Laptop SD Card Reader: fractured flex-cable trace. Repeated bending breaks one or more conductors.

The distinguishing clue

Card detection or transfer fails intermittently along a damaged card reader cable path.

Checks before an assessment

Record the card format and whether the same undamaged card is readable in another compatible reader. Cancel format prompts and do not force a card into the slot.

Stop point: Bent contacts can short a card or damage the reader.

Workshop confirmation and repair

Device-level check: Test known cards, inspect the slot and compare firmware with Windows detection.

Targeted check: Compare the failure pattern and check continuity without puncturing the cable. If confirmed: Replace the damaged flex or complete input module.

Repair boundary: Repair the slot, cable or controller path and confirm the supported card standard.

Related cause to rule out

When the device works intermittently after chassis movement, also consider Laptop SD Card Reader: loose internal flex cable before choosing a repair.

Checks after the work

After repair or replacement, check several cards, read and write transfer, eject and sleep recovery.
