All Dells have a Service Tag (like a serial number) on them. For that model, it will be on a sticker on the bottom, possibly under the battery. If you can find it, write it down.
Then, go to Dell’s, website here: https://www.dell.com/support/home/en-us/product-support/product/latitude-e5530/overview
If found the Service Tag I mentioned, type it into the Dell website. This will give you all the system’s details, including how it was configured when it was originally built.
Regardless, all of the Dell software mentioned above can also be found on the same website, two tabs over. Or here: https://www.dell.com/support/home/en-us/product-support/product/latitude-e5530/drivers
Finally, this is everything you’ll likely need to dial that Dell back in (also on Dell’s website) https://www.dell.com/support/article/en-us/sln284879/dell-latitude-e5530-system-guide?lang=en
