I worked on the ASUS North America Technical Support account for over 7 years, while there my primary role was to handle escalated troubleshooting of products and their various issues, returned products for repairs and dealing with unhappy customers for varying reasons.
I was expected and executed solutions to all their Windows based devices (Laptops, Desktops & AIO etc.), Android based devices (Phones, Tablets, Chromebooks).
However my main department was the Component Support, which I assisted with Troubleshooting Motherboards (Pre-sales, Compatibles with various devices and getting them to POST), Network Devices (Wired/Wireless Routers, Switches, Mesh Systems etc.) Servers/Sever Hardware and many other Peripherals both internal and external.
