Re: Service tag
I have Dell Inspiron 15-3521 purchased in 2013 and I am not able to locate service tag or express code. Service tag on the laptop back is not legible. Bios is not showing the same and dell assistant is reporting null service tag. I have replaced my motherboard two back.

What does that mean? BIOS does not display any Service Tag?
Service Tag is stored on motherboard. As you replaced the motherboard, the original Service Tag is gone. I don't know why it now displays nothing, but it wouldn't be valid anyway.
Why do you need the Service Tag? Your system is long past warranty. If you need drivers that are not provided by Windows Update (most are), you can download them from Dell Drivers & Downloads site. Just use the Manually find a specific driver for your Inspiron 3521 option. Listing updates based on Service Tag isn't reliable anyway, as it lists many drivers that aren't applicable to your system and misses many that are.
