I might be able to fix the crashing problem. I do use this computer A LOT for at least 6 hours a day and because I study moving from class to class I have to put it to sleep would this be the cause because of frequently put to sleep and frequent use of the computer. I am up to my 3rd SSD (the others have died), my 3rd set of ram modules and I have had the sleep censer replace at least 3 times I have replaced the dvd drive as that died and many of the internal connecter have been replaced (none of these components were damaged from being droped or anything when i got it fixed i was told that it just 'died' and i could not do any thing to avoid it. Can some one please help me because I have tried many fixes software wise and have got nowhere. do i need to get a new laptop or can it be fixed,

    forgot to say, if i get Corsair DDR3 8GB (2x 4GB) PC-10600 that sould work with the laptop?

  • Mac Book crashed

    Okay - I think my mac book has finally crashed.
    It's sorta gone haywire. The dock has disapeared, Finder is not showing all the applications, spotlight is not working, it keeps coming up with an error saying that the spell check is not activated when I type, when select apple, then Mac OS X software a message comes up saying
    'your system settings are being updated. Unable to open preferred web browser. Try again in a few minutes.'
    It also will not shut down or restart, not even with Force Quit. I have to force the shut down by pressing down the on button continually. It has been stuck like this for about 6 hours.
    Any suggestions?
    Thanks

    HI and Welcome to Apple Discussions...
    Have you tried booting from your install disk and verifying the hard disk for errors?
    Insert the installer disk and Restart, holding down the "C" key until grey Apple appears.
    Go to Installer menu (Panther and earlier) or Utilities menu (Tiger and later) and launch Disk Utility.
    Select your HDD (manufacturer ID) in the left panel.
    Select First Aid in the Main panel.
    (Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)
    Click Repair Disk on the bottom right.
    If DU reports disk does not need repairs quit DU and restart.
    If DU reports errors Repair again and again until DU reports disk is repaired.
    When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.
    Select your start up disk and click Restart
    If you cannot boot from your install disk, try booting in Safe Mode

  • My mac is crashing constantly while using firefox, doesn't happen while using Safari

    just wanted to let you know - i've never had any trouble with firefox or my mac book pro (osx) before. i think something is wrong with firefox.

    I have the same problem in Windows 8 with newest, fresh and clear installed Firefox build. It's also for pages like facebook and so on, many pages you visited before. It's a problem with the cache. If you delete them, all is working fine for a short while.
    The problem is thats this will happen nearly every day again, so its realy annoying.
    In my constellations, its an Samsung Ultrabook with SSD drive and Windows Standby is used so, could it be that the cache ore firefox could get damaged while using powersaving mode if you simple open/close the Ultrabook?
    I used Firefox/Windows 8 on my desktop without any problems but i will build in my new ssd tomorrow, so we will see if i get also problems like that by using energysaving modes (its only a speculation, it could also be another Bug in Firefox).

  • Mac Book crashing for no apperent reason

    I had a problem where my macbook crashed for no reason, when I was just doing regular stuff like searching the web. I turned it on again after the crash and it started up but then crashed again within 10 seconds. I waited a bit and tried again but it crashed instantlly, After a few times of waiting then trying it finally started up. It could not be of overheating because I am in a cold place where it is snowing outside and I had barley used the laptop when it crashed. Also it could not be a power surge for I hjave everything connected through a surge box. I was lucky that nothing important was running so i did not lose data but am still curious on what may have happened.
    Does anyone have an idea of maybe why this happened?
    Mac book   Mac OS X (10.4.8)  

    Ive been having the same problem. In OS X sometimes right after I turn it on it will have a kernel panic, other times programs will open for about a second and then immediately close. Its getting very frustrating.

  • Mac Book Crash During Partition

    I recently went to install Windows XP on my MAC, and during the Partition portion of Boot Camp my MAC Book Pro crashed. Once back up, I see that the partition size I had set is no longer visible to the MAC Software, and when I run boot camp again it asks me to partition again. Any suggests on how to complete the install or how to get that partition accessible through OSX. I am currently running the most recent version of Leopard.
    Thanks

    I suspect it is a 10.5.2 issue, rather than a Bootcamp-specific one. Here's why I think that FWIW...
    Earlier this evening I was trying to shrink an existing partition on an external Firewire 800 disk, so I could make room for a new just-for-Time-Machine partition (equivalent to what you'all are doing to make room for a Windows partition on your Macs). I get a repeatable kernel panic as follows. Is the "hfs_lock: locking against myself!" error message the same as you are getting when partitioning for Bootcamp with 10.5.2?

  • My mac book fell asleep while migrating...now it is stuck.  What am i supposed to do?

    I was migrating information from my mac book pro to my new mini mac, and the power cord got pulled and my mac book went to sleep.  It is stuck (after 5 and half hours) and i am afraid of shutting either off.  What should i do?

    Welcome to Apple Support Communities
    If you are transferring your files through Ethernet, FireWire or Thunderbolt, unplug the cable and plug it again.
    If it doesn't work, you will have to turn off both Macs by holding the Power button and start the transfer again.
    Before starting the migration, open System Preferences > Energy Saver, and set "Computer sleep" to "Never", so your migration won't get interrupted because one of the computers went to sleep.
    Also, consider reading Pondini's articles about transferring files through Setup Assistant and Migration Assistant > http://pondini.org/OSX/Setup.html

  • Mac Book Pro Shuts down on Battery Power

    First, I apologize to everyone for asking this question yet again. I have gone through the previous posts and I am still at a loss. So thank you for your patience and help.
    When I run my MacBook pro on battery power it will run for around 15 - 20 minutes... then just be dead. No low battery warning. No shut down. Just poof and gone.
    I have looked at my power settings to see if my battery is bad. But I don't have a Status indicator in there. I see This:
    System Power Settings:
    AC Power:
    System Sleep Timer (Minutes): 0
    Disk Sleep Timer (Minutes): 10
    Display Sleep Timer (Minutes): 0
    Automatic Restart On Power Loss: No
    Wake On AC Change: No
    Wake On Clamshell Open: Yes
    Wake On LAN: Yes
    Display Sleep Uses Dim: Yes
    Battery Power:
    System Sleep Timer (Minutes): 0
    Disk Sleep Timer (Minutes): 10
    Display Sleep Timer (Minutes): 0
    Wake On AC Change: No
    Wake On Clamshell Open: Yes
    Display Sleep Uses Dim: Yes
    Reduce Brightness: Yes
    Battery Information:
    Battery Installed: Yes
    First low level warning: No
    Full Charge Capacity (mAh): 1185
    Remaining Capacity (mAh): 1185
    Amperage (mA): 0
    Voltage (mV): 12426
    Cycle Count: 174
    AC Charger Information:
    Connected: Yes
    Charging: No
    Hardware Configuration:
    UPS Installed: No
    I have also looked at the directions on http://support.apple.com/kb/ht1490 about how to calibrate my battery. It says:
    " 1. Plug in the power adapter and fully charge your PowerBook's battery until the light ring or LED on the power adapter plug changes to green and the onscreen meter in the menu bar indicates that the battery is fully charged.
    2. Allow the battery to rest in the fully charged state for at least two hours. You may use your computer during this time as long as the adapter is plugged in.
    3. Disconnect the power adapter while the computer still on and start running the computer off battery power. You may use your computer during this time. When your battery gets low, the low battery warning dialog appears on the screen.
    4. At this point, save your work. Continue to use your computer; when the battery gets very low, the computer will automatically go to sleep.
    5. Turn off the computer or allow it to sleep for five hours or more.
    6. Connect the power adapter and leave it connected until the battery is fully charged again."
    Only I have a problem withe step 3 and 4. I don't get the warning, and it doesn't go to sleep. So, I don't think any calibration is working.
    Do I need a new battery? Should I just buy one? This computer is WAY out of warranty and I never purchased and apple care plan for it.
    Again, than you for any and all advice on what I may need to do.

    I think it's time to buy a new battery

  • MAc book crashing after Mountain Lion download

    My MacBook Pro crashes when I move icons on my desktop. after it loads  I get error message  with a bunch of nonsense and GPU Panic which applecare peeps seem to think is a problem with graphics? I downloaded Mountain Lion yesterday. Help! it keeps crashing. I am panicking!

    You have the MacBookPro6,2, the Edsel of Macs. It has a defective logic board that may be covered by this recall program:
    MacBook Pro (15-inch, Mid 2010): Intermittent black screen or loss of video
    Make a "Genius" appointment at an Apple Store, or go to another authorized service provider, to have the machine tested. The routine hardware diagnostics used by service providers do not detect the fault. There is a specific test for this issue.
    Print the first page of the panic report, and the support page linked above, and bring them with you.
    Note that the recall only applies within three years of purchase. After that, Apple may refuse the service. In that case, you may be quoted a price of about $300 (in the U.S.) for a "depot repair," which involves shipping the unit to a central repair facility and takes about two weeks. For that flat fee, anything found wrong with it should be fixed, not just the logic board.
    The model was discontinued in February 2011, so the replacement program will be ending soon. Some units may have been sold by Apple as refurbished after that date.
    Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.
    Sometimes the replacement part is also defective, so be prepared for that possibility.
    If it's too late for your unit to be repaired under the program, and you don't want to pay for a new logic board, you may be able to stop the panics by disabling automatic graphics switching.
    *An SSD doesn't need to be zeroed.
