OptiPlex 790 SFF need service tag

I bought an Optiplex 790 SFF skeleton and found out that it doesn't have a label service all over her. How can I get a serial number for it? I can from Dell?

Latest version of the BIOS for OptiPlex 790 is here. Serial number shouldn't matter...

Read and follow the instructions carefully and turn off anti-virus suite first, if you install it in Windows.

Keep in mind there is always a small chance a BIOS update fails and kill the motherboard. So upgrade at your own risk...

Assuming that ST has not been removed from the BIOS, you should be able to find by using the free version of Belarc Advisor.

EDIT: ieee488 types faster as I do!

  • Power supply Dell Optiplex 790 SFF cycles power on and off when it is plugged

    My new to me SFF Optiplex 790 does not start - pressing power causes a switch to send amber for a few seconds, the 1 + 2 diagnostic lights shine briefly, and then the system turns off. But wait... with power plugged in, it will try to restart every 10 seconds or until I have unplug the unit.

    System lasted about 30-40 minutes when I tested it, but it starts then power cycling.

    Power supply passes with built-in 'green light' regardless of any internal or external devices connected. I bought a sweater 'work' PSU, no change.

    Ideas for testing? System is stock, no mods or upgrades of what I see.

    Hello

    This system is out of warranty period so that any replacement of parts will be payable. That's why we can help you with the replacement of the part by sending the request for quote for parts and service or, Alternatively, you can buy the part of any provider of local service from dell.

    Serial number of the system also has information on the customers system so donot share it as a public message, send it out via private only message.

  • Need a video card compatible for Dell Optiplex 745 (SFF) - help, please!

    I have a Dell Optiplex 745 SFF. The details of the standard can be found here: http://www.dell.com/downloads/global/products/optix/en/opti_745techspecs.pdf

    (even once, look at the MFS)

    I want to get the best possible video card for this PC that I can find, and I was hoping someone could help me with my options. I am aware of my options are limited, but I'd like to work with what I have here. Thanks much for any help.

    Sapphire 7750 is the best low profile card I know. There is no need of current auxiliary and is compatible with your power supply.

    SA makes a 7750 as well, but it requires more space and I don't know if it is compatible with your frame.

  • How do I know what motherboard I have service tag

    I have a number of computers dell, optiplex 380. 780 and 7 optiplex 760 upgrade the processor with four cores, if possible, but I find that each model has 2 motherboard ' possibilities, how do find out what motherboard, I have the service tag, and if they can take the quad cores. As I understand it a motherboard can take single core dual cpu and motherboard, it is possible to upgrade to a quad core cpu

    There is no such thing as serial number based on the motherboard.  Serial numbers are unique.

    SFF and USFF power supplies tend to be too small.

    The NDP or DELL of the Board part NUMBER is on THE Board of DIRECTORS and is not connected either to the

    SERVICE TAG which is the same as the serial number.

    Carrots or not is TOTALLY NOT related to the service tag Associates to the power supply and other factors.

  • OptiPlex 790 Mini-Tower bi-ecrans?

    I have an Optiplex 790 minitower with Intel HD 2000 integrated and i5-2400 video.

    The case has a VGA and Display Port connector, I am currently using the VGA port. I am a student going for a Setup dual monitor and am confused if I can do without having to buy a discrete video card. I read conflicting reports that some say Yes and some do not. Can a kind soul please one way or the other?

    I do not use the PC for games, it's a casual work with video and web browsing. I need mainly two monitors for editing multiple files, scripting, programming, database etc..

    Many thanks, flipper.

    Hi end,

    Embedded video solution of OptiPlex 790 is VGA and DisplayPort compatible at the same time. You can connect two monitors to the computer without adding a discrete card.

    Please let me know if you need further information.

  • Insect caught in the monitor u2414Hb and support is a disaster. No service tag

    First of all the question I seek to solve. A small insect, probably a fly has managed to make its way into my monitor in any way. It became lodged between the Panel and an outer layer or in the Panel and quickly dies. And has been stuck in place for more than a month. Attempts to dislodge without disassembling the monitor failed.

    Now, AFAIK disassemble the monitor to clear it will void the warranty and risk of damage to the screen so I prefer to avoid. I decided to contact the Department of support or guarantee dell to see if we could do something on this end.

    The monitor was purchased new from NewEgg.com on 01/01/15, with an indicated 3 years manufacturer's warranty. So, it should always be in the manufacturers warranty period.

    Although none where Dells website, or via their telephone system you can contact the technical support or departments without a number of warranty service. My monitor does not have a serial number, and Dells own materials state clearly that stand-alone monitors sold prior to 2016 (like this one, in 2015, has bought manufactured 2014) do not always have a service key.

    I tried every number on my monitor and its box, both online and telephone assistance. A number search as a service on the Web site key (but not with the telephone assistance) and appears as a system of office since 1997.

    Telephone service has been terrible. Repeatedly asking a service key, even when I explained that I don't have not one. Repeatedly ask me about Dell computer system I bought it, despite my clear statement that my problem was equipped with a screen of stand-alone and that I was not the owner of a dell computer system. Repeatedly asking me a Dell order number, despite my stating clearly it was not purchased from Dell, but bought new from newegg.com. Repeatedly telling me to contact the seller (newegg) to some how get help as a guarantee of the manufacturer. They told me a serial number was unnecessary because millions of people had bought monitors with this serial number. As if this makes no sense at all. I was told that a product model could be used to find what product I was calling about. I was told no numbers appearing on my device, or on its original packaging (that I kept) could be found in any system. I was transferred to several operators in several services all followed the same scenario and giving the same spiel on the * service tag. Before an operator involved, I've been dishonest and has asked for my phone number. All this despite the pages of Dell support stating clearly that some of their products do not have a key support.

    It does not appear to be process at all to deal with Dell products manufactured and sold without this little number that supposedly so critical. Dell apparently cannot do anything with the model # and # series uses all manufacturers in the world.

    . Exactly how to make contact with the service the customer without a service key.

    And can do something about the dead bug that introduced itself in the center of my screen as a brown spot little? Or am I stuck risking the destruction of my monitor with a canceled warranty? It doesn't make sense that a bug should be frankly worm its way between the layers of the screen.

  • Service Tag #*-595

    Hi, I am having a problem with a notebook dell studio 1535. when starting, get a mensje that says: This computer system, # ******* - 595B, is protected by a password authentication system. You can not access the data on this computer whithout the correct password.
    It would appear that the message is hard disk lock, but when connected to another computer I can access my data, I mean that is not locked the disk.
    What would remain to be password bios, but because it comes off as service tag # ******* - 595b? if the bottom cover of the notebook contained 4CMXWG1 Service Tag and express service code 9471256705. The error asterisks makes me think that the bios has a problem because no change was made immediately before leaving this error. From one day to another failure and leaves no longer start Windows.
    Anyone have any idea that might be happening? no way to flash or update the bios without either from the application in Windows? From already thank you very much, I will be attentive to any response.
    

    You will need to place a phone call from voice of Dell support.  Be prepared to check the details of your property.

  • Add the second hard drive in the Dell Optiplex 780 SFF

    Hello

    I have dell Optiplex 780 SFF (Small Form Factor) PC. It has 3 options of SATA. I want to add 2nd hard drive in it, but I see no power for 2 hard drive cable.

    At the present time, I have a SATA Hard Drive and a SATA Super Combo. But the power cable from the SATA Super combo is very unique, I can not able to give the power of this cable to my 2nd hard drive.

    Is it possible to add 2 hard disk in the PC case?

    Best regards

    Dani

    Hi Dani,

    The SFF is using a drive slim lens that does not have a standard SATA power connection. You will need to buy an adapter or a SATA power cable splitter to power a second hard drive.

    Use the RW - any program to display your embedded system locked preinstallation key BIOS:

    http://dellwindowsreinstallationguide.com/a-clean-install-of-Windows-8-1/Microsoft-product-activation/obtaining-your-OEM-BIOS-embedded-SLP-product-key-using-RW-everything-OEM-only/

    If your product key is rejected by the installation media and then probably the product key is for Windows 8.0 and media are a .iso Windows 8.1. Unfortunately made Microsoft the installation of deployment of the ridiculously difficult Windows/Windows 8 Service Pack1 8.1 causing much frustration users.

    To overcome these difficulties, you may need to install with a generic product key:

  • RAID0 en Dell Optiplex 790

    Buenas tardes!

    Estoy queriendo usar una Optiplex 790 como backup servidor, por lo that I need armar discos in RAID 0, y queria Saber TR are posible. Porque por lo than Biogen verificando via not web, none are posible.

    MUCHAS Gracias!

    Hi GFurlani,

    It is my understanding that the Intel Q65 chipset does not support RAID. If you need to add a separate controller card that supports the data disks in a RAID.

    Good luck!
