Overview
A customer in Wimbledon brought in an Acer laptop that had stopped powering on. The root cause was in the charging input stage rather than the adapter.
Symptoms
- Device dead on battery and mains
- No reliable charging indication
- Intermittent behaviour before full failure
Diagnosis
The DC jack in this model was board-mounted, and testing showed a hardware fault at that connector point.
Fix
We performed a careful de-solder of the failed jack, fitted a replacement component, and re-tested power delivery and charging reliability.
Result
The laptop powered up normally and maintained stable charging after repair.
Prevention / Tips
Use quality chargers and avoid cable strain at the port to reduce repeat motherboard-level jack failures.
