Computer won’t turn on: practical checks

A computer with no signs of power may have a supply, battery, charging, display or internal hardware fault.

Likely causes

  • Failed adapters, power supplies, batteries, buttons, displays and mainboards are possibilities.

Safe checks you can make

  • Check cables and the wall socket, disconnect nonessential accessories and note lights, fans or sounds.
  • Do not open a mains-powered supply or repeatedly power a liquid-damaged device.

When to stop and get urgent help

  • Disconnect equipment that smells burnt, sparks, overheats or has suffered liquid ingress.

How a computer repair technician can help

  • A technician can distinguish a display problem from a power fault and protect storage devices during diagnosis.
