MacBook Pro :: Machine Chimes After Every 20 Minutes
Nov 4, 2010
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.

Within the last couple of weeks, my system has started to hang like clockwork every 30 min. No idea what caused it and don't remember anything in particular installed or done during that period. Unfortunately, when it hangs - there is nothing kicked out in Console and there is no recurring "this process was running right before it happened" clue.Â
Details on system:
Macbook Aluminum (late 2008)
Mac OS X Lion 10.7.4
2 MB ram
30% harddrive space free (approx. 90 GB)Â
What I've tried:
-repaired permissions
-repaired drive
-cleaned up drive via Cocktail, CCleaner, CleanMyMac and Disk Doctor
-reset PRAM
[code]....
Info:
MacBook, Mac OS X (10.7.4)

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.

I keep my time machine HD unplugged from my laptop to reduce the clutter, when i plug it in, time machine starts automatically backing up. It says "Preparing Backup..." and it stays like that for a while. I've had it like that for about 15 minutes.

I've been trying to install various builds of snow leopard on my mac pro with no success (latest is 10a380). I start the installer, choose an install partition, click on 'install', the install window comes up, telling me the installation should take 'around 45 minutes'.
It copies a load of files to the hard drive, then about five minutes later the machine re-starts, and I am dumped back into my normal leopard installation. If I look at the discs I'm installing to I see a 'Mac OS X. install data' folder containing a lot of .pkgs, and that's as far as it ever progresses.
I've tried booting up directly from the install DVD, and this never works either: it always dumps me back into my normal leopard installation.All the disks I've been trying to install to are GUID formatted, permissions repaired, etc.Anyone got any ideas what can be going on?

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'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.

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 purchased my MBA last night and let it charge over night. This morning my battery decreased to 97% within the first 3 minutes. It is now at 87% and it's been only 10 minutes. Is this normal? I haven't done any cycling yet.

I have an old MBP (2.16 GHZ); 2 Gigs of Ram and 120 Gig hard-drive. I have used my battery a handful of times since I got it, and now when I try to run off of battery power, it says it is fully charged, but after unplugging it, it dies about 3-5 minutes later. I remove the battery after the shut down happens, press to button on the bottom and all five green lights are lit indicating it is full. I really can't afford a new battery... And it doesn't seem like it is the battery anyway.

I've got a white macbook 2.16 I believe. The screen/display will turn on when booted up, but only stay on a few minutes. I got it off craigslist this way. When I first got it, it wouldn't come on at all. I replaced the inverter with one I got off ebay that was probably used. I have tried 4 different inverters in it (all used I think) they all respond the same way. Screen comes on for just a few minutes then the light goes black. If I disconnect the power to the inverter after it shuts off, then reconnect it, it will light up again for a couple seconds only. If I leave it alone, it will come back on after about 20 minutes.
Does this sound like I have a bunch of bad inverters, or a bad lcd screen? It also drives an external monitor flawlessly the whole time and keeps an image displayed on the screen even when the light dies.

I have noticed another weird MBP 2010 bug. I have the 15" i5. The cursor disappears for a few minutes sometimes. I haven't noticed what card is on and I've been doing just random stuff. I mouse around and click around and after a few minutes it comes back. The keyboard responds normally. Everything else is normal. The cursor just completely takes a vacation for a few minutes. The really weird thing is, is I've seen this several times in Windows XP SP3 in BootCamp as well! Maybe it's the crap NVIDIA driver.

I have a MBP running 10.7.3. All of a sudden it loses 55 GB of hard disk space in a couple minutes. I start getting pop-up warnings about space. Then, if I clean a couple files (maybe 1GB) worth, the free sapce begins to return. Then it heads back down again. Literally 10 GB in a couple minutes.Â
