How do i reset the pram

I have a macbook pro 2006, ive restarted after  a hard shutdown. (dark screen, but iTunes was still playing and interactive) When i restarted, the Apple logo turned into the "NO" (as in "NO SMOKING") symbol. Will resseting the PRAM help? and how do i do it?

You can reset PRAM using the steps in this Apple article.
You may be better off looking at the steps in this article, which include what to do if you encounter a prohibitory sign on startup.

  • How do I reset the PRAM of my MacBook Pro in OSX Mountain Lion?

    Dear all, I bought a new MacBook Pro 13" (Mid 2012, MacBook Pro 9,2) and upgraded the OS to Mountain Lion. There have been some crashes (apparently related do Chrome), so I wanted to reset the PRAM to "clean up" a bit, but it didn't work. I made sure I followed the standard procedure (as in my old MacBook Pro 15" Late 2008, which was stolen), and held properly the CMD+OPT+P+R combination before getting the grey screen. Just to be sure, I tried shutting down and turning on again and also just restarting my Mac. Neither worked. What may be the problem? Thanks.

    The fact that Apple saw fit to put out a ML-specific PRAM-reset note confirms that the key sequence is unchanged. Yet I've witnessed quite a few instances of people complaining that it did not work on that OS. Will try when I get on my testbench later tonight. But still seems odd to have such a recurrence of the same complaint.

  • Is resetting the PRAM what I need?

    After a power failure, my Power Mac (G4 1.25 GHz Dual Processor) will not go to sleep on command even though the System Preferences are set correctly. Other symptoms of the problem include getting the spinning wheel when I try to modify the System Preferences and it won't recognize my digital camera at ll when I plug it into any USB.
    Is resetting the PRAM what I need to do? Is the only way to do it by going into the actual computer and pressing the button?
    Right now I am in the middle of summer classes for school. Am I risking ANYTHING at all by resetting the PRAM? I CANNOT be without this machine right now.
    Help is much appreciated. Thanks!

    You said correct the "beachball"? What did you mean by that?
    Because you said
    Other symptoms of the problem include getting the spinning wheel when I try to modify the System Preferences
    So, spinning wheel = beachball. Because you had a power failure, there is possibly damage to the hard drive directory, thus the spinning wheels.
    How do I start up from the OS install disk?
    Insert the disc into the optical drive, restart the machine, and hold down the C key on the keyboard while starting. In the window after you select the language, in the Menu Bar/Utilities, open Disk Utility. In Disk Utility, select your start up drive, and then select "Repair Disk". When done, close Disk Utility, and click Restart from the Menu bar. The machine will return to normal boot.
    Do I do that before or after resetting the PMU?
    No particular order, but you could run the Disk Utility first.
    If after running Disk Utility the sleep command still doesn't work, the reset the PMU.

  • HT1712 Resetting the PRAM and the apple screen???

    How long does it take to load back up after resetting the pram? It's been on the gray apple screen for some time now.

    1.) Under Energy Saver: I specified not to ever put my computer to sleep, however, there is a checkbox for putting the hard disks to sleep when possible. What is the difference?
    One's the computer (i.e., the operatinng system stored in memory), the other controls the physical HDs.
    2.) After specifying not to put my computer sleep, I went to the login screen using fast user switching and there is still a sleep button on the login window. I am guessing that this is to put the computer to sleep and not the display.
    Probably. As I stated earlier, I don't use FUS, so don't know its functioning WRT to sleeping. 
    How can I put the display to sleep at the login window? I want to make sure that it at the login window so if I leave the computer I do not need to worry about anyone waking up the display and having access to it.
    AFAIK, you can't. Waking up the display doesn't give access to the computer when it's at the login window. If you could put it into a state wherein you couldn't wake the display, how do you suspect that you'd be able to login yourself?
    This is all I have time for today. If these replies helped/fixed your problem, please mark them appropriately. Good computing.

  • Would resetting the pram cause a forced battery cycle?

    I have a macbook pro that's been plugged in for a few days - I know it was charged.
    Today, I had an unrelated problem and had to call apple support.
    They had me clear some cache folders and reset the p-ram by powering on then hitting command-option-p-r. The macbook was also booted into safe mode several times.
    This evening, I hadn't paid much attention, but I noticed that the battery indicator said it had an hour and a half left to charge, and I see the orange light on. It was never unplugged so I'm curious how the power drained enough to need over 90 minutes of charging time.
    Does anyone know if resetting the pram causes the battery to auto drain/charge/calibrate?
    (the battery has 14 cycles on it, and is less than 3 months old in an i5 15"MBP)

    I must have something going on then.
    I didn't notice it until I reset the pram, but it could have been happening before that.
    I noticed it again today.
    the icon in the menubar showed it was on AC, the adapter light was green.
    I went into the power control panel and it said it was 76% charged.
    I took a few screenshots of the panel over a few minute period and the battery was definitely draining.
    When I disconnected and re-connected the AC Adapter, it then went orange and is now charging.
    Could connecting the ipad, along with a usb keyboard, and a second display, cause the macbook to exceed the 85watt capacity of the power adapter and cause the system to pull from battery?
    Anyhow, I've reset the pram again this morning and also reset the smb for good measure.
    It's charging now, and After it's done I'll leave it on all day so it can calibrate the battery.
    Hopefully a trip to the genius bar will not be necessary as everything else is working flawlessly.

  • How do I reset the e-printer's web embedded server network password?

    I have an HP Photosmart 7520 e-all in one. I use Windows 7.  I could tried to set a password in the EWS network tab. I could not change the user name so it remains "admin". I set the passwork and it seemed ok. But when I tried to log on again, it would not let me in. How do I reset the network password?

    I recommend that you run "Restore Network Defaults" from the front panel and then run the wireless setup wizard again.  This will wipe out all your network settings.

  • Can't Open File Explorer -- How can I reset the Quick Access Toolbar from outside of File Explorer?

    First of all, this is not a virus. This is my a bug within windows explorer itself.
    So, I added the properties button to the QAT, and it displayed it as an expandable menu, like this: ";" but with small arrows like this: ">". didn't want this, I wanted to click on it and immediately display the properties of the file
    to me. So, I hovered over it, right-clicked on "Properties" in this menu and added it to the QAT. Of course, this crashes File Explorer. Now whenever I try and open it, it crashes, so I have to assume that the corrupted button has been saved.
    So, my question is: How do I reset the QAT from OUTSIDE of file explorer? Regedit magic? Any ideas?
    Thanks for stopping by,
    Trolleyman.
    Edit: Just so you know, I can navigate through my systems files using the 7-zip file manager. Phew.

    Thanks from me  too, Niki. This first happened with Windows 8.0 File Manager a week ago,, and despite much research I couldn't  discover the cause so eventually I resorted to restoring  the system drive from backup (luckily I make daily backups, 
    so didn't lose   much  work).
    Without  knowing the cause  a  few days later I again tried to alter  the Quick Access  Toolbar  and the problem reappeared.  Should  I again resort to restoring the entire system drive, the thought horrified me. But
    luckily while doing a bit more research prior to resorting to the same drastic recovery, I cane  across this post  of yours and it worked!
    It doesn't  seem  to be  happening with Office 2007's   or  Wordpad's  Quick Access Toolbar,  so presumably it's a File Explorer bug  (a.k.a. Windows Explorer in Windows 7, of course). Have Microsoft recorded this as
    a  bug -- if not,  why not  -- and when  are they coming up with a fix?

  • ICloud accidentally set-up with erroneous email acct. How do I reset the email originally used to start the Apple ID? I'm stuck in a loop...

    Hi Apple friends! Here's my frustrating situation. When I got the new computer (2012 Macbook Pro), I tried to set up iCloud but accidentally input an erroneous email acct. I cannot access iClod because the email was accidentally input as "[email protected]", not "[email protected]". How do I reset the email originally used to start the Apple ID? I'm stuck in a loop, and not only cannot use iCloud, but I keep getting messages popping up to register my iCloud with a non-existent email...
    Help?
    Sincerely,
    Cole
    [email protected]

    Have you tried to go into System Preferences > iCloud and entering the correct information there? You will first have to "sign out" of the wrong account and then log in with the correct information.
    If that does not work you should direct follow up to the iCloud for Mac forum.
