Symptoms
- Charging light only comes on when the cable is angled a specific way
- Small movements of the laptop or cable interrupt charging
- Charging cuts out if the laptop is bumped
- Problem is worse with one cable than another
Likely causes
- CommonWorn or loose charging port connectorRepeated plugging in at slightly different angles wears down the internal contacts.
- CommonDamaged cable near the connectorCables often fail right where they bend into the plug.
- PossibleBent pin inside the portA single bent pin can require exact alignment to make contact.
- PossibleInternal port has come loose from the motherboardCommon after the cable was yanked or the laptop was dropped while plugged in.
What to do
- Try a different cable and charger first to see if the problem follows the cable or stays with the laptop.
- Inspect the cable near the connector for kinks, fraying, or a visibly bent tip.
- Look inside the laptop's port with a flashlight for a bent pin, without inserting anything metal.
- Note the exact angle that works, which can help a technician quickly diagnose the fault.
- Avoid using the laptop while resting the cable at that angle for long periods, since it puts stress on the connection.
- Stop relying on the workaround if the required angle gets more extreme over time, since it points to worsening damage.
