When your 5-year-old laptop dies it’s usually time for a replacement. But [Andrew Menadue]’s Novena laptop is fully open-source. He has full access to all the documentation, so he decided to try his hand at repairing it instead. The power supply circuit board went up in smoke one day — he attributes this to poor battery health due to him not using it frequently enough. Given his usage pattern, he decided to switch the Novena into a desktop machine.
He made the conversion with a new pass-through power supply board, and the computer booted up but with no display.
