The laptop screen model number is found at the back of the LCD panel itself. However, some laptop manufacturers provide an alternative way of finding what LCD is installed in their machine.

Every Dell laptop has a Dell Service Tag, or a Dell Express Service code at the bottom of the case, and using either the Service Tag, or the Express Service Code you can use the tool on Dell’s support page. The beauty of this feature is that Dell enables you to see all the components and peripherals of the laptop without having to tear it apart.

After you enter your Dell Service Tag or the Express Service Code, proceed to “System Configuration”, then to “Components”. You will then see a list of all components installed in this laptop; and the part number of the component will be provided. Usually, the LCD will be marked as “LIQUID CRYSTAL DISPLAY” (use CTRL+F to search the page if you are on a Windows PC, or Command+F on a Mac). Now that you have located the part on the page, you have two options:

1. Copy the part number, and search it on our website [recommended];

or

2. Copy the part number, and use a search term of your choice to look up the specifications of the part; then use the specifications to reference and locate the correct part on our website;

Resolutions are coded by the following parameters:

HD or HDF = Standart High Definition, WXGA 1366×768
HD+ = High Definition+, WXGA+ 1600×900
FHD = Full HD, 1920×1080

    I would like to add the service tag number to my spreadsheet for my 450 Dell Chromebooks but cannot get my laser scanner to scan them without scanning the restore defaults under Barcode set up after each scan. Can you help me with this?

      I am not certain if this is the correct answer to your question, have you tried using blank paper and cutting out sections to cover the areas you do not want scanned?

    Another method is if the serial number is combined with the product number then use an equation to grab the serial number. For example only; “0123456789lrt0fn2” is the output from a scan. The serial number is “lrt0fn2”. Then use “=right(a1,7)” which should then output “lrt0fn2”.

      Thank you for the great suggestion Mikewaver.

      My laptop won’t work it keeps having a box appear saying service key it wants me to type it in. i have a Dell inspiron 15 laptop computer i bought 1 year ago. Where do i find this information? Or do you have to pay for another service key?

        You should have a sticker on your laptop with the Service tag or express service code. However if it is asking for a service key you will need to contact Dell directly for this issue. https://www.dell.com/support/home/us/en/04

    Hello,
    I am searching my dell laptop serial number. I am confusing in service tag, express service code and is express service code same as serial number? Please help me.

    1. LaptopScreen.com

      The Dell service tag and Express service code is not the same as the serial number. You will need to look on the laptop for these words and associated numbers. However if the laptop was bought used or refurbished these indicators may have been removed.

      If you cannot locate the service tag or express service code you may need to contact Dell directly https://www.dell.com/support/home/us/en/04 or remove the screen from the laptop and search our website using the screen model. https://www.laptopscreen.com/English/section/Articles/1245191276/Determine+your+LCD+screen+model+number/
