La Cie Mini external HD suddenly won't power up

I've had a La Cie Mini HD connected to my iMac G5 for over a year, and I just noticed today that it won't power up at all. I've always used the built-in USB port, and the only other device I've ever connected that way is my iSight camera. (I noticed the La Cie went a little wonky whenever the camera was connected, so I got in the habit of shutting off the La Cie whenever I did a video chat.) I've just tested the iSight on both built-in USB ports and the camera works fine, so it doesn't seem to be a problem with the USB port. I thought it might be related to recent software updates (I did the 10.5.8 update and whatever else has come along in the past week), so I repaired disk permissions, but the HD still won't power up. Would appreciate any advice!

Hello katydid1969
(1) Can you take another look at your system and perhaps correct your problem statement?
(2) *Only built-in iSights are connected via USB*, but built-in iSights cannot be "connected" and disconnected.  If your camera is an external iSight, it connects via Firewire rather than USB.
If you are having problems with Firewire iSight when connected at the same time as your Firewire LaCie drives, yours is a common problem that has existed as long as iSight. I believe that the problem relates to the differences in data stream timing between multiple connected Firewire devices.
Although adding additional Firewire cards to tower Macs (iMacs do not have this expansion capability) is reported to work for some users, the *only certain work-around that I have ever found is to disconnect other Firewire devices when using your iSight and turn off or disconnect your iSight when using other Firewire devices*.
For more info, see this linked page regarding Possible Hardware or Software Conflicts with iSight or iChat.
If your LaCie drive is connected via USB, it does NOT likely conflict with your external iSight (or vice-versa.) In that case, you will need to troubleshoot the drive, cables, ports or other USB possibilities.
(3) If your problem does NOT relate to Firewire devices, we will try to offer other suggestions in response to the details in your reply.

  • LaCie External Harddrive suddenly won't mount via Firewire 400 or 800

    My LaCie External d2 Quadra suddenly won't mount via Firewire 400 or 800, but will mount via USB 2.0.
    I have:
    Tested the harddrive on another computer and it works fine via firewire.
    Shut down and re-boot. It had no effect.
    Updated all software.
    Note: My MBP will not boot if the Firewire 800 cable is connected.

    I've had a whole heap of strife with my two macally enclosures over FW. I've only got them working twice together, regardless of jumper settings on the harddrives. I can plug either in fine, but if I use both together, my mac shuts down and refuses to boot. One drive is bus powered, the other is powered via the mains
    I wish you luck

  • G4 mini Random Shutdown; Now Won't Power On, Power Supply Problem?

    Twice now, my G4 mini has simply turned off randomly. The first time, it eventually restarted, and all was good until today, when it did it again. This time, it simply won't power on, much less boot. I wanted to run this by someone else (no Mac people here but me) before I bought a second power supply.
    What I've noticed:
    *If I plug a cold power supply into the wall, and then into the mini, the mini lights up for maybe half a second, then turns off again.
    *Then, leaving mini plugged in to the PS, if I uplug the PS from the wall, wait ~3-5 minutes, plug it back in, the mini will light up for 1/2 second again.
    *If I then unplug the PS from the mini (but leaving the PS plugged into the PS), wait ~3-5 min again, then plug the PS back into the mini, nothing happens. No lights, fireworks, nada.
    I have repeated every possible combination of plugged/unplugged mini/PS in several outlets throughout my building. It seems that if I have a "hot" PS the mini will not light up no matter what. If the PS is "cold", and has sat for a few minutes, the machine will try to boot.
    All I can think is that something in the mini is tripping a safety on the PS, or the PS is just tripping on its own.
    Bad PS?

    It's possible the previous power supply failed in a way that caused damage to the system, or of course for another fault to have developed with these symptoms.
    It's interesting that it worked, apparently properly, because that tends to suggest the fault is something new, or that you have power issues of another kind external to the Mac.
    I would suggest you try and reset the PMU since this controls the power management functions of the system.
    - Unplug all cables from the computer, including the power cord.
    - Wait 10 seconds.
    - Plug in the power cord while simultaneously pressing and holding the power button on the back of the computer.
    - Let go of the power button.
    - Press the power button once more to start up your Mac mini.
    This may not help much, but it's well worth trying.

  • Old Reliable G4 mirror suddenly won't power up....YIKES!!

    my trusty, G4 MDD, almost 4 years old now, never had problems, all of sudden will not power on at all when the power button is switched on....I tried resetting the button on the motherboard next to the battery (PMU?) and still nothing...
    from my research, it sounds like a power supply, but is there any thing I can do at this point to at least try to get this thing powered up?
    I'm not really anywhere near a mac tech, but I do have other issues
    a) in case it is a power supply and it needs to be replaced, will it affect the files on my boot drive?
    b) I do have a spare 733 Quicksilver...I had been running a separate audio drive that I'm sure I can probably install on the Quicksilver to at least retrieve my audio files, but if I remove the boot drive on the 1.25 mirror door, can that simply be installed on the Quicksilver also to retrieve some other very important stuff...
    HELP!

    so regardless of whether it's the boot drive or the supplemental drive, it doesn't matter?
    Correct. Either one can be installed in an enclosure and will be seen as an external.
    now, if I install the old boot drive from the MDD into a firewire enclosure, can I plug that drive into my spare Quicksilver and boot from that? if so, how do I do that? (provided the drive isn't messed up)
    Go ahead and try it. Connect the external device to to the QS and check System Preferences. If it is bootable, System Preferences / Startup Disk will list it. At that point you can select it as your startup drive and restart.
    By the way, I suspect you already know this, the power supplies of the QS and the MDD are not interchangeable.

  • External hard drive won't power back up when iMac wakes from sleep

    I have the external hard drive connected via USB. I always put my iMac to sleep before going to bed and I wake it up when I come home from work. Except that when I do, the external hard drive doesn't power up. It still shows in Finder, but clicking on it's folders just opens them up as if they were empty. There's no access noise and the drive can't be ejected.I have to switch it's power off and turn it back on for it to spin back up.
    At first I thought it was because I had Energy Saver set to power down the drives whenever possible, which works just fine when it's on, the drive powers on and off as needed just as long as the iMac doesn't go to sleep. I turned it off just to make sure and it made no difference. As soon as the iMac goes to sleep and the drives powers down, it will not come back on without a power cycle once the iMac wakes.
    I've used this drive in an old Macbook for years without having this problem. The only difference is that the Macbook was on 10.6.8. I was thinking about buying a 4 bay USB enclosure and filling it up with hard drives, but I'm not about to do that if every time I put the iMac to sleep, the whole thing will not power back on without a power cycle.
    Any help would be much appreciated.

    Not sure if you managed to get this issue resolved yet Marcus, but I too have a similar problem:
    Currently I'm upgrading from Leopard to Lion (via Snow Leopard) on both an iMac and MacBook Pro (both Intel), but before I proceed with the OSX upgrade I wanted to back everything up. Thus far I have partitioned an external firewire drive (G Drive - one that is bootable), and cloned each machine using Carbon Copy Cloner to it's own partition (both GUID). There is plenty of space left over on each partition.
    The issue - I can boot the OS X from the external drive on the MacBook Pro but not on the iMac.
    When I restart and hold down Option on the iMac the only drive that appears is the HDD, not the other two selectable drives that are visible if I boot up on the MacBook Pro. On the iMac in System Prefs > Startup Disc I can see all 3 drives but when I select it and restart, the machine freezes on the grey loading screen and goes no further.
    Not that it should make a difference, but there is a 3rd partition on the external drive that is currently empty (for extra storage).
    Any help is greatly appreciated - I can't find any relevant answers elsewhere. Thanks,
    Dan

  • HT3964 My iMac is approx 3 years old. It suddenly won't power up. It was plugged in through a power surge preventer but there seems now to be no life at all. The fuse in the plug is fine.

    iMac that won't power on, any advice please?

    If there are no sounds or video at all it seems the power supply is dead. Take the machine in for service at your local Apple Store or AASP. Then when it's repaired connect the machine to  a uninterruptible power supply, you can purchase a good quality one for less than $100 at your local office supply store.

  • TS1365 MacBook Pro 2012 suddenly won't power up

    My mid 2012 MacBook Pro just developed a strange power problem, won't power up at all. None of TS1365 above helps. The magsafe adaptor works fine on another Macbook. On the new MBP the green light slowly dims, and there are no lights showing at all for the battery when its button is depressed. Is this an Apple Store visit required?

    8. If you are still unable to start up your computer after trying each of these steps, schedule a service appointment with an Apple Retail Store or an Apple Authorized Service Provider. If you plan to visit an Apple Retail store, make a reservation at the Genius Bar using http://www.apple.com/retail/geniusbar/ (available in some countries only).

  • G-tech G-drive mini external h.d. won't turn on

    I have a new G-Tech G-Drive Mini (500 GB) external hard drive which was just fine the first time I had it connected to my iMac. I got it all set up, backed up some files, put it away and that was that.
    Today I got it out, turned the power switch to ON but nothing happened. It won't turn ON. Connected to the computer by an 800-firewire or not, it won't turn ON. No green light, no nothing.
    I realize this isn't a Mac question per se, but I bought it at an Apple Store (it's now past the return date) and it's the weekend and G-Tech is closed. And I am VERY frustrated.
    Any advice?

  • External HD suddenly won't show up in finder

    I have an Iomega external HD that I've had connected to my iMac for several years now. All of a sudden, it has disappeared from the finder. System Report shows it is connected, but neither rebooting the computer, the HD nor both has caused it to reappear. It contains my iTunes library and iTunes can't find it either. I connected it to my wife's iMac, also running mountain lion, with the same results. I've connected it via firewire and USB. My Focusrite audio/midi interface is connected to my iMac via this HD and shows up, but doesn't work.
    I've tried disk utility. It shows, but under the name of the HD, the name I gave it, "music", is grayed out and the Mount Point is "not mounted". Verify Disk says it is okay. Trying to mount it returns the message:
    The disk “Music ” could not be mounted.
    Try running First Aid on the disk and then retry mounting.
    Running First Aid again doesn't change anything. Any ideas? If the disk is dead, can I get my data from it to another disk?

    Nothing has ever been overclocked on this system.
    Everything is plugged into a Belkin Surgemaster powerbar.
    I haven't mentioned the power supply. I'll get to that. I have been using an ANTEC NEOPOWER 480W POWER SUPPLY (ATX12V  DUAL 12V RAILS ACTIVE PFC W/ DETACHABLE OUTPUT CABLES) for about a year on this system without
    any issues. One morning, I wake up, hit the power button on my coolermaster case, and nothing happens.
    CPU fan won't even spin. Nothing happens.
    O.k., blown power supply, I think . . . .
    So I take out my Antec and put it in another system. That system turns on
    without any problems.
    Hmm . . .
    I come here, and I read posts about
    potential compatibility issues with Antec power supplies. But if it's a compatibility
    issue why was my system working for about a year?
    O.k., fine. I'll buy a Enermax 535W EG565P-VE FMA 24P (115/230 VAC) power supply.
    I just plug it into the mainboard (nothing else). Hit the power button . . .
    The CPU fan spins for half a second, and then nothing.
    Did my motherboard just suddenly die for no reason?
    Any suggestions?

    Pull the AC plug from PSU and set cmos in clear position with battery removed for atlest 20 minutes perhaps longer .
    Then try to post the system barebone .
    Just cpu,1 pcs memory in slot 1 , gfx card , and keyboard in PS2.
    No usb devices at all including card reader and no pci cards harddisks or cdoms/dvd/floppy.
    It could also be caused by a short or a malfunctioning fan connected to mobo.
    Try to disconnect all case fans from mobo headers if you have any connected to additional fan holders.
    The chipset fan can also be disconnected momentarily just to see if it posts.
    If none of this helps , replace cmos battery and try again .

  • Dead iMac G3 suddenly won't power on. PRAM battery or Power Supply?

    iMac G3 350 slot load USB only running 10.4.11
    i love this little guy.
    it's been running almost non stop for a few years as a file server... only restarted maybe a dozen times during that period. i can't remember ever shutting it down.
    i had to move it recently. might have been unplugged from a wall socket for a minute or so. plugged it back in but left it powered off for a few days.
    went to turn it on recently and nothing. not a chime, not a light, not a click or hard drive spin-up. zero. pushed the PMU reset button once. still nothing. i've taken the PRAM battery out for now.
    my question is this: is it possible the power supply is dead and a PRAM battery will not fix the iMac? is there any way to tell before spending money on a new battery i may not need?
    thanks!

    Hello Nicholas,
    I recently retired my hard working 350 slot so I know how great the computer can be.
    Unplugging for a moment should not have affected the battery.
    I would respectfully suggest you start with the simple things such as:
    1. - Make certain the power source is not on a switch and that it is good
    2. - Be certain the power chord is fully seated in the back of the computer and wall socket.
    3. - If trying to start from the keyboard button, try using the button on the face of the computer
    perhaps the keyboard is not fully plugged into the usb port.
    I always like to start with the simple things when I have a problem.
    Now that the battery is removed it could cause a bit of a problem. I think I would install the battery
    and check the above mentioned ideas. If still no power, then I would replace the battery.
    It doesn;t seem logical that the power supply would just go as a result of the board.
    I would try to get the computer up and running.
    One last tip.......when my slot load was starting to go it acted odd. I would let the computer sit for a day or two and it would then start. It was irratic at best but the old computer allowed me a few last
    boots so that I could back up to my external.
    It is a great computer and sounds like it served you well it deserves a few chances.
    I hope you replace the battery, plug and it re-starts. Keep it plugged in once the battery is replaced/returned .....Best of Luck Jim

  • MacBook Pro (late 2011) suddenly won't power up

    Was working with my MacBook Pro this evening, initially on battery power. Switched to AC when the battery was at 60%. An hour later it was nearly fully charged and I closed the laptop (without shutting down) and took it with me to a restaurant. Got back to work, opened the MBP up and...no power. MagSafe light flickers faintly; no battery indicators light when I hit the battery strength button. Tried an SMC reset and a PRAM reset to no avail. All this while I'm in a foreign country doing a project with a tight deadline.
    I'm going to attempt to see an Apple reseller in the morning, but does anyone have further troubleshooting or diagnostic suggestions? Thanks.

    The Mac Pro logic board includes a set of LEDs to help troubleshoot the
    computer. The LEDs are located toward the rear of the logic board, under the memory cage, next
    to PCI card slot 1. You can view these LEDs by removing the computer’s side access panel and
    looking through the memory cage to the logic board below. LEDs 2, 3, 4, and 5 are normally off
    and will automatically illuminate if an error occurs. To read LEDs 1, 6, 7, and 8, you must press the

    All movies (YouTube, Vimeo, my own on internal or external drive) suddenly won't play on iMac.  Just started happening 3 days ago.

    They just didn't play from browsers, my own mp4's,  or .mov files, iMovie wouldn't work either; but solved it today by simply re-loading OS 10.9.2.   Everything works fine now.

  • Pavilion dv6 laptop - won't power up, and other weirdness

    This laptop (model dv6-3143us) was working fine... and now suddenly won't power on. However, with the (fully charged) battery inserted, the LCD screen is on - blank, but very definitely on, even though the rest of the computer is not. 
    I removed the battery, tried a hard reset, swapped the AC adapter with a known good one. The tiny LED next to the power input jack does not come on. Pressing the power button - nothing happens. The AC adapter's LED is lit, and it will power another identical laptop.
    The LCD coming on part is what really confuses me. Maybe a short somewhere? Ideas appreciated!

    Jon-o-groats,
    Sorry to hear that, if you decide to go ahead and get the computer repaired, here is the service and maintenance guide for your computer. On page 91 it shows you a list of the motherboards that should work for this particular computer, next to each board there is a part number that will allow you to search for online for comparisons and prices.
