Hi, just bought the 2-1 laptop last week. I want to enable a notification sound while plugging in the charger and also when I'm unplugging it. I've checked the device sound properties but don't seem to find it. Please help ! vsen

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.

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".

Just noticed this whenever I plug or unplug the charger. The laptop lags for 1-2 seconds before returning to normal. This is noticeable when playing games or watching videos. Haven't seen any abnormal drops or spikes with the temperature of the CPU, GPU and HDD which would suggest a hardware issue. Tried doing this while running 3DBenchmark, and there is a huge drop in FPS, from 130-200fps down to almost 16fps esp. when unplugging the charger.Is this normal?

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.

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.

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...

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!

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.

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 the Hyperx Cloud and the microphone easily unplugs from the headphones so that you can choose to not have a mic some times. While I was talking with my friends on skype and needed to mute the mic quickly so I just pulled out the microphone and when i plugged it back in it didn't work. 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 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,

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

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.

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.

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...

First of all, thank you very much for all your previous help. I'm back with more difficulties. 
 
My laptop (HP Envy dv7) recently forced a Windows 8.1 update. Ever since, whenever I plug or unplug the charger, the screen goes black for a second or two. Troubleshooting didn't fix it? Help is much appreciated.

A:Temporary black screen (un)plugging charger

That means your display driver is not usable for windows 8 and windows 8.1. I would advise you to download and install Windows 7 display driver in compatibility mode and review if it helps.
There are few steps to set up window 7 display driver
 
Install & download display driver
Right click on the driver & go the properties
Select compatibility’ tab and test the box "Run this program in compatibility mode for” and click Windows 7 operating system from the drop down.
Finally click on button ”apply” then “ok” and run the file to install it

The past few days, my laptop has been freezing after about 20 minutes (lately the amount of time has been decreasing to now about 15 minutes). First it would only freeze if it went idle but now it's freezing randomly. It would only freeze when I plug in my charger.

I replaced my adapter to see if that was the problem, but it wasn't. I also tried changing my set up so that my computer wouldn't sleep but still, it would freeze. I also launched CCleaner to try and clean up my registry and though it did fix up some problems, yes once again, my laptop would freeze.

I installed several anti-virus/malware programs as well but none of them seemed to work. They wouldn't detect anything through quick scan but once I try full scan, it would freeze. I tried going into safe mode, but before making it in, my laptop would stop and go into regular mode. And just a few minutes ago, I got the blue screen of death.

Please help!

A:My laptop freezes 10-20 minutes after plugging in my charger.

Make sure the charger has same specs as original factory one.

I recently bought a new Dell XPS 15 9550 laptop. Whenever I plug in the charger to charge the laptop, the IMDb webpage of the movie "Don't Breathe" opens. This only happens once, i.e. when I plug the charger for the first time and not after that. It's a really bizarre problem, which I am not understanding. Can someone else please shed a light on this?

You'll want to give the system a deep scan with a malware removed - the free version of malwarebytes will clean up the system just fine.

Hi, my new Acer V Nitro laptop makes a short, beep tone (coming from the speakers) when I plug and unplug the charger. I have read online that it is due to the driver and/or BIOS and I have done everything to disable it (installing new driver, searching for options in sound menu of Windows, going into the BIOS settings...). Finally, I have found the solution: deactivating the autostart of Realtek Audio driver on Windows start. Do you think that it is normal to hear this tone? I have completely reinstalled Windows and the tone finally reappeared (only after installing all updates). Thanks, 

A:Beep tone when plugging the charger - Acer V Nitro...

Hi, Well it makes a beep to tell you that the charger has been plugged in. Nothing wrong with this. It makes the same beep when you unplug the charger. It is normal, and it is implemented on more acer notebooks, not just yours.

Product number: D1C68UA#ABA Serial number: CND3130F7F Hello, I am having trouble with my wifi connectivity. I've noticed that my wifi connection is generally much stronger and stable when I am not plugged into the the power cord. When I plug in my power cord to charge my battery, My wifi signal always loses strength, and most times loses connection. If i unplug the cable once more, the wifi signal will regain strength. I've updated my drivers, reinstalled a couple as well. I've also changed my power options for the Wireless Adapater Settings to Maximum Performance. Still this problem remains. Please help.

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 !!

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.

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.

As long as the power cable is plugged in in my notebook the brightness of my display is fine.

But when I plug it out and use the battery the brightness becomes suddenly darker.

Why?

How can I prevent this switch-to-dark-screen?

I found no corresponding option in the power plans

A:Notebook display brightness low when plugging out power cable?

Try going to the Power options and then click Change plan settings for your power plan then in the next window under battery at the bottom is a adjustment for brightness. Be sure to save changes one done.

My Dell Inspiron 17R 5720 doesn't recognize charger any more. And unfortunately my warranty expired 2 month ago.It was plugged in and working in the morning, but then in the afternoon I noticed that it was running on the battery only. It wont start without battery (just charger plugged in).
1. So here what I have done to debug. Me and my brother, we have purchased the same Dell laptops at the same time a year and a bit ago. This is why for a debugging purposes it was good.I took my charger and plugged in to his computer. And it works. Definitely not the charger issue I guess. And when I plug charger in to my computer, green light is still on the charger. And I have the original charger that came with the laptop.
2. Now, laptop works on the battery only, so this means that motherboard is working. I guess.
3. Next thing I did was unplugged charger and removed the battery from the laptop. Then I pushed and hold "Power" button for 45 seconds to discharge a flea charge. Plugged charger back in but laptop wont start.
4. Next I started laptop on the battery, went to BIOS and checked if the charger is recognized in the BIOS. No, it doesn't recognize charger. So, if it is not a charger then what else can it be?
5. Laptop doesn't have any strange smells so I'm not sure if anything happened with the motherboard, but I would assume mother board is ok because it works of the battery.
6. I was thinking updating the BIOS, but I can't, because it wont update whi... Read more

A:Dell Inspiron 17R 5720 doesn't work with charger. Charger is not recognized. Not charger problem.

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.
