Can I reset PRAM or NVRAM in a MacPro?

Hi all,
I'm on my second MacPro - Apple changed out the last one because of fan & bluetooth issues - and since the latest 10.4.8 update my fan is a bit louder than before so I thought I'd try the above as it worked on G5 machines. I know this has EFI or something wich is different to the G5s so any ideas?
Also, where is the SMU reset button; is it the one in the RAM bay above the higher board or is there another?
I'd like to add, this machine is giving a constant Airport connection of 3mb - 4mb + [on a 4.5mb link] whereas my previous one was lucky to give me 500k so it looks like the wires are being connected properly now?
Thanks in advance to all :0)

Yes you can reset PRAM and NVRAM…
http://docs.info.apple.com/article.html?artnum=2238
… in a Mac Pro just like any other Mac.
As for the SMC reset button. Apparently it's placed…
"Press the SMC_RST switch that is located slightly below and to the right of the row of diagnostic LEDs. Use a non-metallic, non-conductive object, such as a wooden pencil."

  • I reset PRAM and NVRAM and PMU screen on ibook dark can't see

    Hello. My g3 ibook screen was changing from darker to okay. I read the forums about reseting pram and nvram and pmu. So, I reset the PRAM and NVRAM, scren went completely dark. It still would chime and boot up. Witha flashlight you could see desktop. So, I reset PMU, now no chime and still desktop is dark. What happened? I don't have a cable yet to hook it up to an external monitor. I ordered one on eBay, should have this week. What did I do to the ibook? More importantly what can I do to make it work again.

    Does adjusting the angle of the display make a difference? (A little forward or a little back?)
    Here is the link to Apple's Knowledge Base article on troubleshooting portables that won't turn on or start up:

    Maybe something there will help.

  • Resetting PRAM and NVRAM bring Bluetooth back

    My MBP Bluetooth menu lost somehow and could not connect to
    "Apple Wireless Keyboard" and "Microsoft Bluetooth mouse",
    the following steps seemed working:
    1. Resetting PRAM and NVRAM:
    http://support.apple.com/kb/HT1379
    note you have to "Hold the keys down until the computer restarts and you hear the startup sound twice".
    2. Connecting to "Apple Wireless Keyboard":
    http://support.apple.com/kb/ht1809
    ** "First unpair the keyboard If the unpaired Mac is within 33 feet
    (10 meters) of the computer your keyboard is currently paired with"**
    3. Connecting to "Microsoft Bluetooth mouse"
    http://www.microsoft.com/hardware/mouseandkeyboard/features/bluetoothhow_toconnect.mspx
    note you have to hold the connect button on the bottom of the mouse:)

    Most likely an issue with the system management controller interacting with the bluetooth host controller, it can be reset by doing 1 of these three depending on your situation:
    If you have a desktop computer: Unplug it from the outlet and anything plugged into the firewire/usb ports, leave it that way for 45 seconds minimum check it again and see if it mounts in disk utility
    If you have a laptop do one of these two steps and post back if it mounts:
    Removable battery: Remove battery, disconnect charger(power adapter), hold down power button for 5 seconds, put back in battery should resolve
    Embedded (non removable) battery: plug in the power adapter/charger, turn off computer, hold down on the LEFT side of the keyboard Shift-Control-Option. While your holding all of these press the power button once, let go of just the power button. Two seconds or so later let go of the rest of the buttons, you'll know this step was successful if it didn't turn on.

  • IMac screen is black, Resetting PRAM and NVRAM did not solve

    Hi
    My iMac screen just went black. I tried
    Resetting PRAM and NVRAM and the SMC but it didn't help.
    The computer starts up and shows the gray screen, but within a second it just turns black.
    I need help please!
    Thanks

    You can try to reset the SMC by unplugging the power cord from the back of the iMac for 1 minute. You can also try to start up to the install DVD by holding command+C on startup with the disc in the iMac. If it does the same thing after the SMC reset and when you try to start up to the install DVD I would take it to an Apple Store or Apple Authorized Service Provider for hardware tests.

  • Will resetting pram and nvram on Mac osx help download problemss?

    I have a new imac which I play Sims 3 on.  The game plays really well but I am unable to download content from the official EA exchange website.  When I try to do this by clicking on the link everything freezes and I get the spinning rainbow curser.
    To troubleshoot this I have uninstalled, reinstalled and added latest patch.  I have tried safari and firefox browsers.
    A person from EA help said to reset the PRAM and NVRAM.  I have been told how to do this, but am a bit worried as it sounds a bit extreme?  The imac is only 3 days old and I don't want to break anything

    Phew problem solved!  Instead of using Safari I had to use Firefox.  But then I had to select some boxes...I did not do that the other times!
    If anyone else has that problem the answer is
    Open firefox
    -firefox
    -preferences
    -Applications
    Then scroll down to Sims3 and select Use The Sims3 (default)
    I have no idea what it all means but it works.

  • Resetting PRAM and NVRAM

    Is it ok to have a PRAM and NVRAM reset two times a week?

    No, it doesn't do any good unless you're having a problem that those procedures fix.
    Edit: I've never reset PRAM or SMC/NVRAM on 4 out of 5 macs.

    Try a SMC reset and see if it will charge.

    You may want to check the info below before, then after the SMC reset.
    You can click on the Apple logo in the menu bar holding the option key and click on system information, select power in the left side bar  under the Battery Info and check the battery condition and if it is charging, and other stats. Then pull the charger and see what it says.

  • No Video, Can't Reset PRAM, boot sound/led light/fans all okay - logic brd?

    Hello All,
    I'm trying to find out what's wrong with my G5 Tower. When I push the power button on, the led lights up as usual. The fans spin, hard drives/optical drives spin, everything appears normal. However, I get no video. I've tried reseating the video card, disconnecting power for 10 mins, and reseting the pmu on the logicboard.
    I believe the problem is either the logicboard or the video card. I tried resetting the PRAM multiple times, but it doesn't work. It's as if I'm not holding down the buttons on the keyboard, or the keyboard is not responding. I've tried a couple different keyboards.
    Does this seem like a logicboard thing since I can't reset the PRAM?
    Any help or suggestions very welcome!
    Thanks!

    Hello Again! Check the voltage of the battery to see if it's 3.6 volts. A weak battery can keep it from starting. I have seen video cards go bad. Have you tried an alternate (if one) slot for the video card? Tom

  • Resetting PRAM and NVRAM Revert System to 9400m?

    I just noticed this and was wondering if it was a common occurrence. If I have my MBP set to use the 9600m GT and I decide to reset the PRAM/NVRAM, will the computer automatically revert to the 9400m after such reset. I just noticed that my graphics settings changed by itself and could only draw up the PRAM/NVRAM reset as the cause. Is this the case? Thanks!

    Yes it is

  • Can't reset PRAM on 2008 8-Core Mac Pro

    My Mac Pro has been behaving weirdly for a while, and since it's been years, I figured I'd zap its PRAM. But it doesn't work.
    I have an Apple wired keyboard, connected directly to the Mac Pro (no USB hub). But when I restart the Mac holding down cmd-opt-P-R, it's ignored -- it goes straight to the desktop as usual. No cycling of boot-up and no multiple chimes.
    Any ideas why?
    (Yes, definitely command and not control. I'm a Mac vet.)

    Hi JAso, no worries. glad to help. Yes try and crank up your MP 2008 on another file system with OSX on it. Keep that OSX pure.. no unneeded apps.. duct the basic OS and any S?W updates / maintenance - repair the disk permissions and reboot of the new OSX.. - make user/pwd  jaso .. etc.. be as quick and lean as you need. Keep as maintenance starter
    What to look for from restart of new FS ( memory stuck  / FW disk etc):
    spritely start up and login.. just like out of the box
    fast login to new clean user/
    restart it a few times to resolve any "struth that fast!" anomalies...
    What to do next if the former is true...:
    well it's likely your MP's h/w is healthy and as reliable as ever and..
    main file system is a bit buggered and can USUALLY be corrected... (but not always)
    the OSX OR the localised goodies in ~/ that you use and a bit crook (r.s.), stale, plotted, bloated and possibly corrupt.
    Else.. hmm the MP might need some surgery. The main file system's storage hardware (Macintish HD et al) might be slightly crook.
    Anyway all of the is and the really cool things you can do to fix the S/W structures to make you mc kick along is easy to do.
    AND.. read this with vigour and enthusiasm..
    contrary to many of the sheepish and parroted posts in these forums there is usually NO NEED TO REINSTALL the OS. to fix these slowdown things!
    use available tools  to perform basic clean up and some surgery
    one or two commercial ISV software.apps you MIGHT optionally purchase to perform filesystem tune ups beyond what OSX offers.
    Anyway mate.. see if you can sort out a small OSX standalone system on an external spinning disk .. preferably SATA, eSATA, FW800 .. rear of that .
    Oh and is you have a spare FW MAC,, fire up the MP2008 in TARGET MODE (hold 'T' key at startup), slip in a FW 800  cable between each and off you go.. You can checkout the MP's file systems from other Mac.
    More Opinion: ALSo Recovery Partition if you have it. Often there's can be unavailable or as corrupt.
    THere's tonnes of ways to check this out...WITHOUT whacking th existing OS... thats a subsequent resort.
    Post your results for others to see.

  • Cant reset PRAM and NVRAM!!!

    hi i having trouble with my macbook, and i need to reset the Pram but i cant i have been trying for more than 10 times and i cant reset the pram with cmd+alt+p+r. is there any other way to reset the pram,, maybe its cause i put a password on openfirmware?, i want to the rid of the password too!!! is the anyway to get rid of the password?
    i dont have any Os installed on my MAc so icant download any app

    Greetings,
    Read this article on the Open Firmware password: http://support.apple.com/kb/HT1352
    Enabling the password disables a variety of startup keys including the PRAM.
    Follow the section of the article for activating the Firmware password and in step 5 remove the check mark for "Require password...".  This will disable the firmware password allowing you access to the startup key combinations listed in the article.
    Cheers!

  • Can't reset PRAM - Horizontal lines on Display

    I've been having some erratic behavior on my iMac, possibly since the last software update. I'm seeing some horizontal lines on the displays intermittently in a seemingly random fashion. I wanted to try resetting the PRAM and I tried holding Command + Option + P + R down while booting the machine multiple times and it won't reset. Any suggesting? Is there an alternative method or resetting the PRAM on on Intel Mac. I have a wired Apple keyboard.

    Just to verify your attempt at resetting the P-RAM: http://support.apple.com/kb/HT1379?viewlocale=en_US
    Do you hear the boot chime or does it just boot up normally even though you are holding down the keys? It is possible that the keyboard is not being activated immediately by the hardware controller. There have been some reports of this happening with the new Aluminum keyboards. If you have an older Apple USB keyboard that you could borrow just long enough to reset the P-RAM that should work. Otherwise you might try resetting the SMC: http://support.apple.com/kb/HT1543?viewlocale=en_US

  • Resetting PRAM, Network Preferences

    Hello,
    I have a PB G4, 1.25 GHz, OSX 10.4.11
    -Trying to reset PRAM and NVRAM as described in Article HT1379,
    the Harddisk runs, but the display remains dark and nothing happens.
    - Opening the Network Preferences, a pop-up window appears:
    "Your network setting have been changed by another application".
    It's a little bit tricky to get back to a "normal" window then.
    What can I do to resolve these two problems???
    Thanks in advance

  • Resetting PRAM Messed Up My Mac!! :(

    Noticed a couple of problem's after resetting mu PRAM. After I reset my PRAM my subwoofer no longer works as it did before I reset my PRAM and when I power up my Mac Pro Tower it stars and then when it's starting it chimes and does another "restart".
    Before I reset my PRAM it would just start up once and not restart. What's going On? And what is NVAM? Do I need to reset that too?
    Please help.

    Ok, so resetting PRAM and NVRAM are done at the same time, so in that case I did it and that's when this problem started. Loss of Subwoofer and Computer chime and restart after powering upp the computer.
    Anyone got any idea what's going on here? This is getting frustrating!
