17. Thunderbolt header
The Thunderbolt header allows you to connect an add-on Thunderbolt I/O card
that supports Intel's Thunderbolt Technology, allowing you to connect up to six
Thunderbolt-enabled devices and a DisplayPort-enabled display in a daisy-chain
configuration.
The add-on Thunderbolt I/O card and Thunderbolt cables are purchased separately.
18. 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.
