Annoying beep when plugging/unplugging AC Power

Q: Annoying beep when plugging/unplugging AC Power

Hi all,

Acer 7740g, Windows 7 HE.
I have this annoying problem that when my AC power is plugged or unplugged it makes a beep.
Muting the sound completely helps, but that's sometimes not an option.

I tried the following and no luck:

Editing a registry entry HKEY_CURRENT_USER\Control Panel\Sound\Beep and changed it to "No".
Uninstalling the Beep device from my device manager.
Turning off my pc speaker, unfortunately, I didn't find where I can disable it.

My sound card drivers are: Realtek 6.0.1.5969

Anyone has another idea?

Thanks.

Hi All! Been a while since I've posted, but sitting here reading other's posts, I almost forgot why I logged in!

I have a weird problem with my computer.....a little background:
I didn't turn the computer on for a LONG time....perhaps a year, so one day, I decided to boot it up and it won't boot past the post! So I replaced the MB battery, checked the power supply, replaced the memory...and it booted. But then, I turn it off, and it won't boot again...same problem with it not booting past the mem. post. So being that it was an old computer, I figured I'd just build myself a new machine and use the hard drive as a slave. There are programs on the drive that I want to use that I cannot replace! Well, I tried doing that, but the new computer won't see the drive....it won't even boot with it plugged in. So....

I take the hard drive to another machine that I know works fine, and it boots. Problem solved....so I thought. I turn it off, and try and turn it back on.....nothing.....no beeps, no post....nothing. So I tried changing the power supply, and plug all back in, and it boots. Turn it off, nothing. Long story short, if I unplug the motherboard power cord from the board, and plug it back in, it boots, but if I turn it off, I have to repeat the motherboard plug thing to get it to boot again. I have had the drive checked for viruses, and it's clean.
I have to admit, I am stumped! Any ideas? Any suggestions would be greatly appreciat... Read more

I have a Dell Vostro 1400 running Vista Home Basic and have had two periods in the laptop's existence where it would mysteriously freeze. You could see everything on the screen, and the power lights were on, but it would not respond except to a hard reboot by holding the power butting down for 5 seconds.

I am going through one of those periods now, and have discovered that the problem happens when I am either plugging or unplugging the AC power adapter, but don't know why. I have been all over the web for a solution, and while it does seem I am not alone with this problem, I have not read a sensible solution yet. My favorite bad answer is "don't unplug your laptop when it's on."

So, does anyone know what it could be? I wanted to look at system logs, and so went into the Event Viewer not even sure what to look for, but didn't see anything that looked like a likely culprit. Please help!

Thanks,
Neil
 

A:laptop freezes when plugging and unplugging AC power adapter

being a member of the Dell Community Forum, I looked there and found this

A lot things happen in Windows when inserting the AC power adapter.

To check if it's a classic CPU lock-up: repeatedly press capslock. If the capslock light doesn't change, there's no live in there.

Assuming the CPU is locked up: It's possible there's a log entry in the system log just before the AC power adapter is inserted. These entries give clues where to look, just before things went sour.

Next try to reproduce it in Safe Mode (press F8 when Windows start) If it's also in Safe Mode - try running an alternative OS (no need to install)

If the problem also shows up here - most likely it's a hardware issue.

Otherwise it's a windows issue - might be driver related.

the "alternate OS thing is a link on the forum web site. Click here to go to that site.

Hope this is some help... Raybro

When plugging in or unpluggingthe power cable the system directly jumps into Blue Screen (BSOD). I used a small tool to extract the basic dump message: RESOURCE_NOW_OWNED I installed the newest versions of LENOVO Solution Center, LENOVO Energy Management, ...I did an BIOS update longer ago, but I'm not sure, if there was a time-based relation to my problems. The BSOD occurs when: * Laptop started with power cable => Power unplugged* Laptop started without power cable => Power plugged* Laptop in sleep mode => Power plugged and Laptop started again lifting screen* Bring Laptop in sleep mode => Power plugged Does anybode had this problem. Before every meeting now I have to shutdown and restartthe engine... I'm not sure, if the Windows repair CD could detect and repair such a problem.Thanks in advanceKlaus Wegener

Getting ready to do the install on my new SSD with some trepidation. I have Raptors in Raid 0 right now and would like to simply unplug them, set the BIOS to AHCI and use the 0 port for the SSD experiment/potential fiasco. What I hope to be able to do if the SSD doesn't like me, is to unplug it, set the BIOS back to Raid, plug in the Raptors and pretend the whole thing never happened. Does this stand a chance of working?

A:Plugging and Unplugging!

I wouldnt unplug the raptor raid - if you use intel raid (the one i'm sure of and probably similar, or the same for others) when you enable raid in the bios it also enables AHCI - so you should be good to go with testing the ssd drive - just unplugging a raid array can be very hard to set up again - i did it years ago and it was a miracle i got it back up and going again (that included reinstalling the OS) so not recommended - it also depends what options are available in the raid rom (i think its called) which you set it up in before you install the OS. From memory, which is bad, the problem was it couldnt recognise one or both the drives.
It depends on your motherboard I guess but for mind it should be ok - running raid and using the same controller to use a ssd drive in AHCI mode - but treat this as my opinion - you should be able to find information on your motherboards site, or intel etc's, site. Or wait for more replies as Im uncertain and more repies means more suggestions.
If it has 2 controllers eg intel and jmicron use the JMICRON if it supports AHCI to be on the safe side.

Hey guys. I ran into a little problem recently, and would like to share it.
I know it is supposedly ok to plug USB cables in and out while the computer is on, but, to be safe I have always gone through the Safely Remove Hardware icon.
For some reason, though, I have always felt it is safe to just plug sound devices in and out with no regard to whether the computer is on or not. Have done this for years.
However, I noticed a few days ago that one channel of my onboard sound line input had quit, on my newest MB. I did not realize this for awhile, because somehow the system had just rerouted the one channel into both sides, when writing to the CD or DVD. (I noticed that Joe Walsh appeared to be playing an unplugged guitar on the Eagles Hell Freezes Over concert after transferring from my old VHS tape to DVD, even though both speakers were working! LOL)
Anyway...I fixed the problem by just installing a sound card. (by the way, even a cheap $14.00 sound card is at least as good as most onboard sound: mine sounds much better than the original.)
So, would you guys advise having the computer turned off, even to plug in headphones, for instance?
 

A:Plugging/unplugging sound devices

No, 1/8" jacks can freely be plugged/unplugged while the computer is on, and when you're outputting sound.
As to why the jack went dead, cou÷d've been just natural death of age, removing the plug at an extreme angle and damaging the jack, etc...

My problem is this, my motherboard is Biostar TP67B and I have downloaded the sound drivers from the manufacturer website which is realtek high definition audio.However, If i had left my headphone plugged into my front panel jack and when I restart my computer, the headphone icon keeps flickering saying its plugged and unplugged constantly when it is in fact plugged in. I had tinker around a little bit and I have no idea how to fix this problem now. Its going bad to worse as it unplugs itself randomly now. I'm trying to go for a full reinstall of my sound drivers.

A:Headphones Plugging and Unplugging constantly bug

Have you tried a different headphone? Maybe the headphone and not the PC or headphone jack.

If not the headphone, check the connection from the front panel at the motherboard, May be a bad connection there. Reseat (unplug then plug back in) the connector at the motherboard. If it still has problems I would suspect the front panel headphone jack, or the wiring.

Hi all,

I'm at a dorm room with cable internet. It usually works fine, but now if I unplug it, then plug it back, the computer doesn't connect to the internet anymore. Sometimes it says it's acquiring network address, but that doesn't change. The computer connects to the internet fine if I turned on the computer with the cable already plugged in.

Another computer doesn't have this problem with the same cable, always able to connect after being unplugged/plugged. Both computers are on Win XP.

I suspect the Windows firewall has something to do with it, if only because it is turned on the the problematic computer, and not on the other one. I couldn't turn it off, however, because it doesn't let me open up Windows Firewall Settings, giving me the message that the "associated service is not running" and whether or not I could like to start it. If I click "Yes", it simply says it "cannot open Windows Firewall/Internet Connection Sharing service".

Please let me know what the problem might be and what i can try to get it working again. I hope I haven't given too much useless information.. haha. Thanks!

Dave

Hello, I've noticed that my computer crashes everytime i unplug or i plug in and USB drive. Today I bought a new USB mouse and when I connected it no crashes were seen, but when my pc installed the last driver, the BSoD appeared once again. I'm using Win7 64b and I really don't know what can I do, I've tried everything like uninstalling all USB drivers and recreate the INFCACHE.1 file, but still nothing. What can I do to solve this?
Thanks in advance.

A:BSoD when plugging/unplugging USB and when installing USB drivers

1) Does it happen with all usb devices or only the mouse?
 
2) Does it happen with all usb ports?
 
3) Does it happen in safe mode?
 
4) Look in device manager - are there any yellow or red symblos?
 
5) Download and install the newest chipset driver for your system. If it's a laptop, get it from the website of your laptop manufacturer. If it's a desktop, you can get it from either the desktop or the mobo manufacturer's website.
 
6) Look for a bios update.

Hi DNGUYEN2252,
Are you using an original Dell OEM Adapter? When you plug in the adapter to the system, does the adapter stay firm or does it fall off easily? Is the adapter frayed? Is there any damage on the system?
Does the adapter led stay on and stable or does it go off when connected to the system?
Disconnect the adapter and battery and press and hold the power button for 30 seconds to release any static power. Then try connecting with the adapter only / battery only.
I would first suggest you to try with another power adapter. The current one in use might be shorting the system and hence the system powers off.
If another adapter works fine, then replace the adapter. If the other adapter  also exhibits the same behavior, then replace the DC port - this is the part you would need - http://bit.ly/2kZR8go
If nothing works, I would suspect a faulty motherboard. 
If there is no warranty, then you could contact our team to get a quote for a paid service call - http://dell.to/1vnT6CQ
Also, please click my DELL-username and write me a private conversation with the service tag and your contact details(Name and Email) for case records.

Open control panel, then open Sound (depending on your OS and view options you may need to click on the Hardware and Sound option first or similar)

In the sound window, click on the Recording tab.

With the Mic attached how many devices do you see?

Is the Mic on your headset set as Default?

If you remove the mic and reattach (with the sound window open) does the mic get recognised and show back up in this list?

Does it remain as default / enabled?

Urgh. Typical.

Install new case fans after moving 2 HD cages from the front of Corsar 600T case.
Check they run ok. Fine.
Put HD cages back in, one in the space on the bottom of the case beside the PSU.
Fight with the cables to get the HDs connected and the modular PSU cables back into the PSU.

- Attempt to power on. Nothing.
- Check cable, try another power cable. Nothing.
- No fans, no lights, nothing.
- No 'electrical sound' when flipping the switch on the back of the PSU.

Seems I have a 7 year warrant on the PSU and its only about 3 years old. But Corsair RMA system insists that you "try another PSU to verify the problem is the PSU" which is fair enough so off to buy another PSU, probably another Corsair. Hope the RMA system allows for refund rather than replacement, otherwise I'll have 2 PSUs which isn't really much use. I guess I can use this as an opportunity to upgrade to a bigger PSU since 7970 CF, 3 HD, 2 SSD, i7 2600K @ 4.7Ghz, a powered device connected to almost every single USB port is probably getting towards it's limits. I can then stick any replacement HX750 on Ebay or something...

Hi,
My laptop here is a Dell Inspiron 15, 3000 series. 
The laptop itself works perfectly fine, I am able to get into windows (which I installed myself, it originally came with Ubuntu). 
Occasionally though, it will do a BEEP BEEP BEEP PAUSE BEEP BEEP BEEP PAUSE (repeats).
This happens on boot and sometimes when I am using it. Sometimes it turns off suddenly when I am shifting the computer around. It's extremely loud.

What is causing this? The sound seems to be coming from around the area the Memory banks are under the laptop, but nothing seems to suggest that anything is wrong.
I took a suggestion and used FN+Power to do Hardware Diagnostics which said nothing is wrong.

What else can I try?

Remove the battery from the computer.
Press and hold down the power button for 15 seconds.
Then connect back all the peripherals and check if the beep pattern repeats and reply us with the beep count.

I'm having a bizarre issue where simply unplugging the official Lenovo power supply from the orange USB power port causes the laptop to immediately issue the subject warning, along with the detail "A USB device has malfunctioned and exceeded the power limits of its hub port".   This warning pops up every 5 seconds, unless clicked on, where reset/close options do nothing.  Crazy thing is, NOTHING is plugged into any USB port!   Reattaching the power supply does not clear the error.  Only rebooting with the power supply cable connected clears the error.   Remove the power cable, and the error instantly comes back.   All of the USB ports actually work fine, including the USB C port, whether or not this message is active. Maybe it is a hardware issue, but ALL the USB ports actually work fine.  I can't figure how unpluging the power source can trigger a USB power surge when nothing is actually connected and the battery is fully charged.  I've removed/reinstalled the USB Root hub, eXtensible Host Controller, Generic USB Hub, etc., drivers multiple times to no avail.   No errors with any devices are apparent in the device manager. I've seen a lot of issues reported about USB power surges but none like mine.   Anyone have any ideas about this?  System: Lenovo Yoga 900/16GB/Windows 10

I've had Win7 for a few months now (thanks to MSDN Academic Alliance) but I've just recently started having this problem. I'm running Win7 Professional on my HP HDX16 laptop. My laptop basically runs flawless when plugged into AC power. When I unplug it, however, CPU usage skyrockets to 95%-100%. I managed to look at the task manager one time at noticed that it isn't necessarily one process that is crippling my computer; It's more like 4 or 5 programs that run around 20 CPU and the rest of the processor is used by various other programs. The process hogging programs vary sometimes, but it usually includes audiodg (audio device graph), mcshield (Mcafee), and a few other svchost (usually Win Defender, Win Firewall and AudioEndpointBuilder). I have the IDT HD audio card for those wondering (and all of the latest drivers from HP). Does anyone have any ideas as to how I can fix this?

A:Windows 7: 100% CPU Usage After Unplugging AC Power

This is Windows 7 switching to battery mode and the power saving parts of those programs are being turned on. Because they are trusted services they get CPU priority
If you find this CPU overload a nuisance, switch power mode from power saver option (type 'power mode' into run box found from start button to get quick link to power options)

Unplugging the power causes the system to crash.
This is especially bad with a slippery power plug.

I'd be immensely thankful for tips on getting the latest drivers.
I haven't figured out why Intel's utility for detecting my system (Intel? Driver Update Utility) won't work for me.
HP's Support Assistant doesn't install, and they don't show the latest drivers on their support pages.
Identifying the motherboard or chipset, and locating their drivers have been especially tricky for me.

The OS is the same core as Windows 8.1 Update, so it belongs here.

A:Unplugging power crashes system

Did the system come with Win8/8.1 installed on it?
What sort of error do you get when trying to install HP Support Assistant?
I have issues with the Intel utility also, I chalk it up to it only being accurate on actual Intel systems.

You can manually download the drivers from HP if you visit the support site for your system.
Please be sure to update the UEFI/BIOS using the inside Windows installer.

Only 7 Windows Updates installed. Most systems have 170 to 190 or more. Please visit Windows Update and get ALL available updates (it may take several trips to get them all).

Don't worry about the specific number, it's just important that you have checked and installed any updates that were available (and didn't experience any errors).

After the system is fully updated, try to install the HP Support Assistant again.
If you get it installed, make sure to run it and install ALL available updates.

If the system continues to BSOD after it's fully updated, then please run Driver Verifier according to these instructions: Driver Verifier Settings

Hi Tech forum,

So i have a pretty puzzling issue that's been skin-peelingly fustrating to fix. I have an Acer Aspire 5552g laptop with a newly installed motherboard and ram that works perfectly fine with the AC adapter. However, once i unplug the AC adapter, the laptop shuts off with 10-20 minutes of usage. And it's not a normal shut-down. It freezes for a good 2-3 seconds, the fan kicks in, and does a hard shut off. No warning or anything. I made sure the connections where correct when installing the new mobo, per manual instructions (and some visual help on youtube) and it definitely does not overheat. I check temps constantly for any anomalies.
But it still shuts off when it is not using direct power supply from the AC adapter.
I figured the original battery was defective, so i purchased a new battery from acer that came in a few days ago and it's still happening on this new battery.

I flashed the bios with a current version from acer support site. I tried taking the battery out and holding the power button for 20 seconds to discharge whatever any currents that may be stuck i guess (read it somewhere on a forum). BTW the OS is windows 8 pro (clean install and updated drivers). I also have windows 7 home premium installed (dual boot/ with updated drivers as well) to see if the problem persists there as well, and it does. I figured maybe these windows OS's have problems so i tried booting a disk image of Ubuntu and it also does the same problem here too.

I have a Toshiba Satellite L650 that is almost two years old. About a month ago the laptop started shutting off immediately after the power cord was disconnected. I have since bought two new batteries and one power cord to see if either of those items were causing the problem but it still keeps shutting off. Any suggestions? THANKS!!!

I started to notice two days ago that my computer performs a beep which carries on until I turn the computer off during I'm using the computer. Although I don't think that it's a very serious problem - it's damn annoying.
Does anyone have any idea what is causing it and how I can disable it?

My laptop suddenly started beeping this morning (it was fine before), occasionally once, sometimes twice(one long beep, two short beeps - not together; almost random). I tried system restore because it worked for me when it happened to me before; now it won't stop beeping, usually when playing games. Nothing happens though; I keep expecting it to crash but so far it hasn't. It's just that annoying random beeping. How do I turn it off? I was also wondering if it's a hardware failure or if it could be caused by a virus?

Whenever I'm in an msn convo and hit backspace until the end of the text, when it hits blank it beeps. It's annoying. I'm not supposed to have any sound, I disabled all alerts or alarms or whatever... It doesn't sound like it's a set sound though, sounds to me like a default machine sound. And it's as loud as however high my volume is at that moment...

Anyone help ? It's probably real simple, I just don't know puters enough
 

A:Annoying beep I want to get rid of

this sound is the one used when your PC boots, too right?

if so, this sound cannot be "not" used. if you have disabled the Microsoft Alerter service, you MIGHT not hear this, but as disabling this service will cripple you to error messages as well as error sounds, you are wiser NOT to disable it.

the sound scheme "No Sounds" should also disable the majority of the usage of this beep. to turn system sounds off, you CAN go to the control panel, click Sounds Speech and Audio Devices, and in the Sounds Tab, pull the box down to see NoSounds as a soundscheme.

Have run Office 2000 for years with no problems. Now installed on new laptop running Vista and everytime I open a document in any of the Office applications, it beeps at me! Any ideas how to stop it? I've turned off all the sounds but this one still escapes. Also, when I try to send documents as e-mail attachments direct from Word or Excel, it doesn't send it as a Word or Excel document but as something which no-one can open.

Bring back XP (and I didn't think much of that either!)

Mute the sound . What you may have to do it turn off the sound in the control panel of that program.

hey Everybody,

Here's something that's been grinding my friend's gears for some time. He's got an E-machines desktop which starts up with this loud annoying beep. We share an appartment and I can always tell when he boots it up :]

The only solution that I've found so far, was... to disconnect speakers and reconnect after the PC speaker does the darn noise. The thing is, I don't like that kind of approach and so does my friend.

Does anyone know how can we turn it off? Is there some hidden BIOS setting that controls it?

thanx,
kay

just after I start up my computer, and I press the control "Ctrl" button it makes an annoying beep. I think some other buttons might trigger other beeps like the Shift key. it seems to happen if I press ctrl just after start up.

i run a fujitsu with windows vista. i have heard people in some of my college lectures have the same problem across the hall, making the same beeps after they start up their computers before class and press one of these trigger buttons (control, shift, etc). it is annoying and it sounds like a 1980s crappy computer beep sound.
