2. Disconnect or remove any peripherals connected to the laptop and yen connect the charger to the PC.
3. Check that the LCD screen is clean and there is no dust particle on it.
4. Now Press and hold the D key and the power button on your laptop.
5. This will take you to  LCD built-in self-test (BIST) mode. Keep holding the D key till the screen changes its colors.
