Methods to Find the Laptop Screen Model Number
There are several ways to find your laptop screen’s model number, ranging from the simple to the slightly more technical. We’ll cover them all, so you can choose the method that best suits your comfort level and available tools.
Checking the Physical Screen (Most Reliable)
The most reliable method is to physically inspect the screen itself. This usually involves disassembling the laptop, so proceed with caution and only if you’re comfortable with basic electronics repair.
Safety First: Disconnecting Power
Before you even think about touching a screwdriver, completely disconnect your laptop from the power adapter and remove the battery. This is crucial to prevent electrical shock or damage to your laptop’s components. Consult your laptop’s manual for specific instructions on battery removal, as procedures vary between models.
Disassembling the Laptop Bezel
The bezel is the plastic frame surrounding the screen. It’s usually held in place by plastic clips or screws.
- Carefully pry the bezel away from the screen. Use a plastic opening tool (spudger) or a thin, non-metallic object to avoid scratching the screen or bezel. Start at a corner and gently work your way around the perimeter.
- If you encounter resistance, check for screws hidden under rubber covers or stickers. Remove these screws before continuing.
- Once all clips or screws are released, the bezel should come off easily. Be gentle and avoid forcing it.
Locating the Model Number on the Screen
With the bezel removed, you should be able to see the back of the LCD panel. Look for a sticker or label containing the model number. It’s usually a combination of letters and numbers, such as “B156XW02 V.1” or “LP156WH4 (TL)(N1)”.
The model number is often printed in bold or larger font than other information on the label. It might also be accompanied by a manufacturer’s logo, such as LG Display, Samsung, AU Optronics (AUO), or Innolux.
Reassembling the Laptop
Once you’ve noted the model number, carefully reassemble the laptop in reverse order.
- Reconnect the screen cable.
- Snap the bezel back into place, ensuring all clips are securely fastened.
- Replace any screws you removed.
- Reinstall the battery and reconnect the power adapter.
- Power on your laptop to ensure everything is working correctly.
