DMI System Serial Number 6ST6211 DMI System UUID 44454C4C-53CB6C0-4F323131 DMI Motherboard Manufacturer Dell Computer Corporation. Dell Inspiron 15 5570 Motherboard Main System Board Intel® Core™ i5-8250U NM2C6 We’ve carefully tested this pre-owned item; it is in great condition and guaranteed to work 100%. We test every item we sell twice, first when it enters our inventory and second before we offer it to you on eBay. I just replaced the motherboard in a Dell Inspiron 1440. The last step in the Dell Service Manual is to enter the correct Service Tag within BIOS. When I started it up and hit F2 and the section with the service tag could not be changed. Is there another way of changing the service tag to the correct one.
We recently had a motherboard changed on a Latitude D630 and then discovered some funny things happening in spiceworks. The laptop was being reported as an OptiPlex workstation instead of a Latitude laptop and the warranty info was incorrect. After looking into the problem I discovered the Service tag in the BIOS did not match the service tag on the bottom of the laptop and that is why information was being reported incorrectly. After being on the phone with Dell (and trying to use the asset application to change the service tag) I was told that the motherboard had to be replaced and the tech would put on the correct service tag. This didn't seem right to me as the system was working perfectly otherwise, so I did some digging on the net. Here is my solution.
Update: this 'How to' is quite old now and seems not to work on newer models. Some people have had luck with finding newer Dell diagsnostic cd images or see this article:

9 Steps total
Step 1: Download the Dell Latitude and Inspirion BIOS Upgrade and Diagnostics CD
I found it here:

THIS LINK IS DEAD....try this instead
http://pcemporium.webs.com/Dell%20Bios%20Reset.iso
it's not the same software but works....
Step 2: Unzip the file and burn the ISO to a cd
Unzip the file using winzip or 7-zip and you will end up with a file called Dell Portable Bios and Diags Rev A34.iso. Use Nero, Roxio, Image Burn (whatever program you might have) to burn the image to a cd.
Step 3: Boot from the cd
Stick the cd in the laptop and turn it on. Hit F12 at the DELL logo and you will get the Preparing one-time boot menu ..... choose CD/DVD/CD-RW Drive.
Step 4: Choose a selection
The cd will boot up and give you 4 options to select from. Choose option 3. Run the Service Tag Utility
Step 5: Erase the current service tag
It will come up and warn you that choosing yes will erase the asset, owner and service tag. Luckily we don't use either of the first two fields so I just choose yes and hit enter. If you do use asset and owner info in the BIOS I suggest you write them down first.
Step 6: Enter in the correct Service Tag
It will then erase the incorrect service tag and ask you to enter a new one. Enter in the correct one and hit enter.
Step 7: Verify the Service Tag
It will ask you to verify the service tag. Enter in the correct service tag and hit enter again.
Step 8: Are you Sure?
Motherboard Serial Number Search
It will ask you if you are sure you want to change the service tag. Choose yes
Step 9: Operation successful
It should tell you it was successful. Remove the cd and reboot. Your service tag is now changed. I tried rescanning the laptop in spiceworks but alot of the info was still messed up so I deleted and scanned the network... from there everything was fine.
I hope this comes in handy..

Usually the tech that does the replacement updates the bios and the service tag. Nice to have the utility just in case he forgets!
Thanks

Great research job! Thanks for share.

I used this and it made for an easy tag fix.

You CAN use the asset utility to change the service tag. It is an undocumented switch. run asset /s SERVICETAG, where SERVICETAG = the service tag you want to enter. Works like a charm on Optiplex & Latitude.

I basically wrote this how to because I could not get the /s to work. The Dell tech had me download a few different versions of asset from their website but that also failed using the /s. This was the only way I was able change the service tag.

With all due respect to John's how-to, the link in that post does not work. I was able to find another link outside the community with an ISO that works for Latitude (I only tried it on D620, D830, and E6400). It does not appear to work for desktops - at least not the GX520 or GX745 models.
Here's the link: http://pcemporium.webs.com/Dell%20Bios%20Reset.iso
I found it under the blog: http://forums.mydigitallife.info/threads/19369-Dell-Bios-Editing-Removing-Bios-Lock-Changing-Service-Asset-Tag-Software-Here
I burned the ISO to CD, booted from same and it worked perfectly.

Thanks JFMAN.... I'd been unable to find a new link but yours works fine :)

It’s quite frequent that we ignore some key things that we should be aware of. Possibly, it’s for our idleness or less interest about the topic. But how many times do we need to know that ignored things? Several times! Most of the problems that raise for ignoring these things are gadget oriented. Just try and imagine, the supreme devices that give us ultimate pleasure every time can cause headaches. Understandable that we’re fond of those which is the main reason behind a headache. So, in that miserable condition, what kind of knowledge can ease your brain? It’s, of course, knowing the serial number of our damaged device.
The uniqueness of these numbers is thereto separate identities of the same type of products. You can take the serial numbers and the model numbers as identical. But in reality, these two have a slight difference between them. The model numbers of two products can match, but the serial numbers are specified. By the serial numbers, you can easily isolate your device or any part of it. One can also be confused by merging its concept with UPCs. Despite being common, the UPC, ISSN and ISBN codes are not as distinctive as the serial numbers.
If the processor is the brain of an electronic device, then the motherboard must be its grey matter. Being the main PCB in any system CPU, a system board helps it to communicate with the other functional parts. Motherboard literally works as the supreme component in any gadget by allowing many cards to customise its variety. Is that all for the baseboard to be the most crucial part? No, my friend! It controls all the exclusive features and secures the electricity (static/dynamic) connection by any means. So, it’s natural that this necessary board do need to have a unique identity. Here, the serial numbers of motherboard come to play. Every company that manufactures motherboard like Acer, Asus, Dell, Intel, etc., are very sensitive providing the serial numbers into their products. As an example, the serial number of a system board can be seen like this ‘63012T92900849.’ No other, I repeat, no other motherboard serial number can match this one.
As I’ve discussed previously, problems can arise anytime without warning and to communicate that with the manufacturing company through their website; you must know the unique identity number of your motherboard so that they can track it easily. On the flipside, you should know the serial number and model number to upgrade your installed drivers. Though it’s not frequent to buy a defected item and end up being a victim, the serial numbers can be essential in these cases too.
You must be thinking why I haven’t mentioned the process of knowing the serial numbers yet. Don’t worry! I’ll clear all your queries. So, you can check the serial number of your motherboard by using command prompt, System information tool and an external software. Now, you can the steps or detailed method in Layer point.
Who wants to expend their money on some small worries, generated in their system? I bet, you also don’t want. Hence, all you need to do for that is to be aware of the unique numbers of your daily used devices.
