Steam Machine 'Red Line' LEDs indicate faults but are often fixable

Early Steam Machine owners reported a so-called "Red Line of Death" LED error, but many cases have been resolved with resets and BIOS updates. Valve's light-bar uses different widths and animations to indicate specific hardware issues like GPU failure or overheating. Steam's support documentation explains the meanings and notes critical error indicators override custom lighting.

• "Red Line" refers to LED error patterns
• Different bar widths/animations map to specific faults (GPU, overheating)
• Many issues resolved by resets and BIOS updates
• Valve support page documents light-bar meanings; critical errors override custom settings
