No boot, continuous beeping

Hi All,
My wife's macbook air (13 inch late 2010 model) no longer boots. The screen does not come on (no grey boot screen) and when powered on there is continuous beeps. ~1 second beep, 2 seconds silent, 1 second beep. It will continue to beep as long as you let it. Pressing the power button turns it back off. The fan will start to run on high if the computer is allowed to keep beeping for more than about 10 seconds.
Any ideas? Thanks

Hardware failure; most likely bad RAM.

K9vgm-v continuous beep on boot sometimes, reboot and it stops

Hi All,
Yep it's intermittent, the computer is now about a year old and never had a problem until about a month ago when on switching on, mid way through the boot process I got a continuous beep, I could still log in to my session whilst beeping all the while. re-starting the pc resolves the problem, until next cold boot it would seem and then, not always.
It's an award phoenix bios. I have 2 x 1gb dimms installed, is the continuous beep a memory problem do you know please? Is it possible that memory problems can be intermittent?
Thanks,
Brownster.

After ram upgrade, continuous beeps, but then boots ok?

I just upgraded my ram to 2 x 4 GB 1067mhz DDR ram. The brand is Corsair. Further details here: http://www.ebuyer.com/164771-corsair-4gb-ddr3-1066mhz-laptop-memory-cm3x4gsd1066. I purchased this ram for my macbook pro mid-2010. The comments in the link indicate it should work with my macbook.
Unfortunately - and I think it's to do with the ram - when I turn the power button, I get continuous beeps. But weirdly after holding down the power button (off), letting it go, and then turning on again a few times, the MBP will eventually boot up fine. Doing a 'system report' indicates the ram is operating 'OK'. Although I'm a bit skeptical about that!
I thought the ram might not be installed properly so I pulled it out and pushed it back in again. But still the same problem.
I think it's really odd that the MBP will eventually boot up, so I'm not 100% sure it's the ram.
Does anyone have any ideas how to fix this?

So-called value RAM like Corsairs value line or Kingstons value line are often problematic in Apple machines. Apple tends to set its design standards quite tight in terms of RAM for things like clock timing, latency and so forth.
"Value" RAM lines are in fact the exact same modules as used in companies better, machine-specific or configuration-guaranteed modules, but the value RAM failed the stringency QC testing required to make the higher level product cutoff.
All RAM tends to start out the same, and then the level of quality specificity or guarantee is based on various QC testing - the "good" stuff that places like Crucial or Kingston or OWC sell as system-specific passed or exceed all QC test limits as specified by the computer manufacturer. The value or non-system specific stuff is the stuff that did not make the grade for the higher QC standards (but it still may be okay in a system that allows sloppier specs than a higher end system like an Apple logic board's requirements).

IMac continuously beeps three times when FireWire HDD is attached

Hi there,
Whenever I reboot my iMac while my external FireWire HDD is attached to it, it continuously beeps three times in a row. I detach it, and restart the iMac, and voila, it boots again!
Any ideas why it can't boot while my FireWire HDD is attached to it? It doesn't seem to be a RAM issue as is specified here: http://support.apple.com/kb/HT2674?viewlocale=en_US

It could be a firmware issue with the firewire drive.
Have a look at the article in this link

Satellite P10-504: continuous beeps when it is turned on

My P10-504 emits continuous beeps soon after it is turned on. It will stop beeping and reboot itself but go back to the continuous beeps. The way to get it to boot is to hit F2 and go into BIOS and then exit, then it will boot up OK.
I have depressed the keys when booting up to see if it might be sticky keys, but that has no effect.
If I take the all the memory out when it boots up it beeps to tell me I have no memory. If only one bank is in the continuous beeps return.
The one then it tends to do in Windows is to automatically bring up the search tool and constantly refreshes the screen unless esc is hit.
Any ideas or other tests to do??

Hi,
I don't know where the problem is, but maybe you should try reinstalling the BIOS.
If it doesn't help please contact the ASP in your country.

PB G3 333 - Continuously Beeps - Won't Start-up

As the subject says - I push the on-off button, I hear the Mac start-up sound, the hard drive starts to whir, then a continuous beeping starts. Not just 1 or 2 or 4 beeps - but a continuous beeeep, beeeep, beeep, beeep ... The screen is black and nothing else happens.. The beeping continues until I pull out the battery (no problem there) and the power supply.
I have tried removing and swapping the RAM chips - no change.
Any ideas?

terry,
I am unfamiliar with that symptom. Here are the POST tests for your Lombard:
http://docs.info.apple.com/article.html?artnum=58183
What is interesting is if it were in fact one of the above, you would not hear the normal startup chime.
Since I don't know what the answer is, I would try the basics:
- disconnect any and all peripherals and remove the optical drive from the media bay;
- reset the power manager and PRAM:
http://docs.info.apple.com/article.html?artnum=14449
http://docs.info.apple.com/article.html?artnum=2238
- if still a problem, remove the HD and see if it will start to the flashing '?'; if so, replace the optical drive and see if it will boot to a CD.

Dell Inspiron 15R wont turn on (continuous beeping)

Dell Inspiron 15R (5537) suddenly wouldn't want to start. When boot up, nothing seem to appear, blank screen, no logo, no text, nothing. there is a continuous beeping, it not 2 beep or 5 beep or any number of beep, it just beep continuously, never ending, until I turn off the laptop.
Did some searching around on the web, forum, and so far I attempted:
-Checked ram and hard-drive to see if it fully connect.
-Turn off computer, unplug battery and ac power, press the power button for 30 sec.
still haven't resolve the problem yet.
Next, I try to do a Pre-boot System Assessment, FN+Power. Took SEVERAL attempt to finally got it to run Pre-boot System Assessment. Hold FN + Power, hear beeping, turn it off, Hold FN + Power, hear beeping, turn it off.
Did that for about 20 times and finally got Pre-boot System Assessment instead of the beeping.

This is the result I got from it, Currently doing the remaining memory test. It taking a long time, ill have an update once that is done, it stuck on 98%.

This paper discusses troubleshooting steps for notebooks that are not turning on. Typically it could be one of three issues, No power (no power to the notebook), No post (the system has power but is not fully turning on), or No boot (the system has power, it is turning on, but it is not booting to the Operating system).
From your post it is obvious that the notebook has power, but it isn't fully turning on. I would have to say that this is a No post problem. This paper will go over further troubleshooting steps to help determine the problem.
If the notebook is not starting up or showing a blank screen:
Remove any peripheral devices that are attached to the computer.
Peripherals include:
Printers
Scanners
Media Card Readers
Mobile devices such as smart phones or tablets or portable digital assistants or MP3 players
Digital cameras or video recorders
USB storage devices
Remove the computer from a docking station if it is in one
Remove any CDs or DVDs in the optical drive
Remove the AC adapter from the computer and remove the AC power cord from the wall outlet.
Remove the computer's battery. For instructions on how to do this, consult the Online Owner's Manual.
Press and hold the computer power button for 15 seconds.
Insert the AC adapter plug and make sure it is seated properly.
Plug in the AC power cord to a known good working outlet.
Press the power button to see if the computer turns on.
If the computer starts, turn it off and put the battery back in.
Press the power button to see if the computer turns on.
If the computer starts, turn it off and continue replacing peripheral components until you determine
which one is causing the failure.
Please let me know if this helps out.

I did what you told me, there is power coming it, it just wont start, like i can hear the fan running, the power led is lid up, it just wont boot into anything, screen is blank and there is a continuous beeping sound, beep ... beep ... beep .. beep.. beep ... beep ... beep .. beep.. beep ... beep ... beep .. beep.. beep ... beep ... beep .. beep.. beep ... beep ... beep .. beep.. beep ... beep ... beep .. beep.. it goes on and on.
if i keep turning it on and off, if im lucky, very rarely, it boot into the OS or into Pre-boot System Assessment. Once it boot into the window OS, i attempt to do a factory reset, but as soon as it restart it fail to continue and just beep.
any other suggestions?

GTX 8800 OC Continuous beep

Hi all.
My drama's this time seems to be a problem with my primary Card. At random times, and often the PC freezes, screen goes blank but not necessarily black and card emits a continuous beep till I reset. It also happens at startup time as windows is trying to load, but does not seem to happen if I boot to Safe mode. I'm also now having issues with how to rebuild my array after a single disc error. I have raid 0+1 on 4 discs by the way.
I am using Nvidia driver 176 after I rolled back from the latest just to see if it made a difference, it didn't.
It's a worry.
Any idea's?
Cheers
Rod

I was hoping that wouldn't be the first answer. Here's my problem there. I am running a liquid system and both cards are attached to each other by a solid link, I thought to disable the second card by pulling it's power leads but it protested so bad I had 2 cards beeping in harmony. I have already tried disabling SLI. I just checked PCI-E voltage via Dual Core Centre (which as a rule I don't run), I lowered voltage to 1.80, it was at 1.85 (not my setting).
If I have to pull the plug out of my system to remove a card I'm looking at major surgery. Is there any other way?
I have run memory checks on all sticks and they are fine.
Could the PSU be to blame? It is only a 600W after all and I am running a lot from it according to overclockulator.
I really value your opinion and if removing and testing the cards one by one might lead to an answer then so be it.
Raid fixed itself by the way, just needed time and no input from me
Cheers mate

Nothing but continuous beeping

That's all I get when I start up my computer. Continuous beeping.
I have the KT3 Ultra2 board.
I came home and it looks as though it had been restarted. It was at the Windows XP OS selection screen (for some reason I have XP home and pro edition installed so it has this when I start up) and it was locked up. When i hit reset, it wouldn't boot up, just the continuous beeping thing. The lights come on the drives, I can open and close the CD trays, but nothing on the screen. The beeps are infinite, the same pitch, and at equal intervals.
I just got a new processor, motherboard and RAM. After switching to a new power supply, I fried my ABIT KT7A motherboard. I don't know how it happened but it stopped working. Now I've had this motherboard for less than a week and it won't start up either.
I read some stuff ont he internet and I tried reseating the memory and video card. I've also tried switching power supplies, to no avail. I haven't been able to find out what the continuous beeping means on an AMI bios.
Anyway, if you can help me out, it would be greatly appreciated. Thanks in advance.

Tried all this.
Went to the store and got a new stick of DDR 2100. Made sure it was seated well and tried it in all three slots. Tried a different video card as well, no luck there.
A memory problem, though, makes sense. The little LEDs on the USB bracket show that the system gets to the memory check part (lights 1, 3 and 4 are red, light 2 is green) and stalls out. I read somewhere that if there is an error in the external cache, the system might read it as a memory error and I was advised to reset the external cache. However, I have no idea what this means or how to go about doing it. Could this be a possibility?
Thanks,

Equium L350 wont boot, just beeps

Hi Everyone,
I have an Equium l350 laptop model psld2e-003003ks.
It wont boot up it just beeps continually there doesnt seem to be any specific sequence of beeps just continual.
I have tried F8 and started it in safe mode which it does, but when click on "start" it displays "search" and the letter G scrolls along the search box.
I cant do an antivirus scan as it asks for my administrator password which I cant put in as again a series of letters or numbers just scrolls along the box where you input your password.
2 evenings previous I was using my laptop in bed and I got a blue error screen but managed to reboot it ok.
The next night it was fine too. I'm unsure as to whether I have a virus problem or a hardware prob.

Hello
> but when click on "start" it displays "search" and the letter G scrolls along the search box.
This would mean the key G on keyboard stocks and so a continuous beep appears. Maybe you can solve the problem if you try to repair the key: Just move the key a little bit but be careful.
Generally speaking if you exchange the keyboard your problem should be solved and a new keyboard can be ordered from an authorized service provider in your country. On Toshiba website you can find a list with all ASPs.

Grey screen and continuous beeping (macbook pro 2010)

Hi, I unplugged my computer from its display/keyboard/HDD setup to use it portably and then upon waking it from sleep - it froze and a continuous beeping began from within the computer.
When I started the computer I get the bong and white/grey screen (completely blank) and the beeping begins immediately. But thats as far as it goes.
I've looked online and there's a lot said about RAM related beeping but having removed the RAM i know this not to be the case as the beeping I hear is much quieter and far more regular than any of the loud RAM beeps.
Safe boot, pram reset and cmd s did nothing.
Any ideas whats wrong and how to solve?
Thanks

MSI MegaPC 651 - System Won't Boot (Long Beep)

When I attempt to power on the PC I recieve a continuous beep signal.
The Beep is approx. 8 seconds long, followed by 5 seconds of silence. The signal keeps repeating itself until I turn off the power.
Obviously, the system is not passing POST so I can't get any video or access the bios.
The cpu is a P4 2.4ghz 533fsb.
The memory is a single 512mb DDR 333 chip.
I've plugged the CPU into a second motherboard and it appears to work fine. I've tested the ram in the second mother board and it appears to work fine.
I tried a stick of DDR400 ram from a known-working system and that did not seem to correct the issue.
One thing I noticed in another similar thread is someone mentioned that i should make sure my CPU fan is plugged in.
~ My Fan is plugged in (came with MSI Barebone), but it doesn't spin. I've tried plugging in the fan that came with my CPU and that one doesn't spin either. My Intel Board that i use for my desktop allows me to boot without a system fan plugged in, I've never heard of a mobo that doesn't. The system isn't even on long enough for the CPU to be over heating.
Please Advise.
-Josh

It is a memory issue. There is something weird about this motherboard...
I got the system working, and i couldn't figure out what i had done differently. I then installed windows.
I let it run for a few days until i realized that the RAM that was in there was the DDR 400 ram from my other desktop, instead of the DDR 333 that I had intended to use.
I took the DDR400 out, and put the DDR333 in and again.... BEEEEEEP. (8 seconds)
I put the DDR400 back in and still... BEEEEEEP. (8 seconds)
I know neither stick of RAM is bad because they have both been used successfully in my other desktop system upon the first try. Its like the MSI has some sort of connection problem in the memory bank, and I lucked out on one try and got all the connections to line up.
If anyone has any suggestions, please advise, because I'm back to square one again.

MSI G31M3 V2 not booting no beeps

i have a MSI G31M3 V2 motherboard not booting and no beeps.tried many ways (including clearing) bios to boot up to post screen.
so system was taken apart just to ram sticks but still no beeps but fans runs .
when remove the ram sticks continuous beeps goes on.
system details
m/b - MSI G31M3 V2 v1.1
processor - intel duel core e5400
ram -2x kingston 2gb 800
vga- nvidia 9600gt

That PSU is not even good enough to use with a modern system using onboard graphics let alone one with add on VGA card. +12V~17A on a 550W PSU? Take that thing as far into the Outback as you can and lose it somewhere.
A good 350W would have at least +12V~20A.

0.6, with same problem as i am during installation continues beep on mac which unusual and it tooks longer time and didnt reboot the system. kindly help

Continue beep while installing leopard, kindly help to fix this problem and it took many hours only gray screen and apple logo it didn't proceed the reboot

Continuous Beeping noise on Startup and at other times

My iMac is over a year old. I have no idea what is wrong or happening here but below is what happens.
I hear a continuous beeping noise from my iMac at times. I had Firefox open and when it started beeping, a little search bar opened up at the bottom left of the browser so I assumed it was a sticky key on the keyboard so I pressed the spacebar and the beeping stopped and the search bar disappeared. This happened a few more times while I was using the browser.
The other day I started up my iMac and before it opened to the desktop it showed a small iMac HD icon so I clicked it and it started up normally, but then the beeping started so I just hit the spacebar and it stopped. Now I do remember after I turned the iMac on I accidently pressed some keys on the keyboard so this maybe why it showed the HD icon but I don't really know.
Yesterday morning I turned the iMac on and came back to hear it was beeping again. It was just a fast non stop beeping, too fast to count the beeps. It had loaded into the desktop so it was all good apart from the beeping, again I pressed the spacebar and it stopped.
Yesterday afternoon I got more beeping. Beeping is not just on startup it must be something else. I was using Firefox and was trying to scroll down the page, yet it kept jumping back to the top not letting me scroll down. This happened the other day when the beeping started. Anyhow I closed the browser and the beeping starts. I was able to turn the sound down and that got rid of the beeping, turned the sound up and the beeping still there.
I tried this so far...
unplugged keyboard and started up mac = no beeping
plugged keyboard in and started up mac = beeping
Again this morning I turned my iMac on, and beeping happened again, this time I clicked System Prefrences and the beeping stopped. I then clicked the Sys Pref folder red icon to close it and it made a different noise, but closed. I then opened up Firefox and went straight to my bookmarks to find a link, it wouldn't let me scroll down my list of bookmarks either, then the beeping started so I closed Firefox. Then I heard a loud sratchy type noise, it was much louder and hearing this has now made me think, something is not right.
Firefox version - 3.5.3
Mac OS X version 10.5.8
I don't want to set PRAM or those settings yet unless it's needed as I don't know what settings/network etc it will remove or change.
I appreciate any help:) thanks
