2008-2009
820-2330, 820-2390, 820-2532, and 820-2610
- C7771 loses capacitance and lowers the voltage. This can cause green light but no power or some random instabilities. It can cause no power with only 0.3V on the MCP standby rail, but could also cause some random instabilities.
820-2523 and 820-2533 are not affected
2010
820-2850
- C9560 loses capacitance and lowers the voltage. This can cause intermittent crashing especially when switching graphics processors. It can also cause no video
820-2849 is not affected.
2011
820-2914, 820-2915
- AMD GPU fails due to thermal issues. Bypassing is the only way to fix.
