Computer won't boot without unplugging and plugging motherboard power

Q: Computer won't boot without unplugging and plugging motherboard power

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 appreciated.

The system is a abit kt7 mb with a WD caviar hard drive. I'm thinking the hard drive is the culprit since it has produced the same issues on 2 boards. I just don't understand why it boots only if I unplug and plug the mb main 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.

Hello I just purchased my lenovo x280 and have noticed whenever I plug or unplug the power the display flickers and goes black for less than a second then resumes like normal, this happens every time I plug or unplug the device. I saw similar posts about this being because it changes the refresh rate on a different laptop but I haven't been able to find the setting to turn it off

A:Screen flicker on x280 when plugging and unplugging from power

Hello and welcome,
 
Right click on the desktop background.  Select Intel Graphics Settings.  Select Power.  Disable Display Refresh Rate Switching.
 
I didn't know where to find it either until just now.  Thanks for getting me looking.  I'm going to leave it as is on my X280 to maintain whatever battery run-time the 48Hz setting saves.

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

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

When I plug a power cord in, the power light instantly (almost) lights up, whether or not I've pressed anything to try powering it up. When I DO press the power button, nothing changes. Nothing sounds like it's running at all. Someone suggested moving the RAM around, so I placed it in a different slot, but that didn't change anything. This was a frankensteined computer that was given to me, so I can't even really provide much in the way of specs. It's an IBM ThinkCentre S50 (shell anyway), but appears to be loaded with a 40GB Seagate HDD, Intel P4, 512MB RAM, and an AcBel power supply. In case this matters, and I don't know enough to know or what I would do about it, but there are a few open plugs for power. The motherboard has a couple plugs running into it, but one still open. The HDD has two empty plugs, but one plugged into it. I would have no idea how to play around with the power supply. Not to say that's the problem. Thanks for any help.
 

A:Computer shows power light upon plugging in, but no boot, noise, or any startup

It could be the power supply (officially called a "PSU" or Power Supply Unit) that's faulty and needs repalcing, but you were right not to go messing with it as even a faulty one can give you a nasty shock from the power that's stored up inside it. I've worked on fixing & upgrading computers for many years, yet even I draw the line at changing a PSU. I let my local PC shop do it for safety reasons, plus I believe in supporting little independant PC shops whenever possible.

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

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 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!

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

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?

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 I spilled pop on my lap top. nothing worked stay on for 20 sec then turn off. Took it apart cleaned it off with denatured alcohol and distilled water. let it dry for a few days. Now it only works in saafe mode. But it works more than before. I have no battery in. Only using power cord at first. I turned it on and a choice of regular start or safe mode or safe mode with networking, If I pick regular then it only booths as far as it plays a little tune the microsoft shows on bottom of screen. that is how far it gets. I turn it off if I turn it back on same thing happens. But if I unplug power cord from computer and plug it back in turn on computer then the safe mode screen choice come up. If I pick safe mode then OS vista come up on the screen. If I put the battery in nothing comes up not even a choice of safe mode.I did a restore didn't seem to change anything. I have read a few things like the bad ram I changed ram same, I read a bad cpu and heat sink. I took off heat sink and put on new thermo paste. now out of ideas. ny other ideas out there. I is a aspire 5610Z laptop.
Thanks

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

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

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)

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!!!

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 got a new case for a friends computer today, and set about removing motherboard/hardware from old case to install in new machine. While unplugging the ribbon cable connected to the 3.5 inch floppy drive from the motherboard, I ran into dificulties getting it to disconnect. I must have tugged a little too hard because the plastic surrounding the pins on the motherboard broke off on one side, though the pins did not seem to be ruined. I thought, "Well that sucked, hope it turns out ok." I did notice that 1 pin was not present on the motherboard like 3 pins in, but hoped maybe that was standard. Now after installing everything into the new case, and booting up the 3.5 inch drive is not being recognized. I don't know for certain if the drive was being recognized before. It is not recognized in cmos. Probably stupid question, but is it certain that I broke the connection on the motherboard?

I have a AMD 1600+ cpu and motherboard; the power turns on and just quits; I have replaced the power supply; still no go! I took out the CPU and the the power supply stays on when you turn it on; therefore, I thought I had a bad CPU; I replaced the CPU and and still no go!

Hi everyone,
I've just had an issue with my PC where i left it a while as i got engrossed in the TV, came back and monitor was in standby mode as you would expect, i moved the mouse around and nothing, it had all frozen. It's done this before and after resetting it's been fine, this time however it was failing to initialise any peripherals and the monitor. The fans were not kicking in properly and the red light was flashing in a particular rhythm. I know the mouse and keyboard werent initiliased as they both light up when on and the lights hadn't come on.
 
I tried switching it off completely, switched back on and same again, so i tried unplugging at the wall and unplugged the keyboard and mouse for good measure, still the same. I left it about half hour switched off at the wall and switched it back on. This time it ran and gave me a POST error stating that boot had failed and to check my settings in the BIOS. I did so, everything looked fine, so i continued. When prompted i selected start windows normally, and it booted fine, just perhaps a little slower than normal.
 
Once i was on my desktop i went straight to event viewer and the following events are logged right before the initial crash:

So tonight I shut down my computer and unplugged the VGA cable from my graphics card and tried to plug it into the VGA input on my motherboard. The reason for this was because I tried switched from dedicated graphics to integrated graphics (Long story). When it was plugged into the motherboard I tried switching my computer on and my monitor came up with 'no signal' and the light stayed orange. So I tried to plug The VGA cable back into my graphics card then I still got no signal!

II've tried everything from re-seating the graphics card and RAM to trying different monitors and cables. It simply isn't working and all I did was unplug the VGA cable from my graphics card into my motherboard VGA input. I can't post any detailed system info as I am writing this on my iPod (very time consuming!) as I can't even do anything on my computer. But my monitor was displaying everything perfectly fine before I unplugged my VGA cable (when my computer was shut down) I don't see what's causing this.

Any help will be greatly appreciated.

I have been have strange issues with my PC that lead me to believe there is a bad hardware component, and I need help figuring out which one exactly. I can't remember which one started first, but these two issues seem to signal the beginning of the end and started quite some time ago. First, the computer was unable boot from the hard disk. It would try and load and load and never get anywhere. It displayed some text about AEM new component detected or something like that. I had the text written down, but the paper is gone (it was about a year ago that this started). Sometimes it sounded like it was reading the CD-ROM drive. I would do random things like just restart it, restart and immediately open the CD-ROM tray, and eventually it would boot. Then it eventually stopped booting at all, so I put in the Operating System disc and just booted from that. The second problem that I recall that began around the same time was that the fan would "bark" whenever I clicked on My Computer or something similar caus... Read more
