Avanti - PC Repair Instructions - Asus


Avanti used Asus PCs in some of the early Executive/ tabletop kiosks before switching exclusively to Dell in 2016. These PCs are prone to overheating and will need the CMOS battery replaced for all warranties. In most cases, the PC will need one or more of these components replaced:

  • HDD replacement and reimaging
  • CMOS battery replacement/ reconfiguring BIOS
  • CPU fan replacement
  • Application setup and registered to Slabb Pipeline Org

If either the motherboard has failed or the PC cannot otherwise be repaired, replace it with a new PC kit: imaged micro PC, power supply, and HDMI-VGA adapter.

Include a power supply and HDMI adapter if cross-grading from small form factor to micro PCs or an Asus > Dell PC.


For replacement HDDs, any SATA III SSDs will work. Both Asus models use the same external power supply model: PA-1650-78 (65w), USB-Ethernet adapters for secondary NIC, and VGA for primary video output.
