Is 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?
The 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.
Well 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?
So 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 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?

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?
I know that it is an old single processor, first of the Power Macs, legacy machine and OS. I have gone through all various check system/disk evolutions with Apple and TechTool Utilities.Also, when I have a software glitch, I can never get the Send To Apple report to "send". I get a message that reads something along the line of 'not being able to connect to Apple'. Why, the legacy problem again? If so, I am suprized that I get iTunes and Safari updates.

I picked up an 802.11n Airport Express card for my Mac Pro last week. The installation went fine, but my Netgear router was only 802.11g. So I felt the need to get an Airport Express now that it?s been updated to ?n?. First I plugged the AE into my switch along with my networked printer, cable modem, and Tivo. My 1st gen MacBook showed me full bars and was very happy. My Mac Pro only showed 2 bars. They are side-by-side and about 20 feet from the AE. Strange. I plugged the AE into an extension cord and moved it closer to the Mac Pro. Still, after the AE completes its POST, I get full bars on the Mac Pro. As soon as I hop on the internet, it drops to 2 bars. It?s really weak and pages take forever to load. Sometimes not at all. The MacBook is still fine.
My wife being used to PC nightmares at work suggested that I reboot. ?Heresy?, I said. ?I shouldn?t have to do that. It should ?just work?.? From the Mac Pro, I turned Airport off and then on again. Full bars again. As soon as I hop on the internet, it drops. So what?s up? Much to my lament, I rebooted. Bingo! It works. Full bars, all the time. So I moved the AE back to where I initially had it. (About 5 feet away next to the cable modem and switch. One less extension cord to deal with.) The AE completed its POST, gave me a green LED and I went back to the Mac Pro. 2 bars again! ERRRR!.............
my name is David Francis and I publish a community magazine in Bowling Green KY. I consider myself fairly adept with computers and technology having been working with them since 1987. I was a full time web developer for 10 years prior to starting a magazine company in 2007. My experience (was) Microsoft (can I say that here?) and PC. I developed ASP websites using SQL databases and I was more or less a MS Partner having invested many years on the PC and the MS Software (lots of money too I should say.) I was "persuaded" to learn the Macintosh by a fellow publisher and friend who loaned me a computer and Adobe software for six months. I must say I reluctant, but realized quickly that I needed the tools and performance of the MAC.
I purchased a brand new MAC Pro in Nov 07 (2 x 2.66GHz Dual Core), this was the same month that Leopard came out and it was included with the new machine. It came with 2gb of ram which I upgrade (MAC certified ram) to 4bg about six months ago.)I immediately installed Adobe Creative Suite CS3 which I purchased as well as Office for MAC, Parallels so I could run Windows (sorry), and a logitech mouse and keyboard............................
I 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:
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.
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.
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.
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 bought a new higher spec (MD322X/A) MBP three months ago (yeah, so I'm a newbie from Windows and didn't know how close WWDC was) that has 1GB of video memory. The About This Mac window reports 512MB of memory. I called JB where I bought it and the guy said this is fine and it will report 1GB in system properties, which it does appear to but I'm not yet convinced that all is well. So, apart from paying 3 months ago what I could have bought a retina display for today, is it normal to report 512MB in the About This Mac window if I have 1GB? Also, after the spontaneous purchase of the MBP because JB didn't have a new iPad in stock, they don't appear to be that much cheaper than other retailers anyway?
I bought an i5 15" MBP last week and instantly through my 80GB SSD into it. I've been doing my best to keep a lot of unnecessary data off the SSD but I'm still running out of space. I'm thinking about throwing the stock 5400rpm 320GB drive into an Optibay tray and using that to hold the data. I use Photoshop and Illustrator quite a bit and I would like to use the 5400rpm drive as the scratch disk as well.
However, I'm not to familiar with read/write processes and I'm wondering if I will see a speed decrease if I use the 5400rpm drive to house the data while leaving the SSD open for the OS and all applications. Should I expect a noticeable decrease in battery life with both hard drives installed as well?
recently installed and flashed a sapphire 4890 into my mac pro 1,1.Installed Quartz update for 10.6.4, running dual displays no problems BUTTTTT.......something seems fishy about my open gl scores.Most of the people I've seen on here are scoring over a 1000 when benchmark is check in open gl viewer
I'm looking to replace my current external drive with a newer, larger drive. My current drive is connected via Firewire and houses my iTunes library, plus movie files, documents, etc. I'm trying to decide between a portable drive (the Western Digital Passport, for example), and another desktop drive (like say, this one [URL:..]Questions I have:
- Is there any reason to be concerned about longevity when using a portable drive? - Does a desktop drive typically perform better than a desktop drive? - Is there a noticeable speed difference between USB 2.0 and Firewire?
I just purchased my macbook pro 13inch (mid 2014) from a IT fair, 2 days ago and charged it ONCE to 100%. However, today when i checked my charge cycle, it reflects 3. Is this normal?
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?
I 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?
I 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 loved and cherished my MacBook Air for two years now, but last night it went in to a reboot cycle for no apparent reason. Now every time it gets to the apple logo I get the rotating "thinking" ident under the apple logo and it restarts, continually. I did the hardware test (holding down "D".....that was fine.) I also reset the PRAM... so the troubleshooting keystrokes work.
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?
My 11 month old macbook pro (2011) was recently sent under warrenty for Harddisk SPIN RETRY COUNT value increase. They changed the harddisk and installed new Toshiba harddisk. Which ran 100% S.M.A.R.T health for two weeks and now it is showing same Spin retry count problem. I am thinking its not the harddisk but something else is causing the problem( may be power supply problem). I am from nepal so it takes a lot of effort to send it in for repair.
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..
