Laptop encryption password not accepted after update
4.5
Your known encryption password is rejected following a Windows or BIOS update.
Symptoms
- "Incorrect password"
- Locked out
- Recovery key required
Possible Causes
- Keyboard layout change
- TPM reset
- BIOS bug
Step-by-Step Fix
1
Check Keyboard Layout
Ensure the layout at the boot screen matches your password (e.g., QWERTY vs AZERTY).
2
Use Recovery Key
Enter the 48-digit recovery key to regain access.
3
Roll Back BIOS
If a BIOS update broke the TPM link, rolling back may fix it.
When to See a Technician
Updates sometimes reset the keyboard layout to US English; if your password has symbols, they might be in different places.
