Your motherboard, processor, and video card may require a different power supply if your computer won’t turn on. Make sure the power supply meets the motherboard’s, processor’s, and video card’s requirements.

Ensure that you plugged the correct power supply into your laptop. AC adapters for laptops sometimes look the same, and if the power supply does not allow enough voltage and amperage, the laptop won’t operate.

Power supply failure, battery, motherboard failure, graphics card failure, or memory failure may result in your laptop not starting up even while plugged in.

  2. The remaining power on the laptop can be depleted by holding down the power switch for thirty seconds.

Diagnosing Screen Problems

  1. Make sure that any external display devices such as projectors and monitors that are not needed are disconnected before you begin to start your laptop.
  2. Try turning out the lights and turning on the power switch if you don’t see a faint image despite hearing fans or noise.
