Motherboard / Mainboard Assembly
The Ideapad 3 series frequently suffers from localized shorts in the CPU power rail (PC3001) or failure of the BQ-series charging IC. Because these components are surface-mounted and require advanced microsoldering, the standard field service resolution is a full board replacement. This solves the issue of fluctuating voltages at the entry MOSFETs (PQ100/101) that prevent battery induction.

Internal Battery Pack (3-Cell Li-ion)
A depleted or chemically failed battery can trigger internal protection circuits that prevent the charging MOSFETs from opening. If the laptop powers on with the AC adapter but shows 'plugged in, not charging,' the battery's internal controller has likely flagged a permanent failure.

DC-In Cable / Power Jack
Physical fatigue or oxidation at the DC jack pins can cause high resistance, preventing sufficient current flow to trigger the charging circuit. This is a common mechanical failure point in consumer laptops that are frequently moved while plugged in.
