Battery, what is good?

My macbook has been turning off earlier than it used to, but not so much that it's a problem yet. I came on here and saw all the posts about batteries, and it made me realize I don't know what's good or bad. I got my macbook in july '07 and this is the information I just looked up:
Battery Installed: Yes
First low level warning: No
Full Charge Capacity (mAh): 3365
Remaining Capacity (mAh): 1661
Amperage (mA): 1574
Voltage (mV): 12129
Cycle Count: 576
I don't know what any of this means! (I'm clearly not tech-savvy) Am I in good shape? Or am I in trouble? Thanks guys

i'd probably *double yikes* that!!!
i've had my trusty late 2006 MacBook since Feb. of 2007 and when i recently checked my battery via "coconut battery", it said something like:
initial charge: 4255 mAh
full charge: 4432 mAh (yeah, it now has a higher higher full capacity!)
and cycle count was only 27.
(i use my laptop, pretty much everyday... and it's usually plugged in, unless i am calibrating it.)
go back afew posts and look for First Magnus' excellent reply re: battery optimization... or, wait... i'll see if i can find themj for you!

    Hello Apple!
    What is good % battery point I can charging IPad 4?

    You can charge your iPad at any point no matter where the battery indicator is. I charge my iPad every night. This might be helpful.

  • Whats a good mac to use for a home flight simulator with flight controls and foot pedals?

    whats a good mac to use for a home flight simulator with flight controls and foot pedals?
    My old 6100 AV worked great on A10 ATTACK, back in 1993.
    whats a good set up now a days?
    I havent seen any MAC set ups as a lot of the after market accessories are on  Windows platform.
    Is there a way or should I get a dedicated simulator on PC?

    The fact that USB flight input devices appear to Windows only is not a limitation; for Mac most are programmed through the sim itself. I know X-Plane does that.
    I've simmed a lot and know that good sims need a lot of processor and video hardware horsepower, and you'll also need a lot of RAM. They also run up the internal temps. A Mac Pro has better cooling than an iMac. You can get a program like SMCFanControl to manually set up the fans speeds before starting the sim.
    I know of no sims today that will still run on a PowerPC Mac (2005 and earlier) so you need to look to an Intel Mac with top specs. If looking at iMacs, start by looking for the quad-core i7 processor. Those models usually came with an up-rated video card. Thing 12 to 16GB RAM.
    My 2010 iMac has the 2.93gHz i7 processor, video hardware (ATI 5750) with 1TB VRAM, and 12 GB of RAM. It runs the x-Plane 10 demo fine but I've not bought the full version because v10 seems to make foot pedals darned near mandatory, and I don't want $100 worth of pedals under my regular work desk at the moment.

  • Battery is not charged after using all of my battery. what's wrong? is it about charge machine or my computer?

    battery is not charged after using all of my battery. what's wrong? is it about charge machine or my computer?

    battery is not charged after using all of my battery.
    Of course it isn't — you've just drained it. Plug your AC adapter in and charge it up again.

  • My macbook pro has service battery, what could happen if i upgrade the ram to 8gb

    My macbook pro has service battery, what could happen if i upgrade the ram to 8gb

    "Service Battery" means just that - you need to make an appointment with your local Apple Store or AASP and have the battery checked out and, likely, replaced.
    If you upgrade to 8GB it will have no effect on the battery. 8GB is sort of the minimum that I would shoot for.

  • Whats a good anti-virus to install on my Mac?

    whats a good Anti-Virus to install on my Mac,either a free version or a paid version?

    I have used ClamXav for years, and can recommend it. While it's free, it doesn't hurt to donate something to the developer that maintans it.  http://www.clamxav.com

    Place the iOS device in Recovery Mode and then connect to your computer and restore via iTunes. The iPod will be erased.

    If recovery mode does not work try DFU mode.

    For how to restore:
    iTunes: Restoring iOS software
    To restore from backup see:
    iOS: How to back up     
    If you restore from iCloud backup the apps will be automatically downloaded. If you restore from iTunes backup the apps and music have to be in the iTunes library since synced media like apps and music are not included in the backup of the iOS device that iTunes makes.
    You can redownload most iTunes purchases by:
    Downloading past purchases from the App Store, iBookstore, and iTunes Store      
    If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

  • What are good quality speakers to purchase for mini mac

    what are good quality speakers to purchase for mini mac?

    While I can't recommend any brand of camera, you should consider a couple of things about the editing... iMovie 8 is a good program to use if you just need to create something quickly with little real editing and sound manipulation. And iM 8 will interface with both DV tape cameras as well as hard disk/flash drive types as well. You can export the product to web services, etc very easily but it will take some extra effort to create a DVD from the edited shots. There is no direct export to iDVD.
    If you want to get more serious about editing, you should consider looking iMovie 6 as it has much more flexibility in rearranging clips, adding and editing sounds, etc. However, it will only interface with DV tape cameras, which by the way, are the highest quality pics available, and you can create DVD disks.
    You might try borrowing a tape camera to make a test run and compare it to a camera that uses a HD for storage. Use iM 8 and compare to ease, etc, and the product to one created in iM 6. This certainly is not the kind of recommendation you are asking for, but maybe will help in making your decision about which way to go.

  • What is good for performance calculation in select st. or in formual column

    Dear Friends,
    I would like to ask you regarding what is good for performance specially i'm developing reports for EBS .
    is it better to calcualte total of 5 columns in select statment directly or using formula columns to do this,
    Regards & Thanks
    Yas

    I'd focus on easily readable query, namely use formula column if otherwise the query get too long or too complicated to read/maintain. Have inherited many ugly long queries/reports and hate to maintain or fix bugs for them etc.

  • What is good anti virus software for the mac?

    What is good antivirus software for the Mac?  I think I've been hacked. 

    ClamXav from http://www.clamxav.com . Be cautious of other antivirus software as some, not all just some, can cause system issues.  I've used ClamXav for years with no issues with it.
    By the way, you may get some responses to this question along the lines of "there are no mac virus's so you don't need antivirus software". While it's true there are no mac virus's today, in my opinion, it's like the stock market in that past performance is not a guarantee for the future.
    If you scan these discussions, you'll find hours of reading on this question ....

  • What is good software to download to remove duplicate files?

    What is good software to download to remove duplicate files? Mostly photos.

    Hi Marcusito12,
    Theoretically you can use the preinstalled software from Toshiba, the Toshiba Disc Creator. With this tool you can also burn CDs/DVDs.
    In my opinion its not necessary to pay for such a software. There are pretty well freeware software to download, like CD Burner XP. Thats my personal favorite, because its a small tool (doesnt need much disk space and RAM), can burn everything and its freeware.
    Check this!!!
    Furthermore I use DVD-R mediums from Verbatim and TDK CD-R.

    Malware bytes is an excellent free program. Microsofts Malicious Software Removal Tool is another excellent free program.

    I am unaware of an all in one tool as your requesting that is free. However, you can cover your basis with just a few freeware tools.
