18. TPM header
The TPM header allows you to connect a TPM module, which securely stores keys,
digital certificates, passwords, and data. A TPM system also helps enhance network
security, protect digital identities, and ensures platform integrity.
The TPM module is purchased separately.
19. Q-LEDs
The Q-LEDs check key components (CPU, DRAM, VGA, and booting devices) during
the motherboard booting process. If an error is found, the critical component’s LED
stays lit up until the problem is solved.
The Q-LEDs provide the most probable cause of an error code as a starting point for
troubleshooting. The actual cause may vary from case to case.
