Fix: Basic laptop power reset

A laptop can get stuck in a frozen sleep or power state. A power reset clears that state without opening the laptop.

Quick answer

Unplug the laptop, hold the power button for 10–15 seconds, plug the charger back in, wait a minute, then press power once normally.

Important warning

Do not repeatedly press the power button quickly. Use one long press, then one normal press.

Try this

  1. 1 Unplug the charger from the laptop.
  2. 2 Unplug any USB devices, docks, monitors, and memory cards.
  3. 3 Hold the power button for 10–15 seconds.
  4. 4 Plug the charger directly into a wall outlet.
  5. 5 Connect the charger to the laptop.
  6. 6 Wait one minute.
  7. 7 Press the power button once normally.

Common causes

Laptop is stuck in sleep or hibernation.

A connected USB device or dock is preventing startup.

The power controller is stuck.

The laptop battery is deeply discharged.

What to check next

  • Check whether the charging light appears after reconnecting power.
  • Check whether the laptop starts with all USB devices removed.
  • Check whether the charger is plugged directly into the wall.
  • Check whether the laptop responds after waiting one minute.
