The capacitor plague is a problem with a large number of premature failures of aluminum electrolytic capacitors with non-solid or liquid electrolyte of certain brands, especially from some Taiwanese manufacturers.The first flawed capacitors were reported in 1999, but most of the affected capacitors failed in the early to mid 2000s. High failure rates occurred in various electronics equipment, particularly motherboards, video cards, compact fluorescent lamp ballasts, LCD monitors, and power supplies of personal computers. News of the failures (usually after a few years of use) forced many equipment manufacturers to repair the defects. The problem seems to be ongoing; faults were still being reported as of 2010.PrevalenceFaulty capacitors have been discovered in motherboards as old as Socket 7 (1996), but mainstream electronics journals began reporting on widespread defective capacitors around 2003. Problems with "bad caps" have affected equipment manufactured up to at least 2007 and beyond. Many well-known motherboard companies have unknowingly assembled and sold boards with faulty capacitors sourced from other manufacturers. Major vendors such as IBM, Intel, Dell, HP, Samsung, and Apple Inc. were affected. The motherboards and power supplies in the Apple iMac G5 and some eMacs were also affected.
