Power Down The Laptop And Remove The Battery
Before starting the screen replacement process, it is essential to power down your Lenovo T490 laptop and remove the battery. This step is crucial to ensure your safety and prevent any potential damage to the device.
To power down the laptop, go to the Start menu on your desktop and click on the Power icon. Select the “Shut Down” option and wait for the laptop to completely power off.
Next, locate the battery release latch on the bottom of the laptop. Slide or push the latch to unlock the battery, then carefully lift it from the compartment.
Removing the battery eliminates any risk of electric shock during the screen replacement process. It also allows for easier access to the internal components of the laptop.
Make sure to keep the battery in a safe place while working on your laptop. Once you have completed the screen replacement, you can easily reinsert the battery and power on the device to test the functionality of the newly replaced screen.
Remove The Bezel And Disconnect The Screen Cable
When it comes to replacing the screen on your Lenovo T490, the first step is to remove the bezel. The bezel is the plastic frame surrounding the screen, and it is held in place by small clips or screws. Start by carefully prying off the bezel using a plastic pry tool or a small flathead screwdriver. Take your time and make sure not to apply too much force, as you don’t want to damage the bezel or the screen.
Once the bezel is removed, you will see the screen cable connected to the back of the screen. This cable transfers the display data from the motherboard to the screen. To disconnect the cable, locate the small latch or connector at the end of the cable near the screen and gently lift it up. This will release the cable from its connector. Be cautious while doing this step and handle the cable with care to avoid any damage.
With the bezel removed and the screen cable disconnected, you are now ready to proceed with removing the old screen and installing the new one.
Remove The Old Screen From The Laptop
When it comes to replacing the screen on your Lenovo T490, removing the old screen is a crucial step in the process. To begin, carefully detach the screen bezel by gently prying it up using a plastic opening tool. Work your way around the edges until the bezel is completely separated from the display assembly.
Once the bezel is removed, you will have clear access to the screen. Be cautious as you disconnect the screen cable from the back of the panel. Most likely, it will be connected via a small connector or ribbon cable. Take note of how it is connected so you can easily reconnect the new screen later.
Now that the screen cable is detached, carefully remove any screws securing the screen in place. There may be multiple screws around the perimeter of the display or along the sides. Once all screws are removed, gently lift the old screen out of the laptop, being mindful not to damage any other components.
By following these steps, you will successfully remove the old screen from your Lenovo T490 and be ready to install the new one.
Install The New Screen And Reconnect The Screen Cable
Now that you’ve successfully removed the old screen from your Lenovo T490, it’s time to install the new screen. Begin by carefully positioning the new screen onto the laptop’s frame, making sure that it lines up properly.
Next, gently reconnect the screen cable to the appropriate port on the back of the screen. Take care not to apply excessive force, as this can damage the delicate connectors.
Once the cable is securely connected, carefully lower the screen into the laptop’s frame, ensuring that it fits snugly. Double-check that all the edges align correctly.
After the screen is properly aligned and the cable is connected, it’s time to move on to the final steps of the replacement process. But first, make sure to clean the screen with a microfiber cloth to remove any fingerprints or smudges before securing the bezel.

Replace The Bezel And Secure It In Place
Replacing the bezel is the next step in replacing the screen on your Lenovo T490 laptop. The bezel is the frame that surrounds the screen and holds it in place. To replace the bezel, follow these steps:
1. Take the new bezel and align it with the laptop’s frame. Ensure that all the tabs on the bezel are correctly positioned.
2. Gently press the bezel onto the frame, starting from one corner and moving along the edges. Make sure it fits securely and snaps into place.
3. Once the bezel is in position, use a plastic spudger or a flat, non-metallic tool to push down all the clips along the edges. This will help secure the bezel firmly to the laptop.
4. Take your time while pressing down the clips to avoid any damage to the new screen or the bezel itself.
By replacing the bezel and securing it properly, you ensure that the new screen stays in place and provides a seamless viewing experience. Now that the bezel is in place, you can proceed to the final steps of reinserting the laptop battery and powering on the device.
