What the symptoms may tell you
No lights or fan differs from lights with a blank display, and both differ from a Windows recovery screen. Those clues guide the next safe check.
Safe checks to try first
- 1Check the power outlet, adapter and cable for obvious damage; use only a compatible supply.
- 2Disconnect removable peripherals and note whether charging lights, fans or keyboard backlight appear.
- 3If the screen stays dark, try an external display only if you already have a safe compatible connection.
What to avoid
Do not open or charge a swollen or liquid-damaged laptop. Do not repeatedly restart a machine whose drive is clicking or holding unique data.
Next step
Send the model, charger specification, what lights appear and the last thing shown on screen.
What I can help with
Battery and selected component repairs are model-checked; board-level power repair is outside scope.
