It’s always easiest if you’ve already removed the screen—especially for non-touch displays, as the screen label alone is usually all we need. If the screen hasn’t been removed or it’s a touch display, we may need the full serial number or model info from the device itself. This can typically be found on the laptop’s base, under the battery, or accessed through Windows settings. Follow these steps to get brand specific model number .
