Known Issues

No Power

Causes

Loose power supply connector on motherboard.

Solutions

Reflow/reattach power supply connector.

Disassembly Notes

Uses Torx T8 Screws throughout but only 6 screws are required for motherboard extraction. Many ribbon cables are used to connect peripherals to the board so patience is required.
