How to Troubleshoot a Computer Laptop that Won’t Turn On

A PC notebook passes through a series of “won’t start” stages. The difficulty is made worse by the fact that a laptop has two power sources: When there isn’t any AC, the laptop’s battery is used to provide power. So you know right away that if your laptop doesn’t switch on right away, it’s because of a power supply problem. You have a power supply problem if the laptop looks to be dead. Follow these steps to troubleshoot:

Sources of power

  • Check to see if the laptop is connected.
  • Check to see that the battery is securely fastened.
  • Remove the battery and run the laptop solely on AC power. If it works, you might have a bad battery that has to be replaced.
  • Instead, if you have a spare battery, use it.

Adapters for AC cords

Check the AC cord’s power brick. Is this the correct adapter for your computer? Other portable devices may have adapters that seem similar, but they won’t work unless they match the volts and amps for your laptop. (It’s not like it’s ever happened to me.)

Examine the lamps

When the laptop’s power lamp is illuminated, it means the laptop is still operational. It indicates that the laptop’s hardware has detected the presence of power. It’s possible that the issue is with the laptop’s hardware rather than the power supply.

You can check both the AC power and the battery on your laptop if it has separate bulbs for each. It’s a battery problem if the AC lamp turns on but the battery doesn’t. The AC power brick may be dead, the AC power from the wall may be screwed up, or you may have a connection issue if the battery lamp is lit but the AC lamp remains black.

Hardware analysis

You can try testing some devices if you feel yourself to be technically competent. Check to see if the laptop’s removable disc drives are correctly attached, for example: Remove the drives and replace them while the laptop is turned off. The same goes for the PC’s memory card: Turn the laptop off, remove the memory, and then replace it.

When a laptop is broken, it will not turn on. I’m not being sarcastic when I say that laptop hardware can fail. Most laptop warranties cover malfunctioning electronics. You must contact the laptop manufacturer for assistance.

Is it possible that it has something to do with the display?

Toggle the Caps Lock switches on. The Caps Lock lamp on the laptop will flicker on and off as you press the key if you have power. If that’s the case, the issue could be with the display.

Examine the brightness settings on your laptop’s display. The screen will be dark if the brightness is set down too low, especially in a bright room or in direct sunlight. To see if the screen lights, turn the brightness all the way up.

Connect an external monitor to the monitor port on the laptop. If the external monitor displays properly, the issue is with the laptop’s display, not the laptop’s display adapter or any internal components. Because the laptop and monitor are the same things, replacing significant laptop components is required to fix the monitor (or the display adapter). For repairs, the laptop must be returned to the dealer.
