Should the FW 400 port be sending power to the FW HUB When the Mac is off?

The title says it all. I am using a refurbished 2007 Aluminium 20 inch IMac and after I shut down the Fire Wire ports still power the FW 400 Hub, is this normal? I have just stopped cutting power supply with surge protector because I was having trouble getting the Imac to start and leaving its' power supply on made the start up faultless. Could the "shut down" instead of "log out" be the cause?

Hey JustSomeGuy, thanks for solving the problem. The "cause" you were curious about is the choice when stopping to choose "shut down" instead of"log out", I'm not sure what the second one[log out] would do when I wanted to start the iMac again.
PS: my USB peripherals don't get enough power when the iMac is off to have them show lights indicating power, but I believe you are right. When I had the iMac in a surge protecter, so it was cut off completely from power it had BIG problems with starting up, for some reason the iMac must have access to power to always start up as it should.

  • How long should the Mac Book pro hold its charge???

    How long should the Mac Book pro hold a  battery charge??

    For a single use or how long will the battery last until it needs to be replaced?  For single use, it depends on what you are doing when using you mac.  I find that when using mine I get about 6-6 1/2 hours just using it to browse the internet before I need to recharge it.  If it is one of the newer Macbook Pros that claim to have a 7 hour battery life, It can last up to 5 years.  See this article on notebook batteries to get the most out of your battery: http://www.apple.com/batteries/notebooks.html.  Hope this helps

  • Why is iMessage taking my incoming emails and then not making them available for my PC to get?  Why can I not send a text msg with photos when iMessage is turned off (but MMS is still on).

    Apple is great!
    Why is iMessage taking my incoming emails and then not making them available for my PC to get?  Why can I not send a text msg with photos when iMessage is turned off (but MMS is still on).
    I compose an iMessage with the destination as my email address and I attach 2 photos I want on my PC.  I send them several times from my iPhone 5C but they never arrive. I look at my ipad later and realize that it's iMessage app is getting ( and swallowing) these emails. I then turn the ipad off.  Still can't get the photos through because iphone is now getting them on it's iMessage.  I turn off the iMessage feature and try to send photos from text msging.  Phone tells me it can't send photos unless iMessage it turned on.  What happened to regular MMS text messaging?  I go and try to send photos as an email attachment and see that there is no option to attach from the stupid email program.  I look up online to learn about the brave new world of apple attachments and send them.
    Why is iMessage taking my incoming emails and then not making them available for my PC to get?
    The email program on my iphone is not configured to remove messages from the server.
    If iMessage is turned off I don't have the issue.
    Why can I not send a text msg with photos when iMessage is turned off (but MMS is still on).

    Did not work. I've selected iMessage to ON and left it. After a few hours I recieved a message "activation unsuccessful. Turn on iMessage to try again". This has been going on for the past 3 days.

  • Apple TV Syncs Content from Mac, but cannot access it when the Mac is off

    I scanned the forums for a few hours and didn't see any answers to this question, so here it is.
    I sync'd the movies and pictures on my MacBook Pro to the the Apple TV; however, when the Mac sleeps, I cannot play or view the content on Apple TV until the Mac wakes up and reconnects to the network.
    When I go into iTunes and select the Apple TV, the content clearly shows up (15 GB+). I view Activity Monitor while movies play, and it appears to be playing the locally sync'd content because network utilization is almost zero. But, it insists on my MacBook being up with iTunes running.
    Has anyone else seen this?
    Thanks for any ideas.

    MacBook Pro   Mac OS X (10.4.9)  

    OK,
    Forget about iTunes, I am talking about the actual Apple TV itself.
    On the TV screen in the main ATV menu you will see a list - Movies/TV Shows/ Music.....ending with Sources.
    At the very top of this list you will either see a large ATV logo, or you will see the name of your iTunes library.
    If you see your iTunes library name - the reason you can't access anything when your computer is asleep is because this source is for streaming from your computer only. Scroll down to where it says Sources, select it and in the next menu you will see the ATV logo at the very top of the list - select it and you can now play the content that is stored on your ATV.
    Good luck!

  • Should the mac book be turned off if not in use?

    Does leaving the macbook powered on 24/7 cause problems? 

    You can leave it plugged in while sleeping...the Apple charging circuitry chareges the battery to 100% and then shutsdown and the unit uses line power until the battery trickles down to 93-95% at which point the circuit kicks in and tops up the battery, and shutsdown again.  Keeps doing that so it cannot overcharge the system.
    Personally, I don't like the thermal cycling of powering down and up frequently.
    If you keep it plugged in just remember to unplug and run the battery down about half way once or twice a month to exercise it.  Running the battery down to shutdown is not good for the battery.  Sudies have shown a battery discharged to 50% and recharged will have three to four times the life of a battery discharged all the way as a regular thing.

  • How many times should the computer cycle on-off when doing a factory reset?

    I have a Toshiba A665-S6065 which can not boot.  Yesterday I tried the Auto Recovery by holding the 0
    while booting, and following the default instructions.  It seemed to complete without errors.  But the computer
    will still not boot.  Today, when reading the instructions, it said to expect the computer to cycle on and off severa
    times.  So how many times?  will there be any propmts or messages?  How long should the entire process take?
    How long should the computer be off before it turns on again each time?  I think I might be screwing things up
    by intervening and trying to start the computer myself because it isn't clear to me what should actually be happening.
    Could someone please tell me what to expect before I start looking at possible hardwre problems?
    BTW, I can access the Setup and Boot Menu.
    Thanks,
    kjdroid 
    NEW info:
    Now when I boot while holding the 0 key, instead of going directly to the Recovery Wizard, it goes to the
    Windows Boot Manager.
    from there the options are Windows Setup [EMS enabled]
    and Windows Memory Diagnostic, as well as the F8 option for advanced options.
    If I select Windows Memory Diagnostic I get
    File: \boot\memtest.exe
    Status : 0xC000000f
    Info : The selected entry could not be loaded because the application is missing or corrupt.
    If I select Windows Setup or F8 followed by normal windows startup or startup in safe mode then
    I get the following sequence of events.
    Starting Windows with the Windows logo.
    then the blue screen
    Then to the Toshiba Recovery Wizard, where it partitions, and does the CRC and then prompts to press
    finish to restart the computer.
    Either the computer does not shut down, or it stops and starts very quickly because all the lights cycle
    on and off but it does not appear that the start/stop light actually ever turns off.
    Then I get the Starting Windows with Logo again.
    Then the Recovery Wizard comes back but only with the screen about partitioning.  It does not
    do the recovery and CRC this time.
    Nextis the Toshiba Logo reappears again with the options for F2 or F12 for the Setup and Boot Menus.
    Finally, I get a blue screen and it appears nothing else is happening.  I let it sit for 30 minutes before I retry, because I am not sure what is supposed to be happening now.
    Also, one of my attempts, I got as far as the messages:
    Setting up the Registry
    Starting Services
    Applying System Settings
    Will continue after restarting your computer
    Is preparing your computer for first use.
    But then again, it just goes into the blue screen state until I finally decide to shut things down.
    Am I being premature or should I let the blue screen sit there for a few hours while work is being
    done in the background?  I don't hear any sounds from the computer that would indicate any type of activity.
    Thanks again

    Actually, it's kind of hard to tell you what to replace. If you have a spare hard drive laying around, go for it. It also could be memory issues (I have the same model as you) & it was my sister-in-law's notebook before I get it. The notebook had several memory dumps that CCleaner found & deleted when I was working on it. 
    I told her that I would re-install it for her to make sure there no viruses or such. After backing up the computer, I proceeded to what was supposed to work, pressing "0" at startup to no avail, then booted into the area where the system restore, command line repairs & such were, & there was the option for a factory reset, the last option. I chose that one, & like you stated, it rebooted numerous times, until finally it was through. Longest factory re-install I've ever done. 
    What led me to believe there were memory issues was during the first round of updates, it BSOD'd, another memory dump was found by my portable CCleaner. It still had the original Samsung PC3-8500 memory, so I took the memory that shipped with my MSI (PC3-10600) & installed that, then not only was all fine, it was noticably faster. Once I got it fully updated & scanned with MBAM & the ESET Online Scanner (I always do this when installing or re-installing a computer), I removed my memory & placed hers back in, then returned it to her. 
    I ended up with it about 10 days later, she said it was still dumping. Needing a spare notebook, I offered $100 for it, ending up paying $150, but still came out way better than on eBay. 
    Once I got it, I placed the 6GB RAM back in there that I had, & also replaced the HDD with a extra Crucial M4 that was laying around. Right before swapping drives, I ran HD Tune (free) on the original, there were yellow attributes, meaning that it had issues pending. It's a 500GB Seagate HDD that runs at 7200 RPM. Just so happened, I lost a 500GB Seagate Barracuda desktop HDD (7200.11) less than a month ago. Booted the computer, the screen stated "No Operating System found". 
    So it could be either the HDD or memory (RAM). Or worse yet, the MB itself. Has it been dropped? Notebooks are fairly durable, but they don't take to being dropped very well. Does it run hot? If so, there may be severe dust buildup that's causing it to overheat, that will make it BSOD. My guess is that's it's one of the first three that I mentioned above & if it's the MB, forget it. Prices are too high, even for used ones & in a notebook, it's basically a total teardown to replace it. If it's a new MB, it may cost between $200 to $400, depending on popularity of the model. That's too much to pay to repair a computer built in 2010. 
    I'm trying to give some suggestions here, based totally on personal experience on my & other's computers that I work on. However, online it's a cat & mouse game. I don't want to tell you to purchase another HDD unless it's almost 100% certain that's the issue. Which is why I asked if you have a spare earlier. Also, try reversing the position of your memory sticks (a 5 minute job), it's behind that lid close to the battery underneath the notebook. 
    Post back if you need further assistance. Someone else may have other ideas, so follow the thread.
    Best of Luck,
    Cat

  • How do I install Yosemite on a 2nd HDD I have added and have the Mac Pro boot from the new HDD?

    My MacPro's HD seems to be failing. None of the tests I run indicate that, but I get constant spinning balls and everything takes a long time. I bought a 2nd HDD and installed it in the 2nd bayou my Early 2009 Mac Pro. I formatted it and want to install Yosemite and have the Mac boot off the new drive. It is currently running OS X 10.9.5. When I go to update to Yosemite it begins to download. Will it give me the option of which drive to install on? Or will it just upgrade the original Mac's HD?

    A Samsung 850 EVO 128GB SSD $75 now and makes a huge improvement. But get the 250GB which is $99. 500GB $199
    Wish you asked us first   Awesome prices and performance.
    Output from Etrecheck is an easy "quick check" of what your system is carrying around and what baggage it has.
    Move data to a 'data and media library" drive.
    Use CCC to skip the user data folders except ~/Library and clone to SSD
    And might want to save the installer .ESD package for use as clean installer and to be able to boot from.

    My ISP tells me I need to change the port to send/receive mail, as the current port is going to be disabled for security reasons. But I can't remember my Mail password to add an account. How can I add an account when I don't remember my password? It's been several years.

    your email password is with your ISP so they can help. but if it is saved in the email app you can just change the ports in the preferneces without a password.

  • I have a belkin 7 adapter for additional USB slots for my Mac Pro. It was working well till just recently I am getting a message that says the usb port on the Mac Pro is shutting down due to a very high power drain. Then it shuts the usb port down.

    I have a belkin 7 adapter for additional usb ports for my mac pro. It worked fine without problems till recently when the message regarding usb port drawing too much power and the computer shuts the port on the mac pro down. The strip comes with its own power supply adapter. The attachments are additional hard drives used as backups and independent data. Other than disconnecting it are there any fixes?

    You're getting the message because you're exceeding the available current, probably as a result of bus-powered drives. The power sources for hubs are rather small. Try using drives with their own power supplies.

  • How can a video editor use an NTSC studio monitor on the new iMac without a Firewire 400 port?

    Looking at the new iMacs (hungrily) and wondering how I will be able to continue using my Sony DSR-11 and NTSC monitor in the absence of any Firewire 400 port.  I suppose there may be cables that will allow me to use the Firewire 800 port and am thinking they may be difficult to locate.

    No they're not - they're available from many sources; i.e. I bought a FW 400 > 800 cable when I bought my iMac last August (at an authorized local reseller). Just google Firewire 400 > 800 and you'll get plenty of results. You can also opt for an adapter if you prefer. Both are also available at the Apple store online.

  • Should the fire wire ports always be active

    I have a 17" MBP (core 2 duo late 2007) and a 15" MBP (also core 2 duo late 2007) and when I connect my recently purchased WD 500GB Passport, the drive's light indicates that it is still receiving power from the MBP's after I've shut-down the computers. Mind you, this is with both MBP"s connected to their power supplies. If I disconnect the power supplies the drive goes off, completely. The drive is FW powered and this happens when connected with either FW 400 or FW 800 cables. I'm just wondering if this is usual for this family of MBP's. Have searched the discussions and couldn't find a similar situation.

    Sig...
    I did edit the question, but just as you replied. The drive is FW powered and does not have it's own power supply. You answered my question by confirming that the drive is being powered by the a/c power supply.
    The first time I actually noticed this was in trouble shooting an EyeTV 250 vs and EyeTV 200. The EyeTV 200 has been connected to a Mac Pro for quite some time and when the Mac Pro is shut down, the EyeTV 200 (connected via FW400) goes off, too. But when I connected the EyeTV 200 to my 17" MBP I was concerned to see the indicator light on amber indicating it was still receiving power even though the MBP was shut down.
    Nice to know that this is normal activity. And, since it only happens when connected to the Apple power supply, it won't be a concern for battery life.
    Thanks for the reply.

  • A barcode scanner that was connected directly to the Mac's USB port stopped working as the "USB had too much power drawn", even though it has worked for over a year in that port.  WHen we plugged it into the port on the keyboard, the device works. Why?

    A barcode scanner that was connected directly to the Mac's USB port stopped working as the "USB had too much power drawn", even though it has worked for over a year in that port.  When we plugged it into the port on the keyboard, the device works. Why?  Obviously the device is operational.  Could the USB port have burned out from having too much power drawn?  If so, is it reparable?

    It can't draw "too much" power, it can only draw as much as the USB port is able to provide and no more. IIRC, the keyboard port has a lower power output than the iMac's port.
    That being said, yea, it's possible that the port has failed and it can be replaced or if another port works you can use that one. Although if it is still under warranty or covered by Apple Care, then I would take it to an Apple Store or service provider to get the port repaired.
