Try these first
- Check the adapter is fully plugged in and the charge light is on; try another socket.
- Unplug all USB devices and external displays.
- Hold the power button for 20–30 seconds, release, then try to start normally.
- If lights come on but the screen stays black, connect an external monitor.
What the symptoms tell you
- No lights at all: adapter, charging port or the board's power circuit.
- Lights and fan on but no picture: screen, display cable, RAM or graphics.
- Turns on then off: overheating protection or a power fault.
- After liquid damage, don't charge it — bring it in as soon as possible.
When to bring it in
If these steps don't help, the device needs a diagnosis. In most no-power cases your data can be saved — bring it in without opening it yourself.
