1. POST State LEDs
The POST State LEDs provide the status of these key components during POST
(Power-On-Self Test): CPU, memory modules, VGA card, and hard disk drives. If an
error is found, the critical component’s LED stays lit up until the problem is solved.
2. TPU LEDs (TPU_LED)
The TPU LEDs light up when you set the TPU switch to TPU_I mode or TPU_II mode.
