Computer & device

Laptop or computer won't turn on

1. Power: plug in the charger and check the charging light. Try a different power point, and make sure the charger is pushed in firmly at both ends.
2. Wait: a completely flat laptop may need 15 to 30 minutes of charging before it starts.
3. Hard reset: with the charger plugged in, hold the power button for 15 to 20 seconds, let go, then press it once normally.
4. Is it actually on? If you hear the fan or see lights but the screen is black, try the screen brightness keys, close and open the lid, or press Windows key + Ctrl + Shift + B (Windows restarts the display).
5. Unplug extras: remove USB drives, docks and other devices, then try again.

Still nothing?
