How to enable sound when plugging/unplugging charger for laptop.

Q: How to enable sound when plugging/unplugging charger for laptop.

I was wondering if anyone is familiar with a method to enable sounds for when you plug in or remove a charger connected to your laptop. It is not a problem with my pc, but is an option that is not available for me which i would like to install to let me know if i accidentally unplugged the charger, particularly if I'm working on a full-screen feature. Any help would be appreciated.
I have Windows 7 home Premium 32-bit installed.

Preferred Solution: How to enable sound when plugging/unplugging charger for laptop.

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

A: How to enable sound when plugging/unplugging charger for laptop.

In the System Sounds, there is an option for device connect or disconnect. This will probably do what you want. You will have to assign a sound for those functions.

The System Sounds panel can be accessed from Start/Control Panel/Hardware and Sounds. Click on "Change System Sounds".

Hey guys I ran into a little problem recently and would like to share it I know it is supposedly ok to plug devices Plugging/unplugging sound 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 Plugging/unplugging sound devices 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 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 nbsp

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, coud've been just natural death of age, removing the plug at an extreme angle and damaging the jack, etc...

Is it safe to unplug my mouse and then plug it back in again into it's USB port without shutting down my laptop?

Is it safe to plug in my laptops power cord while my laptop is running without shutting down first?

A:Plugging in and Unplugging cords while laptop is running?

Yes and yes, except if you are going to unplug the power cord do it from the wall socket first and be sure you have plenty of charge on the battery.

I have a Dell Vostro running Vista Home Basic AC freezes and plugging laptop adapter when power unplugging 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 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 laptop freezes when plugging and unplugging AC power adapter with this problem I have not read a sensible solution yet My favorite laptop freezes when plugging and unplugging AC power adapter bad answer is quot don t unplug your laptop when it s on quot 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 nbsp

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

Hello! I have been looking online for websites where I can get help for my laptop. I have a Toshiba Satellite L55-C5272. I broke the screen, and replaced it. Then I had one other issue, every time I remove the charger from the laptop, my laptop automatically shuts down. Even with 100% battery. I dont' know what the cause of this is, but I do know I was not messing with the battery. This laptop is about 2 months old, and I don't know what else to do.

If you have any advice or suggestions, you may email me at [email protected]

A:Laptop shut down after plugging it to charger, cant turn it

Well you could try testing to see if it is the power cord or the battery first.

Try a different charger cord with the laptop and see if it works. If that doesn't do it, try a different battery.

Should that not work, then you may need to have it looked at to see if it is fixable, or needs replacing.

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.

Hi everyone, hope this is a good year for all. I just picked up a new computer running xp. It came without a floppy drive, so I picked up a portable external usb floppy drive. Is it ok to plug in, and unplug the floppy to the usb port with the computer on? Thanks for the tips/advice.

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,

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

Anyone has another idea?

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.

I have googled many solutions but nothing seems to work.

A:Simply unplugging my headphones and plugging them back in seemed to break them. HELP!

Do the speakers still work after you have unattached /reattached the mic?

Presuming you are running Windows (as you haven't specified)

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?

I went to start up my computer earlier and it would not boot up properly. Looking online someone mentioned it could be faulty memory. So one by one I took them out and started up the computer to see if it would boot with potentially removing a faulty memory stick. None of them seemed to be causing a problem so after installing all the memory back properly, neither of my monitors no longer receive a signal.

I recently bought a wireless 3G USB modem / hot spot. Although i use it primarily by plugging in my PC USB port, It just occurred to me that my smartphone charger also has a USB port. So i was wondering if i can use the modem by using the charger USB port or not. That way i will not have to keep my PC powered on all the time. My charger has a output rating of 5V and 830mA. I reckon there shouldn't be a problem but want to be sure lest i damage the modem.

EDIT: The title should read 'Power' instead of 'Charge'. Apologies for any confusion caused !!

I would like to be able to unplug my printer without having to 'safely remove hardware' first. Currently, if I don't do this, the printer is liable to be renamed the next time that it's plugged in, meaning that I have to determine the current incarnation via 'Devices and Printers' and then select the corresponding device in the dropdown. It didn't used to be like this!

I think the answer lies in some sort of performance boost... some sort of caching of data that Windows does before sending it all in one go... is it possible to disable this for this specific device, while retaining it for things which may benefit (USB flash drives?)?

Hi,My laptop won't hold a charge. I have replaced the battery and charger. The only time it works is when the charger is inserted into the laptop but even though it's plugged in it won't charge and will shut down immediately after the charger is removed. Please help.

Hi CJ777,
Thanks for reaching out with your query. You pretty much figured out all points of failure. Good job.
If the adapter is not detected in BIOS, it most likely is an issue with the mother board. In the BIOS set up, AC adapter should show up as 65w or 90w. If the adapter status is 'None' or 'Unknown Device Installed', it indicates that the mother board is not detecting the adapter for which the battery is not getting charged. Once the battery charge drains, I'm sure the adapter will not charge it again. Replacing the system board should resolve this issue.

yesterday I hooked up my PC to my home theter system and after unplugging it to put in my headphones the sound stopped working on either the earphones or the the stereo. Checked my sound devices and their drivers and went thru the XP troubleshooting menus and nothing is working. I am pretty certain that it is a hardware problem....could I have blown out the sound card in the same way you can blow out your speakers? Please let me know if anyone out there has any info.....

A:Unplugging USB sound bar or USB microphone causes playback problems

If the device is declared as the default and it's unplugged (removed from the system), it can no longer be the default and Windows will pick the default or clear the setting if no other device is present. In the Sound window, you can see that Windows will not allow a device that isn't plugged in to be set as the default device either--"Set as default" is greyed out.

Hello, I will be out of the country for about 12 days and I am thinking I should unplug my laptop (switch the powerstrip to OFF) while I'm away just to be on the safe side. I want to do this for peace of mind since I will be so far away. I have an old laptop that is running on 3 cylinders.

Upon return, will I be experiencing difficulty turning my computer back on? BTW, I am with CenturyLink Wireless.

I've not done this before as I've not been gone that long.

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 was watching a streaming video with low sound so I thought I would plug my earbuds in to hear better. I plugged it in and heard sound for a split second then nothing. I unplugged the buds only to find that there is no sound at all through the speakers now.

I have a laptop Dell Inspiron N5110. I "upgraded" to Windows 10 sometime in July, I believe.

I tried rebooting to see if that would fix the problem. Nope, it didn't work.

Any ideas or thoughts? Thanks

A:Plugging in headphones, now no sound at all!

Found the fix on another forum.

Here it is:

Check the Sound devices listing in the Device Manager. What is the status that is shown for IDT HD Audio? Does it show as working OK, or is there an error code (post the code).

If it shows working OK, RIGHT click on the IDT entry to highlight it and then LEFT click "Uninstall" DO NOT uninstall the drivers. Restart the PC and when Windows starts it will detect and reinstall the audio. This fixes any corruptions and hopefully will fix yours.

This fixed the problem though I don't know what caused it in the first place.

All is right in the world, again.

A mod can mark this issue as solved.

Hi all,

I have a curious problem, which I'm not able to solve on my own although I've a couple of solutions. Here is the problem:

When I plug my earphones in, its recognized that something is plugged in, the sound output changes, but I hear nothing through my earplugs.

I'm sure that: the hardware is working correctly (I have a dual OS system, and there everything is working fine). I have already reinstalled the drivers, reinstalled the HD Audio manager from Realtek including their drivers. One time, I had it working, but with the next reboot it did not work anymore.

In my sound settings everything seems OK, at least when it was working the same devices were listed and asssigned as standard devices so I dont think that the problem lies there. Anybody has an idea what to do or how to solve this?

A:No Sound From Speakers after plugging in bad Microphone

Hi WeeGee and welcome to TSF

On the recording your voice part, go to control panel and pick Sound and Audio Devices, pick Voice tab, under voice recording, pick volume. At this point, pick the options tab and make sure the Sterio mix is checked. This will add a control the the volume group that you will need for recording.

On the speakers not working after removing the head set. Note this, when you plug you headset in, the plug opens the contacts to your speakers so they will not work. When you unplug the headset, the switch contacts in the plugin port is supposed to make contact, thus restoring volume etc back to your normal system. Try pluging and unplugging the headset to get that part working again.

Be sure that you are using some sort of recording software to get the recording to work. Windows has a short one that you can use, or other recording software might be needed for long samples.

Hope this works for you,

A:No Sound - Have to keep re-plugging in speaker connector

The AMD High definition Audio Device is audio from the Video card for HDMI Audio.
Bluetooth audio device is what it is some Bluetooth attached audio device
High definition audio device is your PC's sound device, but is not the correct sound driver.
Intel Display Audio is the Intel HDMI audio from your i7 CPU.

First the High Definition Audio Device, that is the generic basic function sound driver installed by Windows. You need to install the correct sound driver (which may fix your problem). Go to ASUS downloads for your motherboard and get the correct sound driver (could be RealTek, IDT, etc).

Second, the Bluetooth may be interfering. After you get the correct sound driver installed, if you are still having problems, disable the Bluetooth see if it is interfering.

Third, normally you do not have both the internal CPU video and a separate video card enabled. Most BIOS will auto detect and if there is a separate video card installed it will select that and disable the other. However, this is probably not the problem.

Why when i put on my laptop charger laptop goes up to 80 degrees celicus It gets really hot but when i take it off it goes down

A:When putting in laptop charger, laptop goes up to 80 degrees celcius

Thats because the system "steps down" the CPU, GPU, Display brightness among other thing when the computer is running on batteries. With some tweaking you can make it run at 80 degrees all the time, but your battery wont last long. You may also notice it responds a bit better when running on mains. With regards to getting it to run cooler on mains. I have never really tried tuning a computer the other way but someone here may be able to advise. I was expecting to see AMD CPU in your specs and I would in that case say it was normal. Other than that you may have high levels of dust build-up or failed fans inside. If you know someone experienced with laptop repair you could get them to take a look and give it a clean out.

I'm rather rusty with working with computers, and I'm not even sure if this is right place for this, but I recently got a new Gateway T-6836 laptop which runs on Vista (64-bit). I noticed that while I have my computer on, if I unplug the AC adapter to move to another location and I plug the AC adapter back in, everything freezes. I can't even get the mouse to move and there even is no response that the caps lock is on. I end up having to force the laptop to power off.

There seems to be no problem when I unplug and plug back in the laptop while it is off.

Any ideas? Any help would be appreciated!

A:Laptop freezes after plugging in AC adapter

I would just suggest you don't unplug your system from an electrical outlet while on unless you eventually want to purchase a new system. That's just a common sense approach. I would imagine it would freeze up under those circumstances. You need to make sure the system is off before you try the plug n play with your PSU. Jazz

A:Sound not working unless i disable and the enable sound card

If only a few months old it may have a defect. Normally parts should last for years and not change in a few months.Still, to eliminate a possible software issue, use the system restore to go back to a earlier time. Try two days back, then four days and so on until you find the critical point where something was changed.IMO you must report this to Dell as soon as possible.,152257.0.html

For the past few days, if I connect my earphone(3.5mm audio jack) when some video is being played, be it in Facebook or YouTube or in the vlc media player
1. The laptop starts hanging. The video that is being played breaks, the system becomes extremely slow, can not even move the cursor.
2. The internet is disconnected (i.e.) I use the WiFi, in the notification bar at the bottom, it simply is disconnected. The WiFi icon only has a red 'X', and no WiFi network is shown, even though my WiFi is switched.
3. I have to restart the machine to use it normally
But if the video is not playing, and I connect the audio jack, nothing happens.
Has any one happened to have had such an issue ? Or can anyone suggest how do I start with identifying the root cause ? Please suggest. Thanks in advance.

My laptop recently crashed and it is not possible to install an operating system onto it without re-formatting (Believe me i've tried everything possible). Is it possible to plug the laptop hard disk drive into my main computer and retrieve the data from it this way? Or would it blow the drive? What do I need to do in order to plug it in and retrieve the data? I have no idea how to do this, so I have turned to you guys. Please help, I will not proceed until I get a reply, I'm really scared lol.
Cheers guys,

Hello everyone,
I'd like to know how (if possible) to make it so that my laptop does not automatically change screen brightness when plugging in or unplugging.

You see, there is a brightness setting that is saved for plugged in and unplugged, and when you change between plugged in and unplugged it reverts the screen brightness to that saved level.

For example if you have it unplugged and you set the screen brightness to 100% then plug it in, it saves the unplugged screen brightness to 100%. Now when you're plugged in you change it to minimal brightness. Later when you unplug and leave the screen brightness will revert back to 100%.

I'd like to disable this automatic screen brightness change.
Thanks for reading.

A:Stop laptop from changing screen brightness when plugging in

Which OS are you on? Say you were on Windows 7 there is a setting to change the brightness, but some laptops don't work with these settings.

Hello, I have a Y510P notebook and I am having some problems with it. Once I was playing on this laptop and it suddenly it turned off. The power cord would make a weird noise and it wouldn't turn on. After a while it started to work normally. It was probably a high voltage spike in my house, since we already lost a cellphone. After that I notice that the laptop would turn off, as soon as I plugged the power cord. I ordered a new power cord and battery, but this issue is still happening. Anyone has an idea? Thank you!

A:Plugging power cord turns laptop off (Y510P)

Hi Tiagoramosleite,
Welcome to the Community Forums. 
You can initially start isolating the issue using the power checkout guideline (page 21). 
Try to notice anything on the DC port like bent pin , unusual appearance / marks or smell of burnt . 
Would any led status light (page30) still be lit when plugged in. 
It would be best to have it further checked for further isolation for dc in port issue against failure on the systemboard itself with nearest service center or call in technical support for further recommendation. 
Update us how it works best for you.

I bought a dell laptop and it doesn't have the power cord with it, and I cant even find anything on the laptop to tell me what model it is. It wont power on and there is not a service tag or express tag sticker on it anywhere. How can I determine what model it is and what power cord I need to buy?  Thanks in advance.

Hello, my lenovo charger broke. It charges but the wire has to be in an angle and if I move it stops charging.
I have a second charger for laptop. The charging port fits in perfect.

Here is the specs of my charger
Output 20V - 3.25 A

Specs of other charger (Really old Toshiba ~ 2007)
Output 19V - 6.3 A

A:Using a different charger for laptop?

When considering non-original laptop chargers, the voltage needs to match exactly while the current needs to be equal to the original or higher. In your case the current rating for the other charger is fine but the voltage is not correct. It's possible that the laptop has a voltage regulator inside to compensate for the lower voltage but since I have no knowledge of the inner workings of your Lenovo, I can't say whether the 19V is close enough.

tell me what's my laptop probleming ?

A:HP laptop and it has been not on because of bed charger

Welcome to the forum!

Obvious answer is you fried the power input circuit using too high a voltage. Please tell me it was an accident and you didn't use the 30v power supply on purpose.

On my laptop i have a problem with the charging port at the back of it. the port which connects the charger to my battery had been playing up and will not kepp my charger in place and won't charge up, any advice on what i should do?

I have a laptop in which the charger 'pin' (to plug into laptop) seems bad. It's a bit loose when I wiggle it and when in the laptop, the cord has to be positioned just right for it to charge (it seems to lean the pin to where it can charge). I'm not sure if it's the charger or the port.

The charger (call it #1) is 19V, 2.37a, 45w. I have another charger (#2) (same brand laptop, different, lesser model). The voltage specs are 19v, 1.75a, 33w.

Can I safely use charger #2 to verify weather the problem is the charger or the port for charger #1's laptop?

A:Laptop charger

If the connector from charger #2 fits correctly into the laptop in question, then yes, you can use it for troubleshooting the problem.

Whenever I plug my adapter into my laptop the CPU goes straight to 95-100% and stays on it but when I take it out it goes back to normal.

Also, It is a newer charger and it takes way longer to charge the laptop fully.

A:Laptop Charger

Is this "newer charger" the battery charging circuit in your laptop or do you actually mean the power supply (AC power cord and AC to DC adapter)? If the former, did you have the work done and do you have a warranty? If the latter I suspect you got the wrong power supply.

A:laptop charger help

...It's a Dell.
On that same screen it should say how to disable that message. Sometimes you have to update the BIOS to actual be able to get rid of that message or be able to use non-Dell adapters. Latest BIOS is here:

But if its not charging the battery then there could actually be an issue. Possibly with the charging circuits on the mainboard, or there's possibly something damaging the adapters, like brownouts or surges. Does the jack in the laptop seem loose?

Hello guys,

Since yesterday i'm facing a strange issue.. Whenever i plug in my laptop to charge, it just automatically turns off (not proper shutdown) within a few moments. This duration before power off varies at times. Its runs without any problem when on safe made. This problem happens only when win 7 is in normal mode. I noticed that the fan speed increases as i plug in. However, this also used to happen earlier. On searching online, some said it may be due to heating issue. But then how does it work normally in safe mode? Also, when i start in Diagnostic Start up mode, it starts perfectly. It does not start when i remove my battery and plug powers off just after entering windows. This problem does not occur when in BIOS. Please help in finding a suitable solution.

Thank you.

A:Laptop turns off when plugging in for charging in normal mode on win7

Post make & model in case this is a "known issue" that can be google-searched for.

By "normal" mode, do you mean not "safe mode", or not "selective startup/msconfig"?

Does the problem also happen in safe mode?
Does the problem also happen in Selective Startup?

Otherwise, what do you mean by "normal".

One guess is that you have a problem with a 3rd party power management software. It's supposed to start "doing something" (such as report the battery status) when it senses a power plug is inserted, but instead it shuts down.

Is the shut down orderly (Windows is shutting down), or is it abrupt, like someone suddenly killed the power?

What's most interesting so far is the possibility that the machine works & charges fine in Safe Mode, but not in MSCONFIG or Normal mode. If that's the case, we're looking for a software problem that can probably be solved by reinstalling something, compared to a hardware problem which can be serious, expensive and/or insolvable.

I am looking to buy a universal laptop charger for my Sony Vaio Flip 14A. I just wanted to get some opinions on whether these are normally safe and if there are any risks associated with buying these?

The original spec of my charger is

while the one I am looking to buy is here

My main concern is that while my laptop charger shown output 19.5V = 2.3A, the universal one shows 19.5V = 4.7A. I wonder if this can be an issue?

Would appreciate some opinions.

My hp pavilion g6-1c31nr overheats and shuts down every once in a while when plugged in to the charger and on.  I do game on it at times but i also study on it as well.  last check when i booted it up after the last incident it was around 170F.  when i plug it in temp apparently spikes but when i am running on battery it stays lower than plugged in.  the charger when you put it to your ear does put off a bit of a high pitched whine though so do i need to replace the charger?
