I was using my laptop and all of a sudden it shutted down and when start it, it started for few minutes and then again it was shut down automatically
Now if i was pressing power button the light and fan were starting for an second and automatically closed so i tried detaching the battery and plugging in the ac adapter directly but it didn't work so i removed the ram and inserted it again and now the when i press the power button the lights turned on and fan is running but now i have lost my display
Now when i power on the laptop, screen is not glowing
