The effect of the processor, memory and flash hd on battery

Hello,
I am about to by MBA 13.
I am not sure whether to get the basic version (i5, 4GB 128), or upgrade some/all of the components (to i7, 8GB, 256, respectively).
What effect will these improvements would have on the battery?

The only thing that will affect the battery is the CPU upgrade and there are mixed reports on how much of an impact the i7 has. It varies from seriously less battery life on a charge to marginally better battery life than the i5 model. Whether you'll actually notice the faster speed of the i7 processor also varies. From my own experience using them and talking to customers I rate the importance of the possible upgrades as:
8GB RAM - absolutely do it
256GB SSD - if you can afford it the resale value later will be rewarded and the added cost of getting an aftermarket upgrade is very step (and warranty voiding)
i7 CPU - if you have money to burn or if you are performing heavy CPU need tasks (and if so why aren't you looking at the rMBP?)

  • I was using my ipad it was under 10% but no under 4% it turned off then i pluged the charger in and flashed on then showed apple sign after i turned it on. now its going back and forth from the apple sign and battery symbol ive changed chargers its not on

    hey please help!
    i was using my ipad it was under 10% but no under 4% it turned off then i pluged the charger in and flashed on then showed apple sign after i turned it on. now its going back and forth from the apple sign and battery symbol ive changed chargers its made no differnce its been like 3 hours ive tried to do that reset thing holding lock button and home button for 10 seconds at the same time. WHAT DO I DO?

    Could be the charger, cable or iPad. Plug the USB cable into your computer. It may say "Not Charging", however, it is charging slowly and will verify that the cable is good.
    Try this first - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
    The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W (5W on Mini) USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (2.5W, most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
    Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
    How to Calibrate Your Mac, iPhone, or iPad Battery
    http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
    At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

  • Ipod will only getto the unhappy pic and then to a battery pic.

    My brand new ipod video has recently taken a turn for the worst, when i try to turn it on it only getsto the unhappy logo and then to a battery logo. i've alredy tried to restart, it wont go in to disk mode, and nothing on my comp will recognize it. what should i do, of course instead of throwing it against a wall?

    Hello,
    If a sad iPod icon or an exclamation point and folder icon appears on your iPod’s screen, or with sounds of clicking or HD whirring, it is usually the sign of a hard drive problem and you have the power to do something about it now. Your silver bullet of resolving your iPod issue – is to restore your iPod to factory settings.
    http://docs.info.apple.com/article.html?artnum=60983
    If you're having trouble, try these steps at different levels one at a time until the issue is resolved. These steps will often whip your iPod back into shape.
    Make sure you do all the following “TRYs”
    A. Try to wait 30 minutes while iPod is charging.
    B. Try another FireWire or USB through Dock Connector cable.
    C. Try another FireWire or USB port on your computer .
    D. Try to disconnect all devices from your computer's FireWire and USB ports.
    E. Try to download and install the latest version of iPod software and iTunes
    http://www.apple.com/ipod/download/
    http://www.apple.com/itunes/download/
    F. Try these five steps (known as the five Rs) and it would conquer most iPod issues.
    http://www.apple.com/support/ipod/five_rs/
    G. Try to put the iPod into Disk Mode if it fails to appear on the desktop
    http://docs.info.apple.com/article.html?artnum=93651
    If none of these steps address the issue, you may need to go to Intermediate level listed below in logical order. Check from the top of the lists to see if that is what keeping iPod from appearing on your computer in order for doing the Restore.
    Intermediate Level
    A. Try to connect your iPod with another computer with the iPod updater pre-installed.
    B. Still can’t see your iPod, put it in Disk Mode and connect with a computer, instead of doing a Restore on iPod Updater. Go and format the iPod instead.
    For Mac computer
    1. Open the disk utility, hope your iPod appears there (left hand side), highlight it
    2. Go to Tab “Partition”, click either “Delete” or “Partition”, if fails, skip this step and go to 3
    3. Go to Tab “Erase” , choose Volume Format as “MAC OS Extended (Journaled), and click Erase, again if fails, skip it and go to 4
    4. Same as step 3, but open the “Security Options....” and choose “Zero Out Data” before click Erase. It will take 1 to 2 hours to complete.
    5. Eject your iPod and do a Reset
    6. Open the iPod Updater and click “Restore”
    For Window computer
    Go to folder “My Computer”
    Hope you can see your iPod there and right click on the iPod
    Choose “Format”. Ensure the settings are at “Default” and that “Quick Format” is not checked
    Now select “Format”
    Eject your iPod and do a Reset
    Open the iPod Updater and click “Restore”
    In case you do not manage to do a “Format” on a window computer, try to use some 3rd party disk utility software, e.g.“HP USB Disk Storage Format Tool”.
    http://discussions.apple.com/thread.jspa?threadID=501330&tstart=0
    C. Windows users having trouble with their iPods should locate a Mac user. In many cases when an iPod won't show up on a PC that it will show up on the Mac. Then it can be restored. When the PC user returns to his computer the iPod will be recognized by the PC, reformatted for the PC, and usable again. By the way, it works in reverse too. A Mac user often can get his iPod back by connecting it to a PC and restoring it.
    Tips
    a. It does not matter whether the format is completed or not, the key is to erase (or partly) the corrupted firmware files on the Hard Drive of the iPod. After that, when the iPod re-connected with a computer, it will be recognized as an fresh external hard drive, it will show up on the iPod updater.
    b. It is not a difficult issue for a Mac user to find a window base computer, for a PC user, if they can’t find any Mac user, they can go to a nearest Apple Shop for a favor.
    c. You may need to switch around the PC and Mac, try to do several attempts between “Format” and “Restore”

    Advance Level
    A. Diagnostic mode solution
    If you have tried trouble shooting your iPod to no avail after all the steps above, chances are your iPod has a hardware problem. The iPod's built-in Diagnostic Mode is a quick and easy way to determine if you have a "bad" iPod.
    You need to restart your iPod before putting it into Diagnostic Mode. Check that your hold switch is off by sliding the switch away from the headphone jack. Toggle it on and off to be safe.
    Press and hold the following combination of buttons simultaneously for approximately 10 seconds to reset the iPod.
    iPod 1G to 3G: "Menu" and "Play/Pause"
    iPod 4G+ (includes Photo, Nano, Video, and Mini): "Menu" and "Select"
    The Apple logo will appear and you should feel the hard drive spinning up. Press and hold the following sequence of buttons:
    iPod 1G to 3G: "REW", "FFW" and "Select"
    iPod 4G+ (includes Photo, Nano, Video, and Mini): "Back" and "Select"
    You will hear an audible chirp sound (3G models and higher) and the Apple logo should appear backwards. You are now in Diagnostic Mode. Navigate the list of tests using "REW" and "FFW". The scroll wheel will not function while in diagnostic mode. For further details on Diagnostic mode can be found at http://www.methodshop.com/mp3/ipodsupport/diagnosticmode/
    Try to do the 5in1, HDD R/W and HDD scan tests. Some successful cases have been reported after the running the few tests under the Diagnostic mode. In case it does not work in your case, and the scan tests reports show some errors then it proves your iPod has a hardware problem and it needs a repairing service.
    B. Format your iPod with a start disk
    I have not tried this solution myself, I heard that there were few successful cases that the users managed to get their iPod (you must put your iPod in disk mode before connecting with a computer) mounted by the computer, which was booted by a system startup disk. For Mac, you can use the Disk Utility (on the Tiger OS system disk), for PC user, you can use the window OS system disk. Try to find a way to reformat your iPod, again it does not matter which format (FAT32, NTFS or HFS+) you choose, the key is to erase the corrupted system files on the iPod. Then eject your iPod and do a Reset to switch out from Disk Mode. Reboot your computer at the normal way, connect your iPod back with it, open the iPod updater, and hopefully your iPod will appear there for the Restore.
    If none of these steps address the issue, your iPod may need to be repaired.
    Consider setting up a mail-in repair for your iPod http://depot.info.apple.com/ipod/
    Or visit your local Apple Retail Store http://www.apple.com/retail/
    In case your iPod is no longer covered by the warranty and you want to find a second repairing company, you can try iPodResQ at your own risk
    http://www.ipodresq.com/index.php
    Just in case that you are at the following situation
    Your iPod warranty is expired
    You don’t want to pay any service charges
    You are prepared to buy a new one
    You can’t accept the re-sell value of your broken iPod
    Rather than leave your iPod as paper-weight or throw it away.
    You can try the following, but again, only do it as your last resort and at your own risk.
    Warning !!!! – It may or may not manage to solve your problem, and with a risk that you may further damage your iPod, which end up as an expensive paper weight or you need to pay more higher repairing cost. Therefore, please re-consider again whether you want to try the next level
    Last Resort Level
    1. . Disconnecting the Hard Drive and battery inside the iPod – Warning !! Your iPod warranty will be waived once you open the iPod.
    In Hong Kong there are some electronic shops offering an iPod service for Sad iPod, the first thing they do is to open up the iPod’s case and disconnecting the battery and the Hard Drive from the main board of the iPod. Wait for 5-10 minutes and reconnecting them back. The reason behind which I can think of is to do a fully reset of a processor of the iPod. In case you want do it itself and you believe that you are good on fixing the electronics devices and have experience to deal with small bits of electronic parts, then you can read the following of how to open the iPod case for battery and HDD replacement (with Quicktimes)

    2.Press the reset button on the Hard Drive inside the iPod – Suggestion from Kill8joy
    http://discussions.apple.com/thread.jspa?messageID=2438774#2438774
    Have I tried these myself? No, I am afraid to do it myself as I am squeamish about tinkering inside electronic devices, I have few experiences that either I broke the parts (which are normally tiny or fragile) or failed to put the parts back to the main case. Therefore, I agree with suggestion to have it fixed by a Pro.

  • Adobe Flash is not working no matter what I do - I have updated Firefox to the latest version and Flash to the latest version to no avail - what can be done?

    I have used your help processes and done everything that is suggested - repeatedly. I don't know what else to say. Whenever I go to a site requiring the use of adobe flash, the system freezes up for a couple of minutes or more and then it says that Flash has crashed. I have sent the crash reports multiple times. When I use Internet Explorer, I have no issues with Adobe Flash. I have Windows 7 64bit installed.

    I had loads of problems with iTunes, could see all but it would not respond at all.
    I downloaded Abexo free registry cleaner and Errorkill registry cleaner free for limited period with restrictions. I ran both and got rid of all the junk in the registry and then installed QuickTime standalone...all problems solved. May need to reinstall itunes AFTER Quicktime if this does not work.
    Hope this helps.

  • Problems with the processor , fan , and energy consumption

    Hello .
    Well , for some reason , my two years old laptop started to behave in a weird way . I just ignored the slight slowdown with the boot because I believe it's to be expected with any machine but that's not the issue . Aside from the annoying fact that Windows 7 doesn't seem to make full use of the RAM and thus it only uses HALF - yes , HALF - of my 6 GB RAM , my PC seems to slow down regulary while I browse the internet . I recently knew about the task manager and decided to take a look to be shocked at how much RAM Firefox and Google Chrome use . Along with other necessary system tasks - which almost don't count - , they alone take 30% of the RAM capacity . That's unfortuenately isn't the issue either because I can close any of them when I want to work on other stuff . The issue here is that for no apparent reason , my processor seems to work harder than is necesarry even when the programs I see in the task manager don't need 5% of it's full potential ! With such work it heats up . On Toshiba Health Monitor I see it going to 70-75% in heat and the fan kicks up to 85% to cool it down . Of course , that leads to rapid power consumption that can suddenly shoot from 17% to terrible 60% with ABSOLUTELY NO PROGRAMMS CURRENTLY AT WORK ASIDE FROM WINDOW EXPLORER .
    The good thing is that it doesn't happen all the time but it still worries me . Any ideas ?

    See my post on your other thread to obtain your model and part numbers. It's difficult to discuss your unit's use of RAM and other problems without that info.

  • I like to play games on facebook and for some reason I keep getting an error message saying that the shockwave player and flash player has crashed I use firefox could someone please give me step by step instructions to fix this issue?

    I have Windows 8.1, my adobe player is the most updated version also.... hope this helps

    Yeah, Firefox and Flash Player isn't a super stable combination on Windows 8.1 at the moment.  We're collaborating closely with Mozilla to improve that, but that effort is going to happen over several months.
    In the meantime, you might want to take a look at the other options.  Microsoft invested a lot of time and effort into making the Flash experience on Win8.1 really good in IE, as did Google with Chrome.

    I have a setup similar to yours (384 MB instead of 512 MB),
    and I spent some time looking at the parameters.
    You CANNOT use the value for SHMMAX from the Oracle manual!
    As it says at http://jordan.fortwayne.com/oracle/oralinux.html
    "Should you decided to change these parameters, if you set
    the SHMMAX to what Oracle says, you are telling the system
    to allow a shared memory segment to grow as large as 4 Gigs.
    Many users have reported problems setting the value this
    high."
    Sounds like you are another one of those users, eh?
    If you read on down, the guy who wrote that web page never
    used over 128 MB for SHMMAX. I'd take a strong hint from that.
    =====
    Oracle wants you to use 4GB-1 as the SHMMAX value. That
    equates to (1<<32)-1. As we shall see, that is not allowed
    without "breaking the rules" for the i386 architecture.
    If you carefully read through the header file, you will find
    out that the **actual maximum value** for SHMMAX is 256 MB.
    You can tell this two ways. Take a look at the file at:
    /usr/src/linux/include/asm/shmparam.h
    Near the top of the file is:
    /* address range for shared memory attaches if
    no address passed to shmat() */
    #define SHM_RANGE_START 0x50000000
    #define SHM_RANGE_END 0x60000000
    Note that the above is 256 MB (0x10000000), or (1<<28). This
    is one potential source of trouble. I don't know if some other
    files someplace else in the kernel specify uses for address
    ranges adjacent to the above range, which I take to be the
    "practical maximum" without redefining that range. Personally,
    I wouldn't want to mess with the above unless I **really**
    knew what I was doing (and I'll be the first to admit I don't).
    =====
    Farther down you will see some more lines (not together)
    that look like this:
    #define SHMID_BITS 7
    #define SHMIDX_BITS 15
    * SHMID_BITS + SHMIDX_BITS must be <= 24 on the i386 and
    * SHMMAX <= (PAGE_SIZE << SHMIDX_BITS).
    #define SHMMAX 0x2000000 /* max shared seg
    size (bytes) */
    Now, 7 + 15 is 22, so you could go up a couple of bits if you
    had to. To avoid making the table any larger, I would suggest:
    #define SHMIDX_BITS 17
    But, 17 turns out to produce a result larger than the "practical
    maximum" (256 MB) above. To see why takes a little more
    explaining.
    If you don't change this at all, then the maximum possible
    value for SHMMAX is 4096 [the PAGE_SIZE) << 15 [_SHM_IDX_BITS],
    or rather (1<<27).
    Now, that is exactly half of the (1<<28) "practical maximum" I
    mentioned above.
    So, if you always want the maximum amount of shared memory,
    then change the definition of SHMMAX to the following:
    #define SHMMAX (PAGE_SIZE<<_SHM_IDX_BITS) /* max shared seg
    size (bytes) */
    That gives you 128 MB in and of itself (as compared with 32 MB
    as Red Hat 5.2 is delivered).
    If you want the full 256 MB that is allowed for in the memory
    map, then you need to also change:
    #define SHMIDX_BITS 16
    The above value is **exactly** what is recommended on the web
    page you were following (above).
    If you want to keep going up, you will need to change the
    memory space allocated for shared memory as defined by
    SHM_RANGE_START and SHM_RANGE_END, something I advise against.
    =====
    Even on a machine with 512 MB of "real" memory, I find it hard
    to believe that there would be any substantial benefit to
    having a maximum shared memory space greater than 256 MB. The
    reason is that Oracle can use multiple shared memory spaces.
    It requires a minimum of ten (10), according to the installation
    manual, but the Red Hat 5.2 distribution supplies SHMMNI (128)
    of them. That will allow each Oracle process to have a total
    of up to 32 GB of shared memory (128 times 256 MB) and all it
    asks for is 40 GB (10 times 4 GB), so it has plenty, IMHO.
    =====
    Let me say a few more words about the web page you were using
    for configuration advice. That person actually **reduced** the
    amount of shared memory segments by specifying **lower values**
    for SHMMNI and SHMSEG.
    I'd **STRONGLY** recommend **NOT CHANGING** those other values!
    Its my understanding that Oracle can make up for the smaller
    maximum shared memory segment size by using more shared memory
    segments. So, if you reduce those, you are essentially shooting
    yourself in the foot by taking away what you are giving with
    increasing the maximum segment size.
    =====
    Good luck, and may this farce be with you!

  • Memory and Flash

    Really really stupid questions ,
    what is the difference between RAM and Flash and Memory (in Cisco world)?
    How much of what I have? (see config below)
    What is the maximum flash and RAM and memory allowed for 2511 router?
    Thanks a million !!!!

    Memory is a really broad term and could reference both RAM and flash, though when used by itself memory usually refers to RAM. RAM is Random Access Memory and a couple of important things about RAM is that it is faster and that it is volatile so that when the router is reloaded or is power cycled the content of RAM is erased. flash is slower and is non volatile memory so that the content of flash are maintained through a reload or power cycle.
    Your router has 64 MB of RAM and has 8 MB of flash.

  • How do you clean the entire memory and start over

    how do you clean off the memory in order to start over

    Why are you asking on the Apple forums?

  • My computer does not have the processor requirements for Flash 14. I can not play any videos or do school work. What version can I get with a processor of 2.1GHz?

    I need a version of flash that will allow me to watch videos and have access to school before July 2nd. What version can I download to do this and how do I download it? I am getting frustrated.

    here are older versions, Archived Flash Player versions

  • The constant update of Java and Flash in a managed account

    First off sorry if this question has been answered, I had tried a search and could not find it.  I have a lab of machines (Maverick with managed accounts) that uses Jar files and Flash applets that are downloaded to the desktop.  I would update the machines on a Friday for these internet plugins.  But then another update, either Flash or Java, will roll on the weekend and the browser is useless on Monday because Safari refuses to load the jar file or flash applet and Firefox will download corrupt jar files.  So the students cannot just use one browser.  I would prefer Firefox since it is more forgiving on the flash and allows me to have time till the end of the week to update but now there is an issue of the jar.  How can I make it that the java console and Flash will automatically update in the managed account or allow the person to update only these applications and it would not matter which browser is used?  Is there a way to use Automator for this, I have a feeling it is a no but I want to be sure?  Or is there a way on the firewall to prevent it from checking in the browser for the updates?  This is a little frustrating for there seems to be an update more then two or three times in a month and rendering the machine useless for lab.

    (Released 4/16/2014) Flash Player 13.0.0.201 (Mac only) (44.67 MB)
    That has the fixed Flash 13.0.0.201 plug-in and the debugger. in it. You just need to run the regular installer from that zip file.

  • Where is the ROM memory, input and output devices located on personal computers (laptops)

    I have an assignment due that requires I locate the ROM memory and input/output devices. Where can i find these items?
