Dell Optiplex GX620 Blinking Green Power light & won't start!

Question: Dell Optiplex GX620 Blinking Green Power light & won't start!


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?

Many Thanks in advance

Hello guys i hope someone can help me. My desktop stoped working and it showed me the amber power light.
First i cleaned the inside of the desktop from dust. I checked the battery it was fine ( 3V as indicated) then i checked rams. Also fine. Checked the video card also fine. Then i figured maybe it's the power supply. I jumped it and it worked the fan works and most of the outputs are fine. Then i tried to plug only the 24pin conector on the the mobo , it worked fine the fan kept spinning the HDD worked the cd-rom workd ..there was no stopping. But once i pluged the 4 pin atx mobo ps, every thing stoped again. I repeated the same thing 3 times. Once the 4 pin atx is pluged everything stops. What should i do. Is it the mobo ? Please help

Answer:Amber power light of death flashing Dell optiplex gx620

Hi Eddysam,
Please check the power button if it is solid or flashing, is there any pattern for the same. Please check the keyboard caps lock and number lock key if it toggles while the system is turned on.

My refurbished dell optiplex GX280 worked fine until a month or so ago when I moved it to another room in my home. When I powered up, the power light was blinking amber. I tried all of the options that did not require buying new parts du to financial reasons, so it's sat since then.

I just decided to look at it again and powered it on. Everything seemed to start OK but no dispay. The diagnostic lights indicated faulty memory. I then located and removed the faulty DIMMM, and it started right up.

About ten minutes later the computer shut off by itself back to the blinking amber power light. :evil:

Any info would be appreciated Thank you. :grinthumb

I have a Dell Optiplex GX620 minitower that was working just fine until a couple of weeks ago, no problems at all. One day, however, it wouldn't power up; instead of the green power light, I got a blinking amber light. I tried unplugging everything from it and letting it sit for a bit, but it still won't power up, and it still gives me the blinking amber light.

I have checked the chassis intrusion switch, and I have replaced the motherboard. I've also verified that the power supply is functional. We did try unplugging the memory and video cards, and it still won't work. We also checked that all of the USB ports seem to be fine. We also tried a different power cord. None of the diagnostic lights come on at all.

Any more ideas?

Answer:Dell Optiplex GX620 won't power up

A blinking amber light on a Dell is almost always fixed by replacing the power supply. You said you verified yours was working but didn't say if you tried another. I would try another power supply.

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)

Hello, I recently purchased a Dell Optiplex GX620 Desktop pc in hopes of doing some upgrades on it. I am in need of a 400w Power Supply for this desktop, and I need some info on which ones are compatible.

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.

Hello everyone this is my first post here. I own a dell optiplex 745 with a core2duo 1.8 Ghz processor, 2 gb RAM and have also added an XFX HD 5550 to it. I have been using it since almost two years, and it hasn't caused me many problems except this blinking orange power light.
The problem is just this that the desktop just won't start. All that happens is that the power light just blinks orange. This has happened to it almost four times in the last two years, and the problem has seemingly resolved itself the last four times. Well it would go something like this: I would turn off the PC normally, and the next time i started it all i would get is this blinking light. Then after a couple of days or hours, I would try again and it work as if nothing had happened. But this time it happened four days ago. I turned it off, then switched it on but i got the orange light. Since then, I have tried so many times but this time I fear something much bigger has happened.
Now I have done a decent amount of work in trying to figure out whats the problem. The key thing to note is that its not my PSU (yes i used a different one). Does this mean it's my motherboard which is causing the problem? Or is it something else?
I did a bit of digging up on the internet for the same problem, and I saw one which said something about a faulty power on button

Answer:Optiplex 745 Blinking Orange Power Light

According to the Dell manual this is either a power supply or motherboard problem.  It doesn't detail how to further troubleshoot.
Do you get any diagnostic lights? or beeps when you power it on.
But, you can remove the video card to see if the symptom changes.  If not, reseat the memory as a next step.
If neither of these help you are back to either the replacement power supply or a motherboard problem.

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.

I have a Dell Optiplex 780 and when I went to power it up the other night it did not power up.  I'm getting a solid amber light for the power button and lights 2,3, and 4 are blinking above it.  Any idea what this means?

Answer:Dell OptiPlex - Solid amber light, lights 2,3,4 blinking

According to the 780 Service Manual page 13,
Solid Amber Power Light = Second state of the light at power up. Indicates the POWER_GOOD signal is active and it is probable that the power supply is fine. Look at the diagnostic lights for further information.
Page 15 shows that 2/3/4 = A possible USB failure has occurred. Disconnect and reconnect every USB device, then try to power on.

My Dell Optiplex 740 power button is blinking green an won't boot up

Relevance 93.48%

I have a Dell Dimension E510 that as of yesterday, won't power up anymore. The power light blinks orange and the computer does nothing when the power button is pushed or held in. It's about 16 months old and is out of warranty, so I'm trying to diagnose the problem myself.

I did some searching on the internet and found that this seems to be a common issue on these Dells, sort of a long term infant mortality issue. The most common causes seem to be a bad PSU, MOBO or a shorted USB input.

I've done some diagnostic checks/testing so far and am now stuck. Here's what I know.

- The USB ports don't appear to be shorted. I also disconnected the connector for the USB (which includes the power switch :banghead and it doesn't change any of the results that follow.
- I removed the power supply and jumped Power On (terminal 14, green wire) of the main ATX connector to ground. The fan comes on and all voltages (3.3, 5 and 12v)check out, including around 5.35v at Power Good (terminal 8, gray wire).
- With the power supply back in and everything connected, there is only 3.3mv at Power Good. As I understand it, this would normaly point to a bad power supply; however, all of the voltages check out when the unit is disconnected from everything.

Is is still possible that the power supply is bad, or is it more likely (or definitely) that the MOBO is the culprit.

Any help, including suggestions for additional testing is greatly appreciated.

Yesterday, I was just sitting there watching TV at my computer desk, with the computer on, next thing I know- I look over and the computer was shutdown. I didn't know why, so then I go to turn it on, it will not turn on- and the power button, that should be green, starts blinking orange. I'm not sure what the problem is, I think something might be dead. I have been getting a message that says "Alert! System Battery Voltage Low" for about 2 years, I'm not sure if that would be it or not (Maybe that died? Would that do it? I don't know).

When I try to turn it on, I can see the fan and stuff turn on for about half a second, then everything just turns off except for the mobo light and the orange blinking light. I've tested my brothers working power supply in mine, so I know that mine still works because that didn't fix it. I've taken the graphics card out, that didn't do it either. I don't know what else I could do, please help somebody, I'm lost without my computer... Thank you.

I have a dell optiplex gx620, and dell claims that with the cord It came with I can hook up 2 monitors, and have a multiple monitor split.

You have one VGA port, unless you have a video card in there. One source only. IIRC, there were y-cables, but I think those were for mirroring the monitors.

I I have an old gx620 ultra small form factor that I'd like to upgrade because it fits perfectly where it is and I haven't found any more modern unit that does. It has a pentium d820-2.8 ghz,800 mhz and I would like to go to a core 2 duo (e5200-e5800) if possible. I know it would fit physically but would this mobo support it? I have a gateway that can run both chips but I don't have a clue about the dell. I know it should run cooler, and that should quiet it down- the fan runs hard and loud when it has to start working. If no on the e series then how high can I go on the pentium d series chips? I know the d945 would be a good bit quicker, but again, will this mobo support it? Thanx for any info you may have.

Answer:Dell optiplex gx620 cpu

I don't believe the Core 2 Duo chips are officially supported, though if you updated the BIOS to the latest it may work with the older Core 2 Duos such as the E6300 and E6600 Conroe CPUs.  The chipset should support them but Dell sometimes locks down CPU support in the BIOS.The Pentium D chips aren't worth the money to upgrade to, they're all very slow compared to CPUs released in the last 6 years or so unfortunately, so I wouldn't recommend spending money to upgrade to the 945.

The device will start up but never boots to the dell logo or the Windows OS. This is with the AC plugged in and also with the internal battery plugged in.  After a few months, I had the same issue with the laptop yesterday.  Is there another issues other than the motherboard or could it be that the "refurbished motherboard" came from another defective Dell XPS 13 9350?

I am having a hard time finding the specs on this model. It is the smallest Optiplex GX620 that they make. I need to know specs on memory, what is the limit on processor upgrade, etc.

This was the closest post I could find for this request.. This computer has no slots at all for adding any card. It has built into the motherboard audio, 25 pin printer port, 9 pin port, ethernet, 5 usb on back and 2 on front with head phone and microphone jacks, only a dvi port for monitor NO VGA without use of adapter, and the power supply uses a model DA-2.

Please help with any info or where to find info. I keep getting info on the larger case models. I need to know memory type and speed to install and what is the highest performance processor I can use. The hard drive has been removed but from the cables it takes a sata hard drive. Really small case with not much room. Only 2 RAM memory slots.

I hate these small cases but I got stuck with several and I need to get them running to get my investment back. Please help!!

Answer:Dell Optiplex GX620 tag# 43dnv91

Here is the Spec Sheet From Dell. It is for all GX620 series but aside from expansion slots or lack thereof and case the basic motherboards / chipsets are all the same, it also has notations for SFF specific Specs. The Chipset is an intel 945G which theoretically can take up to a 800 or 1066mhz FSB conroe / allendale core 2 duo although those are not listed on the Dell supported list and Dell's are notorious for not doing well with unsupported upgrades not to mention that the SFF case could be a limiting factor. The Ram is DDR2 2 DIMM slots with 4GB max (2GB per slot).

Hello I wanted to ask about a graphics card upgrade for my dell optiplex gx620.

Current specs:

CPU: Intel Pentium 4 HT 3.00Ghz
GPU: Nvidia GeForce 8400 GS
HDD: Seagate 250 GB

I am pretty sure I can upgrade the GPU but don't know which card works the best for it. Also my Power supply is 280 watts.

Thanks and if you need more info please tell me.

Answer:Dell Optiplex GX620 GPU Upgrade

With the very small power supply you will be limited. Unless there is a pressing need for better graphics I would just stay with what you have. Many (most) of the Dell's in the period when the GX620 (2005 area) was made have proprietary power supplies. If you have the full desktop you "may" be able to find a higher power replacement. If this GX620 is the smaller compact case models I would forget it.

Dell only supports XP as the latest OS, although that is not the restricting hardware issue.

Sorry to be so negative, but you are very limited.

If you have a way to upload the minidump files (The files listed in the reports that you posted that end with .dmp) then I can run them through the debugger and see if it has any useful information. Since memory is typically the culprit, I would recommend testing your memory using Memtest86+. Let me know if you need help with this.

Hey there. I'm modding an old Dell Optiplex GX620.. Several actually. I'm turning them into bar top arcade machines that will run video game emulators. Well I was able to pick up 3 of these machines off craigslist for very cheap.

Once I get them all functioning properly and operating as intended, I'll be removing them from their Dell cases and installing them into an arcade cabinet. All the parts will be exposed inside the cabinet.

The problem I'm running into is the CPU's have these gigantic heat sinks sitting on top of them and a side-facing fan sucking the hot air from the heat sink fins and blowing it out the front of the PC case.

This setup will not work for me. As-is, the fan blows the hot air out the front of the case, but when the motherboard is installed into the arcade cabinet, the fan will not be in a position to blow the hot air out of the cabinet. I need to install a smaller, more up-to-date cpu cooling fan that will blow the air up into the cabinet, the fan that comes with the intel core-i5 processor or something similar would be ideal, then a larger fan will be mounted in the back of the cabinet, blowing all the hot air from the cabinet out the back, not just the hot air from the cpu heat sink.

I hope that made sense, I'll attempt to add pictures.

I bought a used Dell Optiplex GX620. I want to use my VGA monitor with it. There was a black plastic cap over the VGA port. I removed the cap and plugged in the monitor. When turning on the computer, the computer's power light comes on and I can hear the hard drive presumably booting Windows. But the computer is not sending a signal to the monitor apparently.

I checked the monitor with a Pentium III machine and the monitor works fine.

The Dell has a DVI video card installed. I do not own any DVI monitors or televisions. The VGA monitor is the only monitor I have.

Windows XP. Pentium D.

Answer:VGA monitor with Dell Optiplex GX620

Make sure you have the right output, if your computer has onboard video which most Dells do try that output, if nothing works remove the video card and connect to onboard output and restart the computer. The onboard output is higher up near all the other motherboard outputs, a video card output is lower in the pci card area.

If you wish to use the video card enter bios 'del' and disable onboard video in bios save and exit.

Can you confirm your using a VGA output with your vga monitor and not using a DVI to VGA adapter cable, if you have any HDMI displays or TV's you can test the DVI output using a DVI to HDMI adapter cable. Can you also post the model of the video card.

EDIT Have you had this computer working at all?

I found my old OptiPlex GX620 from the garage and decided to boot it up and see what cool stuff I'd find from there. Although I can't boot it up. I remember it had no issues before placing it to garage. This is what currently happens:It says that the battery voltage is low & previous fan failure.
Another issue is that it doesn't recognize my USB-keyboard (Gigabyte Force K85) (The compuiter doesn't have the PS2 port, although I have a PS2 keyboard as well). My keyboard's lights start up & the Num Lock stays on but I cannot press anything.
I have attached the images of the screen that appears.
Any advice is appreciated!

As a total DELL-Lover I only have such Machines around.
I just wanted to build up a OP 760 for my little son.

When I plug the power cort, the diagnostic LEDs 2 3 4 keep flashing while the power LED is amber.
System has only orgiginal DELL components, no add-on cards.

I checked out two CPU types:
intel E8600 and E7300

Also, I tried without any CPU - then, the diagnostic lights for a missing CPU light up.

I would be so perfect if there would be any solution for this.

Anyone knows how to fix that?

I have a Dell Latitude E5250. When plugging in the AC adapter the only light that comes on is the power button light and it's blinking continuously. The other indicator lights are off. The system board has been replaced, no change. After the system board was replaced the battery indicator light came on and the battery charged, though the laptop would not power on when the power button was pressed. It would light up then go out.  I've removed the battery and AC adapter, held down the power button to discharge flea power, no change. Followed Dell TechDirect directions to remove the battery and CMOS battery, then insert the AC adapter and power on the laptop, no change. I've tried known good RAM. I've removed all components including the LCD cable, no change. When the AC adapter is installed the power button light blinks continuously, no pattern, no other indicator lights come on. Any thoughts? I'm wondering if it's a video issue, bad Touch LCD?

Ok so there was a Dell optiplex gx620 small Form sitting around my house when a laptop I was using *** out. I put a Geforce 750 ti in it and added two 2 gb memory ram with the two 512mb that were already in it. So 5gb in it but has like 3.5gb limitation with windows xp 32bit. Also added a wifi adapter chip.
OK now that I'm done telling what I've added here we go. With the memory upgrade and the graphic upgrade I thought it would run super smoothly but nope, it's better but still too slow for things I'm trying to do. So I looked around and I'm thinking maybe even though I upgraded that stuff the computers processor  (cpu) is still not good enough and is standard old and sluggish and needs upgraded to bring this computer "to life"
SOOOOOO Straight and forward to the point, I need someone to tell me what the maximum best CPUpgrade for my Dell Optiplex Gx620 small form is. (Please no "this isn't worth it" comments) thanks.

what is the fastest intel core 2 processor i can buy for my dell optiplex gx620?it has a pentium 4 2.8ghz LGA 775 socket
I heard about the fsb bieng capped at 800mhz and wondered also if i could buy a dell optiplex board that supports intel core 2 or if their is any way to flash the BIOS to allow this

Answer:best processor upgrade for Dell Optiplex GX620

The GX620 doesn't support any Core processors. The chipset theoretically could do some of the low end ones, but the bios has to recognize the processor and then more or less let the motherboard adjust the voltage provided to the processor.
The best you can get is a Pentium D I believe. The first Optiplex with Core support was the 745 if memory serves.

Over the past month I installed two brand new 500 GB Western Digital HDD. They worked fine for a while and everything worked great until I came home one day and I turned on my monitor and was receiving an error. "SATA 0: Not Found" or something along those lines. It has been happening often since then and I am also having problems booting from my primary HDD. After a while I received a "Alert: Previous Fan Failure" error and it seemed my fan was ****ed. I took off the side panel and turned on my CPU and everything was fine, my fan was running and everything. After that I got another HDD not found error and took the HDD's out and they seriously were too hot to touch and they heat up incredibly fast and now everytime I use my system after about 20 to 30 minutes it freezes and ****s up, it has never had this happen before and my fan is still working. Here are my specs:

I have an old Optiplex GX240 that had its power supply break, I recently got another power supply from a different computer. The Power supply is working however there is an orange light on the motherboard and power button that doesn't flash. The ABCD lights on the back of the computer are also not lit.

Answer:Orange Light On Power Button and Motherboard - Dell Optiplex GX240

GX240 requires specific NON PFC power supply.  This unit is 16 years old now and has 512 meg ram of the PC133 variety.   A newer model like an optiplex GX620 or better is still viable.  This system is TOO OLD and TOO Slow to be of any use.

Hi, this is my first post and I have never used any other forum so i hope I'm diong things the right way.

I have a Dell Optiplex Gx280 and it won't start, an amber light is flashing in the power button. I have read the manual and it states the following:

If the power light is blinking amber ?

The computer is receiving electrical power, but an internal power problem might exist.

Ensure that the voltage selection switch is set to match the AC power at your location (if applicable).
Ensure that the processor power cable is securely connected to the system board.

I did both things but it still does'nt power up.

I opened the comptuer and the stand by power light is on, (the one in the system board). I don't know if this is ok.

What else can i do?

Thanks for your help.


Answer:Dell Optiplex GX280 won't start, amber light flashing

How long have you had this machine? Is it brand new? If so take it back. If it's not new, what is the last thing you did to your machine? Any modifications? You are not getting any signal. An amber light means it's running but it's not going to show up on the screen.

Hi !
I was given a Dell Optiplex GX620 SFF by a friend that was working ok, but...
I tried to install a PCI-e VGA card with HDMI with negative results.
After removing the expansion card, results were as follows:
Upon powering on the machine screen signal led turns instantly green (as if it gets some kind of signal),
but then returns to orange = no signal.
I unplugged the HDD and left only one memory stick on the board.
A series of beeps (3 followed by 2 was what i could identify) and then looked at the diagnostic lights.
Diagnostic lights 3,4 remained on with one ram stick of 512Mb Kingston @ 533 MHz
Diagnostic lights 3,4 remained on with one ram stick of 1Gb Kingston @ 667 MHz
Diagnostic lights 1,2,3 remained on with one ram stick of 512 Mb Transcend 512 @ 800 MHz
Diagnostic lights 1,2,3 remained on with one ram stick of 1Gb Supertalent @ 800 MHz
In the meantime i reset the bios following this procedure
which did not solve the issue.

I can not tell which bios version the machine has.

There may be a limit present in the BIOS (or by the SATA controller) for large drives. Aside from trying a BIOS update (which didn't work), you may be out of luck.

Try clearing the CMOS by moving the jumper and now my dell computer is making a beeping noise and wont turn on, What the heck did I do wrong? I didnt unplug it when I moved the jumper, would that make the computer not work anymore?HELP!!!

Answer:I have a Dell Optiplex gx620, I removed the jumper from PSWD to RTCRST

You moved the jumper without turning off the computer?
Why did you need to clear the CMOS?
Did you have a password installed that you were trying to remove?
What is the pattern of the beeps? How many beeps and what are the groupings?
We have a GX620 here which we may be able to use to trouble shoot.
Although I do not yet know, very often when you change jumpers while the computer is on and working, you can permanently damage the motherboard. But lets keep our hopes up.

GX620 won't  F12 Boot or work with windows 10 USB.  You have to use 32 bit only DVD and only after the region is set and the firmware is upgraded on the DVD drive.  64 bit windows 10 requires BIOS A11 and Pentium D 900 series from 915 to 960.  No point in doing this however since you can never use more than 3.5 gigs of ram.  2 Gigs is required minimum installed ram.

Can I definitely say it is the PSU?  If so, is the PSU from a 2400 interchangeable with this one?  If it isn't, are there particular brands I should look for or stay away from when purchasing a new PSU?

Thanks so much!

Answer:Dell 8400 blinking amber light won't start, no diagnostic lights

Blinking Amber means Bad Power Supply.

I don't have any version of Windows installed so it's not possible to run any diagnostic unless there are some Linux based ones.
Thanks for any help

Answer:Dell Optiplex 780 MiniTower, power light flashes amber diagnostic lights 1 & 3 flash

Blinking Amber power: Initial state of light at power up. Indicates system has power, but the POWER_GOOD signal is not yet active. If the Hard Drive light is off, it is probable that the power supply needs to be replaced. If the Hard Drive light on, it is probable that an onboard regulator or VRM has failed. Look at the diagnostic lights for further information.
1+3:  Memory modules are detected, but a memory configuration or compatibility error has occurred.
You could try resetting BIOS to see if you can clear the error.

Reboot and press F2 to open BIOS setup
Copy down all current BIOS settings
Power off, unplug
Press/hold power button for ~15 sec
Open case and remove motherboard battery
Press/hold power button for ~30 sec
Reseat RAM modules in their slots
Reinstall battery- good time for new CR2032 coin cell, if this one is old
Close case and reboot

If that helps, go back into BIOS setup, and confirm that all settings match what you wrote down. Be sure to save any changes before exiting setup.

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.

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

2. We are not 5, your title "and no worky" might imply you were talking to a baby and could very well explain why no one has replied to this post; they think your an ******* (and i tend to agree).
3. As for your problem, i dont understand what you mean by "I took my pc (laptop) to another pc that works ok" and you haven't given even close to enough info. Do you have a switch or router? is your network wireless? how many other PC's do you have? did you install a firewall recently? Its like trying to fix a car and all you know is that the car is blue.

What you need to do is determine what is malfunctioning first. You would do this by changing out computer/cables/etc. to find out which isn't working. For example, take a cable off of a computer that is able to connect - that cable is good - try to use it with your laptop. If that doesn't work try to connect another computer to what your laptop is usually connected to, if it works your laptop is most likely the problem. Come back after u have some info, and use the spell check and try to catch mistakes like "worky".

    I have read many many articles about the problem I am having but none of them have helped me to solve my problem. (probably because I don't understand them) But anyways here is the story of what happened. I walked into my office and saw that my computer was frozen. So I turned it off and then turned it back on but when I did it beeped three times and wouldn't turn on. I had no idea what in the world was going on so my dad told me to unplug the power cord for a couple days. I did so but when I plugged it back in and pressed the power button it did nothing. I looked at the back of the tower and there was a green light blinking on the back of the computer. I took off the case and I saw a light on the motherboard also blinking. I have no idea whats going on. Please help me. Oh and P.S. I am only 14 and know nothing about computers so please try and simplify your responses.

Answer:Green light on back of computer blinking/ticking

The green eight is not related to your problem. That is from the network thing. When the computer is plugged in, a very small bit of power goes to some things.It is possible that part of the Power Supply has gone bad. Or maybe a drive has failed and shorted out the power. Or, it could be the power switch has come loose.

I have a Toshiba M35 Satalite. There is a set of 3 LED lights just under the cover lock clasp. The one that has a power plug icon on it is blinking fast and the unit will not boot. I searched the manual but there is no mention of what this flashing light means. Could it be an exhaust or shorted out battery? I"ve had this unit torn down many times and have replaced the AC jack twice. Any help would be apreciated.

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.

Answer:Dell XPS 8700 Orange Light inside and Green Light on Back

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.

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

Try the monitor with another system.

What video card do you have? You mention XP SP2 & earlier XP versions work OK. How old is the video card?

- Reseat video card
- Make sure video cable is good
- Swap out video card; try another

The machine is a 4313-CTO, first generation i5 CPU, standard video, that suddenly died during a game of Spider Solitaire.Since the time was late I shut it down and unplugged for the night. In the morning I tried to restart. So did the computer, but it faltered and died. As I was about to unplug it I noticed the green cover light blinking about the speed of a calm heartbeat. Baffled by the new blink, I left it plugged in, but closed, and came back about a half hour later, hoping that by some miracle all was right again. Instead, I found the the cover warm, the keyboard very warm, the underneath hot enough that the Microsoft COA had started to detach, and underneath over by the W&D keys very, very hot. Right away I checked the battery, but it was relatively cool, so the heat was probably being generated by AC rather than DC. Now I am wondering where to go from here. I suspect some sort of catastrophic mobo, charging system, or CPU failure. If it is a mobo it will be the THIRD motherboard failure in ninteen months since new, which seems a bit excessive for a business-class computer. Does Lenovo offer a special price on a 6-pack of motherboards?  What would you do? By the way, the original mobo was replaced at four months by the repair depot in trying to fix a non-motherboard problem. The "dumpster-found" mobo they put in DID have a problem, because the computer would no longer start on battery. At eight months that mobo was replaced, also. Now I wonder if this... Read more

Kudos to you for a well written post.  Clever.
Agree that we shouldn't put 3 boards in a system - this seems abnormal & excessive.
Can you send me a PM with your contact information - name, address, best phone to reach you?  I'll also need the system model and serial # from the bottom of the unit.   Let's see what we can do.

My Dell XPS 15 9550 about 1½ years old started to act up a bit with a lot of "Your PC ran into problems and must be restarted" from Windows 10.
I tried to upgrade all drivers and firmwares as it was always hardware related.
Then all of a sudden the laptop didn't wake up after standby and when I pressed the power button it lit up and I could hear a very soft hum of the fans but nothing more happened, nothing on the screen.
I found some tip online to hold the D-button pressed to check if the screen was alright and when doing it the screen toggles over a few colors and then it just sat there again.
I found another tip to connect the charger and let it charge for an hour before trying again but that did no difference.
The next tip I found was to open it up and unplug the battery. Going to the store and bought a Torx T5 screwdriver and then used my credit card to open the lid (it is glued a bit) and remember the two philips screws under the lid on the backside!
Well, unplugging the battery and replugging did nothing, still the same.
The next tip I found which sounded rather odd but I had nothing to lose was to remove as many circuit boards as possible and "uncharge" them. I removed all "easily" accessible boards, HDD, memory and some other two small boards.
The next step according to the post I found was to make sure you are not carrying any static electricity so ground yourself through a grounded appliance, the water faucet or similar... Read more

Why would a computer take hours and days before a display? When the system is turn on very ofter the power light keeps blinking and the harddrive light is on but nothing shows on the monitor for hours or days and may not at all. Powering off and re-powering rarely helps it just have to be left alone and comes on whenever if ever.. Thanks for help

Answer:The power light keeps blinking and the harddrive light is on

Try a new signal cable from PC to monitor.If no change, try a new graphics card.If still no change, test the hard drive with "Seagate SeaTools for DOS".Click the "Download" tab here: download is an ISO file, so you'll also need to install "IMGBurn" from here: IMGBurn to create a CD from the ISO file, then boot your faulty computer from it. The testing program will open. Select the hard drive and test it. If it fails the test you need to replace the hard drive.If hard drive passes the test it's okay, so test the RAM modules with "Memtest86" which is also an ISO file, so you need to create a CD from that too:

Dell OptiPlex 9020 SFF 
system won't show screen, power led is white, cpu fan revs, but not loudly.
Dell Support were friendly & helpful but didn't get me anywhere, so it's DIY :-).
Power supply test (button on PSU) runs OK when turned off and PSU led is green, so not a power supply problem.
Shutdown and remove power for 1min - no change.
Disconnect HDD, AMD graphics card & DVD & one (of 2) memory module- no change.
Remove both DIMM, pwr on - system beeps - good motherboard is alive :-)
Disconnect power, remove last Memory DIMM & swap for the other one & system boots into BIOS Menu (as there's no disks to boot from)
Pwr down, connect HDD - Pwr up -no screen, no boot. (After this you're back to a dead PC agian)
Long story short - ONLY if you change the DIMM & leave ONE DIMM by itself THEN will system start, but not if any disks are connected. (if you only have one DIMM use Slot2 which works)

The green (power) LED on the front panel of my computer just recently started a slow (1 sec) blink. This occurs from the moment I power on and continues until I power down. I have a Asus A7NX8 Deluxe motherboard with a generic (Turbolink LC-A420ATX) power supply. It has been running for about two years with no problems. I don't believe it is a temp issue because the blink occurs the moment I power on. The voice POST reporter doesn't report any problems and boots normally. The computer seems to function normally. Is this blinking power LED trying to tell me something?

Hi Guys,

I have an old Equium L40 that I haven't used it in a while.

Now when I plug the power adapter in the power led just blinks green constantly.
I've checked the blink codes but I can't find one for mine. It simply turns green for a second and then off.
Then green for a second then off and does this constantly.

I've tried removing the battery for a few minutes and then holding the power button down for a minute, but I just get the same result. The power adapter is a the one that came with the laptop and as far as I can tell works fine.

Any other ideas would be greatly appreciated!

Thanks guys!

Answer:Equium L40 10X Blinking green power LED


Power Indikator (DC IN) indicates the power status with the AC adaptor connected.
The green (not blinking) means power is being supplied and the computer is turned on.
The power indicator on the front of the computer will glow green when the computer is switched on.
The blinking amber indicates power is being supplied to the computer while the notebook is in sleep mode.

Unfortunately, the DC IN green blinking status looks like a hardware problem.
Probably the power supplied to notebook is abnormal or there are some problems with power supply electronic on the motherboard.

By the way: please check the RAM modules. Remove one and test the unit using only one module in each slot. Check both modules.
Some years ago, a friend of mine has had some problems with the notebook. The blinking LED indicated the RAM issue

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 Inspiron 15R N5110 won't come on. I've tried both battery and 2 different ac adapters. I've removed the battery, unplugged it, and held the power button for 30 seconds to discharge the system, but it still won't come on.
I took the laptop apart and everything looks alright, but the DC jack was slightly brown on top so I replaced the DC jack board. It still won't work.
I made sure the connections are tight (the DC jack and other USB board) by screwing them down. The only thing that happens that shows any life is when the battery is in. The power button, power indicator light in front, and the little "gears" light blink white for just a moment, then off, about every 5 seconds.

Any ideas? If I have to replace the motherboard, what is the difference between 0G8RW1 and 0VVN1W? I'm not worried about the product key not validating - may even put Windows 8 on it.

My computer was down when I came back from lunch and could not get it to come back on.  If I hold the power button down for about 7 seconds it blinks orange but there is not noise from the fan coming on or post beep.  Also the green light on the back is not on either. All of the other equipment sharing the same power strip come on but not the desktop so it is not the power strip.  I also tried to set it up in another office on a completely different circuit and still does the same thing. What should I try next?

Answer:OptiPlex 790 Wont power on power light blinks amber

Which form factor, desktop, mini-tower, small form, ultra-small form?
From the (desktop) manual: Blinking amber light indicates a problem with the system board.
Are any of the 4 diagnostic LEDs on when it won't boot? ,They're on the front of the PC next to the power button. Look up error codes in the manual.
Possible power supply failure if the green light is off on the back. Can you try a different power cord? What happens if you push the power supply diagnostic button on back of PC next to that (green) power light?
