Overview
This Lenovo V15-IIL came in after failing to power on despite multiple reset attempts at home. The customer mainly wanted reliable startup and safe access to their files.
Symptoms
- No power-on response and persistent black screen
- Reset attempts and charger checks did not resolve the issue
- Concern about possible data loss
Diagnosis
Bench testing showed the problem was not a simple charger fault. We found motherboard-level issues and a BIOS state that needed correction before the system could initialise consistently.
Fix
We serviced the board, replaced small failed components, updated the BIOS, and completed a full internal dust clean while the laptop was open.
Result
The Lenovo booted normally again with no recurring startup fault during post-repair checks. User files remained accessible.
Prevention / Tips
If a laptop repeatedly fails to power on, avoid repeated forced starts. Book diagnostics early to prevent avoidable board damage.
