to securely store keys, digital certicates, passwords, and
data. A TPM system also helps enhance network security,
protects digital identities, and ensures platform integrity.

20. Q-LEDs
The Q-LEDs check key components (CPU, DRAM, VGA, and booting devices) during the
mothboard 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.
