“Hey dear, don’t play with the laptop! No! No! No!”
Oh! Shit! Heart breaks. The laptop is unusable due to the cracked screen.
Ok, let me fix it by myself.
The backlight of the LCD of my laptop is LED type. Different model with different internal hardware. Here it only takes my laptop for example.
Before fixing, we shall check if the laptop is still under warranty period. If yes, you don’t need to fix it by yourself.
Note: Don’t do that you are not sure of.
Buy a good screen that matches the broken one exactly first and prepare some tools.
Remove the frame (bezel) carefully and take the broken screen away. Keep the step and instruction in your mind.
Discard the broken LCD board.
Judge by the step that you removed the frame just now, position and install the new LCD. Make sure that you use right screws.
Don’t be in a hurry to install the frame again. Test your new LCD to check if it works. Install the frame at last to protect the screen.
