L2008-E2009

820-2330 C7771 loses capacitance and lowers the voltage. This can cause no boot.

M2009

820-2532, 820-2610 C7771 loses capacitance and lowers the voltage. This can cause green light but no power or 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

2011

820-2915 AMD GPU fails due to thermal issues. Bypassing is the only way to fix.

2012

820-3330

@ChrisB for A1286 commons issues 2009: C7771 only applies to 820-2532. Also affects A1297 820-2390 and 820-2610. I can cause no power with only 0.3V on the MCP standby rail, but could also cause some random instabilities.
