Why Won't My Laptop Turn On?

Practical checks

Start with the basics.

1. Remove the charger and hold the power button for the normal discharge procedure, then reconnect and try again if appropriate.
2. Check the adapter, cable and socket for damage or loose connections.
3. Look for charging lights, fan noise or keyboard backlight. These clues show whether the laptop is receiving power.
4. If the laptop powers on but the screen stays black, connect it to a known-good external display when possible.
5. Repeated failure to start deserves a safe professional diagnosis.
