Serial number of your laptop is also the service tag of it. It is a 7 digit tag located at the bottom part of your laptop...

    In case if your service tag got erased/torn/invisible in the bottom of your laptop yo can always do this:

    Step1:Turn on the laptop,while laptop is booting(ie., when you see the dell logo on the screen,press F12 to enter into boot menu(as you have not mentioned your model,mostly you can see the key that you need to press to enter the boot menu on screen while system boots up).

    Step 2: Go to Boot Setup,use arrows on your keyboard to navigate and press enter

    Step3:In the first tree itself you will see system info,where you can see Service Tag,Processor information and other details

    Step4:Note down the service tag and then now press Esc to exit out of the menu,now you will be asked to exit or not select exit and press enter,you will be taken out of the boot setup and system restarts.

    Note: Don't change any options in boot menu unless,you know what you are doing,if you have changed any options in the boot menu,you will see do you want to save changes/not when you are exiting out of the boot menu,in case if you have involuntarily committed any changes,you can always restore them to Default by entering boot menu and selecting the Default options and committing the changes.

    I hope this helps you,even if your service tag sticker wipes out of the laptop.

You do not use the serial number to your laptop. You need the serial number for the software. It should be on the disc it or the box the software came in.

Hello kenneth702,

The Laptop serial number should be on the bottom of the laptop computer. If you need some other serial number it would be helpful to know what device the serial number is for.

Serial Number Issue

The only Serial that I know of that should be asked for is the Windows Product Key, This should be on a microsoft sticker on the underside of your laptop, if it is not there check your documentation as it may be there instead.
