Mac Pro power off

• Mac Pro power whirring noise

  I have a mac pro 2.1 with a Radeon mac-flashed 7970, witch makes a fairly strong and annoying hum noise. It sounds like a fan bearing or a blade fan of friction or something.

  Initially, I suspected the fan on the graphics card, as the noise got worse when I put the graphics card under load. But stop fans with my finger for a second did not stop the noise.

  I checked all the other fans in the system by turning their speed one by one using a control application third fan, but that doesn't seem to cause noise. When the system was not under tension, speed fans only sounded like a plane taking off, no strange whirring / clicking noises.

  I also followed him Nadim fan when running the reference of sky charts, and none of the fans seems to speed up the noise at startup.

  The noise seems to come from the power supply area. I stick my finger in this fan aswel, but that also did not stop the noise.

  My graphics card is put a lot of stress on the power supply? (seems unlikely, there is not much else in the system.) 128 SSD samsung, and 16 GB of memory, without HARD drives or optical drives.)

  Or maybe just a case of whining reel? I never heard talking about the cases where it is is bad. Sound clearly audible with the mac pro onder my office with the closed side panel. It's about as strong as the average of a mechanical hard drive.

  Someone at - it suggestions on what it might be? Anny information is appreciated!

  UPDATE:

  I've did some more research and tests today, and now I don't know if it's the POWER supply. Further examination, the noise seems to come from the graphics card rather than feeding.

  However, I got the mac pro crash on me earlier and seemed to associate PSU.

  When I tried to run the benchmark in the Valley of launchpad, the mac pro froze for a second about, and then both screens of. Fans and LEDS have remained, and pressing the button did not stop instantly the mac of. After pressing the SPACEBAR and mouse movement a little I tried the button of power again and this time he did close some instantly. After reboot I met the gray screen telling me my computer restarted because of a problem, and I had to almost any key to start.

  Later, I tried to run the benchmark of sky without the installed card via screen sharing, but that did not work. I did trie with another card installed, but who also refused to run the reference point. If unfortunately I have no way to ensure the sound comes from the GUP or POWER supply right now.

  I think that there is still an old mac pro at work that I might be able to test the card Friday, maybe wil give me some guidance on the issue of whether this is in fact my GPU. And if not, I might be able to take the power supply of the mac pro at work and test it in my mac pro.

  But I'm stil torn on the weather to suspect my GPU or PSU. the accident that I got today sounds PSU related to me, but the noise seems to come from the GPU. Anyone have any ideas?

• 2009 mac Pro turns off graphics load.

  Hi all

  My Mac Pro is a 2009 with updated firmware version to support 6-core processors clocked at 2.66 ghz. I have improved graphics, Sapphire HD 7950 / 3 gb (UEFI flashed).

  • While I use the computer for graphics intense situations (IE 3d rendering, games), the computer turns off. In order to get back to the computer, the power cord must be disconnected from the PSU. The computer then turns back on without any problem.
  • The question I have is if there is a power supply problem or not?  I put the GPU in a Windows machine and the graphics card run any graphic intense program with excellence.
  • I have reset the SMC, PRAM and looked at the newspapers, but I can't find a solution. I have currently the power supply of the machine, removed inspect the Board and clean the dust off the camera.

  Please ask for more information, you may know.

  Any help is greatly appreciated!

  Your symptom has been reported by users who have cheated on the power cords to the. Labour intensive overdraws the power available to the map, and overlap the food makes the unstable power and stops at the Mac.

  If your card has one or two 8-pin connectors, you may need more power than can be provided through two cords to the 6-pin.

• Mac Pro turns off and restarts

  I have a Mac Pro 5.1.  I recently installed a USB 3 card with Esata OWC.  Occasionally, the system will restart now.  Usually when I use DaVinci Resolve.  My CPU is not overheating. I have too much on the PCI bus?  It doesn't happen when I take out the card.  Here is the crash report.

  I have a GTX 970 installed with drivers from the web. (I already had an installed 570 and had the same problem)

  I have a card from Blackmagic with SDI IO.

  I have a concert PCI 480 OWC storage.

  Thank you!

• Mac Pro Tower 2012 Unresponsive (Power Light On, red LED turn on)

  Found my Mac Pro 2012 Tower responds more today with the power led and a red led light on the inside of the tower.  The subject of research and could not find anyone who had this exact question (unless I'm missing something) and I also have trouble understanding what LED light and how do I proceed.  Any advice would be greatly appreciated

  

  Remove all external and off devices, disconnect all external cables

  Check your GPU for dust/dirt/creep (where it "fits" of the socket), you can remove it but when undertaking this make sure that you are properly grounded at all times and the components are put in static free containers, then clean the inside of the computer with compressed air ensuring that you damage the connectors not blowing the white point.

  Replace the GPU and follow the instructions to reset the SMC.

  Reset the management system (SCM) controller on your Mac - Apple Support

  See the yellow highlight

  

  Plug directly into a wall outlet connected to the ground not a power strip or battery backup.

  otherwise, to replace the CMOS battery on the logic board, after that leave the device unplugged for 30 minutes or more.

• Power Mac Pro 2010 problems

  So I just bought a Mac Pro 2010 and it ran fine for a day or two and then I noticed that when he falls asleep the light never blinks and turn even a problem.

  If the unit is off, when I first press the button there is a click but the led stays off and nothing happens. I have to hold down the power button until there is another click. When I press the button once again, there is a click and the power of fans on and the machine finally starts. Although the chime time seems very long.

  However, when he goes to sleep, the monitor turns off, I can hear the fans turns off but never flashes as it should the. Subsequently, the computer cannot be awakened from his sleep. This happens if the timer is active, I press the power button or choose to sleep in the menu. I have to hold the power button to turn it off completely, then start it again. Also, when I press the power button to restart the same as above occurs.

  I ran Onyx to flush all caches that I left my SSD (OWC E2) my Mac Pro 2008. I also reset the SMC and the LANDAU and also ran the Apple Hardware test. Nothing has helped and no errors not found in one of these trials. I tried simply have a HARD classic in this drive and removed all my cards accessories but that does not make a difference. Even when I start windows via boot camp the same problem occurs with sleep.

  Any suggestions?

  I had a similar with a 2010 6 core Mac Pro problem except that the Mac I never sleep, so sleep was not involved. An Apple Store Genius diagnosed as a button battery failure and, eventually, the PS. I asked that the two be replaced since the support for that Mac ends. It's worked OK since then and at Pick-up, engineering was agreed that, while the battery needs replacement, the real problem was the PS.

  Until the repair, one of the things that helped aims to let the Mac disconnected from the AC line for about an hour. Immediately after it by plugging in, he would sometimes start and then work.

• Mac Pro randomly turns itself off (again)

  Mac Pro randomly turns off by itself

  I have never got rid of the problem. Even after having replaced my card stock (radeon 5770) display with Asus Strix GTX 980 Ti, used a Corsair CX750 only power supply to power it. Look like anything, it's over heating, im stimulate fans PCI, exhaust and intake to 2500, 2000 and 2000 RPM (respectively). his strong!

  I'm tired of dealing with this old-tech, unreliable, expensive, overrated,... flat of the weight of the aluminum foil, so please find me a real solution/fix! I could easily put together a very decent PC that 'JUST WORKS' from what ive already spent trying to fix it.

  whenever he stops, I hear a click from the PSU (similar to the clicking sound when you press the power button on the front, commissioning). Trying next turn to the after he died, sometimes the power button will not turn on right away. I had to wait at least 10-15 sec to make it work. When it works sometimes stop with click 2 to 5 seconds after pressing the power button. He sometimes dies right after the chime. It starts also through without any problem.

  A few times when sometimes I watch the LED at the front of the Board (opposite the PCI fan) when he died, I see the two top LEDS blink once I hear that click, those who are highlighted red in the picture (not a picture of my Mac real). It also sometimes flashes when I press the button boot but used to power upward after that he died. Please, what that means?

• Mac Pro randomly turns off by itself

  I've had this problem for almost a year now with my mac pro, mid 2013 A1289 and could not find a solution to this day. It randomly and spontaneously turns itself off. The boss is very random. I can turn it back on after a few seconds, but he always die on me shortly after. My warranty period is now over and it does not apply to service nearby (I must send it through flight to the nearest service).

  A few months back I asked my warranty and send it to apple. They said that they replaced the logic board. Many worked for a few weeks but the problem came back (at this time, that my warranty is over). not even the support of apple on the phone is unable to give me a solution. So, I did a lot of research and try to fix it myself with the help of Heads of the local computer. I suspected a overheating, but the problem came even when I turn it on for the first time in 2 days. I got a 2kva voltage stabilizer and APC back ups pro 1000, did not help. I got all my RAMS controlled, are all 100% working. I removed a few RAMS and switched around to see if there is problem with the slot machines, has not worked. I bought an SSD, deleted all my old HDD, installed a new OS, still the same problem. The only thing that I have not checked and now my only suspect because of the problem is the power supply.

  Sorry for making it very long but I wanted to be as detailed as possible. I lost a lot of time, thought and money. And it's hard not to feel deflated. Please, if there is someone out there who can find a solution, it would mean a lot.

  Note the next closing time. After the reboot, open the Console app in Finder > Applications > utilities and look for entries of the log at the time of the shutdow. Suspicious message here.

  Look before the entry titled BOOT_TIME because this indicates that the beginning of a startup.

  Also, what Mac do you have? A1289 indicates your desktop Mac Pro Tower silver and covers many years. The last silver Mac Pro Tower has mid-2012. I end 2013 Apple introduced the Mac Pro black trash

• UPS: turn off at Mac Pro every night

  I just bought a new power supply (UPS) uninterrupted and it comes with the option to transform the every night to save energy (after I stop the desk top Mac Pro).

  I searched the internet and Apple support communities and apparently there is no big advantage or disadvantage to stop the Mac Pro every night.  It does not harm the desk top, it allows to save some energy, and it makes it safe from hackers while I'm asleep.

  I can't find anything that tells me if there is a problem with completely set turned off power every night well.  Anyone know of any reason not to use "SHUT DOWN" and then turn off the UPS?  I guess the only difference it makes to the desk top Mac Pro is that it uses a battery to keep the current date and time.

  An overview of everything that will keep my Mac Pro (mid 2010) humming is greatly appreciated.

  It uses the battery to keep the current date and time.

  ... and to remember some system settings that must be available at the beginning of the start-up procedure, such as "where is the boot drive.

  If your Mac does not start, the battery is a Lithium long term non-powered cells of room behind the graphics card slot. It should measure about 3 Volts in your hand to be useful. BR2032 is what apple installed, CR2032 will work in a pinch. They are used in the door openers garage and car-door-keys.

• My Mac Pro 2009 gives me only a power button blinks when I try to turn it on.

  My Mac Pro 2009 gives me only a power button blinks when I try to turn it on. External drives turns on but not the computer or monitor. I tried holding down the power button to restart but I still get only a power button blinking and no departures. It is running IOS 10.8.5 and I use it mainly for recording and mixing of music. I use Digital Performer and, sometimes, ProTools. Nothing new has been installed recently.

  fans on, power button flashing says "not enough RAM that works correctly for starting up".

• When using OS 10.11.4 after using Safari for a few minutes, the system freezes, the only way to UN - freeze is to close the system with the power switch on my Mac Pro early 2008. Any ideas?

  When you use Safari on my system Mac Pro 8 core early 2008 if will freeze with no other way to free it up it's close with the power button.  Any ideas?

  Once you can restart go immediately to disk utilities and run repair disk permissions.

  When is check your Safari to make sure you have the version appropriate for your machine.
