CMOS Clear
JBT1 is used to clear the CMOS. Instead of pins, this jumper consists of contact pads to
prevent accidental clearing of the CMOS. To clear the CMOS, use a metal object such as a
small screwdriver to touch both pads at the same time to short the connection.
To Clear CMOS:
1. First power down the system and unplug the power cord(s).
2. Remove the cover of the chassis to access the motherboard.
3. Remove the onboard battery and the external CMOS battery installed on J18.
4. Short the CMOS pads with a metal object such as a small screwdriver for at least four
seconds.
5. Remove the screwdriver (or shorting device).
6. Install the batteries, the cover, reconnect the power cord(s), and power on the system.
Note: Clearing CMOS will also clear all passwords.
