19) CLR_CMOS (Clear CMOS Jumper)
UsethisjumpertocleartheBIOScongurationandresettheCMOSvaluestofactorydefaults.Toclear
the CMOS values, use a metal object like a screwdriver to touch the two pins for a few seconds.
• Always turn off your computer and unplug the power cord from the power outlet before clearing
the CMOS values.
• After system restart, go to BIOS Setup to load factory defaults (select Load Optimized
Defaults)ormanuallyconguretheBIOSsettings(refertoChapter2,"BIOSSetup,"forBIOS
congurations).
Open: Normal
Short: Clear CMOS Values
20) 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.
CPU: CPU status LED
DRAM: Memory status LED
VGA: Graphics card status LED
BOOT: Operating system status LED
