Quick answer
No power does not prove that the motherboard has failed. Start with the external power source and correct adapter, then have the internal power path assessed if needed.
Understand the issue
This guide covers dead laptop repair. The useful starting point is to establish what happens, when it happens and whether recent changes are involved. Keep the original symptom separate from a proposed repair: a symptom alone rarely identifies the exact part or setting at fault.
Useful details to discuss
- Initial fault diagnosis and symptom assessment
- Component or software testing
- Repair, replacement, installation or configuration where appropriate
- Performance and stability checks after service
- Advice on backup, maintenance and prevention
Step-by-step checks
- Check the power source and compatible cable.
- Disconnect accessories and record any brief indicator activity.
- Stop when there is heat, smell or visible damage.

What the results mean
Do not open a desktop power supply or bypass protection circuits. Internal components can remain hazardous after disconnection.
| Stage | Action |

Frequently asked questions
Does a power light prove the computer is working?
It shows that some power is present. Startup and stable power under load still need to be checked.
What should I record before requesting help?
Record the full model, exact error or symptom, recent changes and what you already tried. Explain whether important files have a separate backup.
How do I arrange a repair assessment?

Conclusion
Start with the evidence and compare it with the symptom before choosing a repair. Do not open a desktop power supply or bypass protection circuits. Internal components can remain hazardous after disconnection. If the checks do not explain the problem, share your observations and ask for an assessment before approving work.
