Laptop Won't Turn On
The laptop shows no lights, no fan noise and nothing on screen when you press the power button, or the power light comes on but nothing ever appears on screen.
Quick answer: A laptop with no response to the power button is usually a dead battery combined with a charger or port that isn't charging it — leave it plugged in for 15-20 minutes and try again. If the power light comes on but nothing appears on screen, that's more likely a screen or internal fault than a dead battery.
Likely causes
- Battery is fully dead and the charger isn't charging it
- Charging port or charger cable has failed
- Screen or backlight has failed while the laptop is actually running (it may be starting fine with no visible display)
- A failed internal component such as the motherboard or RAM
What you can safely check yourself
- Plug in the charger and leave it for 15-20 minutes before trying again, in case the battery is fully drained
- Check the charging light on the laptop or charger itself turns on when plugged in
- Try a different power outlet
- If you have an external monitor, try connecting it — if you get a picture there, the laptop may be running fine with a failed screen
If the laptop has taken a knock, been dropped, or had liquid spilled on it, avoid repeatedly trying to power it on — get it looked at before doing anything further.
When it needs a proper look
If the charging light never comes on with a known-good charger, or an external monitor also shows nothing, that points to an internal fault that needs proper diagnosis.
The charging light is on but the laptop still won't start — what does that mean?
That usually rules out a dead battery and points to something else — a screen fault, a failed internal component, or the battery no longer holding a full charge despite showing a charging light. It's worth having it diagnosed properly.
