Opening the Case

  • Begin by completely unplugging the system from everything. No ports should be connected, especially AC power.
  • Remove the two screws from the sides and slide the lid off towards the rear.

Clearing the CMOS

Performing a CMOS clear can resolve various boot and power issues. It will also reset the BIOS to factory defaults.

  • Locate the clear CMOS pins. They are marked with an arrow in the following two images.
  • Using a screwdriver or other conductive tool, short the two pins for ~30 seconds.
  • Re-assemble the unit and power it on. Do not touch the unit for 2 minutes. It may restart itself multiple times to reconfigure the CMOS. If the unit is still unresponsive after 2 minutes, contact OnLogic support for further instructions.
