Short answer: “Will not turn on” is not one fault. Check power first. No fan or light is the power path; fan but no picture is display-side; logo but no Windows is disk or system. Work in order — do not swap parts at random.
1) No response at all
- Socket, cable, (on a desktop) the PSU switch
- On a laptop, try it with the adapter in; another adapter if you can
- Hold the power button 20–30 seconds, then try again
If it is still dead, the power socket, battery or board power line is more likely.
2) Fan spins, screen stays black
- Try an external monitor (HDMI / VGA)
- RAM may be loose or failed
- The panel or the board can also be the cause
3) Logo appears, Windows does not
- Blue screen / endless loading: disk or system
- SSD / HDD failure is common
- If the data matters, do not format at random; diagnose and back up first
FAQ
