CPU/DRAM/VGA/BOOT (Status LEDs)
The status LEDs show whether the CPU, memory, graphics card, and operating system are working
properly after system power-on. If the CPU/DRAM/VGA LED is on, that means the corresponding device
is not working normally; if the BOOT LED is on, that means you haven't entered the operating system yet.
