Keeping your battery lengthy and healthy

This might seem repetitive but what are the absolute best ways to extend life:
I have it set to better energy savings no bluetooth and low display backlight (half way)
Am I missing something out?
2. I've read the battery callibration sheet but nothing is specified about what power settings should be used ? Does it matter? It could take a while to drain fully therefore I would Crank up the brightness
Thanks in advance for your help
Ben

Set your brightness as low as you can stand it - the difference between 1 bar of brightness and 8 bars will have a significant impact on your battery. I don’t know if he is correct, but the head tech where I work told me that the ethernet port can be turned off in the Network Control Panel to reduce power consumption and that the sound circuit can be turned off by turning sound down all the way which also reduces power consumption. Make sure you don’t have a disk in the optical drive and if possible launch all the programs you’ll use before disconnecting the power adapter. Doing all this I’m getting better than 4 hours on a charge even though WiFi is on all the time.
The same head tech told me that while calibrating the battery you should not drain it as quickly as you can but, just the opposite, you should drain it as slowly as you can. Again, I don’t know if he is correct but over the years I’ve known him to be correct more than not.

    To be honest, I would only plug it in when necessary. On my older 2009 MBP, I plug it in at night and it lasts me a solid 5-6 hours, if it needs to be plugged in during the day, I usually do it with about 2-3 hours left.

  • Please Advise On The Best Way To Keep Your Battery Healthy And Not Deformed

    I am a black macbook (mb) user and have had my mb for 37 months now. after a year and a half, my battery (the first one) was deformed and i was advised to replace it quickly. i was also advised to calibrate my battery occasionally and so i did after that. but in just over a year after i replaced my battery, it is starting to deform and swollen. i have been following the advice and calibrated my battery as advised. my battery is still in normal condition according to the system profiler.
    when i first bought my macbook, i was told NOT TO keep recharging my battery whenever i used it and the battery drains because this would make the battery's life shorter. i was also told it is OKAY to have the power plugged in. and so i did that. but it turned out that my battery had deformed from it. most probably from the heat but i don't know.
    i use my macbook regularly. i keep it switched on almost 24 hours a day and i keep it well ventilated (i sit it on top of iLap) because i have my internet on 24 hours a day and use the internet regularly. i am not planning to replace my battery just yet even though the battery capacity has gone down to 77%. it's expensive here. i will keep on continuing with the calibrating every now and then. now it might be the magsafe's problem that the battery is deforming too soon. one time, the magsafe fell from my bed onto the floor quite hard. and since then it wasn't working properly. sometimes it heats up and it becomes too hot to hold for long. at times the battery would say 0:00 (time left charging) but the light doesn't change to green so i have to plug it out from my mb and from the main plug and rest it for about 10 seconds and then it runs as normal. i know i probably need to change the adapter soon.
    anyway, i'm just asking. for someone who uses his mb regularly or everyday and almost 24 hours a day, what is your best advice on how to keep the battery healthy and in good condition for a long period of time?
    sorry for the rambling but thank you.

  • RGB CMYK PDF EXPORT.(colour conversion)  Keeping your colours vibrant and your blacks black.

    Ive been tearing my hair out for the best part of 14 hours trying to figure out how to keep the closest possible conversion for working with images(rgb in photoshop) right the way through a work flow until exporting to print (having used the image in Indesign).  Here is the process I have been trying to get right.
    1) working with RGB photo images in photoshop and converting them to CMYK (whilst holding on to as much colour as poss)
    2) Importing them to Indesign and retaining the correct colours while working with them)
    3) Exporting to high quality print and having all your colours stay 100% the same as you saw them within indesign.
    I believe I have the solution so I posted my settings below to see if its the best way of doing things and to help others who might be having the same problems.
    The problem
    The problem is that there are many different colour models/profiles (both in RGB and CMYK) and each program can effect how the next one handles and stores colour.  It can become frustrating knowing where to go in order to set the settings correctly  as the combination of things to consider can make it confusing.
    I understand many other people have similar problems and finding RGB blacks come out as grey.  CMYK spaces get converted from one type to another either from one program to the next or even as things move around one program (causing all sorts of wonderful,colour errors)  Plus you have imported colour profiles, working colour profiles and export profiles.  All of which can interact and effect each other) So getting it all consistent is key other wise colours change and get washed out.   Especially vibrant colours like greens and blues. they fade etc.
    Through sheer trial and error and perciverance I found a combination of settings that worked well for me.
    Since I am not an expert I wanted to post up my settings to:
    1) see if this is the best way of doing things.
    2) Other people may find them useful if they had the same problems I had,
    The Solution
    In photoshop
    Save the photoshop image in CMYK by selecting:
    Edit > Convert to prfile.
    (in destination space)
    select: Euroscale Coated v2   (I think this holds the colours the truest of all CMYK colour formats.)
    (in conversion options)
      - Engine: Adobe ACE
      - Intent: Perceptual.
      - Check Use black point Compensation.
    (leave all else unchecked)
    Save the image ready to place in indesign (place rather than copy and paste.).
    In Indesign
    edit > colour settings   (make sure you click on the advanced tick box to open more options)
      - Working space: =
      - RGB:  sRGB IEC....
      - CMYK Euroscale coated v2
      - RGB & CMYK convert to working space.
      - Engine Adobe ACE
      - Perceptual
      - Use black point compensation
    edit > Assign profiles
      - RGB profile. > Assign current workspace: sRGB IE
      - CMYK > Assign current work space Euroscale Coated V2
      - Solid colour intent : preceptual
      - Default image intent
      - After blending intent:  Perceptual.
    edit > convert to profile.  (use similar as above).
    edit > Preferences > Apprearance of black
      - on screen / export : Display all blacks as enriched black
      - Priniting and export : Display all blacks as enriched black
    Overprint: (not checked)
    ------ when exporting to PDF ----------
    File > Export
    in GENERAL TAB
      - Adobe PDF preset: High quality print.
      - Standard (drop down menu): PDF/X-42008
      - Compatability: Acrobat 5 PDF1:4
    in OUTPUT
      - COlour conversion: Convert to destination
      - Destination:  Working CMYK Euroscale Coated v2
    in PDF/X
      - Output intent profile name: Working CMYK - Euroscale Coated v2
    also:
    If you are having problems with fill blacks not coming out as proper black then use registration instead of black from the swatch panel.
    The above may seem either obvious to most of you or possibly not the best way of doing things but since the results worked for me and I found them tough to arrive at, it may be of use to others hence my post.
    I would like your feedback on this process, have I done something wrong / could do better?  If so please let me know.  I am keen to improve.

    I would copy and paste into InDesign forum. Text should stay 100% black. Any other black (like solid boxes or thick lines), I usually use a rich black swatch I created at 40/40/40/100. Looks 10 times better than just 100% black.

  • Nokia 5000 - How much time keep your battery

    Hi, please can you let me know how much time (days of hours) you baterry is workin on. On my Nokia 5000 the baterry work fine for 3 or 4 days, including the stand by tine and talking time. The talking time is not more then 30minutes - 1 hour per day.
    Thank you very much.

    Read the manual about battery life.  There are many factors that can cause excessive battery drain.  Thing such as:
    Push for mail.  You might want to turn push off and check for manually
    You mention you have a WiFi unit.  If you leave WiFi on and you're not near a WiFi signal, your unit will constantly check for a WiFi signal
    Location Services uses battery power.  Check your settings and turn off location for Apps that don't need your location
    These are just a few suggestions.

    You have  DiskUtility to run periodicly for your basic good house keeping.  As for as fast I would recommend 8GB of RAM.
    I would recommend Installing AppleJack -

  • If i download CAD software how will it affect my battery life and macbook speed?

    If i download CAD software how will it affect my battery life and computer speed?

    Welcome to Apple Support Communities
    CAD software requires the best CPU and GPU performance, so your battery life will be affected while running CAD apps. The same will happen with your computer performance with other apps, so if you do not need any application while using CAD apps, it is better to close them.
    However, your battery life and your computer performance will be the same if they are closed. The only exception would be if your MacBook's hard drive is running out of free space

    I already tried rebooting, and I tried hooking it up to itunes as well, no luck there either.

    Try to reset all settings.

    When you say reboot, do you mean you pressed the home and sleep button at the same time until it restarted? 

  • Keeping your mac healthy

    How can i know if my mac is healthy and how can i keep track on how its doing?

    How to maintain a Mac
    1. Make redundant backups, keeping at least one off site at all times. One backup is not enough. Don’t back up your backups; make them independent of each other. Don’t rely completely on any single backup method, such as Time Machine. If you get an indication that a backup has failed, don't ignore it.
    2. Keep your software up to date. In the Software Update preference pane, you can configure automatic notifications of updates to OS X and other Mac App Store products. Some third-party applications from other sources have a similar feature, if you don’t mind letting them phone home. Otherwise you have to check yourself on a regular basis. This is especially important for complex software that modifies the operating system, such as device drivers. Before installing any Apple update, you must check that all such modifications that you use are compatible.
    3. Don't install crapware, such as “themes,” "haxies," “add-ons,” “toolbars,” “enhancers," “optimizers,” “accelerators,” “extenders,” “cleaners,” "tune-ups," “defragmenters,” “firewalls,” "barriers," “guardians,” “defenders,” “protectors,” most “plugins,” commercial "virus scanners,” "disk tools," or "utilities." With very few exceptions, this sort of stuff is useless, or worse than useless.
    The more actively promoted the product, the more likely it is to be garbage. The most extreme example is the “MacKeeper” scam.
    As a rule, the only software you should install is that which directly enables you to do the things you use a computer for — such as creating, communicating, and playing — and does not modify the way other software works. Never install any third-party software unless you know how to uninstall it.
    The free anti-malware application ClamXav is not crap, and although it’s not routinely needed, it may be useful in some environments, such as a mixed Mac-Windows enterprise network.
    4. Beware of trojans. A trojan is malicious software (“malware”) that the user is duped into installing voluntarily. Such attacks were rare on the Mac platform until sometime in 2011, but are now increasingly common, and increasingly dangerous.
    There is some built-in protection against downloading malware, but you can’t rely on it — the attackers are always at least one day ahead of the defense. You can’t rely on third-party protection either. What you can rely on is common-sense awareness — not paranoia, which only makes you more vulnerable.
    Never install software from an untrustworthy or unknown source. If in doubt, do some research. Any website that prompts you to install a “codec” or “plugin” that comes from the same site, or an unknown site, is untrustworthy. Software with a corporate brand, such as Adobe Flash Player, must be acquired directly from the developer. No intermediary is acceptable, and don’t trust links unless you know how to parse them. Any file that is automatically downloaded from a web page without your having requested it should go straight into the Trash. A website that claims you have a “virus,” or that anything else is wrong with your computer, is rogue.
    In OS X 10.7.5 or later, downloaded applications that have not been digitally signed by a developer registered with Apple are blocked from loading by default. The block can be overridden, but think carefully before you do so.
    Because of recurring security issues in Java, it’s best to disable it in your web browsers, if it’s installed. Few websites have Java content nowadays, so you won’t be missing much. This action is mandatory if you’re running any version of OS X older than 10.6.8 with the latest Java update. Note: Java has nothing to do with JavaScript, despite the similar names. Don't install Java unless you're sure you need it. Most users don't.
    5. Don't fill up your boot volume. A common mistake is adding more and more large files to your home folder until you start to get warnings that you're out of space, which may be followed in short order by a boot failure. This is more prone to happen on the newer Mac notebooks that come with an internal SSD instead of the traditional hard drive. The drive can be very nearly full before you become aware of the problem. While it's not true that you should or must keep any particular percentage of space free, you should monitor your storage consumption and make sure you're not in immediate danger of using it up. According to Apple documentation, you need at least 9 GB of free space on the startup volume for normal operation.
    Use a tool such as the free application OmniDiskSweeper to explore your volume and find out what's taking up the most space. Move rarely-used large files to secondary storage.
    6. Relax, don’t do it. Besides the above, no routine maintenance is necessary or beneficial for the vast majority of users; specifically not “cleaning caches,” “zapping the PRAM,” "resetting the SMC," “rebuilding the directory,” “running periodic scripts,” “deleting log files,” “scanning for viruses,” or “repairing permissions.” Such measures are for solving problems as they arise, not for maintenance.
    The very height of futility is running an expensive third-party application called “Disk Warrior” when nothing is wrong, or even when something is wrong and you have backups, which you must have. Disk Warrior is a data-salvage tool, not a maintenance tool, and you will never need it if your backups are adequate. Don’t waste money on it or anything like it.
