High-pitched beep/sound during sleep and shut down modes

I just wish to check whether is it normal that there's high pitched beep (not very loud but can be heard in a quiet room) which seems to be from the LED or AC Adapter during sleep mode. The beep sounds continuous when the computer has been shut down or in off mode while the main plug of where the ac adapter is connected to is still on. Is this normal? My computer works fine. Battery is charging fine. I just want check whether is this normal. It is has been like that ever since I bought my computer on March 2012.

Hello Huanwei,
It appears that you can hear a "high pitched beep" coming from the notebook while it's in sleep mode or even off, when the power adapter is plugged in and "on". I will try to help you with this.
Normally, this should not happen. Beeping from a computer may happen during start up a few times to indicate components enabling, but any constant beeping or being while the computer is off shouldn't happen.
Does this occur, if the AC adapter is not connected to the notebook when it is in sleep mode or off? Do you only notices this, in a specific location? (office, etc.)
I would suggest, depending on the setup of things. Taking the notebook with no AC to another location in the house. A quiet one, make sure your not near any other electronics (no watches or cell phones either) let the notebook sleep and see if you hear the beeping. If not, then power it off and test again. If no beeping, this is good and the notebook is fine.
Repeat that same test with the power adapter connected ( again no other electronics around you). Listen while it is "sleeping" and off to see if you can hear the beeping again.
If you do disconnect the AC from the notebook , but leave that connected to the wall and take the notebook out of that location, go back to see if you can hear beeps again. If you do it could be the AC adapter. If you don't then it could be an issue with that only when it's connected.
If there was no beeping when the AC was connected in this "testing location", then I would guess it is something else within the house that is beeping (we have seen that before). In which case you'd have nothing to worry about in regard to your notebook.
Let me know where the above leads.
Thank you for posting on the HP Forums.

As I said, a weak or dead PRAM battery can reportedly cause odd startup issues. If it has never been changed in six years, that's a really long-lasting battery, even if the iMac was kept on continuously.
They are pretty cheap from the right source, so you may want to try changing it.

Sleep and Shut-down menu commands

Our 500 MHz Power PC G3, upgraded to system 10.4.6, is a great machine and a real work horse for us. However, it has been acting up lately. The apple symbol drop down menu command that puts the computer to sleep, restart, shut down etc. will not respond. The key board commands for sleep etc. also don't work. I tried the Disk Utilitly- First Aid, both Disk Repairs and Permissions. "No repairs were necessary" for both. I even reinstalled OS 10.4.6 which seems to have complicated the problem and ate a big chunk of our precious little harddrive memory. Now every time I start up I get the warning message, "Application Launch Failure" The applicaton "Transport Monitor' could not be launched
because of a shared library error:"8<Transport Monitor><Transport Monitor><HotSyncLib.PPC><"
Could this be the root of the drop-down menu problem?

Do your MacBook make a high pitch beeping sound?

Just got a late 2011 MacBook pro with SSD hard drive (17 inch i7).
I have noticed an almost inaudiable high pitch 'morse code' like beeping coming from the machine. Maybe the SSD being accessed?
I do have tinnitus and have been known to become irritated from low Hz monitors and TVs in the days when they operated at 50-60 Hz. So maybe something in the machine is operating at that fequency.
It may be nearly audible, but it's driving me mad when the music is off and I'm trying to concentrate!
Does anyone else experience this?

Does the beep sound similar to this video? Skip to the 00:44 mark to hear the sound. If the sound is this one that means that your Mac is trying to update its EFI.
Would you mind recording a soundbyte? That could be really helpful. It's not possible that the sound is coming from the SSD, perhaps is your fans.
Hope that helps.
P.S. If you are too bothered you can also make an appointment at your local Apple Store Genius Bar.

Lenovo Miix 2 10: Sleep and shut down causes restart

I fairly recently ran into a problem with the Miix 2 10. It works perfectly fine otherwise, apart from two issues:
1. I can't put the computer to sleep. Hitting the power button, or selecting sleep from the power menu, or waiting long enough for sleep to engage via power options causes the screen to turn black, the computer won't wake by pressing the power button, and after a bit (under a minute?) the Lenovo boot up screen shows and the computer boots up "normally". This happens no matter how sleep mode is engaged. Basically the same behavior also happens when I select Shut down from the power menu, the computer shuts down normally and then after a little bit (under a minute again) the computer boots up again. The only way to shut down the computer so that it'll stay down is to hold the power button down so long the computer shuts down forcibly. Or wait for the battery to run out...
2. Almost no Windows updates will install. All of them fail with the following message: Code 80073712 Windows Update ran into a problem. I've searched high and low for a solution to the Windows Update problem, tried everything MS had to offer (short of factory reset or reinstall) and nothing has worked.
Truth be told I'm mostly worried about the first problem, not so much the Windows Update one. The sleep issue essentially stops me from using my Miix 2 10 as a tablet at all, I have to treat it like an always on laptop, and I have to even run screensavers to prevent possible screen issues because it's always on ("turn off screen" seems to also shut down the computer). Our local Lenovo only supports corporate computers, servers and professional laptops, and as far as I can see I can't contact Lenovo US in any way other than phoning them, so I'm more than a bit stuck with this.
As far as I can tell this is related to either BIOS or the CPU driver package. I installed the latest updates some time ago and afterwards this behavior came in, making it almost impossible to really use the unit. Should have known better than to update any drivers when everything was working fine...
If anyone has any ideas that could help, I'm all ears. I've heard there are some BIOS settings related to power management that could cause this, but you can adjust absolutely nothing of any use whatsoever in the Miix 2's BIOS. It's completely useless when it comes to that. I'd really want to try and roll back the BIOS drivers, but that's not possible since they aren't available anywhere, so I think I'll just have to return the unit.
EDIT: Just in case it matters, if I look into the Device Manager I can see that many if not most of the stuff running on the Intel driver package (the Baytrail processor driver package includes a lot of stuff like the camera drivers) seems to be saying something about the power states that may or may not be relevant: Power states D0 (full power) and D3 (Sleep) are listed as supported, and the power states are mapped as follows:
S0 -> D0
S1 -> Unspecified
S2 -> Unspecified
S3 -> Unspecified
S4 -> D3
S5 -> D3
A couple of them, for example ACPI X86-based PC, say D3 to S1-3 as well.

i think i find solution.
after instal baytrail driver, without restart i instal gpu driver direct from intel

Sleep and shut-down

Hi
I wonder if it's normal that, when shutting down my MBP, I've got to wait for it to be totally turned off before I can close the lid. If I close the lid during the shutting down process the MBP very often go to sleep.
If this is the normal behaviour, it doesn't seems to me so much efficent.
I suppose very few code would be needed to have the lid-linked sleeping command excluded when the shutting down process starts.
PS: I use 10.4.9, so maybe the problem as been fixed in leopard.
bye
Angelo

I have been told previously by more than one Genius at the Apple store that the shut down function should not be done very often, just to put my laptop to sleep most often. I don't know if that is different for MBP. This is my 5th apple laptop (original 'portable'mac, powerbook 180, clamshell ibook, wallstreet powerbook, and powerbook g4) and have always relied on putting them to sleep rather than shut down on a day to day basis. So your issue is not usually a problem, since closing them puts them to sleep as you noted. If you are shutting down, I think you do need to wait for it to complete the process before closing your laptop.

System sleep and shut down not working after upgrade to windows 10

HiI upgraded my OS from win 8.1 to win 10.After the upgrades the system shutdown and sleep are not working properly.It's like when I shutdown/sleep the system ,the screen shuts down but the power key keeps glowing and also the battery keeps draining.So eachtime I have to foercefully press the power button to shutdown the system. I have updated the display driver . Please someone suggest, what to do ?

Hi there , Thank you for visiting the HP Support Forums and Welcome! I read your post on the HP Support Forums and seen that you are having issues with your HP Pavilion 15-n260tx Notebook PC and the Sleep/Shut down options. It sounds like you might be having an issue with one of the features of Windows called Hybrid Shutdown that is used for the Fast Startup feature. Here are a couple of links for you about Fast Startup, Hybrid Shutdown and How to Shut down your Notebook completely. They also have some troubleshooting steps in them. 1. Fast Startup - Turn On or Off in Windows 10.2. Shut Down Computer in Windows 10. If those do not work, I do have some more documentation for you to read and try. 1. Shut down (turn off), sleep, or hibernate your PC - This document is from Microsoft. 2. HP Notebook PCs - Managing Power Options (Windows 8)3. HP PCs - Sleep and Hibernate Issues (Windows 10, 8) Sometimes a BIOS Update will work. You can update all of your drivers by going to the HP Driver's website or by using the HP Support Assistant. On the Driver's page there is not an update for the Windows 10 Column, but there was an update that just came out under Windows 8.1 on Aug 7, 2015 that should work for your Notebook. Another fix that may work is to Run the Troubleshooter. Please follow this link to run the Windows Update Troubleshooter. I hope this helps! Have a great day!

Sleep and Shut Down problems

Here's the problem: several months ago my iMac went to sleep and when I hit the space bar to wake it up, the pinwheel started spinning and there was a series of ten clicks, a pause, and then ten clicks again, over and over. The clicks were coming from the hard drive area in the computer. I did a hard re-boot and it was fine for awhile but then the problem came back when the hard drive went to sleep.
Then, when I would try to start it up after shutting it down, a similar thing would happen: no desktop, one click, then an infinite series of ten clicks from the hard drive with a pause in between each series.
I tried unplugging everything, letting it click away for as long as it felt like it. Eventually the clicking stopped, but the folder with the question mark came up. I restarted and restarted over and over and eventually the computer came back up with no problems.
I called Apple and they felt it was a software issue. They talked me through some diagnostics, resetting the PRAM, Disk First Aid and then finally wiping the hard drive and starting over. I reinstalled my applications and it worked fine for awhile; I was able to shut down and start up, as well as put the drive to sleep without any problems.
Then, it happened again on shut down and subsequent start up. Once again, I restarted over and over and eventually it came back up. Since then I have turned all the Energy Saver options to "Never" and haven't shut down since. Except once when the power went out. I had the same problems starting up.
I still think that it's a software thing because otherwise I haven't had one problem with this beauty of a machine.
Anybody got any ideas?

Zambini, welcome to Discussions. I would tend to think you have a hardware problem. The clicking is probably the hard drive and the reason it has trouble starting is if the hard drive isn't functioning properly then the Imac isn't finding the OS on the hard drive and can't start up properly. I would definitely get ahold of Apple and let them know what is going on STILL and that reloading has not fix it. It may also be the motherboard but would definitely think hardware. Good luck and let us know how it goes with Apple. Bob :~))

High pitched beeping noise

I have recently purchased a 60 gig iPod and whenever I try to listen to music or watch a video that I did not purchase from iTunes a very loud, very high pitched beeping noise accompanies it and pretty much drowns out the rest of my music. The beeping is incesant and does not stop throughout the whole track. This did not happen with the iPod nano that I used to own and it only happens on music that I did not purchase on iTunes or did not transfer via cd. I have had most of this music on my computer for a very long time. Is there a way to fix this without burning over 500 songs to cd. If so please tell me, it would be greatly appreciated.
Windows XP

you are the second person to tell me that it's a hard drive problem. i'm starting to think that that is the problem. it really hasn't done that with other programs, but it does very rarely. i have the upgraded hard drive for the macbook pro. if i were to have it replaced, would it cost a lot? i'm still in the one-year warranty by about 20 days. do i just take it to an apple store and they will fix it?

PC is not going to sleep or shut down after upgrade to Windows10

Hello,I upgraded my laptop from win 8.1 to win 10.Now when I close the lid or press the power button, the computer turns the screen off, turns the WIFI off, no more hard disk activity but it is not going to sleep.Also when I shut it down it goes throught the same procedure but never turns off.To start again, I have to keep pressing the power button to turn it off, then turn it on again.I did the powercfg - energy and got this in the report, "USB Suspend:USB Device not Entering Selective Suspend"When the computer had just started, I don't get that message, it also goes to sleep and shuts down normally, while later, I get this message in the report and no longer sleeps or shuts down.Any suggestion ??Thanks

My macbook pro 2006 fan goes high and then makes a fast beep and shuts down it been happening since i updated

my macbook pro 2006 fan goes high and then makes a fast beep and shuts down it been happening since i updated it should i update to lion?

No, this problem should be solved.
The MBP shuts down when too hot, to protect itself. First see if it is a process running astray: start Activity Monitor (in Applications/Utilities) choose <all processes> and click the %CPU column: are there processes that are using more than 50% cpu power? If yes click it and quit it, and tell us which one.

MacBook gives 2 high-pitched beeps at 7am

Don't have any scheduled events at this time, but the MacBook gives these two high-pitched beeps at around 7am on most (not all) days. Even does it when asleep. The beeps do not appear to be coming from the speakers and they're unlike any system sound, so is there something on the motherboard or in the drives that could do this? Is it a warning of impending failure?

Suspected that but how to diagnose what the problem is? System Profiler reports that the RAM (2 x 1GB Kingston) is OK and Disk Utility 'Verify Disk' returns 'appears to be OK'.

Qt high pitched squeeling sound

Hi
I have a MOTU 828mkII on a G4 Powerbook with OSX 10.4.8 and i'm getting this very high pitched beep/squeel and clipping sound whenever i try to play any audio in Logic Pro 7.1 or Reason 3.0 and also when watching videos in iTunes. However, playing music in iTunes is fine. I get the same problem when watching quicktime videos online (e.g. movie trailers from apple.com).
I reinstalled the latest MOTU drivers and it didnt fix it. I tried reinstalling QuickTime before and it fixed it but when the problem came back and i tried it again it didnt work.
I suspect its a Quicktime codec issue but can't be too sure.
Anyone experienced anything like this? any suggestions?
Thanks.

You say it's not mechanical, but it does sound like it could be a fan or drive bearing. Especially if you are in a warm environment.
Do you have external speakers connected or are you using your internal speaker?

Occasional single high-pitched beep

Every so often I hear a single, short, high-pitched beep emitted from my MacBook Pro. It doesn't sound like it's coming from the speakers--at least it isn't a system beep, but perhaps a hardware beep?
Any reason to be concerned about this?

No flashing light. I don't think it has to do with the RAM. And the beep occurs well after the startup anyways.
Funny though, it has been quiet for the past few hours. I'll keep posting updated if it starts to make noises again. Then hopefully I will be able to see if anything in particular brings back the beeps.

When I access Wealth Engine X My computer makes a high pitch whining sound. Why ?

When I log in to this website My computer makes a high pitch whining sound.
I also have this problem when surfing on Auto Surf Pro; and recently, while the auto surf was running, My computer shut off its
power, and I had to run the repair diagnostic to get it to start again.
I also have this problem with Empower Network with regard to the videos on there; and some of the videos "get" an "unable to load plugin" message when I try to open them.

Sounds like the drive although I suppose it could be fans if something is wrong with them. when my fans go into high performance mode they do not make this kind of noise. Are you also noticing more vibration when this occurs to the left of the trackpad where the hard drive is? About the only thing you can do is take it into the Apple store and have them look at it.
