This method can be a bit tricky because different laptop brands have different buttons to get into System BIOS. So, better google how you can enter BIOS on your device. Once you have booted your laptop into the BIOS, you have to look for the “Main” or “Information” tab, as it varies depending upon the device.

If you didn’t find the serial number in the Command prompt then you won’t find it here either. However, the BIOS method can be helpful if you are not able to sign in to windows for some reason.

There’s always a sticker under your laptop. Flip over your laptop and try to find the serial number in the sticker. Some brands print the serial number on the metal or plastic base on the laptop. If your laptop has a removable battery, then don’t forget to check the battery compartment, you might find the sticker there as well.
