Preferred Solution: No power to PC but I get a green light on motherboard

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.)

Answer: No power to PC but I get a green light on motherboard

The eMachines power supply (and possibly the motherboard) is bad. Just because you have a green light, doesn't mean that the power supply or motherboard is good. It takes many separate voltages to operate a computer. The geen LED means only that you have +5volts to the motherboard

I have a Sony VGC-RB42G computer. I recently moved my computer, cleaned off all the dust, and when I plugged everything back in, it won't power up. The light on the power supply blinks green, inside the motherboard also has a green light that blinks as well. It has a ticking sound too, but I am not sure if it is coming from the power supply or the motherboard. Any idea what could be wrong.

FYI, I have already unplugged everything from the power supply, pulled out the ram, checked the battery, and put everything back together and still no change. One thing I thought was strange was after I unplugged everything, I pulled the power into the power supply again and this time the green light came on but did not blink. It stayed solid.


Answer:No Power, Blinking green light on power supply and motherboard

Sounds like a Power Supply problem.

So today I was just watching a YouTube video, not gaming, not doing anything too intensive. Suddenly my computer shuts off with the power button blinking green. No BSOD, just powered off and won't turn back on. I tried unplugging the power cable and holding down the power button for 30 secs with no luck. My computer is pretty hot idle at 60 degrees Celsius. But it's been this way for years with no problem. Could something overheating just by watching a YouTube video? When a CPU overheats it goes into blue screen right? So it can't be my CPU. I have a cooler master PSU. CM is a trusted brand. And I also have an MSI motherboard.

Answer:Computer randomly turns off with green blinking green light on power

Doesn't necessarily mean the screen will blue out because of heat problems mate run the BIOS and post back the readings for the CPU temp (seems a tad high to me for idle) and the CPU fan speed.

The other thing to do is check out the PSU as well via these
PSU - Jump Start

but try the BIOS first and if you do the PSU stuff DO NOT attempt to open the device itself you just need to measure the volts on the leads. However volts does not necssarity mean enough current (amps)

I picked up this Alienware 5700 off ebay to hopefully refurbish for my son but I'm new at this and still learning and so this thing has me baffled. The laptop is in pristine condition but shows no signs of life. When I plug in the power supply the green light on the power supply goes from solid green to blinking rapidly to the point you can barely see it. To me that would mean a short somewhere right ? If so where ? Has anyone else ever had experience with something like this ? I just don't want to go buying a new battery for a laptop that maybe fried already. Any help would be greatly appreciated.

Answer:No power, no lights but green light on power supply blinks rapidly

Remove the laptops battery and try the AC power only. If the green light does the same, it still could only be a bad AC adapter, or at worst, a shorted laptop motherboard

My Problem:

Tonight I went to turn on my PC and the machine was "dead" so to speak. No fans/drives attempting to boot up or anything, even momentarily, just a completely dead machine. In addition to the machine being "dead", I noticed that there is a green light on the motherboard that remains on when the machine is plugged in with the PSU turned on. PSU fan is not turning on either.

Things that I have done to try to fix this:
-Change the power supply.
-Bypass power button switch.
-Reset bios by removing battery. Also tried different battery.
-Remove RAM, hard disk and CD drive. No beep.

Obviously, none if this has brought my PC back to life so I am wondering what could be causing this? The PC was not moved or anything recently and no hardware / software changes of any sort have been done recently.

However!....(I dont know if this is worth mentioning or not) it might be helpful to make the following known: When PSU is connected, there is green light on motherboard.

Also, when I lift 20 pin power connection to motherboard( littel bit not compeletely), PSU fan, processor fan runs and get orange light on cabinet. Also green light on motherboard turn blinking green light. But still computer is not booting up and nothing on monitor.

What do you think could be the cause of this? Any ideas?

Answer:Computer doesnt start. Green light on motherboard

I build the computer last night, spent lots of time making sure I followed all the directions. Spent about 20 mins wondering if I should turn it on to see if the processor fan would turn. After a few ciggys I finally build up the courage to turn it on and it all lit up wonderfully. Power light and case fans came alive CPU fan turned and the monitor flickered to life. Went through the BIOS and set the DVD Drive as the boot disk so I could install Windows XP.

Restarted my PC and it asked me if I wanted to boot from CD or HD went for the CD option and started the Window installation, it then said that it was a new HD and needed to be formatted I said ok and at 5% I realised that I was actually installing Windows ME by mistake. Being the stupid person I am I turned off the powersupply switch.

My PC wouldn't turn on on Monday night - just a green flashing light on the front. After a bid of fiddling with the kettle lead etc and moving the pc, it worked. After switching off as usual the same thing happened the next night. I replaced the kettle lead but now it just sits with the green light flashing. I've checked the forums but can't find someone with the same problem in that the pc DOES work every now and again. PC about 15 months old. Has anyone any suggestions (hoping its not the hard drive).

Answer:Solved: Green Flashing Light no Power!

Solved - had a chappie at work have a look and the fan doesn't move. By the way the green light now doesn't come on at all. It's the psu and it's being fixed later. Thanks for looking and hopefully this may help someone else!

I am working on a frends desktop that recently might have been hit by lightning. After a big storm their desktop would no longer power on. Now, I am no stranger to computers. I unplugged the motherboard main connector and I get a solid green light when I plug the psu in. Plug the main connector back in and plug the psu in I get blinking light again. So either its the PSU or mainboard. Im thinking psu since usually that is what goes first, but at the same time I am leaning towards mainboard. what do you all think? On another note, Are these boards proprietary? I have a few standard ATX PSUs I could test my theory with but not if I have to rewire them.

Hi folks, having a problem here. I have the motherboard in the title and just yesterday after shutting down and replacing a fan, my computer will no longer turn on through the case power button. I thought it might be the case wiring that is shot, but I tried booting the system by doing the "screwdriver to the power pins" trick. I dont even get a reaction at all. I have taken all the parts off and put them back together, but still the same. So... did my motherboard randomly fry from just replacing a fan.. (maybe dust?) I'm not sure. I just need some assurance on if it is the motherboard so I can get a new one. I dont have any other computers at the moment to check the parts. Thanks guys, and please try to be swift.

Hello, I'm trying to figure out if the power supply on my hp is bad or not. The green light on back of the tower is flashing and the computer won't turn on. I've tried all of the preliminary things and nothing works -- the green light keeps blinking until I disconnect the large plug to the motherboard, then the light stays on and doesn't blink. Once I have the power cord disconnected and the main plug to the motherboard disconnected as well, I then have tried replugging the power cord and then replugging the main plug to the motherboard (kind of trying to jump start it), the fan tries to come one (but only for a second, then goes back off, so it won't boot).Does anyone know if this means that the power supply is bad or if something else might be wrong? I'm wondering if the power supply would be bad when the computer is clearly trying to start, but not quite making it.

Answer:no power and green light on my hp pavilion is flashing

If the PSU blinks it needs to be reset.unplug the electrical cable from the wall and the PSU.move the red voltage selector to the opposite position it is in and then slide it back. If you live in the USA 120Vac-->220Vac-->120Vac see the image below.  After you have done this you can plug the power cable back into the PSU.  Connect the power cable to the wall power. If the PSU is still serviceable it will no longer be blinking. Best regards,erico Edited to fix the broken image link.

Hello everyone

This is my first post, as well as my first build attempt, so please be gentle.

P4 3.0 ghz
480w psu
1 stick MD4412UOE 512MB DDR-400 PC3200 Power Memory
Integrated Intel Extreme Graphics

I purchased all of my parts from newegg, and i finally found the proper time to put everything together. After getting a cpu fan that was too big, i purchased a AeroCool cpu fan. I had to remove the P4 retention module, and I now have the fan installed. I installed everything else (cd-rom, hdd, disk drive), and I turn the power on, to find that nothing is happening. I have taken the mobo out of the case to make sure it isnt grounded, and none of the fans power up. The only indication of power I get is the green stand-by light located between the second and third pci slots, and the keyboard lights flash on, then off. Whenever I turn the power switch on, the same thing happens with the keyboard and the rest of the mobo.
I have a buddy who is also putting together his own build, and he said that it was strange to hear that not even the psu fan is starting up. The psu has two power receptables, that I can best describe as female and male. Dont know if this makes any difference. I dont know what to do, and I was wondering if this sounds even remotely familiar to anyone. Am I missing something with some of the jumper settings, or does it sound like a huge problem?

My sister-in-law has an eMachine that she turned off and unplugged before leaving for vacation. A week later she returned and plugged it back in only to find it won't turn on. I don't know much about this pc other than it's a tower and about 3 or so years old. I figured it was probably the PSU (power supply) but wanted to verify as many things as possible. Basically, there is a green light on the back of the pc (on the PSU) that will flashes on and off when you try to turn on the computer. The PSU fan doesn't spin and nothing else makes any attempt to turn...just dead.

I pulled all the power connectors and jumpered the power switch pins (15-16), this gave me a solid green light on the PSU and the fan spun normally. I tested with a voltmeter and got the proper voltage on all the pins. I am thinking that this probably rules out the PSU but not 100% as something could be 'pulling it down'???

Any ideas on what else to look at? I hate to buy a PSU when it appears this one is ok. That pretty much leaves the MoBo and/or CPU. I've pulled all the cards and memory trying to get it to do anything and nothing affects it. I suspect there is something wrong with the MoBo but don't know how to verify that.

Any help or advice is appreciated. Thanks!

Answer:eMachine power supply (PSU) green light flashing, won't turn on

What you need is a PSU Tester which you can get on eBay that will tell you if the power supply is bad.

I am new to this excellent forum and wondered if anyone out there could possibly help......

I have a Dell Optiplex GX620 Desktop PC. Several weeks ago I had a slow flashing amber power light, indicating a PSU or switch fault. Firstly I replaced the switch - made no difference. Then I replaced the PSU - The slow flsahing amber light has now changed to a blinking (very fast) GREEN light on the power button.

All of my research so far has suggested that this suggests the PC is in standby mode! But the PC isn't even switched on - no fans running etc. In desperation I have even plugged a USB mouse in to see if I can "wake" it up! I have a amber AUX_PWR light on the Motherboard which is on.

Nothing happens when I press the power button - no matter for how long I press it in!

Has anyone got any ideas?

Hi I've had the Dell XPS 8700 for over a year now and it's an excellent Desktop.
I've recently moved my tower to a new location and notice there is a solid orange light on all the time inside the PC, I believe it's on the motherboard... should I be worried this is on all the time? It's just I've never noticed it before.
Also on the back of the PC there is a solid green light, I'm guessing this is to just tell me the PC has Power.
I tried a google search but everyone with the orange light seems to have PC issues, my pc is working fine as far as I can tell.

LED on the motherboard will be on as long as the PC is plugged into a working outlet. It's perfectly normal and nothing to worry about.
If you unplug the PC from the wall and press/hold the power button for ~15 sec, that LED will go off. Again, perfectly normal...
Green LED says there's power to the PSU.

Hello, I the power supply light of my Media Center m1050y is blinking and the PC does not turn on at all. So I tried the troubleshooting sequence posted here in the HP Support site, and after unplugging all the cables and replugging them one by one, it turns out that the light blinks only when the PS is connected to the mother board (the connection is a white, wide plug with about 12 pins - pardon my ignorance on the actual name). I looked on the internet about trying to narrow the cause on the motherboard and I unplugged the front USB ports, the fan, and other "solutions" without any luck. Does this mean the motherboard is fried and either I need to replace the motherboard or look for another PC? Thanks!

have a T7500 that when rebooted, will take anywhere between 10-15 shutdown/startups before getting boot screen. Power button is green and 3 4 stay green when it is attempting to boot. I can't find what error this might indicate... any help would be much appreciated...



Answer:T7500 green power button 3 4 green lights, takes several attempts before getting boot screen

ubearcat,The led error represents ACPI S3 Suspend to RAM Windows Standby State. Try the steps below to resolve.Changing the power management options in the operating systemSometimes just changing the software settings in the operating system power options will fix the issue. Access to the power options in Windows can be done through the Control Panel. Depending on your version and view by settings, you may or may not see a power option link. In that case, look for power options under the hardware category. Once there, create a new plan or modify an existing plan, changing the advanced settings as needed.If changing the operating systems power options does not fix the problem, you can try changing the APCI setting to the computers Basic Input/Output System (BIOS).  Once there, you need to look for Power Management Options. There you will find the different ACPI standby states.

Hi, I've just about had it. I am running a Dell Dimension 2400 with Windows XP SP3. I experienced no major issues until August of 2010. I first became aware of the little game my PC was playing after installing the Shockwave Flash 10 update. Initially, the problem presented as a white screen when attempting to watch Hulu in full screen. A short time after, I began experiencing audio drops while both streaming music via Pandora or while engaged in conversation via the VOIP (non video) side of Skype. I don't recall how, but the full screen/white screen issue disappeared. The problems remaining however have proved more frustrating.

Present day, I still experience the audio problems. For example while talking on Skype to either a landline or cell phone user, I will often (but not always) hear a little pop and the audio will go out. The lone remedy I have found is to close the skype window and fully 'Quit' the program. Upon which, I will promptly hear another pop, signifying that audio functionality has resumed.

While streaming video, whether from Hulu, Netflix (especially) or an embedded YouTube on Facebook, video will play for a few moments or minutes and then will cease, freezing the frame currently showing. For the sites utilizing Flash, the remedy has been 'Disabling' then re-enabling the Shockwave Flash Add-On in Firefox. In effort to determine whether this was a Firefox issue, I installed Google Chrome and then Internet Explorer this w... Read more

When I turn on my CPU both the red and green light come on. I have it pluged into a power strip and if you turn the power strip on and off real quick the CPU will come on. If not, the only thing that will come on is the red and green light and it will not boot up.


Answer:Red and Green Light on CPU

Just to check... you mean the cpu as in your computer... not the central processing unit... right? Try using a differnt power strip or non at all and see if that works. Which lights do your red and green leds correspond to? If you are booting both should light up. The green is usually the power led (is always lite green when on... yellow when on standby) the red is usually the HD or IDE led... lights red when the HD or an IDE device is being read/written to.

Question: Green light off

I am not sure which subject this comes under but here goes.  I got a Del inspiron 7720 that came loaded with windows 8.  I replaced the hard drive last year with a solid state and installed windows and then before the free upgrade to windows 10 stopped I put windows 10 on it.  
    The green led light was working for months to tell me to hit the FN+F3 key to turn off the touch pad.
Yesterday I noticed that no longer works. 
Nothing I tried has got the green light back on so I can use this function . 
  No errors in device manager. 
I ran the hardware thing when booting by hitting the f12 key but it said no problems found.
  Any idea on why this green led light went off ? and I am no longer able to turn the touch pad off and on.  I would like to just disable it as I never use it but I see no way in system BIOS to do that.  Any tip appreciated.  Tom

Answer:Green light off

I'd suggest you power off system, and then disconnect all peripherals - printer, flash drive, external drive, etc...). Remove AC adapter, battery, and then press "Power On' button for 15 seconds to release Status Flea Power. Replace battery, adapter, and power on system. Hopefully touch pad's enable/disable button is fix now.

Hello,I did a system build. Asus MB M4A78T-E with AMD Phenom II 965 Black Edition and Cooler Master GX 750 PSU. I followed the connections very carefully. When I boot up, all I get is the green SB light on the motherboard and absolutely nothing else! I am a bit frustrated right now! Any help would be greatly appreciated please. Thanks P.S. Nothing smells burnt whatsoever...whew! But I can't figure out what's wrong???

Answer:Help Please! Only green SB light comes on?

Greetings, Thlorian.

Relax, and start over. Check every step as you go.
Make sure that the motherboard is not grounding to the case.
Connect only the power supply 24-pin connector to the motherboard, see if you get any indications at all.
Make certain that the RAM is installed correctly.
Then, add your discrete components one by one, verifying each step.
If you're using a graphics card, try using onboard video as a troubleshooting procedure.

I have a Belkin 4 point hub which is powered from the mains. into the hub is my speedtouch adsl modem, canonlide scanner and a belkin wireless mouse. into the usb sockets at back of computer I have an epson r200 printer and the usb hub. I have tried various permutations of wiring to no avail.

When this is done the green lights come on. Using winxp. this is now getting annoying. when I have to reboot for whatever reason, this problem does not arise.can anyone help???

Answer:no green light indicators on usb hub

sounds very similar to my post earlier with a similar prob and it was suggested that i try what you have to do (unfortunately prob has not reappeared so cant verify) but apparently if it works it is an indicator that the power supply itself is on the way out.johnny.

I have an Optiplex 760.  I was looking at the back of the case for a power on/off switch.  Although I didn't find one, I did see a very small push button.
When I push this button a green light comes on, and goes off again when I release the button.  This is with the machine turned off.  I haven't tried pushing it with machine turned on in case I break something!
Can someone tell me what this button is for, please?

Answer:Green Light on Optiplex 760

BIST.   Built in SELF TEST.
Green LED on the back indicates power is available not that the power supply is Ok.

Answer:"green" light flashing

One of two things come to mind. Since I don't know exactly what light what you're referring to. It's either A: The read/write activity of your hard drive. Or B: to a lesser possibility the data transfer activity of your network card.I would say you have about a 75% chance it's your hard drive activity light.

I have green lights on my modem except for the internet light at all. We have called Verizon and they said it could be the phone line. We do have phone service. Tried connecting to internet many times, have shut off the computer and modem, have checked the connections...we are puzzled on what else we can do or check. Suggestions would be appreciated.

Answer:Green light on Modem

Welcome to TSG:
Can I assume that this is a DSL connection through Verizon?
Have you tried unplugging the modem ,let it set for 30 secs,plug it back in?
You did not provide the operating system info,but check device manager,network adatpter,ethernet nic, to make sure that there are no error indications(? !,etc)
What are you using to post here?
Did Verizon or your local phone co run a line check?
If the line tests are ok,my suspicion would be a faulty modem,or a faulty line filter,if DSL.
If DSL,have you tried connecting another phone cable to the modem and another ethernet cable between the modem and pc?
If your ISP supplied the modem,is it still under warranty?

have brand new battery, so figured prob was solved, but when hooked up, the AC adaptor has green light but laptop won't turn on, what could prob be??

Answer:Can Ac Adaptor be bad even if the green light is on?

It's generally a good indication if the light is on then the adapter is ok but you can only be certain by checking it with a meter.The more common issue is with the circuitry inside the laptop - the connector coming away from the motherboard is a very common fault, but once you've checked the adapter then it's a matter of stripping down the laptop.

Answer:green light next to camera is always ON.

I seem to have the problem fixed; or at least worked-around... I disabled a service at startup (from msconfig) called CameraApplicationLaunch..... after I turned that off the light went off. The camera wizard and the roxio software still seem to be fine. Doesn't make alot of sense, but I don't have the "green-eye" looking at me after boot-up now!

My laptop was working fine yesterday, charging and powering on an off normally. It updated without my telling it to. When it was complete (since it said don't turn computer off until finished) I either just shut the lid or I shut it down when it was done. This morning when I wake up and try to turn it on it won't power up. Then I noticed that the power button was blinking, like it is in sleep mode, tried pressing 10 times then holding down power button for 30-60 seconds and still nothing. Next I saw that although the power is plugged in the battery light won't come on. I don't know if it is charging (it could be dead). I tried a bunch of different outlets and that isn't the issue. I also listened to the computer and there is a very soft high pichted noise that dissapears if you unplug it, and that when you hit the power button and it starts blinking, the sounds changes fom high to lower pitch and back again over and over. But no other sounds or fans kicking on or drive spinning. I am pretty sure it isn't the power cord but have no way of checking. And I can't remove the battery without voiding the warrenty. Anyone have any advice, besides calling to have Lenovo send me a box to send it back to Lenovo since it is only 4 months old and still under warrenty?

Answer:Lenovo Edge 15 laptop 80K9 battery light won't come on, power light blinks

Suggest you eliminate problem 1. Do you have spare power supply unit? Worth trying that first. Your battery may be in sleep mode and won't wake up as battery is drained and hence needs charging. 2. You can go to local retailer and suspect a good one (John Lewis) will let you charge it for 30 mins. Ideally go back to person you bought it from. 3. Once you are in use restore to go back to last working point. I have to telll you the support from Lenovo and Microsoft was very very very disappointing. I tried to even return the PC and swop for HP as mine is only 2 months old. However, the answer was send back to Lenovo. Hope you find a way to get it charged

I will turn it on and after a minute or two the monitor goes to power save mode and the hard disk light goes from off/blinking to solid on and the power light stays on.

I have reinstalled the operating system and i thought that fixed it. I had SP 1 i installed all of my updates and SP2 and it starting to do it again (it will do it in SP1 but not nearly as often or when i run a flash heavy program: PSP Video or even the Scion website).

It will not do it at all in BIOS as i did every test on the diagnostics page for my hard drive (all pass) though if it turns off it usually turns on and runs dskchk and it wont stay on for that

In safe mode it is also fine it will not turn off once

I dont know what i did last as it was fine then i was gone for a month and I had it unplugged etc., came back hooked it up and it started doing it after a little while

I have taken a can of air to every inch, switched the Flat cord going to the HDD from the Motherboard.

All fans run fine

Thats all i can think of right now ask me anything else you need to know

I'll give this forum a couple of days/a week maybe then i'll take it to a local shop to diagnose it

Hi. Tonight I had a problem with my laptop. It was in sleeping mode, and when I open the lid there were no mouse function and no touch screen function. So the only thing I could do was to press the power button for 3 seconds to turn it off, but it didn't completely, because the screen turn off, but the power button light is blinking just like when it is on sleep mode, and I'm not sure if the hard drive light was on, off or blinking before this, but now is blinking. I press the power button and nothing happen, I press it for 3 seconds and nothing happen. I even did the HDMI connection to another monitor, but both monitors don't show anything, not even recognize that something is connected to the HDMI port in the new monitor. There is no sound, nothing, just the 2 blinking lights. What should I do? Thanks PS: I'm not sure if it's Windows 10 32-bit or 64-bit. It was upgraded from Windows 8

Was experiencing general issues with my windows profile after windows updates last patch Tuesday so I initiated a system restore and let it run today.  After completion laptop turned off (instead of rebooting?)

Pressing the power button: Power button turns white (on) for ~30 seconds, then laptop turns off (indicated by power button light)
no fans
no screen (back-light or otherwise)
no POST codes - beep codes or light codes.  
no other visible activity

During that period nothing else happens, unless I press the power button again. If I do this
The fans spin up momentarily
The system then powers off (as indicated by the white power light)

I've tried:

Disconnect power/battery and hold power button (60 seconds)
Power system on with just battery
Power system on with just wall power
Remove mSATA HD and repeat the above
Disconnect video connector and repeat above
Remove mPCI WiFi module and repeat above
Completely disassemble and remove CMOS battery (tested at 3.1 VDC) for 60 seconds, reassemble and repeat above

All with no change in behavior

I am able to get a light code 2 Amber / 3 White if I remove the RAM module (as expected)

Yeah, mine does this as well. Another QC failure.It's probably possible to resolve by taking apart the screen bezel and putting something in between the camera and the LED, or taping over the LED entirely, but it is a somewhat useful indicator.

okay, recently my sister's floppy started to not work at all. My dad eventually tried to work on it and couldn't figure it out. Heres the facts:

my dad swapped my floppy into my sis' computer and it still didn't work. I know power is getting to it cus there is a plate at the bottom that spins when plugged in.

My PC has been down for repairs and when i got mine back up and running i realized that my floppy doesn't work also. It worked before he put mine into my sis' computer.

When i boot up the bios recognizes it and so does windows but it wont read anything. When i try to use a boot disk it wont read...when i try to get windows to read wont.

Could my sis' computer have a possible problem with FRYING floppy DRIVES?

I do have one more trick up my sleeve. What I'm going to try is to put my friend's floppy in mine just to see if its my mobo, bus cabling or the drive itself.

I suppose it's a 2.0 usb device since a 3.0 one would be unsupported in VBox for now. Well 3.0 is backwards compatible so maybe I'm wron on this one.
It means that VirtualBox detects it but it should only turn on if you have added a filter to it in VBox:

If your usb list is empty like this screenshot then I'm afraid that your camera and VBox don't go along pretty well:

What I mean is that VirtualBox doesn't support 100% of the USB devices on the market.
I also have a cheap 2GB usb stick that always blinks but remains undetected for host and guest as long as VBox is on.
Some other lexmark printer was only half supported in VBox: scanning worked, printing not (or printing worked and scanning not ,depending of the driver version)

1.0 usb is by default supported.
For usb 2.0 (like in the screenshot) you'll need the VirtualBox Extension Pack:
For this one in the link, you need the latest VirtualBox 4.1.16.

Using an older Virtualbox like 4.0.6 - 4.0.something else in this range has some regression bugs that gives errors to all usb devices (avoid this).

If nothing helps just unplug the cam or disable usb support (uncheck the checkboxes you see in the ... Read more

I shutdown my computer last night and I saw a green light from the back of my hp computer. It wasn't blinking or making any noise so I decided to ignore it and go to sleep. This morning I woke up and the light was gone. What was it? Ithere was no power outage last night or bad weather. I turned off y computer like every normal day and I saw the green light just on, and now it's gone. Should I be worried

Answer:Green light on at the back of my hp computer

Could be a light to indicate the power supply has power, which some HP's have, or a Ethernet connectivity light, or a wireless activity light, or something else. Or it could be from the inside of the computer and be a light from the motherboard that indicates power. Hard to say without more details or best yet a picture of the back of the computer with the location of the light. If the computer is working I doubt there's any reason to worry, green lights tend to be indicate good or proper operation anyways.

My printer fell off my table. The green light is flashing in the back when I plug up the power cord but it will not power on. Does that mean that the printer is damaged or is there something I can do to get the power to work.

I'm helping a friend fix their computer monitor and I'm a little stumped!

They've got a Samsung SyncMaster 930B monitor with constantly blinking green light and no images displaying, just a black screen. Pushing the power button on the monitor does nothing, not even turn it off. Unplugging and replugging it also does nothing to the blinking light. The screen will not turn on, not even during reboot. The hard drive fan seems to be running and computer seems to be processing during reboot. I even tried hooking the monitor up to a laptop to see if it would work, with no results.

The computer itself is a three year old HP Pavillion a1340n with Windows XP Media Center Edition 2005. It has Norton Antivirus. Unfortunately, I cannot get in to see if there is anything else wrong with it without lugging another monitor over from somewhere else and trying to hook it up.

Answer:Help! Blinking Green Light on Monitor

If, as you indicate, you've tried it on a known working system and it still doesn't work then the most likely culprit is the monitor itself. If you can find a reasonably priced repairer then get them to fix it. It usually works out a lot cheaper, tho', to buy a new one.

i have this problem it just start like yesterday and when i turn on my computer it sounds like its booting up like normal except the monitor will just blink with a green light and i checked to make sure the cords and everything was good and it still dont work.

Answer:green flashing light on monitor

A light blinking at a rate of at least once every second often seems to be made to indicate there is a problem, as in the makers of the device that has the light did it to show that there is a problem, so at least the monitor "knows" there is a problem...So maybe you should read the manual or contact the manufacturer and see what the blinking light means.
First things I would try are to plug it into a different PC, trying a different data cable, a different power cord, and a different outlet. If all of the above fails (including reading the manual or contacting the mfr.), it is probably a part inside the monitor not working correctly. Make sure all connections are secure, and not crooked or anything, including the video card's (if there is one) connection the the motherboard's slot, any internal power cord to the video card, etc.

i have a dell desktop.. i restarted my computer the other day and when it would not restart..only stay on the logging off logo..i maually shut it off. now when i try to start it.. it makes a real loud humming noise like a fan..and all i get is a yellow light on the power button and it does not start.. i checked the fan that is in the front.. over the cpu i think.. it is turning but was covered with dust on the solid screen in front of it.. any suggestions? it is a dell xps 420.  the sound sounds like it is coming from the fwd fan or near it.. thanks!!!

Answer:loud noise and no green light

You need to do some serious housekeeping inside that case...A can of compressed air is good for this...along with a soft small paint brush for the stubborn dust bunnies...Also when blasting the fan areas use a Q_Tio to hold the fan blades in place so they don't get damaged...As always remember to remove all power sources and take anti-static precautions...PS: After completing this there may be a fan replacement involved...As long as you take it with you you should be able to find a suitable replacement at any PC shop...

Hello: My T61(type 8891) won't start. I'm getting a series of flashes from the battery and power lights: A/C power connected: power light flashes green alternately and battery light flashes green then red/green.AC off, battery installed: power light flashes green at the same time as the battery light flashes red/green. This happened twice before in the past 2 weeks. After about an hour, it booted up - no problem. This time, nothing. Thanks in advance for any assistance.

Answer:T61 Battery light flashes red and green

Answer:Green light on at the back of my hp computer

Most HP power supplies have a green LED light lit on them, but its always lit when power is present. Can you better describe the location on the back of the computer that this light was coming from?[ Generally with most computers and other electronic devices GREEN = GOOD & *RED = BAD ]*RED can also be a normal color indicator for hard drive activity, back lighting to keyboard on laptops etc, and some gaming motherboards glow red with multiple LEDs, charge indicator showing that its charging and not at full charge to be green etc, and so on.

I also tried a different video card and still light keeps blinking and nothing appears on the screen. I suspect it is ethier the cpu or the motherboard but I have no way of know unless i go to compusa/bestbuy ect, and pay them $100.
The computer was custom built by me last year and just stopped working. There were no recent hardware or software changes. Please help ive been trying to figure it out for over 2 months and almost forgot all the fans and lights and hard drive and drives are running.

Intel 3.4ghz
Samsung 793MB(17 inch)
Ati 700X graphics
D925XCV (motherboard)
Lite on Cd/Dvd write/rewrite
Enermax 470 watts power supply
2 gb of ram
80gb western digital hard drive(caviar edition)
and that all thats important

Answer:Green Light On Monitor Keeps Blinking

if you are getting no output onto monitors there are only two troubleshooting sources left:

1. you have a bad/loose cable

2. your video card is messed up.

Since you have isolated the monitor as not being a problem, the error is either in your cable or video card.

swap out with another video card to see if that is the problem
