How to Find Your Laptop Model Number Before Buying Spare Parts

The fastest source is the sticker on the bottom of the laptop, which lists the model name and often a product/serial number. If the sticker is worn, the model also appears in the BIOS/UEFI setup screen and in the operating system: on Windows, open System Information (msinfo32) or run “wmic csproduct get name” in Command Prompt.

Write down the full model string, including any suffix (for example “15-da0326tu” rather than just “HP 15”). Small suffix differences often mean different parts.

For batteries, screens and keyboards, the part number printed on the component is the safest identifier because one laptop model can ship with several variants. Read the battery part number on its label, the panel code on the back of the screen, or the keyboard variant details, and match that.

When you have both the laptop model and the component part number, ordering the correct compatible part is straightforward — and you can send both to us to confirm before packing.
