MacBook Pro :: Battery Dies Around 50 Percent?
Oct 10, 2010The 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.
MacBook Pro :: I7 Taking Forever To Wake Up When Battery Dies - C2d Didnt?
Jul 26, 2010So when my mbp shuts off after the batter dies and I plug it in and press the power button it takes awhile for the screen to come back on, and then for the little white bar at the bottom, and then when everything is back, I cant use any apps for a minute or two because they won't open. My c2d mbp would just wake right back up and be ready to go.
View 5 Replies View RelatedMacBook Pro :: Partition On SSD Broken After Falling Into Sleep When Battery Dies?
Apr 4, 2012I 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:Â
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).Â
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). Â
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? Â
PS: My Time Machine drive is at the moment not available, so I couldn't backup in a while, I need the files.

View 7 Replies View RelatedOS X :: White Macbook Runs On AC Power (no Battery) But Not On Battery?
Apr 29, 2010Just wondering if anyone has ever encountered this or if any experts out there know of the issue.I have a spare White Macbook (late 2008: Core 2 Duo 2.1GHz, 1GB, 120GB) that I'd like to set up for my brother to use to introduce him to the wonderful world of Macs. The problem it is having is that when I have a battery connected to it (I tried 2 different ones included a known-good one that is brand-new just purchased from Apple) it powers on and gives me the chime, but then immediately shuts off unexpectedly giving that little "whine" sound like if it just lost power all of a sudden. However, when i take out the battery, and just plug it into the Magsafe AC charger it works fine. Also when just trying to run on battery it does not turn on at all. Here's some cliffs:
1) Macbook with just battery does not turn on
2) Macbook with battery + Magsafe AC charger connects powers on, gives the chime, but then immediately shuts off making the "whine" sound as if the power was suddenly cut off
3) Macbook with no battery connected and just the Magsafe AC charger connected works fine.Do you guys think this is either:
A) battery connector issue (the little piece with the metal wires that the battery connects to. ~$50 part)
B) Logic Board issue
I already tried resetting the PRAM and SMU to no avail.
MacBook Pro :: Battery Running On Reserve Battery Power
Jun 18, 2010I just turned on my 13" MBP and got this message. Apparently, this is supposed to come up when there is only like 5% charge left. My battery indicator at the top of the screen said there was 22% charge left. Also, according to IStat, my battery's health has already dropped down to 97% after only about 2 weeks and 5 cycles. Is this normal? I'm going to try recallibrating my battery by fully charging it and then letting it fully drain. Is there a good chance that this solves this problem?
View 1 Replies View RelatedMacBook Air :: "Proper" Battery Usage For New - Aka Power Supply Vs Battery?
Nov 29, 2010As I just bought a 13" MBA, I am still in my "babying" phase of the machine and want its battery power/capacity to last as long as possible. I have already done the battery calibration recommended by Apple (not even sure if its 'necessary' but I did it anyways), with charging, resting, draining, resting, and re-charging. But now I am worried about the battery cycles. Should I only plug my MBA in when the battery is close to being drained (aka use it on battery power for most of my usage?) or is it okay to drain the battery to like 80% remaining, charge, and then drain to 70% remaining, then charge again? Im not sure if Im making sense, but basically I don't want to be wasting these valuable cycles, as they seem to determine battery health and longevity. So what is the proper battery usage for the MBA, or is it basically use off power when you want and use on power supply when its available?

PowerPC :: Powerbook G4 Won't Power Up - Battery Indicator Showed One Flickering Power Circle?
Mar 19, 2008My girlfriend has a 12 inch Powerbook G4. She noticed that the battery life was starting to dwindle. Tonight, she tried using it. It wouldn't power up. The battery indicator showed one flickering power circle. The adaptor has the green circle on it, indicating the battery has a full charge. However, the computer won't charge up.I've read the 12 inchers don't have separate PMUs. Could that prevent the machine from starting? She was using it earlier this evening, as she e-mailed me pictures from our vacation.

MacBook Pro :: 10 Min To Power Up When Battery Is Down?
Jul 29, 2010I have a mid-2007 MBP. Here is my issue...it's been more than a year that when I totally discharge my battery (meaning the MBP shuts down), when I connect it back to the charge it is taking abotu 10 minutes to power up again...it was not the case before and my wife's MB is working well....meaning when it is down, just connecting the charger the MB is back on within a sec.
I have changed my battery but it did not change anything, I called Apple and they recommended me to restore snow leopard...which I did...I still have the same issue.
Does anyone experience this? Any idea what is happening (HW or SW issue) and is there a potential fix?
Battery Won't Power MacBook
Jun 21, 2012I have just bought a second hand MacBook laptop and it has a wierd battery issue that can't seem to find mentioned anywhere.Initally all seemed fine, but then I noticed the battery wasn't charging and the battery menu reported no battery found, also the MagSafe plug had not light; some searching instructed me to reset the SMC which I did, and everything was fixed, I could runs the computer from the battery and the power lead charged the battery. But now (just a day later) the battery won't power the computer at all - the computer will only work if the power is connected - however the light is shown on the MagSafe plug and the battery is being changed, but if I disconnected the power lead, first I see the restar/sleep/shut down dialog that you see when pressing the power button, then shortly after the computer turns off, if the power if reconnected, it boots from scratch, so it wasn't asleep!

View 1 Replies View RelatedMacBook Pro :: I7 Processor Will Not Power Up After Battery Ran Out
May 21, 2012The 2011 macbook pro with i7 processor will not power up or charge at all. The problem started after my battery ran out and the computer shut down. Since then, when I plug in the charger only the green light turns on. In addition the light on the base (in front of the keyboard) flashes. Nothing happens when I hit the power button. The charger still works on other laptops. To emphasize, the screen will not even light up. It sounds as if the computer is starting (for less than a second) before stopping, only to start again but that is purely speculative.

MacBook Pro :: Turns On But Then Dies Before It Starts Up
Mar 19, 2012My 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..

MacBook Pro :: Battery Calibration - Power Cord
Oct 12, 2010Well I just scored a 15 inch 2.4 from Bestbuy for 10% off. SOmebody just returned it having never even used it, but they had to discount it because it was opened. I love it love this thing!We did migration from our imac and everything came over. AmazingOne question about calibration. I charged it fully and let the power cord be in it for an extra 2 or so hours. I then used it unplugged until it basically shut off due to no power. Cant I just plug it in and let it charge all the way without letting it sit for 5 hours. Its not sleeping I dont think. It actually shut off suddenly as it was at zero percent. There is no power to it at all that I can tell. Will charging it now without leaving it unplugged for 5 hours ruin the calibration??

Dec 2, 2010I have a late 2007 MBP 15inch 2.33Ghz Core 2 Duo. I have had since new and no problems. Over this last week I have had the same issue a couple of times. The MBP just switches itself off. The first time it did it, it was running on battery (I was using Aperture) and had 60% power available. It would refuse to re-start until I connected it to the mains and then it ran fine.
Then it did the same thing overnight at some point. I had left it connected to the mains (as I always do at home), had shut the lid to put it into sleep mode. When I came back it was switched off. No-one had touched it whilst I was away but yet it had just turned itself off.The only thing that I noticed was that when I started it up both times the little light on the magsafe connecter kept flashing between orange and green. However when the computer booted into OS X both times it showed a reasonable amount of power in the battery.

Jun 21, 2010I'm just wondering if anybody knows whether it is possible to obtain a replacement battery and power supply for such an old computer. My 17-inch MacBook Pro is about five years old, and the battery seems to be completely dead. It will not start up, will not take a charge, and cannot be used, whether plugged in or not. A multitester test suggests that the power supply no longer works either. My MacBook has one of the older-design power supplies, with the circular port, rather than the newer, magnetic, rectangular ones. I'm planning on getting a new MacBook in the near future, but I need to access some things that are saved on my old Mac's hard drive, if at all possible.

That seemed very weired, I was sure it was at 98% last night. I decided to switch my computer off and let it charge all the way up.
When I turnt on my computer again i checked the battery and everything seemed normal, but after half an hour or so I noticed that my battery status icon had chaged from charged to not charging. I loaded up Coconut battery and the battery was slightly over 90%...and it's still draining out while tipyng... The AC socket is fine and I have an HDTV connected to the same power source. Needless to say the tv is working normally... I do not have an Apple shop nearby, the closest is over 200 km (approximately 140 miles) away.
