No power and no display are different faults
A laptop can be completely dead, receive power but fail to start, or start internally while showing no image. Identifying which state is present avoids replacing unrelated parts.
Symptoms we diagnose
- No lights, fan movement or charging response
- Charging light present but power button has no effect
- Fan starts briefly and the laptop switches off
- Power lights appear but the screen remains blank
- Repeated restart loop or diagnostic blink codes
Possible causes
The adapter, battery, charging port, memory, display path, BIOS, motherboard power rails or a shorted component can cause similar behaviour. We begin with external power checks and move to internal diagnosis only as needed.
Clear repair decision
Once the likely fault is isolated, we explain whether the practical solution is component replacement, board-level repair or data retrieval. Repair approval is obtained before chargeable work begins.
Important
Final cost and turnaround depend on the exact model, fault and parts availability. We confirm the available route before beginning the repair.
