You know how when the battery dies the mac restarts in the exact way you left it? well, i was wondering if there was any way that i could put in that mode on my own (without pulling out the battery or hurting the mac).
View 7 RepliesThe battery on my MBP (2007 2.33 Core 2 Duo) has started to die, just like the three others that came before it. It seems like it's only been a year or so since I got a new battery. Yesterday, I was using it unplugged and the computer shut off when the battery was around 58%. I have never seen a battery shut off that early. The worst I had seen before that was a previous battery that would die around 35%.
A couple questions:
1. Is there something I am doing that is causing my batteries to keep dying so quickly? An Apple Genius told me that keeping the computer plugged in all the time can burn out the battery. I don't really want to bother putting the computer through unnecessary charge cycles to keep up the battery life.
2. Is there any way to recoup some of the lost battery life of my current battery, or is it just dead?
3. In replacing the battery, should I buy another Apple battery from the website, or are there better quality 3rd party MBP batteries?
4. On a side bar, I am thinking about purchasing a new MBP, but I am worried that the battery will have the same problem, and it will be much more of a hassle to fix because everything is internal now. I hate having to hand my computer over to Apple Care for a whole day and be without it.
My MacBook is still going strong, but in the event that the battery dies, will it still run on AC power?

What exactly is a battery cycle?

My c2d mbp would just wake right back up and be ready to go.
View 5 Replies View RelatedI have a mid2009 MacBook Pro 15" 2.8 Ghz with an 1TB in the main bay and a Verbatim 128GB SSD in my optibay. I also upgraded my RAM to 2x 4GB. It runs the latest Lion version.
Here is my problem:
When I work on my battery and there's no power left, it automatically shuts down. Right? The sleep/wake light lights until the battery is out of power. If I then try to reboot, the Apple and a loading-bar appear which shows that it is recovering the previous session so that I can continue where I left (right?).
The problem is that it fails at 1/3rd of the bar and the screen goes black. After resetting PRAM and the other resettable things, it still won't boot on that partition.
I tried to repair from an external Lion installation drive, my second partition (which also runs lion) and from the Recovery HD (of both partitions). I always get the same problem (see picture).
This is happening to me all the time. After several reboots i can acces my files again, but I still can't boot from my partition because it fails loading my last session. It certainly isn't the disks fault because I can boot from the other partition on that very same disk w/o any problems. Right now I'm trying to make an identical copy with Disk Utility (as described by Apple).
My question now is: Can I repair the partition by any means without reformating it (as I did the last times)?
Furthermore: Can I just disable the function that tries to backup/restore my last session so that my MBP just shuts down or does a hard shutdown when the battery dies?
PS: My Time Machine drive is at the moment not available, so I couldn't backup in a while, I need the files.
I have a Macbook Pro from 2007 (aluminium keyboard). Everything was working great until a couple of days ago, when I replaced the battery.
No every time I choose to shut down the computer, it will restart and NOT shutdown. I have tried several things - the only thing that seems to work is to unplug the power chord - then it will shut down, but if the power plug is connected, the computer basically can't shut down - it just restarts.
calibrating my battery for the first time this morning. i just opened my macbook pro to see that the time left icon jumps every minute. it goes from 8:50 to 12:38 to 6:54 to 11:37 to 7:40! and now it went from 8:45 to 9:19! the percentage remaining is consistent and correct but the time left is way out of whack! sorry for the slang! now it went from 9:19 to 9:11 then 8:47. i have the screen at the lowest brightness, no backlit keyboard, nothing else running except firefox. i wasnt aware that i was supposed to calibrate my battery and its been about 3 months since i bought this. now its at 8:37 now 8:18. this is quite
View 5 Replies View RelatedMy Macbook Pro keeps shutting down before I reach zero percent battery and often when the battery still has 25% left. I am wondering if this is a software issue that may be fixed or if there is something incompatible with my hardware. I am running 10.6.4 with a 2.16 GHz Intel Core Duo, 2 GB 667 MHz DDR2 SDRAM memory bought in April of 2007. My mac was originally running Tiger, but a few months ago I updated to Snow Leopard.
View 5 Replies View RelatedI have already run the battery down to zero left it over night and started it up and it had 2% so I ran that down again. Is it now suffice to say that it is dead? Or should I leave it for the rest of the day and try to turn it on and run it down once more

Coconut Battery is showing that I only have about half of my original battery max limit left, but now I'm getting a message that says "Service Battery" when I check battery info from the icon on the top of the screen. Anything at all I can do at this point, short of buying a new battery?
View 3 Replies View RelatedA little while later I notice the MBP felt like it was running when I touched it. It was vibrating from the HD running. I didn't think much of this.
I just now tried to turn my MBP on and it wouldn't. I decide to plug it in. When it turned on it did so for about 2 seconds, turned off, then turned back on. It then took a long time to boot up. When it finally did boot, it told me that the clock was all out of whack and I noticed tons of my settings had been reverted to default. I then check the battery to see that it is charging but the level is at 1%! When I shut the MBP lid earlier to put it to sleep the battery was at least 50%.
I have my mbp just 3 weeks old and I tried to calibrate the battery just few hrs ago. I continuously used my mbp until the battery level reached to 2% (the warning message showed when it was 6%). Just then I had to receive a phone call. When I was busy talking, I noticed that the mbp has gone to sleep mode but when I returned (2-3 mins later), I found it shut down. Well, I think it should have remained to sleep mode but it didn't.
Then after an hour I connected the power cord and switched on and noticed a progress bar which I saw for the first time. I have been charging it for 40-50 mins, now. Also the health of my battery keeps fluctuating between 95-100 %. istat shows this. Is this normal? So what I want to know is, Is this normal for mbp to shut down when the battery reach that low? OR there is some problem in my MBP?

So i noticed I had no charge left in my little battery icon on my Macbook Pro so I plugged in my charger. There is a little green light on my charger but it is not charging the macbook pro.

View 6 Replies View RelatedThis is my first post, and I apologize as it's a little long. I just wanted to get the whole story on the table and clarified.I've had one of the new Aluminum 13" MacBooks (2.0GHz C2D) since Christmas Eve. A few weeks ago, it accidentally fell off my desk at work (not a far drop , but far enough for my heart to stop for a few minutes) when I got tripped up in the power cord under the desk.
For all intents and purposes, the MacBok seemed to work fine. I had one of our IT staff, who happened to be a trained Apple repair tech, take a look at it; the only real damage was that the display hinge had been knocked a little out of alignment. Just ot be on the safe side, I took the machine to the Apple Store, where they told me not to worry about attempting to get the hinge fixed (because I'd be paying a lot of money for such minor work), and the Genius sold me a hardcover plastic Speck case for the MacBook.
While the Speck case certainly looked nice and madethe already sturdy laptop feel sturdier and "protected", I was a little concerned about the amount of heat the machine was giving off within the case. On Sunday, I unplugged the machine from the MagSafe charger for a few hours and left it closed in sleep mode. When I woke it back up, the fan on the left continually gave off some sort of high-pitched whine whenever the computer was in idle mode.
I Googled, searching this site and others, and read about the "CPU whine" in the previous generation MacBooks and MacBook Pros. I also saw where a few people with new Aluminum MacBooks were having this same issue or something similar:
URL
It seems to only make the noise when the computer is running off of the battery - plugging in the MagSafe charger makes the noise quiet 85% of the time (I've found that plugging, unplugging, and replugging will not stop the whine from occurring).
I tried installing QuietMBP as was recommended in some posts, but the only setting that will stop the computer from whining is the "highest" setting (that is, allowing the processor 0 seconds of idle time), which causes QuietMBP to eat up 30% of my processor usage in Activity Monitor and to start the fans going (and, presumably, to significantly lower my battery life).
I don't know whether all of this was the result of the MacBook falling, from it overheating in the case, or something that "just happened". I set up an appointment with the Genius bar for today at 4 PM, but Idiscovered another odd occurance when I set up a new account for the Apple Store (rather than give them my password)
The noise never happened under the new account. Never. I left the machine idle until any and all initial processes were done. No noise. I checked Activity Monitor for stray processes. None. And no noise.
Now I'm bewildered. Could something have gone wrong somewhere in my account, leading to a corruption of a power management utility or process? I'm not canceling my appointment, but I am going to try a few things before I leave. I've already repaired disk permissions, and I'm about ot reinstall the 10.5.6 OS X combo update. Should I try to reset the PRAM too? What other options should I be looking at?
Or should I just wait, and let the Genius Bar folks look into it? As a note, I'm aware I may have to pay for any repairs because they may or may not blame them on the MacBook having dropped (despite two to three weeks passing between the fall and this issue arising), and I'm okay with paying for reapirs (though I will try my best to argue my case, of course).
I was working in Illustrator when my screen went mosaic and scrambled, went purple, then black. Restarted the mac in safe mode and had the screen back for a few moments then it froze, scrambled and quit. Since then I have not successful rebooted with the desktop coming up. I think it may be the graphics card, (I hope), because it became quite loud before I shut the computer down. I hope it's neither the ram or the mother board.

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.

My MacBook Pro which is only a year old was working fine, the only small problem was that it wouldn't play a video, so I restarted it but it never came back on. So I restarted it manually, the small light on the edge lit up, the screen with the apple came up along with the load bar, the empty load bar flashes a couple of times then the computer totally shuts off. Have turned starting in safe mode, same thing. Have tried starting holding down apple + option + R + P when turning on, same thing, have started starting up with the install disc in, same thing..

I've got a 2gb MacBook Black, which is about 2.5-3 years old.
Last year (about October I think) I had the hard drive fail, at which point I got the IT guy in work to replace it with a spare from a similar machine. The new drive has just failed - it makes tick-tick noises when you try to boot up, and the ?-folder icon appears on the screen. The new drive is dated 2008, so it's not like it got an old wreck.
Could I have another problem that's killing hard drives? The only non-standard thing in the machine is a memory upgrade from [URL]. Are there any common user behaviours which would increase the risk of hard drive failures. The machine is left at home most days, and is always carried around in a padded sleeve/case.
The machine mostly gets used for internet browsing, with a bit of iTunes and photo organising, but nothing particularly heavy.
It's a Hitachi hard drive that was in it - I've ordered a Seagate as a replacement. If it dies I'll get a new machine, but I'm hoping I won't have to.
I posted something up a little while ago.. Just got this Refurb MBP 15.4" 2.66Ghz 320GB HD 9600 512MB And when my computer dies (0%) it doesn't go into regular sleep, so when I plug it back in I can't just hit the spacebar. I don't like this and want to be able to turn this off?
View 7 Replies View RelatedThis only happens occasionally, but sometimes when I have my speakers plugged into my 2010 macbook pro, the sound just dies. If I unplug the speakers the sound comes through the built in speakers, but the only way for me to get the jack to work again is by restarting my computer.
Has anyone else experienced this? Is it a hardware or a software issue?
I bought the 15" Alum Pro model before they came out with the newer Unibody. Up until now it's been the best thing that ever happened to me. My problem is about 3-4 times during the workday the keyboard and trackpad both freeze causing me to manually power down. After it happened about 5 times, I decided to spend two hours on the phone with Applecare.Long story short...they had me check the ram and do a diagnostics on the hard drive ( I guess the equivalent to disk defrag?) Taking the battery out and going through a bunch of processes that all came back fine and after all that the problem persists.
View 8 Replies View RelatedI have been trying to correct an issue with my E-mac 1.25 Mhz., 1Gb ram and finally broke down and decided that the way to go was to reinstall the system.
All went fine and 10.3.4 now resides on my drive. I had previously downloaded and reinstalled the 10.3.9 Combo Updater. Now, when I double click on the dmg the Installer starts and dies.
MBP not booting up? I press the on button and the screen flashes for a moment and then it dies again... once I actually got it to some screen that said HD and Restore but when I clicked on HD it died immediately again...

This is a bit of an odd one.
My GF dropped her MacBook the other night, and since then Leopard would only be able to start in safe mode, and then be very slow accessing the hard drive. I figured the drive had died, but I decided to test it on other computer and it works fine.
Anyway, I did a fresh install of Leopard, which went fine and boots up, but any subsequent boot it dies. Booting in verbose mode, it comes up with some errors on the efiboot screen (I can't remember exactly what they were). I still have access to all the usual boot options etc.
So on a whim, I boot camped up the disk and installed Windows 7 to see what would happen. It installed fine, and works 100%. No complaints about anything at all (except there being Windows on there :P), all hardware functional!
Does anyone have any ideas what the problem Leopard (10.5 and 10.6) might be having? I've erased the drive several times, both quick and zeroed, repaired it and so on.
what is the exact hardware of the mac pro?
