Mac Pro :: Try To Boot It Back Up, It Comes On And Chimes And Hear The HDD Spin Up?
Jun 16, 2009
I'm having a worrisome problem with my MDD dual 1ghz g4. It will sometimes turn off when in sleep mode. When I try to boot it back up, it comes on and chimes and I can hear the HDD spin up, but then it will just turn off. Usually after about 3 or 4 attempts it will boot up just fine.I thought it might be the battery on the logic board, since the clock would re-set every time the machine was powered down, so I replaced it. That fixed the clock issue, but the machine is still turning off and taking several attempts to start back up.
I have no idea what is causing this. One thing I do know is that this house is pretty old and the wiring seems iffy. I have a battery backup on another machine and sometimes it will start beeping like it's lost power, but it's still plugged in and the light indicating that it's receiving power is on, so I think sometimes the power from the wall fluctuates. This might explain the MDD spontaneously shutting off, but does it explain the difficulty restarting?BTW, I searched the forums to see if anyone had asked this question, but found no threads,

I have a second hand 12" PowerBook G4 that sometimes will not boot. It will sometimes chime and the LCD will stay black. Like I said this does not always happen. I have already tried to reset the PRAM and PMU and this does not seem to have any bearing on the machine.

Last night, after a few hours of using it (from 100% to about 8%), I tried turning off the computer for the night. After the dock and everything else disappeared, I got a spinning beach ball of death. The computer wouldn't turn off for at least 15 minutes. I had to do press the power button for 5 seconds to get it to turn off. I restarted it this morning and it seems to be working fine for now, but I'm scared of turning it off again.
Here's what I know: while the beach ball was happening, my wallpaper was still on the screen, the trackpad worked, but the brightness and volumes didn't, so I'm guessing I was logged out and no files were corrupted.
During the beach ball, the hard drive would slow down, then spin back up. I waited until it had slowed down a bit to do the hard reboot. I have to say that I reset the PRAM yesterday morning, thinking it might be good because I changed the hard drive to the Momentus XT last week and I read that you should reset it when you change hardware inside the machine. I did that before the crash, so when it crashed, it was the first time I tried to turn the machine off since resetting the PRAM, could that matter?
This morning, I went to disk utility and repaired permissions, there were probably a few hundred bad permissions, but Mac OS fixed them. I also tried verification, but it was alright. I then ran the daily, weekly and monthly tasks and everything went great.
What should I do? I already have a charger problem and a �screen is too blue whichever way I set it� problem. Do I have a lemon here?

It's my understanding that the start up chime you get when you start up on any Mac,c an NOT be changed because that sound is in the firmware. Cool.
That being said, is there anyway to add/hear your own custom sound clip AFTER that?
Does any one know how to do it?

Ok so my macbook just froze up on me, and I shut it off manually. However, when I tried to start it back up it would not boot up. I am just receiving a message telling me " You need to restart your computer. Hold down the Power button for several seconds or press the Restart button. "I did what the message told me to do, and when I started the computer back up I just received the same exact message. I tried to take the battery out and hold down the power button to discharge any electricity in the laptop, and then I plugged in the power cable with the battery still out, and I am still receiving the same error message.I have tried the same process a couple of times and put the battery back in and then I decided to try inserting the Installation DVD, and it did nothing different then what I have been getting.

Sometimes my Imac (mid 2011) starts chiming; this can happen on waking up, or while it is sending email; I haven't spotted a pattern yet. It has been happening more often lately.

I have a 13" MBP which I bought a few months ago. Everything works fine, battery life is wonderful, it couldn't be better. A few weeks ago it began "chiming" about every 20 minutes. One single tone - not a beep - more like the chime from a tuning fork. No message is displayed on the screen when it occurs. Sometimes it happens when I'm using the machine (normally web browsing). Other times it chimes when the screen is closed down and I'm re-charging. It doesn't happen when I start up. I've even checked to make sure there are no other browsing screens opened in the background.

I am trying to figure out why an iMAC does not boot properly. Model ECM 2133 Memory:1GB (only 1 module in one of the 2 available slots). Everytime I push the power button I only hear the chime sound and that's it. You can hear the HDD spinning but the screen is always black. I already did the SMU and PRAM reset and nothing changes.Keyboard is still unresponsive and the screen is black. Mouse light is responsive. I pluged the keyboard on another computer and it works fine. Sorry if I'm not doing something right but I am a newbie with MAC's

I recently got a cheap used 12 1.33 PB, that has worked great for a couple of months.Yesterday the PB shut off totally while in sleep mode. I couldn't power it back up at first, but was able to after I reset the PMU, and plugged the power cord in. The computer worked fine after that for the rest of the day.This morning, I noticed the PB shut off again during sleep mode. But this time, I can no longer boot it up. The PB chimes, but then nothing comes onscreen, and there's no hard drive activity (so I'm pretty sure its not the screen.)

When I restart my Mac it chimes several times as if the PRAM is being reset. Could this be telling me my internal battery is dead?

I'm running OS X 10.6.8 on a 2.7 GHz i7 Macbook Pro with a 250Gb Apple SSD TS256C. Since last Autumn, after a problem that saw the SSD replaced by Apple and me needing to migrate my profile across from an older Macbook, every time the system shuts down it forgets my sound settings. So no matter how I set the sound before powering down it always chimes on start up. It's entirely possible that this may be a problem from the migration, but I don't know how to rectify the issue.

Current Problem: When I try and partition it with boot camp assistant, it just freezes my laptop. I have a mac book and the OS X. Boot camp should be with the OS X, but it isn't there. I figure I must have deleted it at 1 point but how do I get it back? I have already tried entering in disc 1, but it wasn't there under applications. Do i have to reinstall OS X all together? Last time i tried that it said the disc was unreadable. I'm a computer idiot so give me all the necessary info and any links if they are needed.

I inherited a PowerBook G4, 10.3.9, from the previous person in this job. I set up my own user account and log-in. Then foolishly I decided to rename the little house icon folder from the previous owner's name to mine. Now when I use my log-in a clean desktop comes up. In the user's folder is the house icon folder with the previous owner's name, and a folder with my name. All my documents are in that folder, so I haven't lost anything. But how do I get computer to boot back into my account?

I partitioned my hard drive to install windows. I rebooted, loaded up the windows disc. And then realized my disc only had one partition. I quit the windows installer without installing windows, went into boot mode and I can only see my bootcamp partition. Is there any way to get my osx partition back?

I installed Windows on Boot Camp, but the Application Install DVD is blank. To replace the DVD I have to drive 2-3 hours to an apple store or apple will send me one for $17. Is there a way I can get back to the Mac and delete the Boot Camp partition? The tool in control panel is not there because I could not use the Application istall DVD.

Ok here's the situation. I'm trying to fix my brothers laptop at the moment and reinstall Leopard. He installed ubuntu and it seems to have deleted the Master Boot record. I've managed to get Leopard to install but the mouse clicker doesn't work. I've managed to narrow down the problem to the MBR, the master boot record.
In terminal I've typed in sudo fdisk -u /dev/rdisk0
This has come up with the error "master boot record not found". I'm now trying to find a way to put the Master boot record back.
Does anyone have any suggestions on how to do this?

I have a boot camp Windows 7 installation that I also use with Parallels. When I have Windows running in Parallels, I can use my 3-finger gestures in Firefox to go forward and back, which is a feature I'm in love with. The problem is that when I boot directly into Windows I lose that feature, and it's really bugging me. Is there a program or even a firefox add-on that would fix this?

My iMac suddenly won't boot up. It stays black and simply beeps. Holding the start button shuts it down. It's about 3 1/2 yrs old, but has been well-maintained.

I've got a Mac Pro 2008, with 4 noisy hard drives in it.
I wonder if there is an easy way to manually spin down/up the unused harddrives when you feel for it? (That would be much easier that powering down the whole computer, and unplug the disks.

A couple of weeks ago I was running Parallels on my Macbook Pro. I had inserted a USB stick to get a file from it to windows. In doing so, the Macbook completely froze. I took the battery out and disconnected the power supply and waited for about a minute before booting it up again.
When I booted the Mac, it looked like it was starting up fine. However, it got to the point where it loaded my wallpaper, opened Finder and then froze for a few seconds. It appeared to try and restart again, got to the same point, froze and has been in a spin ever since.
I booted the Macbook Pro off the OS disc holding the D down to do the hardware test and it came back fine. I also reinstalled just the OS, but I'm still having problems. I ran the Mac if verbose mode too and I managed to get a crash log. I wasn't able to access it until last week as the Mac was in a spin. For some reason last week I put the Mac into sleep mode and the next day I was able to see the hard drive (though I'm not able to run anything as it seems to want the admin to login - which I am).

I noticed that on my macbook pro retina, i never heard the fans spin up.Â
I tried Prime95 to stress the CPU, temperature went up to 98°c and the fans stayed at about 2000rpm... I immediately stopped to avoid damages.  Â

So I've got a powerbook G4, thats 8 days past its warranty. Conveniently, it now won't turn on. It won't wont boot from CD. If I turn it on, I get a gray screen that usually just turns my computer back off, if thats not the case I get a screen that shows the finder icon and a question mark and then turns off.
All it will do is boot into open firmware mode. Currently the install disc is inside of it and I've tried booting the cd using "cd:, bxi" and "dir hd", and it can't open both. Does anyone know how to wipe the HD, and start the installer using firmware? Otherwise, I think I'll have to take out the harddrive and plug it into an external case and then wipe it.

I recently got rid of a partition I had made for bootcamp since I never use it, and would rather have the space back. I deleted the partition through disc utility, and then through the partition tab, tried to get back that space by dragging down the tab to restore the space originally set for the partition. When I go to apply this change, it notifies that my hard drive will be re-sized. I accept and then a few minutes later it comes back with the error "Partition failed with the error: Filesystem verify or repair failed" Does anybody know how I can restore this space successfully back into my main hard drive? I've attached some screenshots

When I go to turn on my MacBook pro nothing happens. No sound no hd spin no nothing. Last put computer to sleep and had it plugged in charging. Now when plugged in led doesn't turn green or any color just stays off and battery detector on side of laptop does nothing at all.
