Laptop Smart Card not detected at boot

4.5

The BitLocker screen asks for a card but doesn't see the one inserted.

Symptoms
  • "Insert Smart Card"
  • No activity light
  • Boot hang
Possible Causes
  • Reader not initialized
  • Dirty contacts
  • BIOS setting

Step-by-Step Fix

1

Clean Card Contacts

Use a soft cloth to wipe the gold chip.

2

Enable USB in BIOS

If the reader is USB, ensure USB is enabled at boot.

3

Try External Reader

Rule out the internal reader hardware.

When to See a Technician

Ensure "Legacy USB Support" is enabled in BIOS so the reader works before Windows loads.
