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 http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)


Hi all, new here and not very technological so be gentle.
I have bought an old Optiplex 380 SFF to use for a homemade arcade cabinet project and need some wiring advice / help. Basically I want to add and illuminated arcade button to act as the power switch when the cabinet is built as the computer will be inside and not accessible.  As these computers do not have traditional headers / pins for the power switch I am stuck as how to achieve this. Looking at it I believe that the ribbon connector that connects the power audio USB front panel to the motherboard would be a good place to look, dell part number UM941. Ideally I would like to isolate the + and - for both the power switch and the power led within this ribbon. Does anyone have a wiring diagram for this part number? Or a pinout for the motherboard and the front panel? Motherboard part number is R64DJ and front panel is XW055

A:Dell Optiplex 380 SFF second power button and lower led

Dell doesn't make front panel wiring diagrams or the pin-outs public. So unless somebody else has mapped that connector, or you can do it yourself, you may be out of luck...
Will the keyboard be accessible once it's in your cabinet? If not, how will you exit Windows and shut down correctly? If you just push the power button to force shut down, you may create errors on the HDD that could prevent Windows from booting the next time. And any data not already saved will be lost.
Assuming the keyboard is accessible for normal shutdowns, here's a suggestion:
Look in BIOS to see if there's an AC Recovery option. If there is, you could set that to "reboot". Now you're free to plug the PC into a power strip or a switch box of your own design.  After the PC shuts itself down through Windows, turn off the power strip or press your fancy button to disconnect the PC from the AC.
Next time you turn the strip on or press your button, the PC will think it's recovering from a power failure. And with AC Recovery in BIOS set to reboot, it will automatically reboot the PC.
Sure sounds easier than what you're contemplating... 
EDIT: And if you plug your monitor, speakers etc into that same power strip, you only have to press one switch to turn everything on all at once.

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

Read other answers

When pressing the on button to turn on the computer, the numbers 3 4 appear above the power button along with a binging sound, or ringing sound and the computer does not boot up.
After waiting a while, I retired to boot the computer, the numbers then were 1 2 3 4 and the computer booted up just fine. I turned the computer off through the normal commands on the monitor and then attempted to turn the computer back on again. At this point the numbers 3 4 appeared and the computer would not turn on. 
Any clue, suggestion would be appreciated.

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.

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.

I have been using my Lenovo Y500 laptop for 5 years and there was no problem like this. Yesterday I got a new SSD to replace my hard drive and after some problems, I managed to install windows and started using it.However, there is a problem. When trying to open the laptop with power button, it no longer boots. It just gets stuck on Lenovo logo screen.The only way to get past this is pressing restore button, which opens something called Novo button menu Where I have to select "Normal startup" to start my OS. Which is kinda annoying.What could be the problem here?

Any assistance would be greatly appreciated. Thank you.

I have this problem for one week. I have the following error message when I start up my PC, a 6-year old HP pavilion desktop:

“Reboot and select proper device or insert boot media in selected boot drive and press a key”

Pressing any key gives me the same message. The night before the problem started, it was OK – however, I noticed that the shutdown process was much slower than usual.

I had done the following to try to resolve the problem but without success:

I had gone into the cmos setup / Boot Device priority and tried to set to boot from hard drive first but it indicates “HDD Group Boot Priority” as not installed.

In cmos setup, I pressed F5 key to Load Setup defaults, then F10 to save and exit cmos setup.
I took out the coin size battery from the motherboard, waited for 15 minutes and placed it back – then went into cmos again, press F5 again to Load Setup defaults. Repeated the process twice, this time waited for half an hour before putting the battery back – still cannot boot.

I took out the graphics card and put it back; unplugged the power cable from the hard drive and inserted it back; used another spare power connector to connect to the hard drive.
I pulled out (disconnect) the hard drive data cable (red color) from both the hard drive and motherboard and re-connect it back – still cannot boot.

And I realized something is very strange – now, every time I switched on the power on the wall plug, the PC start to power up immediately and the power ... Read more

recently bought a Dell Inspiron 14 5459 on June 12, 2016 and first thing I noticed is that to turn on the laptop I need to press and hold down the power button at least for 3 seconds in order for the laptop to boot up, this seems strange, I brought up this issue at the Dell Store where I bought the laptop and the sales people there told me that they noticed this in most Inspiron models.  Is this normal?

Hoping someone here can offer some advice? I own a Dell studio xps 435t-9000 that is a couple years old. I recently replaced my harddrive and since then (don't know if it's a coincidence or not) I'm having another problem. After I installed it, the first time my computer went into sleep mode/hibernation I couldn't wake it up. Power light was flashing white. Eventually I shut it down manually and then it wouldn't boot. Had a solid amber light, no power except the power supply. Fans not working. I unplugged everything and made sure it was all good. Wouldn't start. Left it overnight and plugged it in the next morning. Started up. Worked great for about 7 hours and then just randomly shut down, no errors or anything. Same deal. Wouldn't start, amber solid power light. Let it sit for awhile, reseated everything and wouldn't start.Gave up for awhile, tried a few hours later and it started. I read a few boards pointing to the power supply being bad or not powerful enough. However, I replaced the power supply about 6 months ago with a Corsair 600 which is plenty power. Could still be an issue perhaps but seems odd it would die in that little time. I also replaced my graphics card if that matters. Finally the last time I checked all the plugs I also took out the board batter for a few minutes to try and "reset" things. Not sure if that matters, either.

So, I'm at a loss where to go from here. I could replace the power su... Read more

I'm having issues with a Dell XPS 8500. The power button does not power on the computer at all. I tried the usual reseating everything including the battery and holding the power button in with no power cable. I ordered a new power supply and put it in but now realize it's for an 8700. The only difference is the 8700 psu has the test button and the 8500 doesn't.
If I hook up the computer to a monitor/keyboard/mouse and hold the test button in on the psu, the computer boots and functions as normal. If I let go of the test button it shuts off. Is there a way to turn the test button on all the time because that would fix it.
Is there a special way to test if the power button is broken? I unplugged the button on the board labeled F and I read something about using a screw driver to connect the pins to turn on the PC?

A:Dell XPS 8500 Power Button No Power

Thank you for confirming all the troubleshooting steps that you have performed.
Now to confirm if the power button or the power button cable is faulty turn of the system and disconnect the power button cable which is connected to the motherboard.Then power on the system by connecting it to the wall socket then connect a monitor to the system ,we are trying to power on the system directly from the mains.

I bought my Optiplex 9020 mini tower July 2015. It's been used and moved 7 times and on the last move, the power button became unresponsive. When initially plugged in, one Amber blink shows up on the power button, and no more. I've held the button and nothing. However, if I hold the button on the back of the computer on the power supply, while holding it for 30 seconds, the power button works: I can turn on the computer and log in. Everything shows up alive and well.
Dell support sent me a replacement power supply thinking that was the issue. But even after replacing it, the same issue occurs. One Amber blink on the power button when pressed and held. No more. And again, the computer starts when the back power supply button is held for 30 seconds and the front power button is pressed. The power only turns on while the back power supply button is pressed. Is this an error with the power button or the power cable? When on, there are no problems or error messages.
Any help would be great!

Has anyone else with this model been experiencing issues with the PC shutting down, and then blinking orange amber light on the front?
We have 100 of these and had this problem on a few of them. The blinking pattern is 2 then 1, which Dell says is system board failure. But resetting the power fixes it till it happens again. The first time it happened we replaced the PC, and the same thing happened. So we replaced the power adapter, and the same thing happened. Then we took a whole new PC out of a box and finally that person didnt have the issue again. But now someone else is.

My Dell GX300 won't power on. The power button light just blinks when it is plugged in. I tried booting from a floppy and from the OS disk but nothing happens.
Any suggestions would be greatly appreciated.

A:Optiplex GX300 Blinking Power Button Light

It's either a bad power supply or mainboard -- the former more likely than the latter.  Unfortunately, both the power supply and mainboard are both proprietary and obsolete on this model - you may have difficulty finding either.
Unless the system can't be replaced for some reason, that would be preferable than the seach for parts for this one (which is on the order of 15+ years old).

Hi everybody,
I recently inherited an unused PC from work. It's an Optiplex 780 with a faulty power supply.
I replaced the power supply with a working one from an old Optiplex 740 and also had to buy an standard ATX 24 pin to mini ATX 24 pin cable in order to use the 740' PSU in my Optiplex 780.
I have plugged in the power cord (but no mouse & keyboard because I don't have any USB keyboard available) and I expected the computer to show DELL logo as well as on screen POST messages during power up but instead I can see the following :
1) Power button in orange color. No blinking. : according to service manual it means PSU is probably OK and PC has reach booting stage 2.
2) 1,2 & 4 green diagnostic lights are on. This combination (1,2,4) is not listed in service manual so I have no idea on the possible kind of error.
Any suggestions about the possible error and how to fix it?
Kind regards,

Hey,Dear i have problem with my desktop dell optiplex 9020 the problem is when i tried to power on it is not powering on but i can see that the power button is still orange but it is not powering on.

A:Power issue with dell optiplex 9020

Hi ,
Thank you for writing to Dell Community Forum!
Here when the power button is  orange it indicates that the system is receiving power but not sufficient power to transmit it to the system's components.
However I would suggest you to try these steps and advise the result ,
*Disconnect the system from wall socket and press ,hold the power button where in we are releasing the static charge from the system ,then connect the system back to the wall socket and turn on the system .
*To confirm if the power supply unit is working fine would ask you to perform the power supply unit Built in self test where in behind the system where the power cord connects to the system you will be able to see a tiny black button with a green radial bulb next to it .When that button is pressed if the green light glows then power supply unit is working fine.
*Confirm the power button has a steady orange  light or blinking orange and also if you hear any beeps from the system .
Can you also provide your computer model ,service tag of the system (via private message) to perform model specific troubleshooting. Hope to hear from you soon.
Have a great day ahead !
Kindest Regards,

So, my boss wants a remote power switch added to his Dell OptiPlex 7020 so he can pack it away in a cabinet but still be able to turn it on remotely, comfortably. I have no idea what the pin assignments are, pins look like this (box on side, front facing you, plug is in lower right corner of box):
Left to right top row first:
Yellow, Red, OrangeBlack, Blue, open     * * *     * *Any ideas that will not short me out?Thanks.

A:Dell OptiPlex 7020 on\off power pin assignments

Dell doesn't make those pin-outs public. So unless somebody else has or can map them for you...
But I've got 2 cheaper / easier suggestions.
Option #1:

Connect PC to a surge protector or power strip with its own power switch.
Reboot and immediately press F2 to open BIOS setup.
In BIOS setup, set AC Recovery to "Power On". Save the change and exit setup.
After using PC, shut down normally in Windows
Turn surge/strip off at its own switch
When you turn surge/strip on again, PC boots automatically without pressing its power button
If you connect monitor, printer, etc to same surge/strip*, they all power on with one switch
*NOTE: Surge/strip must support the load of all devices powering on at same time

Option #2:

In BIOS setup, set the Auto On Time options to suitable days/times; instead of using the AC Recovery option
Less "flexible" than using the AC Recovery option and requires user to turn monitor etc on separately

Give your boss the options, and pat yourself on the back for solving the need so simply .

Is there anything I need to take into account (connectors etc.)?

I'm new at this and would greatly appreciate any help.

Alright so normally I can fix any pc issue I come across but I have very little knowledge of AIO's
Client called me with a Optiplex 9010 All in one.
When plugged in the light next to power is green.
When you hit the power the power light goes blue and the  light above the power is white for 4 seconds.
Fan starts up for 1 second and nothing else happens. nothing on the screen at all  (normally)
sometimes when you push the power the fan starts for a second then dies then for the next few minutes it trys to start with fan going from 1 second then dead, fan for 2 seconds then dead, fan goes 10 seconds and then dead,  almost like a car engine not getting gas but trying to start up.
Whole time it does this the power light stays blue and the light next to the plug is green.

My guess is a bad capacitor on the mother board or a bad PSU.  This being a AIO I would have to order direct from dell or off ebay.  So would like some more info being putting another $100 into a brick
