Laptop BitLocker not compatible with hardware
4.5
BitLocker says your hardware doesn't meet the security requirements.
Symptoms
- "TPM not found"
- "Hardware not supported"
- Error code
Possible Causes
- No TPM
- Legacy BIOS
- Unsupported CPU
Step-by-Step Fix
1
Enable TPM/Secure Boot
Check BIOS for these settings.
2
Use Software Encryption
Enable BitLocker without TPM via Group Policy (requires a USB key to boot).
3
Update BIOS
Ensure the latest security features are unlocked.
When to See a Technician
You can bypass the TPM requirement using Group Policy, but you'll need to plug in a USB key every time you start the laptop.
