This is a guide on replacing the LCD on an IBM-Lenovo Ideapad B50-45 laptop.
To perform this replacement, you will need a size 0 or 1 Phillips head screwdriver, and a new LCD screen.
Then, remove the battery as shown on the case. Note, that there is a locking clip that you may need to slide to the side first.
There are no screws that hold the bezel. Insert your fingers between the LCD and the bezel, and carefully start working your way around the assembly. Be sure to not apply to much force.
Once the bezel is separated, put it aside.
The screen is held by only four screws, one in each corner. You only need to remove the screws that are holding the screen clips.
Put the old screen aside. Cover the keyboard with a cloth or a plastic bag to prevent the new screen from being scratched or otherwise damaged.
At this point the new screen can be installed.
Place the new screen on the keyboard. Reattach the video cable using both hands. Make sure it is not twisted or slanted, it must be plugged in straight.
Secure the video connector with the tape. If the tape is worn, it may be a good idea to add some extra tape for safety.
Reattach the bezel by pushing the clips back in with your hands. Work your way around to make sure all clips are connected. Flip the laptop over and make sure that the bottom edge is also snapped in.
