Hi RAYB871,
Please check if there is any damage on the machine. Check if all the ports on the machine are fine or misaligned. Sometimes if the pins in the USB ports are touching each other, they are known to cause many issues on the machine.
Three components cause this issue, in this order:
Adapter - you have already tested another adapter, so ruled out.
DC Port - the port that holds the adapter in, might be shorted - you would need this part - http://bit.ly/2bQ3HoP
Motherboard - I would primarily suspect this part, if the dc port does not fix the issue, then it is the motherboard that has failed and needs to be replaced.
If there is no warranty, then you could contact our team to get a quote for a paid service call - http://dell.to/1vnT6CQ
Personally, I would suggest, you invest your money on a new machine than to repair this old machine. However, it is your discretion.
Also, please click my DELL-username and write me a private conversation with the service tag and your contact details(Name and Email) for case records.
Let us know if you have any other queries.

Hi there,

We've got 3 Dell precision towers 5810 that work great, except for a possible bios bug, which I can reproduce on all machines:

I'm using the installed NIC: Intel ethernet server adapter i210-t1.
Our computers go powerless every night (mains power) after a normal pc shutdown. Every morning, when the power is back on, I want to wake up all computers in our building with Wake On Lan (WOL) by sending a 'magic packet' over the network.
This normally works well if the machine has been switched on and off with the power button / windows shutdown. But when I unplug the machine (mains power), wait and plug in the mains power again, the computer does not respond to the WOL packet. (Maybe the PCI-E NIC does not get power on plugging in the mains of machine for the first time).
It works well on the integrated (motherboard) NIC. BIOS / power / sleep state settings seem to be ok.

Until very recently all was fine but somethings happened and now the audio is being compressed. I only noticed it about 2 days ago but it might have been doing it for a bit longer than that, I can't be sure. It's nasty and kills the life in music.
I wonder if a Win10 update has screwed the audio up.
I've checked all the settings I can think of and they look good.  I wonder if it's the Dell audio Maxx Audio Pro that came with the PC.  It looks like any eq or dodgy settings are disabled but it's just the sort of add-on that might cause problems. I think I may have had to switch settings off here when the PC was brand new to get it sounding right....but that might be a flawed memory.
The realtek driver says it is up to date and hasn't been changed since 2015

We have no issues with Wake on LAN (WOL) with our Dell OptiPlex 3010 machines, but I cannot get our Dell OptiPlex 3020 machines to boot in the same way.
In the BIOS I have enabled WOL and PXE booting as follows:
System Configuration > Integrated NICEnabled w/PXE is ticked
Power Management > Wake on LAN:LAN with PXE boot is ticked.
If I send a WOL signal, without PXE, I simply want to boot the machines normally into Windows, the 3010 machines will wake and look for a PXE server, when none is available, they will exit boot from LAN and boot from disk. Which is how I want it to work.
But the 3020 machines - which are set up as close to identically as the 3010s as possible - will also wake and look for a PXE server, but when none is available they will ask for a key to be pressed before they will boot from disk.  That's no good; I want them to boot into Windows (without user intervention) if there's no PXE server available!
If I set the 3020s to simply "Boot from LAN", then sending a WOL signal will correctly boot them into Windows. But that's no good either, as I want to have the option to PXE boot the machines remotely from time to time, as I want to be able to re-format a whole room of PCs using SCCM occasionally.
Does anyone know what the correct BIOS settings should be, to get the same result on the 3020s that I get on my 3010s?
Thanks in advance.

I recently noticed the battery was around 50% when I last used it. I thought my wife forgot to plug it in so I plugged it up. The next time I went to use it, I noticed it was a little lower, but I had removed the plug from the wall. I assumed it was the power adapter, so I ordered a new (OEM) unit directly through Lenovo. It made no difference, the computer does not charge or recognize the power adapter is "plugged in." I tried some online solutions and verified conservation mode was off. I also performed a battery diagnostic test and it found no issues. I tried holding the power button for 30 seconds and while I did hear the fans turn on shortly, it didn't change anything. I also tried the NOVO button, but it did not seem to do anything at all. Lastly, I even removed the bottom casing cover and pulled the battery for a few minutes, but again not change. My battery is now extremely low (using my way older HP unit now) and not sure how much more I can do without depleteing the battery where I cannot power it to make any changes. Is there any other way to power it besides the AC adapter?Any suggestions on what is going on? Could it be the charging circuit on the battery? I don't want to make another assumption and replace the battery if there is something that will prevent that battery from charging as well. Thanks,Kevin

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 .

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,

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.

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
