laptop freezes when plugging and unplugging AC power adapter

Q: laptop freezes when plugging and unplugging AC power adapter

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

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

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

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

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

Hi Experts, I have a serious problem using my W520 since a few month. 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

A:Laptop turning off when plugging or unplugging in charging cord

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.

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.

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".

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.

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!

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...

Condition 2 - " When music playing out of speakers also at sometimes can hear crackling noise coming" ( like speakers can't handle the frequency properly)
Condition3 major one -  "At the time of plugging in power supply in or out of laptop."                                                                                                                                                When video/audio/u-tube playing I can hear  short crackling noise&nbs...

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.

Greetings everyone,
Im not too tech savvy so I will try and explain exactly happened and hopefully get some assistance. I have an HP G42 AMD Turion II Dual Core Notebook that I am using for school (had the laptop for a year now, Windows 7 installed). I use it for watching movies (using GOP player), listening to music (itunes), completing term papers and attending online courses. I recently purchased an HDMI cable to watch movies from my laptop to my tv (I have an old Hitachi CRT 1080p w/HDMI compatibility), and when I plugged the cable in my laptop screen turned black for a brief moment, resumed normal and then completely froze. The only thing I was able to do was power it off and attempt to restart. I tried to restart the laptop and was barely able to type in my password as the welcome screen before it froze again. I can run windows in safe mode (both network and cmd prompt) but I cant run in normal. If more information is needed to troubleshoot I will be more than happy to provide. Thank you for your help!!!!

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!

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.
 
Regards

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

The tips I got with this Kensington 33197 power adapter have numbers stenciled on them like N3, N5, N19, etc. The tips sold on their web site make no mention of the "N" numbers and have numbers like K20059, K20050, etc. and there is no cross reference.

You can also see a complete reference for "N" numbers to all the laptops they support at the above link. Again, no mention of the numbers Kensington uses on their site.

I need a cross reference for these kinds of numbers.

Kensington referred me to their telephone tech support; but, there is a language or cultural barrier that prevents their understanding what I need.

Does anyone know of such a reference?

Hopefully someone here can help solve my issue, because I'm practically at my wit's end with it. I recently ran Lenovo's Updater program and it installed a few new things on my Laptop... I don't remember all of them, but I know one was a BIOS update, a Firmware update (can't remember specifically for what though), as well as a few programs I was missing on my computer (like Lenovo Power Management, just to name one).  It's something I hadn't ran for a good year, so I'm sure everything was using an older version! In any case, it seems after I did that, many of the games on my computer started playing worse.  Long story short, after checking out a few programs to monitor what my computer's doing (CPU-Z, and even Intel's Extreme Tuning Utility), I noticed that my Laptop's suddenly only using a portion of what it can do. For example, the core speed should be able to go up to 2.6ghz - 3.3ghz... but strangely, it's staying at a solid 1.20ghz the whole time. No matter if I run any graphic-intensive games or do anything else that might need some extra power, it stays exactly at that number. Here's the weird thing though.  If I unplug my Laptop and let it run off the battery?  It shoots straight up to the 2.6ghz-3.3ghz, as it's supposed to.  As soon as I plug it in again, it drops right back down to 1.20ghz and many of my games run like crap again. I've tried looking up solutions online, but I've found nothing that helps.

I recently bought a Dell inspiron 5559 (June 1, 2017). I then noticed that whenever I play audio like music or videos and plug the adapter out, I would hear a crackling sound, sounds as if its coming from the speakers. When I pause the sound and unplug then play audio the sound is made so I'm guessing the problem seems to exist whether I play audio or not. No matter where I plug the adapter out, it makes that sound. I'm worried that it might destroy the laptop, or that this is a defect that might start a fire if its a lack in how the adapter was made. It is a 45 w adapter according to what is labelled on it. sometimes i get a message saying "adapter is not recognized. system performance will be impacted etc" and I guess it happens if I don't plug the cord in properly? or is it not suppose to say that at all? Nonetheless, my main worry is the sound the laptop makes when I unplug the adapter. It goes on for maybe 3 or 4 seconds and sounds like a radio transceiver. Please comment if you know what this means, Thank you.

Since i bought a new laptop E7270, is it allowed to use my power adaptor my old Dell E6420 also for the new one?   If so i can use one adaptor at home and another in office and dont need to carry the power adaptor always.
Will this impact the battery performance of the new laptop?

A:If it is possible to use the power adapter of E6420 for my new laptop E7270? Will it impact the battery of the new laptop?

If the connector fits (it may not - the older systems use a much larger barrel connector than many of the new ones), AND the power (wattage) is equal or greater, yes.

Hi,First of all sorry for the bad english. It is not my native language. I upgraded my E550 to the new aniversery update from windows 10. And since a couple of days my computer freezes when I'm unplugging my chargerI have to press the power down button to restart it and to get it to work again. When I restart my Laptop the battery is not charging when I my charger is plugged in.Also when I do that it sometimes creates a BSOD with a message DPC_WATCHDOG_VIOLATION And when all this is over it works fine again. I tried searching for driver updates but I don't find a new version of the charger driverAnd I didn't came across other people with the same issue. I also don't see the point in upgrading the BIOS since my laptop (like most) starts in UEFI Kind regards Brecht

Hi. I have a Dell Latitude E7440. The laptop boots to the desktop fine while its connected to the AC adapter. It also boots fine while on battery to the desktop and operates normally. But the problem occurs when I connect the AC adapter while the laptop is powered on, it freezes, for example when its on the desktop and i connect the AC adapter, it freezes and doesn't respond. When I disconnect the AC adapter, it resumes and operates normal again. When I connect the AC adapter again it freezes and when I disconnect, it resumes to normal operation. The third time I connect the AC adapter, it does not freeze. What could be the problem? Any help appreciated please.

I own a 2 year-old HP Pavilion dv2500 running the 32-bit Vista Home Premium (service pack 1). It has an Intel Core 2 Duo CPU which runs @ 1.50 GHz, along with 2 gig's of RAM.

When I first got it, it ran fine. After a while, it began to freeze up when left unattended, but only when disconnected from the included a/c power source. I ran Verizon Internet Security Suite and Windows Defender spyware/virus scans, and both came up clean. The incidents have only gotten more frequent. Now it freezes even when not unattended.

When I say "freezes" I mean freezes. Not "all-programs-won't-respond" frozen, but "mouse-won't-even-move-and-I-have-to-hold-down-the-power-button-or-rip-out-the-battery-to-shut-it-off" frozen. The laptop always ran a little hot, and I figured that the battery was the problem, since a/c power completely bypasses the battery. I learned that my battery had been recalled. I have a new battery pack now, and at first it was better, but now the freeze-ups are again becoming more frequent.

There's a slight correlation between the amount of RAM I'm using and the likelihood that it'll freeze; if I'm just browsing the web, it is less wont to jam. I found via Google search that it might be the graphics card, but I have 385MB allocated to the graphics card, so that makes no sense.

I really would like to be able to use my laptop as a laptop, and your advice and comments could not come too soon, even if it... Read more

Welcome to TSG forums!
How long has it been since you ran disk cleanup?
You might try using the free program ccleaner. It is available at www.download.com,, www.filehippo.com or www.majorgeeks.com.
If you choose to use it, please disable the registry cleanup. Many of us here at TSG recommend NOT using any registry cleaner, because of the problems they can create.
Post back and let us know if this helps at all. We can give other suggestions if needed.
