i have an older C2D MBP on its second battery. I don't normally use it on battery power so my cycle count is pretty low. I have attached images. It is telling me to service my battery. Should i be getting a new one? if so, how are the NuPower batteries @ OWC?
View 2 RepliesThe title says it all. I have a new battery in my 2007 MacBook, but my computer still says it's at 237 cycles. Is there a way to reset the cycle count? It does say, however, the battery is at 100% health.
View 3 Replies View RelatedWell I've had my mbp(new model) for just a month now and the cycle count is up to 60 and battery health has gone down to 96%. Should I be worried or is it normal?
View 10 Replies View RelatedSo first off, I absolutely love my MBA. Now that we have that out of the way. Since day 1 I've noticed that the cycle count on the battery seems to be climbing MUCH faster than it should.
- I've had the machine 51 days. I was out of the country without it for 9 days so really, I've had it for 42 days.
- According to iStat and System Profiler my battery's cycle count is 37
- According to System Profiler my battery's health is "Good"
- According to iStat my battery's health is at 98% (It started around 96%, has been as low as 94% but seems to have settled in at 97 or 98% for some time now)
- According to system profiler my maximum charge is 5006 mAh. (It's also gone up a bit since the machine was new).
I thought the definition of a cycle was the equivalent of 100% depletion of the battery -- whether that's one long unplugged stint that sucks it dry or 10 really short ones. A cycle is the same as using ~5000 mAh of battery power. I've been really good about keeping it plugged in while I work (the outlet is conveniently located). I've run the battery most the way down maybe 5 times. I do, however, run it down 10 or 20% almost every day as the machine travels with me in sleep mode or spends the night unplugged in sleep mode at my girlfriend's place).
I haven't done any careful testing but it seems though that if I run the battery down just 20% or 30% or so and then charge it all the way back up the cycle count increases by 1. Considering I've only used it for 42 days, and the cycle count is already at 37, I'm worried that it will hit 200 cycles by the time it's 8 or 10 months old. Isn't the point where battery performance starts to wane? Anyone else out there notice a rapidly climbing cycle count?
I got rained on and my macbook got soaked. I dried out my macbook in an airtight container with some special salt for a few days, and luckily got rid of most of the water issues with my monitor. Unfortunately, my battery or logic board seems to have not been so lucky. My macbook is a one and a half year old 13" unibody, and now won't turn/stay powered on unless it's plugged in. For the first 15 minutes I've plugged in the magsafe charger, the battery is recognized. It says it's charging but stays at 0% (I then get the X over the battery icon). The weird thing is that my previously health battery now has a 0 mAh charge capacity and a 0 cycle count. Is there ANY possible solution to this, or has the damage already been done?
View 3 Replies View RelatedIs it true that when we charged 100% battery and it says on AC power, does it LITERALLY do what it say? i mean the power of Macbook pro is not provided by battery but by magsafe instead. is it?last thing, leaving the Macbook connected to the working magsafe isn't add numbers up to cycle count right? and is it okay to charge the Macbook pro all the time and only using it when we could't find AC power outlet?

My girlfriend's 06 or 07 white macbook is starting to stop charging pretty often. Sometimes toying with the plug or turning it around fixes it, but then it will stop again. She tried it with my roommates plug which seemed to work fine.
View 8 Replies View Relatedi have a 13" mbp with 130 cycles an i use it extensively.its been about 6 months since i bought it and i noticed tht apple will cover my battery in warranty fr one year only if it has less than 300 cycles on it.
my problem is tht i typically use my laptop fr no longer than 4 hours at a time. which means i recharge the battery jus before the battery meter hits red an counts 1 cycle as complete.thts why i got less number of cycles on the battery
cn i continue doing this without any adverse effects to my battery and its life ??
I just got my battery replaced and after a full charge both istat and mac osx shows that there is only one cycle available. I remember that my previous battery used to have at least 60 cycles. Is 1 cycle normal for new batteries or?
View 3 Replies View RelatedI have searched countless threads about battery health but I feel that each individuals battery health situation is so unique due to the numerous fluctuations.
I have a 2010 13" MBP with battery health of 92%. Load cycle: 13. and Age of 4 months( but i got it 2 months ago)
Should I be concerned with the battery health at this point?
I noticed that my battery cycle (according to istat) switches over at 15%. So as son as it switches over to the next cycle I plug in the adapter to make the battery run a cycle from 100%-0.(I know the cycle in 100%) But it still switches over at 15%, that means that the battery ran only 85% of its capacity. How can that be? Is it possible to reset (delete) battery cycle data?
View 2 Replies View RelatedI bought a MacBook Pro 3 months ago, despite in the first charge I follow the instructions of the store. The problem is that my battery doesn´t complete the cycle of charge, if I disconnect my computer and the value of the battery decrease at 95% 96% 97% 98% or 99% and I plug again the charger to the MacBook Pro, the battery doesn´t charge at 100%. I followed all the instructions of synchronization but the battery remains the same.

I had some issues with battery drain while sleeping awhile ago but that problem has been solved. However, ever since that incident I could not be paranoid about the battery life etc.I heard people saying that leaving the charger plugged in is simply fine as long as I do the regular calibration once or twice a month or so. Yet, Apple stated that they do not recommend the laptops to be plugged in. I will be going to a college this Sept and I really do want my laptop to last at least the whole 4 years.
Ever since I have contacted Apple customer service about this Battery issue I have left my Macbook charged up and plugged in while using and letting it sleep. One thing I have noticed is that the battery indicator says 99% and doesn't increase or decrease yet the green light is on. Is that normal? Since this is my first Mac ever and also first Laptop I would like some advice on how to treat the Battery( I know how to do Calibration and such). Is it better to do full cycle usage of Alum Macbook battery than leaving it plugged in all the time? (I unplug it when the Macbook is off).
I have my Macbook late-2006 and suddenly the battery do not charge at cycle 103. I tried to talk to guys at Apple Store but the only thing they can do is to sell me a new battery. In fact, the battery was in recall before 2009 but I was not be able to send it back at that time. If the battery die only at cycle 103, is this normal?

13-inch, Aluminum, Late 2008 battery wasn't holding a charge based on the fact that its been used and abused since 2008. Around the same time (2 months ago) my MagSafe power supply started becoming frayed and damaged. So, I decided to buy both a new power supply and battery. I bought the power supply from Apple.com and the battery from Best Buy. Ever since my new purchase I no longer get a count down on my remaining battery level. It either says (charged) or (Not Charging) based on if I have the power supply plugged in. If I leave the power supply out and the battery dies it no longer goes into the power save mode. Now it just turns my laptop off. I have tried a couple things like SMC reset but no luck. Any suggestions? Maybe I am doing the SMC reset wrong? I unplug the MacBook and take the battery out and hold down the power button for 5 seconds. I cant tell that its done anything. Another problem that started happen more recently.. When i close the lid of my MacBook it seems that its no longer going to sleep. The fan is running high and the battery dies..Â

What exactly is a battery cycle?

View 1 Replies View RelatedI purchased a new MacBook Pro 17" with OS X Lion (10.7.2) preinstalled back in January of this year (2012). I migrated my user accounts from my old MacBook Pro 15" (2008) running OS X Snow Leopard. Almost right away I started having issues of all sorts, including Admin accounts that wouldn't allow me admin priveledges, hidden user groups, apps that wouldn't run, multiple obscure error messages and a host of other issues. After scouring forums like this one I used Disk Utility and not only discovered innumerable permission errors but also disk errors like these:Â
Invalid volume file count
(It should be 1656658 instead of 1656636)
Invalid volume directory count
(It should be 345764 instead of 345743)
Invalid volume free block count
[code]....
And now, this morning, after a month or two of all that... and after installing the Java Security Upgrade last night, I can't get into my accounts at all. On first boot-up it hung for 20 minutes before I shut it down. After running Disk Utility from Recovery Drive and repairing the drive I rebooted and got the log-in screen. I clicked on my user icon, typed the correct password, was shown they white/grey screen for a few flickering seconds then was brought back to the log-in screen. I rebooted to the Recovery Disk, ran Disk Utility, saw all the same errors again, repaired the disk, rebooted and got the same problems with logging in again.Â
I've repeated this cycle five times today, as both a normal boot-up and in "Safe Mode" all with the same results. I've repaired the disk using Disk Utility from Recovery Disk as well as accessing the disk in Target Mode, and always there are the same errors needing to be repaired.Â
I don't buy that I'm dealing with a hardware issue. My antivirus and security software are all up-to-date. What the heck is going on? Why do I keep having these disk problems? Why can't I access my accounts anymore? Why does it keep hanging during boot-up? Why am I about to throw the machine out my bedroom window?

My wife's macbook pro started shutting down by itself randomly, so i performed Disk Utility Verify Disk and found these errors: Invalid volume file count(It should be 800651 instead of 800653)Invalid volume directory count(It should be 191005 instead of 191003)The volume Macintosh HD needs to be repaired. Error: Filesystem verify or repair failed. As i do not have the Mac OS Leopard disks physically with me, I target-disk started her mac on my mac, and use my mac to run Disk Utility on her hard-disk, and repaired the disk without problems.Â
However, this is the 3rd or 4th time this has happened. After the 1st time, i figured something is causing it, so i checked this forum, and found that for some, the Blackberry Messenger app causes programs, so i promptly uninstalled it fully (including associated system files) and this problem didnt come back for a while. Or could this be a sign the hard disk is physically failing soon? It is out of warranty now. We have regular Time-machine backups. We are actually kinda waiting out until the new line of macbook pro's come out..

I have a 15" Mac Book Pro that I bought in May of 2011. Especially, when I watch movies or use Skype it gets hot. It's not hot like it can burn me or anything. And I realize they "work" harder when using Skype or watching vids but I was wondering if the computer getting warmer is normal ?

I am so upset right now, this is my 2nd macbook with this problem. I just got this macbook yesterday and the hard drive is making a clicking noise, but it isn't a click....click...click... like a lot of people have had, it's actually more of a quick series of clicks every few seconds, almost like the hard drive is shaking. It goes away for a bit when I am typing, like right now, but after I stop it comes right back.
Also the fan is pretty loud, considering I haven't put anything on the computer yet.. I've already been to the genius bar and all they did was give me a new, worse macbook, so there is no way I'm going back. Are there any fixes for a noisy hard drive aside from voiding my warranty and putting my own in? If it is normal, I might just invest in a good pair on noise cancelling head phones... Thanks!
My Magsafe adaptor is so hot right now that it almost burns me to hold it. It also smells pretty warm, like a heater. This can't be normal can it?
Should I be alarmed? My 13.3" UMBP is only 3 months old...
I will be getting a MBP but I will need more storage, hence the external hard drive. I wanted to buy time capsule but I read that it is not possible to partition it. So, would I be better off with an external hard drive(FireWire 800) that I can actually partition or get time capsule which offers the wireless connection. As for the speed I guess the wireless connection with time capsule must be pretty slow?

Can you fit pretty much any graphics card into a mac pro? (Im new to mac so sorry if thats basic) Also say the card only worked with windows, if I plugged in a card and booted to windows would the card run that way? Reason I ask is that some of the work I do requires running high end games but I hate vista and have always wanted a mac. Im fine with dual booting if I have to but I was hoping that high end graphics cards would work on the mac pro so I dont have to buy two machines.
