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.

My iMac turns on but just beeps three times stops beeps more times and won't start up

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'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.

View 1 Replies View RelatedI 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
View 27 Replies View RelatedI 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.)

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.

Is this normal? I had no applications running!

After restarting when the computer powered up it goes to a grey screen and stays there and beeps 3 times continuosly. Do I need to take it for repairs?

I have been having crippling WiFi problems were I am forced to reload webpages 20-30 times before the page loads fully. I have tried many things and even upgraded the RAM to 8gb, and I still have the same problem. I have also tried resseting the WiFi, router, and iMac and it seems my problem is more complicated than that. I have run a test too and I had no lost packets. The strange thing is after a webpage not loading, if I refresh the page 20-30 times it finally loads!

I recently bought the Areca 1880ix-16 card and the backplane cable to hook to the mac pro internal drives - hooked up 4 x seagate ST32000644NS 2TB enterprise drives for an internal RAID5 with 6TB of space. Used the DX4 from transinternational to hook up my 2 SSD drives. The initial raid build time was just about 2 days (!) for the raid 5. Shortly after that I left town for a few days and came back to an alarm in my computer - one of the disks had dropped out. The rebuild time was again close to 2 days!. At thipoint I realized that if I was sitting there with that much data at risk for a 2 day rebuild, it would be agonizing and so I needed to go raid6 (which had been my goal from the start, but only 4 internal disks is very limiting). So I gave up on managing my storage internally and bought an istorage pro it8SAS external box connected by miniSAS cable. The raid5 had to complete the rebuild before it would let me expand to raid6. I added another seagate ST32000644NS 2TB enterprise drive (interestingly the drive that was originally listed as failed has caused no further problems at all) and expanded the raid to RAID6 with the same capacity but one extra drive for parity. The rebuild now has been going on for almost 48 hours and it's at 53% I had NO idea the rebuild times would be this long. I do have 2.3TB of data on the array, so I'm not sure if that prolongs it vs. an empty array. But just for others info, take into consideration these times when deciding what your own needs are - I bought a high end (AFAIK) raid card, running in a high end computer (mac pro 3ghz octocore with 16GB RAM) and quality enterprise drives, and it's still maddeningly slow to rebuild. Hopefully once it's up and running, this will all be forgotten, and if I ever have a drive fail, I know I can still lose another one without any data loss. RAID6 seems the only way to go given these times for rebuild. FWIW, I also put in another 3 drives - old 500gb drives I had sitting around and built a secondary RAID5 array since I had the space, that completed in around 36 hours or so, and was done during the original raid5 rebuild.

The past couple of times I've tried to send an e-mail have resulted in an error message saying "The message could not be delivered and will remain in your Outbox until it can be delivered. The connection to the server [URL] on port 25 timed out." I know I have my account set up right, as I've been using it like this for years. I went into GMail in Safari and could send a message fine.
View 4 Replies View RelatedI've been using my mac religiously on a daily basis for almost a year now. I have noticed that progressively the boot time and shut down time is getting longer and longer. And I understand as I install programs and use the laptop more, it's going to get slower and slower but right now the boot time and shut down time is more than I would expect.
For boot up, the only applications that open on login is Mail and Quicksilver.
Is there anything I can do to reduce the boot and shut down times?

It first only boots to white screen...reboot...comes up to white screen with Apple in middle...reboot...comes up to blue screen...reboot...boots fine and operates fine.  I do notice that it reboots every once in awhile for no apparent reason.Â

View 2 Replies View RelatedI have a MacBook Pro with bootcamp and Windows 7 as well as OS X (unsure of version number at this moment, but think its 10.5). On the Windows 7 side, webpages load quickly in both Firefox 3.6.10 and Internet Explorer 8.0 and I rarely have trouble. On the MAC side, webpages are often unbearably slow to load and often do not load at all or time out or stop halfway through loading. This is both occurring in Firefox (latest version) and Safari (latest version).
View 4 Replies View RelatedThe mac in question is a late 2009 27" iMac 2.8Ghz i7, with the stock HD, and graphics options. With 2x 2GB sticks of Apple RAM, and a further 2x 2GB sticks of Kingston RAM. The machine was purchased in March, and has worked flawlessly until 10.6.5
The machine is still in Warrenty, I can take it in if I need to.. but here in Holland that usually means it has to stay in shop for over a week. The closest place to our residence is a long distance and.. yeah, it's just not easy, it really is a last resort.
When we updated it to 10.6.5, it required a restart. Upon restarting it beeped for a number of minutes before it started restarting itself and beeping numerous times before it loaded the operating system. This was two weeks ago.
Since then, when she has tried to boot it it has either:
A) Beeped 9 times, 3 short - 3 long - 3 short;
B) Booted normally without issue.
When "A" happened, she's been turning it off and waiting for a few minutes before trying again. If it did not load first time - after a few attempts, it always booted.
Yesterday I finally had some time to take a look at the problem, and discovered that 9 beeps means there is a hardware issue. Most likely a RAM issue.
I checked the "About this mac" and "more info.." area's of her computer and saw nothing unusual. The machine recognised every part including all 8GBs of RAM.
I looked into information regarding faulty firmware and found nothing solid - so I left it alone.
Today we found that the machine does not boot up at all. Waiting any length of time and trying to boot the machine up again does not result in a successful boot.
I then took the following steps - and got the following results:
-I removed all 3rd party RAM, and booted - received the same 9 beeps.
-Moved the stock Apple RAM into the upper slots - received a single long beep repeatedly. (No RAM detected?)
-Replaced the Apple RAM in the lower slots (where it has always been) - received the same 9 beeps..
So I was on my MacBook and all of a sudden the screen gets some weird lines on it and then freezes. I turn it off and turn it back on and I get a black screen and 3 short beeps and it keeps going. Well I called apple and they said it is a hardware issue. I goggled it and found it is a memory issue (maybe).
